HE ILLUSTRATED DICTIONARY OF GARDENING aims at being the best and most complete Work on Gardening and Garden Plants hitherto published. The aim is, indeed, a high one; but the Publisher, whose taste for Flowers has rendered the production a labour of love, has, on his part, spared no expense that the Typography and Illustrations should be of a very high class. It is to be hoped that earnest efforts to attain accuracy, by consulting the best Authorities, combined with no small amount of original research, have contributed to render the matter of the Work not unworthy of the form in which it is presented to the reader. The large number of Illustrations is an important feature; and it is believed that the figures quoted, and the references given to various works—in which more detailed information is contained than is desirable, or, indeed, possible, in these pages, on account of space—will greatly add to the interest and value of the work. Considerable trouble has been taken in revising the tangled synonymy of many genera, and clearing up, as much as possible, the confusion that exists in garden literature in connection with so many plants, popular and otherwise. In the matter of generic names, Bentham and Hooker's recently-completed "Genera Plantarum" has, with few exceptions, been followed; that work being the one which will, for a long time to come, undoubtedly remain the standard authority on all that relates to generic limitation. With regard to the nomenclature of species, I have endeavoured to consult the latest and most trustworthy Monographs and Floras, and to adopt the names in accordance with them. Now and then, certain plants are described under their common garden names; but they will, in such cases, be also found mentioned under the genus to which they really belong. A case in point may be cited: Anœctochilus Lowii is given under Anœctochilus, but the name it must now bear is Dossinia, and a reference to that genus will explain matters pretty fully, as far as the present state of knowledge goes.

I am greatly indebted to Professor J. W. H. TRAIL, M.D., F.L.S., &c., for his valuable contributions on Insects, Fungi, and Diseases of Plants, branches of science in which he has long been specially interested, and in which he is an undoubted authority.

Mr. J. GARRETT, of the Royal Gardens, Kew, late of the Royal Horticultural Society's Gardens, is responsible for Fruit and Vegetable Culture, for most of what appertains to Florists' Flowers, and for General Gardening Work. For information on many special subjects—Begonias may be cited as an example—I am obliged for much assistance to Mr. W. WATSON, also of the Royal Gardens, Kew; in fact, the article Begonia, in its entirety, was written by him. Mr. W. B. HEMSLEY, A.L.S., has, throughout, given me aid and advice; and I have to acknowledge constant help from several other colleagues.

The Rev. PERCY W. MYLES, M.A., has taken no little trouble in working out the correct derivations of very many of the Generic Names; unfortunately, in a number of instances, lack of time prevented me from obtaining the benefit of his knowledge. I have to record my gratitude for help in so difficult a task, this special study being one to which Mr. MYLES has paid much attention.

## THE
DICTIONARY OF GARDENING,

An Encyclopædia of Horticulture.

> The following are the Abbreviations used:—fl. flowers; fr. fruit; l. leaves; h. height; deg. degrees; rhiz. rhizomes; cau. caudex; sti. stipes.

> The Asterisks (*) indicate plants that are especially good or distinct.

A. In compound words from the Greek the initial a has usually a privative meaning; as aphyllus, without leaves; acaulis, without a stem, &c.

AARON'S BEARD. See Hypericum calycinum and Saxifraga sarmentosa.

AARON'S ROD. See Verbascum Thapsus.

ABELE TREE. White Poplar. See Populus alba.

ABELIA (named after Dr. Clarke Abel, Physician to Lord Amherst's Embassy to China, in 1817, and author of a "Narrative of a Journey to China" (1818); died 1826). ORD. Caprifoliaceæ. Very ornamental shrubs. Corolla tubular, funnel-shaped, five-lobed. Leaves petiolate, dentately crenated. Well suited for the cold greenhouse, either as trellis or pot plants; free-flowering when well grown, and of easy culture. May be treated in sheltered and warm climates as hardy; and can be grown out of doors during summer in less favoured spots. They thrive in a compost of peat and loam in equal parts, to which a small quantity of silver sand may be added. Increased by cuttings in summer, and by layers in spring, under a frame. Only two species, floribunda and rupestris, are much grown in England.

> A. floribunda (many-flowered).* fl. rosy-purple, about 2in. long, in axillary clusters. March. l. opposite, oblong. h. 3ft. Mexico, 1842. The best and freest flowering evergreen species.

> A. rupestris (rock).* fl. sweet-scented, small, pink, in pairs at the ends of the branches; sepals of leafy texture, with a reddish tinge. September. l. small, oblong. h. 5ft. China, 1844. A deciduous, branching, hairy shrub.

> A. serrata (serrate-leaved). fl. pretty pale red, sweet-scented, very large, in one-flowered terminal peduncles; sepals leafy. March. h. 3ft. China, 1844. A fine evergreen species.

> A. triflora (three-flowered).* fl. pale yellow, tinged with pink, small, arranged in threes at the ends of the branches; sepals long and linear, clothed with long hairs. September. l. small, lanceolate. h. 5ft. Hindostan, 1847. A small evergreen branching shrub.

ABERRANT. Deviating from the natural or direct way; applied, in natural history, to species or genera that deviate from the usual characters of their allies.

ABIES (from abeo, to rise; alluding to the aspiring habit of growth of the tree; or, according to some, from apios, a Pear-tree, in allusion to the form of the fruit). Spruce Fir. The synonymy of this genus is much confused, plants belonging to several genera being frequently referred to Abies in nurserymen's catalogues and gardening periodicals. ORD. Coniferæ. A genus of about twenty-five species, widely distributed over the mountainous regions of the Northern hemisphere. Cones cylindrical, or but slightly tapering, erect; catkins generally solitary; the carpels not thickened at the tip; and the leaves solitary, partially scattered in insertion, and more or less two-ranked in direction. Scales deciduous, falling off as soon as the seed is ripe, leaving the axis on the tree. All the species bear seeds at a comparatively early age; most are hardy. For culture, see Pinus.

> A. amabilis (lovely).* shoots rather rigid, furrowed with elongated cushions, covered with numerous small dark hairs. l. scattered, crowded, 1½in. to 2in. long; linear obtuse, dark green above, silvery beneath. The cones are described as cylindrical, and about 6in. long. h. 180ft. California, 1831. A magnificent conifer, very massive in appearance.

> A. baborensis.* l. linear, dark green, silvery on the under surface, very numerous, those of the larger branches shortly pointed, and those of the branchlets more obtuse and pointless, ½in. to 1in. long. cones erect, cylindrical, usually in clusters of four or five, 5in. to 8in. long, and about 2in. in diameter; scales reniform, greyish-brown, inclosing a thin, dry, and shrivelled bract. h. 40ft. to 60ft. Algiers, 1864. This is a very beautiful medium-sized tree. SYN. A. Numidica.

> A. balsamea (Balm of Gilead or Balsam Fir).* l. silvery beneath, apex emarginate or entire, somewhat recurved and spreading, ¾in. long. cones cylindrical, violet-coloured, pointing upwards, 4in. to 5in. long, and ½in. broad; scales ¾in. broad, and the same in length. h. 40ft. to 60ft. United States and Canada, &c., 1696. A medium-sized slender tree.

> A. bifida (bifid). Identical with A. firma.

> A. brachyphylla (short-leaved).* l. linear, spirally inserted round the branchlets, but pointing laterally in two directions, ¾in. to[2] 1½in. in length; lower ones longest, obtusely pointed or emarginate, bright green above, with two silvery lines beneath. cones 3in. to 4in. long, purple. h. 120ft. Japan, 1870. A recently introduced magnificent fir, with an erect stem, regularly whorled horizontal branches.

> A. bracteata (bracted).* l. rigid, linear, flat, distichous, 2in. to 3in. long, bright glossy green above, and glaucous beneath. cones about 4in. long, with the bracts developed into long rigid leaf-like linear spines, 2in. long, and slightly curved inwards. h. 25ft. Southern California, 1853. A very handsome tall slender tree, but, owing to its very early growth of new shoots, it is much injured by the spring frosts.

> A. Brunoniana (Brown's). Synonymous with Tsuga Brunoniana.

> A. canadensis (Canadian). A synonym of Tsuga canadensis.

> A. cephalonica (Cephalonian).* l. subulate, flat, dark green above, and silvery beneath, acute. cones erect, cylindrical, green when young, afterwards reddish, and brown when ripe, 5in. to 6in. in length, and about 1½in. in diameter; scales broad, thin, and rounded, shorter than the bracts. h. 50ft. to 60ft. Mountains of Greece, 1824. A very desirable tree for growing in exposed situations.

> A. cilicica (Cilician). l. linear, slightly curved or straight, 1in. to 1½in. long, dark green above, and glaucous beneath, crowded, in two ranks. cones cylindrical, 6in. to 8in. long; scales broad, thin, entire, coriaceous. h. 40ft. to 60ft. Mount Taurus, in Asia Minor. This species seldom produces a good specimen tree in England, and cannot, therefore, be recommended for general cultivation.

> A. concolor (one-coloured).* l. linear, flat, obtuse, glaucous green, distichously arranged in double rows, those in the lower rows 2in. to 3in. long, upper ones shorter, channelled above. cones cylindrical, obtuse both at base and top, 3in. to 5in. long, 2in. to 2½in. in diameter; scales numerous, imbricated, larger than the bracts. h. 80ft. to 150ft.

> A. excelsa (tall). A synonym of Picea excelsa.

> A. firma (solid).* l. rigid, coriaceous, spirally arranged around the branchlets, but point laterally in two directions, 1in. to 1¼in. long, very variable in young and old trees. cones cylindrical, obtuse at both ends, 3in. to 6in. long; scales imbricated, bearing protruding keeled bracts. h. 100ft. Japan, 1861. An erect tree, of great beauty.

> A. Fortunei (Fortune's). It is said that in its native country, its aspect is peculiar rather than handsome, and that but one living representative is believed to be in existence in this country—at Veitch's Nursery. SYN. Keteleeria Fortunei.

> A. Fraseri (Fraser's). Double Balsam Spruce Fir. l. linear, emarginate, silvery beneath. cones oblong, squarrose, somewhat leafy, obcordate, mucronate, half exserted, reflexed. h. 30ft. to 40ft. North Carolina, 1811. This species closely resembles A. balsamea, from which it differs in having shorter and more erect leaves, and smaller cones.

> A. grandis (splendid).* l. in double rows, on each side of the branchlets, flat, obtuse, emarginate, pectinate, silvery beneath, from ¾in. to 1in. long. cones lateral, solitary, cylindrical, obtuse at base and apex, 4in. to. 5in. long, 2in. wide; bracts ovate, acuminate, irregularly dentate, very short. h. 100ft. California, 1831. A handsome tree of symmetrical habit, and rapid growth.

> A. lasiocarpa (woolly-coned). Synonymous with A. concolor.

> A. magnifica (magnificent).* l. densely crowded, two-rowed, 1in. to nearly 2in. long, olive green, very glaucous on the upper surface when young, becoming duller with age, and marked with two silvery lines beneath. cones 6in. to 7in. long, 2½in. to 3in. in diameter; scales, outer edge incurved. h. 200ft. North California, 1851. A very tall and stately species, with, at successive intervals, whorls of horizontal branches.

> A. Mariesii (Maries'). l. erect, evenly disposed around the stem, linear-oblong, obtuse; apex notched, ⅓in. to not quite 1in. long; bracts ovate, oblong, retuse. cones erect, cylindrical, 3½in. to 5½in. long, 1½in. to 2in. wide, narrowed at the base and apex, blackish purple; scales entire, nearly 1in. wide, not quite so long as wide. Japan, 1879. A tall, pyramidal tree.

> A. Mertensiana (Merten's). Synonymous with Tsuga Mertensiana.

> A. miniata (vermilion). Synonymous with Picea eremita.

> A. Morinda (Morinda). Synonymous with Picea Morinda.

> A. nobilis (noble).* l. linear, mostly on one side of the branches, falcate, short, acute, silvery beneath, 1¾in. long. cones cylindrical, erect, sessile, 6½in. long, 2¾in. broad, brownish; scales triangular, without the bractea, 1¼in. long, and the same in breadth; bractea spathulate, imbricated backwards, ⅝in. long. h. 200ft. to 300ft. California, 1831. A majestic tree.

> A. Nordmanniana (Nordmann's).* l. linear, rigid, flat, and minutely bifid at the apex, on young trees spreading in two rows, with a half-twist at the base, 1in. long. cones erect, slightly ovoid, pedunculate, 4in. to 6in. long, and 2¼in. to 2¾in. wide; bracts large, coriaceous, three-lobed, fringed, greatly exceeding the scales. h. 80ft. to 100ft. Crimea, &c., 1848. A magnificent and stately tree, of regular growth.

> A. Numidica (Numidian). Synonymous with A. baborensis.

> A. pectinata (comb-like).* l. linear, solitary, flat, obtuse, stiff, turned-up at the points, two-ranked, ½in. to 1in. long, shining green above, with two lines of silvery white on each side of the midrib beneath. cones axillary, cylindrical, erect, 6in. to 8in. long, 1½in. to 2in. broad, when ripe, brown; scales with a long dorsal bractea, 1/6in. to 1¼in. long, and 1¼in. broad. h. 80ft. to 100ft. A very noble silver fir, of slow growth when young only. Central Europe, 1603. There are several unimportant varieties of this splendid species.

> A. Pindrow (Pindrow). In its native home, the Himalayas, this is a very beautiful tree, attaining the height of 150ft., but it has generally failed in England, in consequence of our late spring frosts destroying the young growth. It comes very near A. Webbiana, but is readily distinguished by its longer and more acutely bidented leaves, and smaller cones.

> A. Pinsapo (Pinsapo).* The Spanish Silver Fir. l. linear, disposed around the branches, nearly terete, and entire at the apex, not quite ½in. long, bright green, with faint silvery lines on the inner side. cones sessile, oval, or oblong, 4in. to 5½in. long, about 2in. wide; bracts short, concealed by the broad rounded scales. h. 60ft. to 80ft. South Spain, 1839. A very magnificent species, very regular and symmetrical in habit. The one or two varieties offered for sale are not desirable.

> A. polita (neat).* l. arranged spirally, short, erect, rigid, falcate, acute at the apex, tetragonal, but compressed. cones ellipsoid, 3in. to 4in. long; scales light brown, coriaceous, minutely notched at the edge.

> A. sachalinensis (Sachalin). l. in many rows, 1in. or very slightly more long, ¹/₁₂in. broad, twisted to one side, rigid, linear, obtuse. cones sessile, erect, cylindrical, bluntly rounded at the apex, 3in. long, 1in. wide; scales transversely oblong, reniform; margin inflexed, denticulate; bracts ½in. wide, ¼in. long, obovate, serrulate, terminating in a reflexed angular point, exceeding the scale. Japan, 1879. A tall pyramidal robust species.

> A. Schrenkiana (Schrenk's). Synonymous with Picea Schrenkiana.

ABRONIA (from abros, delicate; referring to its involucrum). Sand Verbena. ORD. Nyctaginaceæ. A small genus of seven species, mostly natives of California, four of which only are known in general cultivation. They are of a dwarf trailing habit, producing showy blossoms in dense verbena-like clusters. Corolla funnel-shaped; limb spreading. They succeed best in light sandy soil, in a position fully exposed; if well drained, the rockery is perhaps the best place. Increased by seeds, the outer skin of which should be peeled off before sowing; sow during autumn in pots of sandy soil, and keep in a frame until the following spring, when they may be placed in their flowering quarters; or by young cuttings, set in spring, and also in sandy soil.

> A. rufescens (rusty-coloured). fl. grey-velvety on the outside, dark purple on the inside. March. l. ovate; under surface brownish. h. 10ft. Cayenne, 1820.

ABUTILON (Arabic name for a plant analogous to the Marsh Mallow). ORD. Malvaceæ. Very showy, decorative, and free-growing shrubs, both for the greenhouse and outside culture. Calyx naked, five-cleft, usually angular; style multifid at apex. The many beautiful hybrids (of which Fig. 2 represents a group) now in cultivation, far supersede the true species. Cultivation: Few plants are more easily grown and worthy of liberal treatment than these. The best soil for them is equal parts turfy loam, peat, and leaf mould, with some gritty sand. They may either be grown in pots, or planted out; but in all cases thorough drainage is indispensable, as they require an abundance of water, and stagnancy must be guarded against. At the end of May they may be planted outside, when they will flower profusely through the summer. In a free growing and flowering state they enjoy weak manure water. From the latter part of autumn till early spring they may be kept almost dry without injury, though in a warm conservatory some of the later struck plants will go on flowering throughout the greater part of the winter; or plants may be specially prepared for winter flowering. They are admirably adapted for forming standards of various heights, from 2ft. to 6ft. Some of the taller sorts are very useful for training under roof rafters. As pillar plants, too, very loosely trained, so as to allow the upper and side branches to droop to a considerable distance from the pillar, they are very effective. Propagation: They strike readily from cuttings made[4] of the young wood, at almost any season; the best time, however, is early spring and September. Inserted in pots, in a compost of equal parts peat, leaf mould, loam, and sand, and placed in a temperature of from 65deg. to 70deg., they will then quickly root, and form good plants. Seeds may be sown in pans filled with soil as recommended for cuttings, and placed in a similar temperature. Those followed by a dagger (†) are the best for training to pillars, roofs, &c.

A free grower, and makes an excellent greenhouse plant. In sheltered positions, in the south-west of England, this species proves to be almost hardy. It requires to be freely pinched. A very continuous bloomer.

> A. Thompsoni (Thompson's). fl. striated yellow, large. Summer. l. small, vine-like, richly mottled with yellow and dark green. h. 3ft. or 4ft. Habit very neat and erect.

> A. vitifolium (vine-leaved).* fl. porcelain blue, large, cupped. May. l. cordate, five to seven lobed, assuming, towards the autumn, a fine golden hue. h. 30ft. Chili, 1837. This fine shrub, or tree, is hardy in Ireland and the south of England, but should have a protection from frost. It is not a fast grower.

ABYSSINIAN PRIMROSE. A common name for Primula Boveana (which see).

ACACIA (from ac, a point, in Celtic; or from akazo, to sharpen; many of the species are furnished with spines). See also Albizzia. ORD. Leguminosæ. Shrubs or trees, very variable in habit and leaves. Flowers yellow, white, rarely red, disposed in globular heads or spikes, decandrous or polyandrous. Spines stipular, scattered, or wanting. This is a very polymorphous genus, and the majority of species described are known in this country only from herbarium specimens. It is very doubtful whether the entire genus is represented in our gardens by more than about fifty species, many of which are only to be found in botanic gardens; but this number is, without doubt, sufficiently characteristic. The number of species is close upon 400, and the genus one of the largest known. In our enumeration, we have strictly confined ourselves to describing such as are unquestionably in cultivation, and to this end we have adopted the only accurate method of deciding which are and which are not grown, viz., by consulting the trade lists of nurserymen, both in this country and on the Continent. Such lists, however, are not always correct, from a scientific point of view, in the matter of nomenclature. The species best deserving of cultivation are all natives of Australia, New South Wales, or other temperate regions, and are among the hardiest and most easily cultivated of all greenhouse plants. They are very floriferous. The greenhouse species are sufficiently hardy to withstand the winter in a temperature very little higher than freezing point. Cultivation: Some have a tendency to make long straight shoots; these should be selected for training upon rafters or pillars, on which they thrive well and form splendid ornaments in spring; whilst the more shrubby kinds will be equally at home in pots in the form of bushes. Roots and tops grow with great rapidity, and an abundance of water is required at all times. Immediately after flowering (usually about May) is the best time to prune Acacias; they may then be placed in the open air, and fully exposed to the sun, until October. They make a far healthier, cleaner growth, and ripen their wood much better outside than under glass; all they require is copious waterings, never allowing them to become dry, and keeping clear of weeds. In the first week in October house the plants, and winter in a temperature of 40deg. to 50deg. They delight in a light rich compost of equal parts turfy loam and leaf mould, freely intermixed with sand, or peat may be used instead of the leaf mould. Propagation: Cuttings of the half-ripened wood, put in with a heel, root readily during the summer. They do not bear heat well, nor do they require it. The soil should be equal parts peat and sand, covered with pure sand, thoroughly consolidated. Insert the cuttings as soon as made; water home, and leave them in the shade till dry. Then place the bell glasses over them, shade and water so as to prevent flagging. Pot off as soon as rooted, and keep in a close pit or house until the plants are thoroughly established. Seeds should be sown as soon as ripe, in sandy peat; about ¼in. deep, or a little more, for large seeds. A temperature of 55deg. to 60deg. suits them well. Pot off when large enough to handle, and place in a cool close pit or house until quite established. The culture and propagation of the stove species are the same as for the greenhouse sorts, but the former require, of course, greater heat. Their flowers, however, are much less frequently produced than their more temperate congeners, consequently they are not so much grown.

Flowers capitate, or interruptedly spicate, uninteresting; petals absent. Leaves alternate, impari-pinnate. Excepting for rockwork, or as edgings to flower beds, they are not of much value; their habit is, however, very compact and neat. They require similar treatment to other hardy herbaceous plants, in ordinary soil. Increased by cuttings, creeping rootlets, divisions, and by seeds.

> A. microphylla (small-leaved).* fl. green, small, in close heads, furnished with showy, long crimson spines. Summer. l. small, pinnate. h. 1in. to 2in. New Zealand. A neat evergreen with a compact and cushion-like growth; it is a very effective subject for the rock garden, and grows freely in most situations. The crimson globular heads of spine-formed calyces form a conspicuous and ornamental feature of the plant. SYN. A. Novæ Zealandiæ. See Fig. 6.

> A. millefolia (myriad-leaved).* fl. inconspicuous. A very distinct species with finely-cut pale green leaves. The fruiting spikes of this are not collected in globular heads, as in the others, and their presence detract from its value as an ornamental plant. Otherwise, it is very graceful.

ACALYPHA (the name given by Hippocrates to the Nettle). ORD. Euphorbiaceæ. Stove ornamental and variegated nettle-like leaved shrubs. Flowers greenish or reddish, inconspicuous, in erect or drooping bracted axillary or terminal spikes; those of the upper portion sterile, of the lower, fertile. The undermentioned only are those most worthy of cultivation. They are very easily grown, with ordinary stove treatment, and in a peat and loam compost. When well cultivated, the leaves of the hybridised varieties are highly coloured, but rather coarse than otherwise. Increased by cuttings under a glass in sandy soil, in stove heat, during April.

Flowers rather large, racemose, few; sepals combined in a broad oblique pitcher, including the petals, which are adnate to the base of the column; column short, produced into a long foot. Pseudo-bulbs oblong. Leaves few, large, longer than the scapes. The best species are the two first-mentioned. They will thrive well in sandy peat, with a quantity of small stones, broken pots, or gravel. A great deal of heat and moisture are absolutely essential during the growing period. Propagated, as soon as growth commences, by dividing the pseudo-bulbs.

> A. bicolor (two-coloured).* fl. purple and yellow, about 2in. long, campanulate, produced in clusters of three or four together; petals oblong-lanceolate, acutish; lateral lobes of lip rounded. June. h. 9in. Ceylon, 1833.

September. h. 1½ft. Java, 1843.

> A. sylhetense (Sylhet). fl. white, with many irregular spots and blotches towards the extremities of the outer portions. June. h. 9in. Sylhet, 1837.

ACANTHOLIMON (from akanthos, a spine, and limon, sea lavender). ORD. Plantagineæ. Dwarf hardy tufted evergreen plants, distinguished from allied genera in having sharp-pointed rigid leaves. They are of rather slow growth, thriving best in a sandy soil, and sunny position, on rockwork more particularly. The flowers are similar to Statice and Armeria. Increased by seeds (which germinate slowly), sown carefully on a warm but rather shaded border, and transplanted when large enough to handle; or by cuttings and very carefully made divisions. The cuttings should be made in late summer, and placed in a frame, to remain there during the winter.

They may remain in this soil for two or three years.

> A. crinita (hairy).* fl. spirally arranged, in threes, the central one being female. l. the fronds are arched, broadly ovate in outline, pectinately pinnate in division, with long linear acuminate segments, paler beneath. The stem is densely armed with black, needle-shaped spines, and much swollen towards the base. Seychelles, 1868.

ACANTHORHIZA (from akantha, a spine, and rhiza, a root). ORD. Palmæ. A small genus of stove palms, differing from Trithrinax by the aërial roots of the trunk hardening into spines (which are horizontal or pointed upwards), and by the blade of the leaf being divided down to the petiole. They delight in a rich loamy soil, and are propagated by seeds, in a moist, sweet hotbed, in spring.

> A. aculeata (spiny).* l. orbicular, palmately slit into numerous linear-lanceolate, glabrous segments, deep-green above, silvery beneath; petioles slender; the trunk is covered with a network of branching spines. Mexico, 1879. SYN. Chamærops stauracantha.

ACANTHUS (from akanthos, a spine; several species being spiny or prickly). Bear's Breech. ORD. Acanthaceæ. A group of stately, ornamental perennial plants, mostly hardy, remarkable for their vigorous growth and beautiful foliage. Flowers sessile, crowded, spicate; corolla tubular, one-lipped; lip three lobed. To attain perfection they require a deep soil, and a situation fully exposed to the sun. They will, however, thrive moderately well in common soil and partial shade. The habit being generally a bold one, they are most suited for isolated tufts, backgrounds of mixed borders, and the wild garden. Propagated by seeds, sown in gentle heat, or by division of the roots, in autumn or early spring.

> A. carduifolius (thistle-leaved). fl. blue. August. h. 3ft. Cape of Good Hope, 1816. Greenhouse species.

ACER, (from acer, hard or sharp; wood is extremely hard, and was formerly much used for making pikes and lances). Maple. ORD. Sapindaceæ. A genus comprised, for the most part, of handsome hardy deciduous shrubs, or trees, adapted for forming shrubberies, plantations, &c. Flowers greenish, except where mentioned. A. Pseudo-platanus is one of our most useful forest trees. Several of the species produce very useful timber; sugar is one of the constituent parts of the sap of all of them, and is obtained in large quantities from A. saccharinum, in North America. They all prefer a somewhat sheltered position. The most satisfactory soil is one free, deep, loamy, and well drained; the latter is especially desirable with some of the Japanese varieties. The varieties of A. japonicum, and palmatum are well worth growing in pots for conservatory decoration. Propagation: By seeds, sown either in autumn or spring, covering them not more than a ¼in. deep; the common varieties may be sown outside, while the rarer ones should be sown in a frame. By layers, and by grafting; the latter method is adopted with many of the rarer species and varieties, especially the variegated kinds; they are also readily increased by budding in summer.

FIG. 15. BOUQUET OF VARIOUS ACHIMENES.

To be successfully cultivated, they must be started and grown in stove heat till they commence flowering, when they may be removed to the conservatory or greenhouse, there to remain till after flowering. Batches of tubercles should be started in heat from February till the end of April, so as to give a succession of blossom. Shake each variety out of the old compost and insert separately in light, sandy soil; water sparingly at first, but when active they may receive more frequent supplies. When the shoots are about 2in. high, the tubercles may be transplanted to the pots, pans, or baskets in which it is intended to grow them, using as potting compost fibrous peat and leaf-soil in equal proportions, with about a sixth part of sheep's or rotten cow manure, and sufficient silver sand to make the whole porous and of a whitish appearance. Thorough drainage is indispensable, and a layer of the rougher soil, or sphagnum, should be placed over the potsherds, to prevent the loose soil stopping the drainage. Place the pans as near the glass as possible, and shade from bright sunshine. Give liberal supplies of water, with occasional doses of liquid manure; and, as the shoots lengthen, they may be pinched, to induce sturdy growth and a larger number of flowering branches. Place neat stakes to each stem, and keep well tied, arranging the stakes as symmetrically as possible, so as to ensure an even outline, but do not allow them to be seen. Light syringing with clear water, morning and evening, is beneficial. After the plants have done flowering, they should gradually have less water as the foliage and stems decay; a light airy situation is needed to mature and ripen the tubers. When the tops are quite dead, they may be removed, and the pots stored on the sides in any warm dry corner where[13] the temperature will not fall below 50deg., keeping the plants quite dry until the time of starting again. Achimenes are liable to attacks of thrips, red-spider, and green-fly, especially if the atmosphere is kept dry; these are easily destroyed by fumigation with tobacco. This must only be done when the foliage is quite dry, otherwise the plants will suffer. Achimenes are especially beautiful when well arranged, especially if two or three varieties are mixed together, as white, red, and purple (Fig. 15). There are several methods of increasing these:—(1) By cuttings; these need not be cut off at a joint, as they will root from any portion of the stem. Insert them thickly in well-drained pots of sandy soil—say a mixture of equal parts of peat and sand—and place in bottom heat. (2) By leaves, which should be severed from the stems, and pricked in pots of similar soil to the cuttings, placing all the petiole below the surface; stand the pots in bottom heat. (3) By scales from the corms, which should be carefully rubbed off and sown, like seeds, in pots or pans of the same compost, barely covered with sand, and placed in bottom heat. (4) By seeds, which are very small, and, consequently, require to be carefully sown. The pans must be thoroughly drained and filled nearly to the rim, levelled, and well watered with a fine rose, after which the seed should be thinly scattered, covered very lightly with sand, and placed in a shady position. Keep nicely moist, and apply water very lightly, or the tiny germs will be disturbed. Place a sheet of glass over the seed-pans. When the seedlings are large enough to handle, they may be pricked off and afterwards treated like rooted cuttings. The best time for all modes of propagating is early spring.

ACINETA (from akineta, immovable; the lip being jointless). ORD. Orchideæ. A small genus of cool house, robust, sub-terrestrial orchids allied to Peristeria. Flowers sub-globose, fleshy, arranged on stout, pendulous racemes. Leaves lanceolate, membranous, ribbed. Pseudo-bulbs angular, about as large as hens' eggs. The compost should consist of equal parts of fibrous peat and living sphagnum. In planting, first place a somewhat thick layer of the moss all round the inside of the basket, and press the soil firmly round the plant. During the growing season, the baskets should be taken down twice or three times a week and dipped into a tub of water, so that the whole may become saturated. In addition, the plants should be sprinkled with the syringe morning and evening, for they delight in an abundant supply of water and plenty of shade. When the growth is finished, they must be kept very dry, an occasional syringing, to keep the leaves from shrivelling, being all that is necessary.

> A. Arcei (Arce's). fl. yellow. Central America, 1866.

> A. Barkeri (Barker's).* fl. yellow and dark crimson, on stout scapes, produced from the base of the bulbs, and bearing fifteen to thirty fragrant flowers. Midsummer. l. broadly lanceolate, 2ft. long. Pseudo-bulbs 5in. to 7in. long. Mexico, 1837. SYN. Peristeria Barkeri.

ACIS (named after Acis, shepherd of Sicily, son of Faunus and the nymph Simæthis). ORD. Amaryllidaceæ. A genus of very pretty dwarf bulbous plants, suitable for the rockery, in sunny sheltered situations. This genus was formerly included with Leucojum, from which it is distinguished by its dwarf slender habit, filiform style, and membranous capsule. All are delicate little plants, with narrow linear leaves and bell-shaped flowers. They require a free, open, rich soil, and should remain and bloom undisturbed for years; divide the clumps every three or four years, and renew the soil.

ACISANTHERA (from akis, a point, and anthera, an anther; anthers jointed). ORD. Melastomaceæ. A monotypic stove genus allied to Rhexia, of semi-shrubby habit. It grows well in a mixture of loam, sand, and peat; and cuttings root freely in the same soil in stove temperature.

> A. quadrata (square-branched). fl. purple, ventricose, alternate, axillary, solitary. July. l. three-nerved, ovate, crenated; branches square. Habit erect, branched at the apex. h. 1ft. to 1½ft. Jamaica, 1804. More curious than ornamental.

ACMADENIA (from akme, a point, and aden, a gland; in allusion to the anthers being terminated by pointed glands). ORD. Rutaceæ. A small genus of beautiful greenhouse shrubs. Flowers terminal, solitary, or few, furnished with imbricate sepal-like bracts; petals five, with long claws, which are bearded on the inside. Leaves imbricate, linear-oblong, or roundish. They thrive best in a mixture of peat and sand, with a little turfy loam; thorough drainage is also necessary. Young cuttings pricked in a pot of very sandy soil, covered with a bell glass, and shaded, will root freely in a cool house.

ACONITUM (from Aconæ, or Acone, a harbour of Heraclea, in Bithynia, near where it is said to abound). Aconite; Monk's Hood; Wolf's Bane. ORD. Ranunculaceæ. An extensive genus of very ornamental hardy perennials. Flowers in terminal racemes; sepals five, the upper one helmet shaped, the two sides broader than the two back ones; petals five, small, the two upper with long claws hooded at the tip; the three inferior smaller or undeveloped. Leaves palmate. They thrive well in any ordinary garden soil. If left undisturbed for several years, they will attain a goodly size, and produce fine panicles of handsome flowers. They are invaluable for growing beneath the shade of trees, where they succeed better than almost any other class of plants. All are very easily propagated by divisions of the roots and seeds; the latter should be sown as soon as ripe in a cold frame. Care should be taken not to leave pieces of the roots about, for, with but one exception, those of all the species are very poisonous. Although very unlike horse-radish, they have frequently been mistaken for it, with fatal results; and none of the species should be cultivated in or near the kitchen garden.

Chiefly greenhouse evergreen shrubs, or trailers, from South America, with lanceolate stipulas, abruptly pinnate leaves, ending in a bristle; axillary one-flowered pedicels, or the flowers racemosely disposed at the tops of the branches, in consequence of the upper leaves being abortive. They will grow well in a mixture of loam, peat, and sand. Propagated by cuttings placed in sand, covered by a hand glass, in a gentle heat; or by seeds, which are generally more satisfactory. The annual species—A. muricata, A. papposa, and A. pendula—are not worth growing. The following are fairly representative of the most ornamental species.

Sori marginal, varying in shape from globose to linear, usually numerous and distinct, sometimes confluent and continuous. Involucre the same shape as the sorus, formed of the reflexed margin of the fronds, bearing the capsules on its upper side. None of the Adiantums are truly hardy except the American A. pedatum; even our own native species requires protection. The chief requirements of this handsome genus of ferns are good drainage, and a compost of fibrous peat, loam and sand.

Flowers with four spongy, cohering petals. A warm, good soil is most suitable; sow seeds about May in a shady spot. It is a biennial, but in favourable spots is self-sowing, and thus may be treated as a perennial. If placed either against a wall or in the open it is a pretty subject for trailing over a shrub or twiggy branch. From its fragile character, it can only be seen to the best advantage under glass.

ÆCHMEA (from aichme, a point; in reference to the rigid points on the calyces, or flower-envelopes). Including Pironneaua. ORD. Bromeliaceæ. Very handsome stove plants. Flowers scapose, panicled; perianth six-cleft, three outer segments sepaloid, longer than the three inner or petaloid ones. Leaves ligulate or sword-shaped, sometimes with marginal spines. The species thrive best in a well-drained compost of rich fibrous loam and leaf mould. They like plenty of light, which may be afforded by standing them on inverted pots, so as to raise their heads well up above the surrounding plants. Propagation: When the flower-spikes, which are sent up from the heart or crown of the plant, die away, suckers or offsets are produced near the base, and from these other flowers appear the year after. If large plants are desired, these suckers should be left to grow and spread around; but to produce single plants, the suckers must be taken off and potted singly, in sharp soil, and then stood where they can get a moist heat till rooted. To enable them to do this it is necessary to strip off a few of the lower leaves, and trim the bottom with a sharp knife, in order that it may heal over and callus more readily than it otherwise would. When rooted, the plants may be shifted into larger-sized pots; but for single crowns 32-sized pots are large enough, as the plants, being epiphytal in their nature, do not require much soil or any great supply of water, except when growing freely or sending up their flower-spikes. In winter, they should be kept rather on the dry side, to induce partial rest; and an important point is to see that water is not allowed to lie for any length of time in the crown of the plant, as when that is the case it is likely to cause them to rot.

AERATION. The exposure of the soil to the free action of the air, as essential to the growth of plants.

AERIDES (from aer, the air; in reference to the power the species have of deriving their sustenance from the atmosphere). ORD. Orchideæ. An extensive genus of epiphytal orchids, confined to the tropics of the Old World, including many large and showy-flowered species. The majority of them are extremely handsome. The thick fleshy leaves are noteworthy for their characteristically distichous arrangement—that is to say, they are arranged in two opposite rows. They are usually truncate at the apex, and for the most part deeply channelled down the centre, but in some species terete or nearly cylindrical. All of them throw out large fleshy roots from various parts of their stems, by which they absorb the moisture from the atmosphere; and, in order to grow them successfully, they must be fixed upon blocks of wood. But this method should be adopted only whilst the plants are young, as it is almost an impossibility for the cultivator to maintain a sufficient amount of atmospheric moisture to meet their requirements; and, unless this is managed, the leaves will shrivel and fall off, leaving only a few at the extremity. Therefore, as soon as the plants are established upon the blocks of wood, let them be removed and potted. Fill the pot three parts full of broken potsherds and lumps of charcoal, and then use nothing, but clean, living sphagnum, placing a few roots in the moss and leaving the others free. By this means a greater amount of moisture can be supplied to them, and thus beautiful and symmetrical specimens obtained. The Aerides are easily grown into handsome plants, which usually bloom profusely, and thus recommend themselves to all who cultivate orchids. From early spring until the end of September they should be treated liberally with water, at the same time taking care never to wet the flowers. After the above-named time, a gradual diminution in the water supply to the roots should take place; and the atmosphere, too, should be less densely charged with moisture. But drought should never be carried far enough to cause the leaves to shrivel, for, if this is done, the uniformity of the specimen is marred; and, although we are quite willing to admit the possibility of the plants producing a greater quantity of flower spikes after a thorough shrivelling, we prefer to advocate the system that gives a fair amount of flower coupled with good leafage. As before remarked, the Aerides are peculiarly eastern, and therefore are usually classed amongst the orchids which require the hottest houses. This is, in one sense, correct; yet they do not require the great amount of heat which many imagine, and which has, until recently, been given them. They must not, therefore, be excluded from the amateur's collection of orchids. During the winter season many of the species may be kept in a temperature of 58deg. to 60deg.; whilst during the growing season the temperature may run up by sun heat without limit, so long as a free circulation of air and a sufficiency of moisture are secured. The following status of temperature may be observed: In spring, from 65deg. in the night, to 70deg. or 80deg. by day; in summer, from 70deg. in the night, to 80deg. or 85deg. through the day; in winter, about 60deg. night, and 65deg. day.

> A. affine (related).* fl. delicate rose, produced, in great profusion, on branching spikes, which are sometimes 2ft. in length, and continue in bloom two or three weeks; the sepals and petals equal, rounded at the apex; the lip is sharply rhomboid and three-lobed, with a short spur. l. light green, about 1ft. long. h. 3ft.

> A. crassifolium (thick-leaved).* This is a dwarf, densely-habited plant, with broad, thick, purple-dotted obliquely-bilobed leaves. The flowers, which are borne on long and drooping spikes, are bare—larger than those of A. falcatum, which they resemble in form, and have the segments tipped with rich purple or amethyst, the centre or throat of the flower being ivory-white. Compared with A. falcatum, the spur is here bent under at an angle, while in that plant it is straight; the side laciniæ of the lip are much broader and shorter in the present plant, and the two keels on the lip here stand close together at the base, and become divergent, whilst in falcatum they are distant at the base, and become convergent near the middle of the lip. This species is described as being the best in the genus. It may be grown near the glass, suspended in a basket. Burmah, 1877.

A genus of very beautiful twining, radicant or parasitical stove shrubs, with opposite, simple, entire leaves, and axillary, terminal, few flowered, umbellate peduncles. They possess all the qualifications worthy of extensive cultivation—handsome flowers, fine deep green leaves, an agreeable fragrance, and are easily grown on blocks, which must be covered with green moss, fastened on with small copper wire. Preparatory to fastening them on, the roots should be covered with moss, and the plants secured to the block also by wire. After this, but little attention is requisite, except duly syringing and occasionally dipping in tepid water. As pot plants they are very beautiful, and in this method perfection is only obtained by growing them on fast and strong by generous treatment, which consists in frequently repotting in light rich compost till they are large enough to be trained up a trellis, formed of slender rods of willow or hazel. Propagated by seeds and cuttings. The former are very unsatisfactory; the latter root readily during spring in a well-drained pot, filled with a light compost, and having a surface of pure white sand, about 1in. deep. The best are obtained from half-ripened wood, cut into 2in. or 3in. lengths, and all leaves, with the exception of one or two at the top, removed. The cuttings should then be covered over with a bell glass, and placed in moderate bottom heat. So soon as rooted, transfer them singly to small pots, and again place under hand glasses, until they are thoroughly established, then gradually harden off. When about twelve months old, place the plants in their permanent quarters. Baskets are commonly and very effectively employed. Line these with moss, and fill with a light rich compost; place the plant as near the centre as possible, and, to promote a uniform growth, fasten down the branches with small neat pegs, at equal distances. During the summer, give copious supplies of water, to produce a liberal growth, which is of the utmost importance the first season, when they should not be permitted to flower. The following winter they should be kept cool and rather dry, thus giving them a rest. The year following, if properly managed, they will bloom profusely.

ÆSCHYNOMENE (from aischuno, to be ashamed; in reference to the leaves of some of the species falling on the slightest touch, like those of the Sensitive plant).[34] ORD. Leguminosæ. Stove herbs and shrubs, with impari-pinnate leaves, having many pairs of leaflets, and axillary racemes of usually yellow flowers. They thrive well in a good rich loam. Propagated by cuttings, placed in sand under a bell glass, in a brisk heat. Seeds of the herbaceous species require a good heat to start them into growth. The annuals are not worth growing. There are about forty other species known besides those mentioned, some of which may prove worthy of cultivation when introduced.

> Æ. aristata (awned). A synonym of Pictatia aristata.

> Æ. aspera (rough-stemmed). fl. yellow; racemes compound; peduncles, bracteas, calyces, and corollas, hispid. June. l. with thirty to forty pairs of linear leaflets, which (as well as the legumes) are smooth. Stem herbaceous, erect. h. 6ft. to 8ft. East Indies, 1759. Perennial.

> Æ. sensitiva (sensitive).* fl. white; legumes and racemes glabrous; peduncles branched, few-flowered. June. l. with sixteen to twenty pairs of linear leaflets. Stem smooth. h. 3ft. to 6ft. Jamaica, 1733. This shrub requires a sandy soil.

ÆSCULUS (a name given by Pliny to a kind of oak having an edible fruit; derived from esca, nourishment). The Horse Chestnut. ORD. Sapindaceæ. A genus of hardy showy trees, well adapted for lawns or parks, having a beautiful appearance when in flower. They will do well in any soil, but the more loamy the better. Increased by layers, put down in the spring, or by grafting or budding on the common horse chestnut. Seeds, where procurable, should be sown singly in rows in spring, where they may remain until they are of sufficient size to be permanently planted out. This genus is distinguished from Pavia, in having its capsules echinated, i.e., covered with prickles, like a hedgehog; but this character is not always consistent.

> Æ. carnea (flesh-coloured). Synonymous with Æ. rubicunda.

> Æ. glabra (smooth-leaved).* fl. greenish yellow; corolla of four spreading petals, with their claws about the length of the calyx; stamens longer than the corolla. June. l. with five leaflets, very smooth; foliage larger than the common species. h. 20ft. North America, 1821. SYNS. A. ohioensis, A. pallida.

> Æ. Hippocastanum (Common Horse-Chestnut). fl. white, tinged with red, on very handsome terminal racemes, which are produced in great profusion; petals five. April and May. l. with seven obovately-cuneated, acute, toothed leaflets. Asia, 1629. This, the common horse chestnut, is well known by the beautiful parabolic form in which it grows, and during the period of its flowering no tree possesses greater beauty. It has two or three unimportant varieties, differing in the variation of their leaves, and one also with double flowers. These are increased by grafting only.

> Æ. ohioensis (Ohio). A synonym of A. glabra.

> Æ. pallida (pale-flowered). A synonym of A. glabra.

> Æ. rubicunda (red-flowered).* fl. scarlet, in very fine terminal racemes; petals four, having the claws shorter than the calyx; stamens eight. June. l. with five to seven obovately-cuneated, acute, unequally serrated leaflets. h. 20ft. North America, 1820. This is a very distinct and beautiful tree when in flower, and does not attain so large a size as Æ. Hippocastanum. SYN. Æ. carnea.

ÆSTIVATION. The manner of the folding of the calyx and corolla in the flower bud.

ÆTHIONEMA (from aitho, to scorch, and nema, a filament; apparently in allusion to some tawny or burnt appearance in the stamens). ORD. Cruciferæ. A genus of elegant little plants, distinguished from allied genera in having the four larger stamens winged, and with a tooth. Herbs or sub-shrubs, perennial or annual, branched from the base, diffuse or erect. Flowers in crowded terminal racemes. Leaves fleshy, sessile. They are well worth cultivating in sunny situations, where they form a freer flowering habit than when growing in a wild state. Some of the more hardy species may be planted on rock work, which, by their dwarf growth, they are well adapted for. The annual and biennial species may either be sown on rockwork or in the front of the flower-border. A light dry soil suits them best. The shrubby kinds of this genus should be kept in pots, which should be well drained with potsherds, and treated like other alpine plants. Propagated by seeds, sown in May; or by cuttings, planted in summer.

> Æ. Buxbaumii (Bauxbaum's). fl. pale red; racemes crowded, aggregate. June. l. oblong-spathulate, glaucous. h. 6in. Thrace, 1823. A pretty annual, with erect branched stems. SYN. Thlaspi arabicum.

FIG. 37. ÆTHIONEMA CORIDIFOLIUM, showing Habit and Flowers.

> Æ. coridifolium (Coris-leaved).* fl. rosy lilac, small, in terminal dense rounded racemes. June. l. linear, glaucous, crowded. Asia Minor, 1871. A pretty perennial, shrubby below, with erect stems 6in. to 8in. high. See Fig. 37.

> Æ. gracile (slender). fl. purplish; racemes crowded, terminal; when in fruit, loose. June. l. lanceolate, pointed. h. 8in. Branches and branchlets slender, elongated. Sandy hills in Carniola, 1820. Shrubby perennial.

FIG. 38. ÆTHIONEMA GRANDIFLORUM, showing Habit and Flowers.

> Æ. grandiflorum (large-flowered).* fl. of a warm shaded rose; racemes crowded, terminal, numerous. May to August. l. ovate-oblong, glaucous. Mount Lebanon, 1879. This perennial species forms a spreading bush about 1½ft. high, and is perhaps the handsomest of the genus. It succeeds well in the ordinary border, but is far better suited for the rockery. See Fig. 38.

> Æ. membranaceum (membranous-podded). fl. purplish, in terminal racemes. June. l. linear, distant, somewhat fleshy, strictly appressed. h. 3in. to 6in. Persia, 1828. A small shrub, with filiform branches.

> Æ. monospermum (one-seeded). fl. purple, largish, in terminal racemes. July. l. oval or obovate, blunt, coriaceous; pods one-celled, one-seeded. h. 3in. to 6in. Spain, 1778. A pretty little biennial, with hardish branches.

> Æ. pulchellum (pretty).* This is said to be a new species, but it much resembles Æ. coridifolium. It is scarcely in full cultivation yet, but it proves one of the hardiest as well as one of the most handsome kinds.

> Æ. saxatilis (rock).* fl. purplish; racemes loose, terminal. May and June. l. lanceolate, acutish. h. 8in. Spain, 1820. A pretty annual.

> A. africana (African).* fl. crimson, disposed in racemes; petals four (furnished with claws), upper one largest. June. Legume ligneus, many-celled; seeds black, with scarlet aril. l. abruptly pinnate. h. 30ft. Sierra Leone, 1821.

AGALMYLA (from agalma, an ornament; and hule, a wood; the species are great ornaments to the woods in which they grow wild). ORD. Gesneraceæ. A small but very handsome genus of climbing or radicant herbs, with simple alternate leaves and axillary fascicles of flowers, something like the blooms of a Gesnera. Corolla limb oblique, five-lobed, scarcely two-lipped. A. staminea, the most generally cultivated species, is best grown in a basket, planted in a compost of rough peat, a little leaf soil, fresh sphagnum moss, and nodules of charcoal. Give an abundance of moisture when growing, which should be lessened after flowering, and allow the plant to rest during winter. It may be planted out on rockwork in the stove. Half-ripened cuttings will root freely in heat under a glass. The temperature in summer should not be less than 75deg. by day, and 65deg. by night.

> A. longistyla (long-styled). fl. crimson. Java, 1873.

> A. staminea (long-stamened).* fl. scarlet, disposed in axillary fascicles; corolla tubular, incurved, with a dilated throat. Summer. l. alternate, oblong, acuminated, denticulated, nearly equal at the base, downy beneath, and on the edges. Stem and petioles hairy. h. 2ft. Java, 1846. Stove species.

AGANISIA (from aganos, desirable; in reference to the beauty of these neat little plants). ORD. Orchidaceæ. A small genus of epiphytal orchids, requiring to be grown upon a block of wood suspended from the rafters of the stove. A damp atmosphere, syringing the roots and leaves freely when in a growing state, and shade during very bright sunshine, are primary points to be observed in their cultivation. Increased by dividing the pseudo-bulbs just previous to starting into new growth.

> A. cœrulea (dark blue).* fl. peduncles axillary, few flowered. "The colour is the well known one of Vanda cœrulea. There are, however, darker blue blotches quasi-tesselated over the flower. The lip is veiled, and has two very small basilar teeth, and then a veiled middle lacinia, that is sacciform, bordered with most remarkable long bristles, and with a deep violet blotch on its middle part beneath. The white column has two cartilaginous quadrate arms close to the stigmatic hollow." l. cuneate, oblong, acuminate. Pseudo-bulbs distichous, depresso-ovoid. Brazil, 1876.

> A. fimbriata (fringed).* fl. white; lip blue. Demerara, 1874. This species has also a sacciform, fimbriate lip, but, when compared with the foregoing, its flowers, leaves, and bulbs are much smaller, and the lip is not slit up to the apex, but the sac is round.

> A. graminea (grass-leaved). A weedy looking species, of no garden value. Guiana, 1836.

> A. ionoptera (violet-winged). The flowers, not very much larger than those of the lily of the valley, are white, with violet petals, and violet tips and streaks on the sepals. Peru, 1871.

> A. pulchella (pretty).* fl. white, with a blotch of yellow in the centre of the lip; the spike is produced from the bottom of the bulb. h. 8in. Demerara, 1838. It blossoms at different times of the year, and lasts two or three weeks in perfection. This species is very rare and pretty, and is best grown in a pot, with peat, and good drainage; requires a liberal supply of water at the roots, and the hottest house.

AGANOSMA (from aganos, mild, and osme, a smell; scent of flowers). ORD. Apocynaceæ. A genus of showy stove or warm greenhouse shrubs, with opposite leaves and terminal corymbs of large funnel-shaped flowers, the coronet of which is cup-shaped or cylindrical, "having its parts so united that they appear only as lobes around the mouth of the cup." All the species mentioned are well worth cultivating. They thrive best in a mixture of loam, sand, and peat, in equal proportions. Propagated by cuttings in sand, under glass, and with bottom heat.

> A. acuminata (pointed-leaved).* fl. large, white, fragrant; petals linear, falcate, curled; panicles axillary, longer than the leaves, scattered. l. from oblong to broad-lanceolate, acuminated, glabrous. Sylhet. Shrubby climber.

> A. caryophyllata (clove scented).* fl. pale yellow, tinged with red, deliciously clove scented; corymbs terminal. October. l. oval, acutish at both ends, tomentose beneath as well as the branches. India, 1812. Shrubby twiner.

> A. cymosa (cymose-flowered).* fl. small, whitish, fragrant; calyx and corolla hoary outside; cymes terminal, shorter than the leaves. l. elliptic, acuminated. Sylhet. Shrub.

> A. elegans (elegant).* fl. small, purple; corolla downy outside, as well as the calyces, bracteas, and pedicels; sepals longer than the tube of the corolla; corymbs terminal, crowded. l. elliptic, short-acuminated, glabrous. India. Shrubby twiner.

> A. marginata (bordered).* fl. numerous, large, white, fragrant; petals linear, falcate; panicles terminal, loose, corymbose, glabrous. l. lanceolate, smooth. Sylhet. Shrubby climber.

> A. Roxburghii (Roxburgh's).* fl. pure white, large, fragrant; calyx and corolla hoary outside; petals triangular; corymbs terminal. October. l. ovate-cordate, acuminated; petioles and veins red, glabrous, pale beneath, and shining above. India, 1812. Shrubby twiner.

> A. Wallichii (Wallich's).* fl. white, fragrant; calyx and corolla downy outside; corymbs terminal. l. elliptic-acuminated, shining above and pale beneath, glabrous. India. This species differs from the last in the veins of the leaves being parallel, not longitudinal, from the base to the apex. Shrubby twiner.

AGAPANTHUS (from agape, love, and anthos, a flower). ORD. Liliaceæ. African Lily. A genus, with numerous varieties, of very handsome greenhouse or conservatory herbaceous plants. Flowers large, scapose; perianth tubular, tube short; stamens six, having the filaments somewhat declinate. Leaves linear or lorate, arching, radical. They are of easy culture, and thrive best in strong turfy loam, leaf mould, decomposed manure, and river sand. They may be grown in large pots or tubs outside, to be removed in autumn, and placed under the stage in the greenhouse, or where they will be protected from frost, and kept moderately dry. If planted and left outside, the crowns should be well covered with cocoa-nut fibre in winter. During the summer, and especially in dry weather, the plants can hardly be over watered. They thrive admirably on the margins of lakes or running streams, and few plants, alike in flower and foliage, are more effective. Clear manure water may be given previous to or when the plants are in flower, and, after flowering, gradually lessen the quantity of water, until they are stowed away for the winter. They increase very rapidly, by offsets, and, if necessary, the old plants may be divided in early spring, to any extent required. In the more southern parts of this country they are quite hardy.

FIG. 39. AGAPANTHUS UMBELLATUS.

> A. umbellatus (umbelled).* fl. bright blue; perianth funnel-shaped, regular, deeply six-parted; tube short; scape tall, naked, bearing a many-flowered umbel. Summer and autumn. l. numerous, radical, linear, somewhat fleshy. h. 2ft. to 3ft. Cape of Good Hope, 1692. See Fig. 39.

> [36]

> A. u. albidus (whitish).* fl. pure white, on large full-sized umbels, smaller than those of the species, but very showy. Cape of Good Hope. This requires carefully drying off during the winter.

> A. u. aureus (golden). A variety in which the leaves are marked longitudinally with yellow. 1882.

> A. u. flore-pleno (double-flowered).* Identical in all respects with the species, except that it has double flowers, which are therefore, much more lasting than the single ones. A very handsome variety.

> A. u. Leichtlinii (Leichtlin's).* fl., perianth deep bright hyacinthine blue, 1¼in. long; scape about 1½ft. long, with a more compact umbel than any other known form. June. l. similar in size to the species. Cape of Good Hope, 1878.

> A. u. maximus (larger).* fl. bright blue, in immense umbels. This is larger in all its parts than the type, and when well grown is truly a noble plant. There is also a white-flowered form of this variety, which is most desirable, being equally as large.

> A. u. minor (smaller).* This is smaller in all its parts, with narrow leaves, and slender scapes of deep blue flowers. A very elegant variety.

> A. u. Mooreanus (Moore's).* fl. dark blue. h. 1½ft. 1879. A new variety, with shorter, narrower, and more upright leaves than the species; it has a dwarf habit. Perfectly hardy.

> A. u. variegatus (variegated).* Where variegated-leaved plants are desired, few could be more useful than this; its leaves are almost entirely white, with a few green bands, but they are neither so broad nor so long as in the type. It is an excellent subject for the domestic garden.

AGAPETES (from agapetos, beloved; in reference to the showy character of the plants). ORD. Vacciniaceæ. A genus containing about eighteen species of warm greenhouse or stove evergreen shrubs. Flowers corymbose and racemose; corolla tubular. Leaves alternate, coriaceous. They are all worthy of cultivation, but only two or three species are grown in England. Peat, turfy loam, and sand, in equal parts, is the best compost for them; and young hardened cuttings will strike in sandy soil, under a hand glass, in stove temperature.

> A. buxifolia (box-leaved).* fl. bright red, about 1in. long, tubular, wax-like, disposed in corymbs. April. l. small, oval oblong, bright green, leathery; branches spreading, twiggy. h. 5ft. Bootan.

> A. variegata (variegated). fl. scarlet, about 1in. long, tubular, lateral, corymbose. l. on short petioles, lanceolate, acuminated, denticulated, attenuated at the base, veiny. Khasia, 1837.

AGARICUS (derived from Agaria, the name of a town in Sarmentosa). Mushroom. ORD. Fungi. The most extensive genus known. It, however, contains but one or two species of cultural value. The most important ones are the common field mushroom, A. campestris (Fig. 44), the Fairy Ring mushroom, A. pratensis, and A. vaginatus. Familiar species are the Parasol mushroom, A. procerus (Fig. 43); St. George's mushroom, A. gambosus (Fig. 42); and the deadly Fly Agaric, A. muscarius (Fig. 41). For practical purposes the majority of this genus are poisonous, and many virulently so. Great care must be exercised in experimenting with unknown species, even by experienced fungologists. See Mushroom.

AGASTACHYS (from agastos, admirable, and stachys, a spike). ORD. Proteaceæ. A greenhouse evergreen shrub, with four sepalled apetalous flowers, which are disposed in numerous spikes. It thrives in a compost of equal parts loam, sand, and peat. Cuttings of ripened wood will strike in sandy soil under a glass, in a cool house.

> A. odorata (fragrant).* fl. pale yellow, sweet scented, crowded; spikes 4in. to 5in. long. April. l. bluntly lanceolate, sub-sessile, thickish, about 2in. long. h. about 3ft. New Holland, 1826.

AGATHÆA (from agathos, excellent; in reference to the beauty of the flowers). ORD. Compositæ. Allied to Cineraria, and requiring the same greenhouse treatment. It makes a very pretty object for summer decoration in the flower garden. Young cuttings root freely, in a gentle heat, at all times; and the plant may be had in bloom all the year round.

> A. cœlestis (sky-blue).* fl.-heads blue; peduncle one-headed. June. l. opposite, ovate, naked. h. 1½ft. Cape of Good Hope, 1753. Herbaceous perennial. See Fig. 40.

A stove evergreen tree, of economic value only, having the fruit enclosed by the persistent calyx; thriving in peat and light rich loam. Of easy propagation by cuttings in sand, with a moderate bottom heat.

> A. aromaticum (aromatic). fl. white. l. stalked, alternate, obovate, obtuse, leathery, entire, smooth. h. 30ft. Madagascar, 1823.

AGATHOSMA (from agathos, pleasant, and osme, smell; the plants contained in this genus have a pleasant smell). SYNS. Bucco, Dichosma. ORD. Rutaceæ. Beautiful small heath-like greenhouse shrubs, from the Cape of Good Hope. Flowers in terminal heads, or umbels; petals five, divided, with long claws, and scattered, short, narrow leaves, usually with revolute edges. They are of easy culture, thriving best in a mixture of sand and peat, with the addition of a little turfy loam. Young cuttings will strike root freely in a pot of sand, under a bell glass, in a cool house. They require to be shaded somewhat in the summer. Winter temperature, 40deg. to 45deg. About forty-six species are known.

> A. acuminata (taper-pointed leaved).* fl. violet; calyces smooth, glandular, on terminal subcapitate heads. April. l. ovate, somewhat cordate, long acuminated, fringed, at length spreading. h. 1ft. to 2ft. 1812.

AGAVE (from agauos, admirable; referring to the stately form in which some of them flower). ORD. Amaryllidaceæ. Flower-scape tall, proceeding from the centre of the rosette of leaves; perianth funnel-shaped, six-parted. Leaves large, fleshy, tufted. Mr. B. S. Williams describes them as follows: "They are noble, massive-growing plants, and form magnificent ornaments in the greenhouse or conservatory; whilst, from their slow growth, they do not rapidly get too large, even for a small greenhouse. Indeed, some of the real gems of this genus are neat, compact-growing plants, seldom exceeding 2ft. in height. Besides being fine ornamental plants for indoor decoration, the larger growing kinds are unquestionably the finest objects for the embellishment of terrace-walks, or surmounting flights of steps in the open air during the summer season, and also for plunging in rockwork, or about any rustic nooks in the pleasure-grounds, as, in such situations, they are quite in keeping, and thrive admirably. As is well known, they attain maturity very slowly; but when this condition is reached, the plant sends up a flower spike, and, after perfecting this, dies." A. Sartorii, and a few others are, however, exceptional, and go on flowering year after year. It is certainly fallacious to suppose it takes them a hundred years to flower. Agaves succeed well potted in good loam and river sand, to which may be added a little peat and leaf mould for some of the smaller-growing kinds. The drainage should be good, as they enjoy a liberal supply of water during the summer season, but during winter considerably less will be required. They can be increased by suckers when these are to be obtained, and also by seeds, to secure the production of which, in the species that do not yield suckers, the flowers should be carefully impregnated. In the following descriptive list of species, only those of horticultural value are mentioned, some of which are still rare; and in describing them we have availed ourselves of Mr. J. G. Baker's excellent monograph, which appeared in the columns of the Gardener's Chronicle. Many are omitted, not from any deficiency in horticultural beauty, but because, in several instances, only one plant of a species is known to exist in cultivation, and such cannot, therefore, hope to become in general cultivation for many years hence.

AGERATUM (from a, not, and geras, old; in reference to the flowers being always clear). SYN. Cœlestina. ORD. Compositæ. This genus includes several American species, for the most part half-hardy annuals and biennials; or, if the seed is not allowed to ripen, they become perennials. Involucre cup-shaped, of many imbricated linear bracts; receptacle naked. Leaves opposite. A light rich soil is most suitable. Very easily increased by cuttings or seeds; if required true, the former is the only sure method of propagation. To grow large plants for greenhouse decoration, sow the seeds in January, in heat, in sandy soil, barely covering them. As soon as the young plants are large enough, prick them off into thumb pots, and keep in heat till they grow freely, then place them into a cooler house. Transfer into larger pots as soon as the others are full of roots, until they are finally shifted into 10in. or 12in. pots. When these are full of roots, the plants should be watered with liquid manure twice a week, and they soon flower well, making fine specimens. During hot weather especially, they should be well syringed with clear water daily, to keep down red spider. The plants required for bedding (for which purpose the dwarf garden varieties are mostly used) should be raised about the same time, kept in small pots, gradually hardened off, and planted out in the middle or end of June. Cuttings of all the varieties strike readily in heat, treated like most soft-wooded plants, and, when rooted, may be managed as recommended for the seedlings.

> A. Lasseauxii (Lasseaux's). fl.-heads rose-coloured, small, disposed in corymbose heads. Summer. l. lanceolate-elliptic. h. 1½ft. to 2ft. Monte Video, 1870. A much-branched plant, requiring greenhouse protection in winter, and suitable for planting out in summer.

> A. latifolium (broad-leaved). A synonym of Piqueria latifolia.

> A. mexicanum (Mexican).* The commonest and most useful species, with a profusion of lilac-blue flowers. h. 2ft. Mexico, 1822. When used for bedding purposes it may be pegged down like the Verbena, or be allowed to grow its full height. Several very dwarf varieties of it have originated under cultivation, which supersede the species for bedding, the best of which are:—CUPID,* rich blue, very dwarf and floriferous; IMPERIAL DWARF, about 9in. high, with porcelain blue flowers; LADY JANE, of the same colour, very free; QUEEN,* silvery grey, about 9in. high; SNOWFLAKE,* white, very free and showy; SWANLEY BLUE,* very deep blue, 6in. to 8in. high. There is also a white-flowered variety of Mexicanum, which is very showy; and a variegated form, sometimes grown for the sake of its pretty foliage.

Stove evergreen trees or shrubs having very small flowers, disposed in branched axillary panicles. Leaves alternate, trifoliate, or impari-pinnate. There are several species, but the undermentioned is the only one worth growing yet introduced. It thrives well in a mixture of turfy loam and peat. Young cuttings ripened at the base, and taken off at a joint, will root in sand under a hand glass, in heat.

Hardy evergreen perennials and annuals, with broadish leaves, and one-flowered peduncles. Of easy culture, and well adapted for borders. They will all grow freely in common garden soil. Increased by division of the roots, and seed. A. cœli-rosa, and A. flos-Jovis are, perhaps, species of Lychnis, but the generic name which we have adopted is the most common one. All the species of this genus are exceedingly pretty free-flowering plants, and both annuals and perennials are well worth growing.

> A. cœli-rosa (rose of Heaven).* fl. delicate rose, white, or bright purple, solitary, terminal. Summer. Levant, &c., 1713. An annual species about 1ft. high, not tomentose; should be grown in patches. Sow the seed in April.

AGROSTIS (from agros, a field; the Greek name for a kind of grass). Bent Grass. ORD. Gramineæ. Annual or perennial grasses. Panicle loose; spikelets compressed. Several of the species are very effective, and well worth growing; and the spikes are pretty objects, when dried, for[44] window vases, &c. They are of easy culture, in ordinary garden soil. Sow seeds during spring in the open border, in tufts, among ferns, &c., or in pots for decorative purposes.

> A. spica-venti (windward-spiked). fl. panicle large, silky looking, loosely spreading. England. Annual.

AGROTIS. See Pot-herb Moths and Turnip Moth.

AILANTUS (from ailanto, referring to its lofty growth). Tree of Heaven. ORD. Xanthoxylaceæ. Tall deciduous trees. The stove species will grow freely in a mixture of loam and peat; and the best way to increase these is by pieces of the roots, planted in a pot with their points above the ground, and placed in a hotbed, where they will soon make fine plants.

> A. excelsa (tall). fl. whitish green, disposed similar to the following. l. abruptly pinnate, 3ft. long, with ten to fourteen pairs of leaflets coarsely toothed at the base, without glands. h. 66ft. India, 1800. A stove tree.

August. l. impari-pinnate; leaflets coarsely toothed at the base with glands. (The leaves on vigorous young trees are sometimes 6ft. in length.) h. 60ft. China, 1751. This tree grows with great rapidity for the first ten or twelve years, in favourable situations, afterwards its growth is much slower. It is quite hardy, and thrives in almost any soil, though one that is light and somewhat humid, and a sheltered situation, suits it best. It is a very desirable tree for plantations, or to stand singly on lawns, and is easily increased by slips of the roots.

AINSLÆA (in honour of Dr. Whitelaw Ainslie, author of a work on Indian drugs). ORD. Compositæ. Herbaceous perennials, of recent introduction. Although, no doubt, both species will prove tolerably hardy, they should have slight protection during winter. They thrive in light rich soil. Propagated by divisions of the root.

> A. aptera (wingless). fl.-head purple, disposed in an elongated spike-like panicle. l. deeply cordate, sinuately toothed; petioles wingless, whence the name. Sikkim Himalayas, 1882.

AITONIA (in honour of W. Aiton, once Head Gardener at Kew). ORD. Meliaceæ. A small and rather interesting greenhouse evergreen shrub from the Cape of Good Hope, and thriving well in an equal mixture of sandy loam and peat. Young cuttings will root in sand, under a bell glass, with bottom heat. The cuttings must not be put in very close together, and the glass should be wiped frequently, as they are apt to damp off.

> A. capensis (Cape). fl. pink; petals four, shorter than the projecting stamens. July. h. 2ft. 1777.

AIZOON (from aei, always, and zoos, alive; tenacious of life). ORD. Portulacaceæ. Greenhouse annuals, biennials, or evergreen shrubs. Flowers apetalous; calyx five-cleft, coloured on the inner surface. The undermentioned species is the only one worth growing. It requires no shade, a dry atmosphere, and light sandy soil. Propagated by seeds and cuttings.

> A. sarmentosum (sarmentose). fl. greenish, sessile. Summer. l. opposite, linear-filiform, rather connate, glabrous; branches rather villous, three-flowered at the apex, the two lateral flowers are bracteated, and spring from the sides of the middle one. Sub-shrub, erect, diffuse, glabrous, branched. South Africa, 1862.

AJAVA SEED. See Ptychotis.

AJAX MAXIMUS. See Narcissus.

AJOWAN. See Ptychotis.

AJUGA (from a, not, and zugon, a yoke; in reference to the calyx being equal, not bilabiate). Bugle. ORD. Labiatæ. Hardy annual or perennial herbaceous plants, usually procumbent or ascending, sometimes stoloniferous. Whorls two or many flowered, dense, sometimes all axillary, when the floral leaves conform to those of the stem; sometimes the superior whorls are approximate into spikes, then the floral leaves are small, and of a different form from the stem ones. All the species are of easy cultivation in ordinary garden soil. Perennials increased by divisions, or by seeds sown in the open border, during spring or autumn. The seeds of annual kinds may be sown in the open border in spring, where they are intended to remain.

ALKANET. See Anchusa tinctoria.

ALLAMANDA (named in memory of Dr. Allamand, of Leyden, who first communicated seeds of this genus to Linnæus). ORD. Apocynaceæ. Elegant climbing evergreen stove plants. Peduncles terminal and many-flowered; corolla funnel-shaped, with a narrow tube, gamopetalous, large, inflated, five-cleft at the apex. Leaves verticillate. This genus differs from all others of the same order, in the figure of the corolla. Of comparatively easy culture. To obtain their beauty of foliage and flowers, the shoots should be tied to wires placed within 8in. or 9in. of the glass that forms the roof of the structure in which the plants are growing. Trained in this way, and the shoots allowed to ramble in a somewhat natural manner, the effect, when the plants are in flower, is grander and more pleasing in every respect than when the shoots are tied to a formal trellis, of whatever shape. When thoroughly established, they succeed admirably in a compost of three parts good fibry loam, and one part wood charcoal or coarse river sand, with some rotten cow manure added. When potting the plants, make the fresh compost firm round the old balls of soil, and do not fill the pots too full; leave room for plenty of water, as, when in active growth, they require a liberal daily supply. They must be pruned annually in January or February, cutting the previous year's shoots back to within a joint or two of the old wood. Allamandas should be exposed to the light as much as possible at all seasons of the year. In winter months they require but little water, but the drainage must always be perfect. They are remarkably free from insect attacks of any kind. It may be also observed that the temperature should never fall below 55deg. This genus is easily propagated by cuttings, which will root at any time of the year in a bottom heat of from 70deg. to 80deg. The usual time is, however, in spring, when the old plants are pruned back. Choose the tops of the shoots, retaining two or three joints to each cutting; place these in a compost of sand and peat or leaf mould in equal proportions, singly, in small pots. Press the soil firmly around each cutting, and, when all are inserted, give a good watering, and plunge the pots in the propagating bed. Attend to shading and watering, and in about three weeks' time they will have emitted roots, and started to grow at the tops. The pots should now be raised out of the plunging material, and placed upon the surface thereof, and there allowed to remain two or three weeks longer; when the young roots will have, by this time, filled the little pots, and a shift into the larger ones will be necessary. Return the plants to the propagating bed, but do not plunge them therein. As soon as it is certain that the roots have commenced growth in the fresh soil, pinch the point of each plant that is intended to be grown on a trellis. This will cause the remaining buds to push out fresh shoots; and these, as soon as they have made two joints or whorls of leaves each, should have their points pinched out also. By repotting the plants as often as they fill their pots with roots during the first season of their growth, and pinching the points out of the shoots twice or thrice in the same time, a good foundation will be formed, from which the future specimens will spring. In the case of plants intended to be trained up rafters or pillars, they should not have their points pinched out until they attain to the height where it is desirable they should have more than one shoot, and be repotted as recommended above, for the first year; but, after that, they will require to be repotted only once a year, and this should be done soon after the buds have started to grow afresh in the spring.

ALLOTMENT GARDENS. A system of assigning small portions of land to be cultivated by labourers after their ordinary day's work.

The following are the most important rules to be carried out; but, should occasion arise, other rules must be made to meet particular cases:—

1. Each Allotment should consist of a rood of land (=¼ acre) to be let yearly at a rent of not more than 10s.

2. The Allotment to be let for one year only, to be re-let to the same occupier, provided his character has been satisfactory during the preceding year.

3. The rent shall be considered due at Michaelmas. If it remains unpaid for one month after that date, the Allotment shall be forfeited.

4. The Allotment to be cultivated solely by spade husbandry, and the same crop shall not be planted on the same part two years in succession.

5. Separate Allotments shall be divided by a space not less than 18in.

6. Any occupier trespassing on his neighbour's Allotment, or in any way interfering or damaging the same, shall not be allowed to hold his Allotment after the expiration of the year.

ALNUS (from al, near, and lan, the bank of a river; general habitat of the genus). The Alder Tree. ORD. Betulaceæ. A genus of deciduous trees and shrubs. Flowers monœcious; barren ones in long drooping autumnal catkins, lasting through the winter; fertile ones, produced in spring, in oval catkins, resembling a fir-cone in shape, the fleshy scales of which become indurated and ligneous as they approach maturity. Leaves stalked, roundish, blunt. Propagated usually by seeds, which are gathered towards the end of October; they require to be well dried, in order that the cones do not become mouldy. The seeds are sprinkled lightly on the ground with the slightest possible covering. Towards the end of the year, the seedlings will be about 10in. high. They are then planted in rows 1½ft. apart, and 6in. from each other, where they may remain for two years, after which they can be placed out in the situations where they are intended to stand. Planting is best done in November or March; and, if it is designed to make a plantation of[50] Alder, the young trees should be put in holes, made with an ordinary garden spade, about 9in. deep, and about 4ft. apart. They are also increased, but rarely, by cuttings, by suckers, and by grafting.

> A. cordifolia (heart-shaped-leaved).* fl. greenish-brown. March and April, before the development of the leaves. l. heart-shaped, acuminate, dark green, and shining. h. 15ft. to 50ft. Calabria and Naples, 1820. A large, very distinct, and handsome round-headed tree. It grows rapidly in dry soil, and is one of the most interesting of ornamental trees.

> A. firma (firm).* l. oval lanceolate, acuminate, sharply serrated, many-nerved. Japan. One of the most distinct of all the Alders.

FIG. 60. ALNUS GLUTINOSA, showing Catkins and Fruit.

> A. glutinosa (sticky).* barren catkins long, large, and cylindrical, pendent, their footstalks branched. fertile catkins small, ovate, with deep red scales. Spring. l. roundish-cuneiform, obtuse lobed at the margin, and serrated, somewhat glutinous, downy in the axils of the nerves beneath. h. 50ft. to 60ft. Britain. The Alder affects moist and damp situations, and, as it grows quickly, it is a useful tree to plant in bare situations. It is valuable as a nurse to other trees by the sea-side. See Fig. 60.

> A. g. aurea (golden).* Foliage golden colour.

> A. g. incisa (incised).* Compact form, with leaves quite like those of common hawthorn. SYN. A. g. oxyacanthifolia.

> A. g. laciniata (cut).* l. oblong and pinnatifid, with the lobes acute. This has elegant drooping branches and fern-like leaves, and is one of the best.

> A. g. oxyacanthifolia (sharp-prickled). Synonymous with A. g. incisa.

> A. g. quercifolia (oak-leaved).* l. with a sinuate outline, like that of the common oak. A very distinct form. The variety imperialis (=asplenifolia) slightly differs in its more or less lobed or cut foliage; A. g. variegata is a variegated form.

> A. incana (hoary).* l. broadly oval or ovate, rounded at the base, sharply serrate, whitened, and mostly downy beneath. h. 8ft. to 20ft. North Temperate regions. This affects drier situations than our native A. glutinosa.

> A. viridis (green). fertile catkins slender stalked, clustered, ovoid. l. round oval or slightly heart-shaped, glutinous and smooth or softly downy beneath, serrate, with very sharp and closely set teeth. Mountainous regions of northern hemisphere.

ALOCASIA (from a, without, and Colocasia). Allied to Colocasia. ORD. Aroideæ. Stove plants of great beauty, often with large and handsomely variegated, usually peltate, leaves, and shortly petiolate glaucous spathes. They are not difficult to grow, with a strong moist heat, and an abundant supply of water to the roots. The soil should consist of fibrous peat, with a little light fibry loam, in large lumps; to this add a good proportion of sphagnum and lumps of charcoal, with plenty of silver sand. Keep the bulbs and soil raised well above the rim of the pots, and finish off with a surfacing of either sphagnum or cocoa-nut fibre. The latter will soon encourage new rootlets. Crock the pot quite two-thirds up with clean, broken potsherds. Water freely when in good growth, and give liquid manure once or twice a week through the growing season. Shade during bright sunshine in the spring and summer months. Increased by seeds and division of the stems or rhizome. Winter temperature, 60deg. to 65deg.; summer, 75deg. to 85deg. See also Caladium and Colocasia.

India, 1867. A very distinct and free growing species.

> A. Johnstoni (Johnston's).* l. semi-erect, arrow-shaped, peltate, the front lobe being about 12in. long, and the two back lobes 14in. long and divergent, olive-green, prettily variegated and strikingly veined with bright rosy red.

ALOE (from Alloeh, its Arabic name). Allied genera: Apicra, Haworthia, Pachidendron, Phylloma. Including Rhipodendron. ORD. Liliaceæ. This hitherto much confused genus, and its allies, have been completely revised by Mr. J. G. Baker (vide "Journal of the Linnean Society," vol. xxviii. pp. 152-182), to whose account we are indebted for many of the following particulars:—Plant with or without stems; shrubs or (rarely) trees; leaves thick, fleshy, frequently in a rosette; peduncles simple or racemed, endowed with few or many empty bracts. Flowers racemed; pedicels bracteated at base, solitary; perianth-tube straight or slightly recurved; segments elongated; stamens hypogynous, as long as the perianth, or longer. Mr. Baker describes over eighty species, many of which, for various and important reasons, have no claim upon our space. Natives of the Cape of Good Hope, except where otherwise stated. These very interesting and curious plants thrive well in a mixture of open loam and peat, together with a small quantity of well decomposed manure. If old brick rubbish, or any other similar material is mixed with the soil to ensure perfect and rapid drainage, so much the better. Water, especially during winter, must be carefully administered. They thrive in an ordinary greenhouse, and cannot have too much light at any time.

A genus of pretty evergreen shrubs closely allied to Nolana, but differing principally in having several ovaries from one to six-celled, whereas Nolana has five four-celled ovaries. Leaves fasciculate; stems woody. They require ordinary greenhouse treatment, in a peat and loam compost. Cuttings root freely in sandy loam, with a very gentle bottom heat, in about a fortnight.

> A. cœlestis (sky-blue).* fl. pale blue, very large, axillary, solitary; peduncle elongated. July. l. terete, fascicled; plant nearly glabrous. h. 2ft. Chili, 1843. This pretty species is an excellent one for growing out-of-doors during summer months.

A genus of very pretty little half-hardy shrubs, herbaceous perennials, or annuals, with axillary, sub-racemose flowers, which are resupinate, with a sub-rotate five-cleft limb. Leaves opposite, or ternately whorled. They will grow freely in light rich soil; and are readily increased by cuttings in August or March, which should be placed in sandy soil in gentle heat, or by seeds sown in March. The herbaceous species may be treated as outdoor summer annuals, and should be raised in a little heat, and planted out early in May.

ALOYSIA (in honour of Maria Louisa, mother of Ferdinand VII., King of Spain). Sweet-scented Verbena. ORD. Verbenaceæ. This genus is nearly allied to Verbena, which see for generic characters. A greenhouse deciduous shrub, with a very fine perfume and graceful habit. The most satisfactory plan of culture is to obtain well-grown thrifty young plants in spring, and grow them on for the season. As the wood ripens, give less water until they are at rest, when it must be nearly withheld. About the end of January, bring into the light and warmth, and water thoroughly. As soon as the plants break, cut back to three or four eyes; and when the young shoots are about an inch long, transfer into rich sandy soil, using pots a size or two smaller than those they were in before. When the pots are full of roots, transfer to those that are to hold the plants for the season. By this mode of culture, good plants are to be maintained for any length of time. Aloysias form excellent pillar subjects for either a cold greenhouse, or out-of-doors, in which latter situation they thrive remarkably well, but require thorough protection, with straw bands or mats, from November until March, and afterwards at night, until danger from severe frosts has passed. They require no summer training, their young growth being continually cut off for the many purposes of decoration to which they are applied, and to which they are so well adapted. They are easily increased by young cuttings in spring, which should be placed in sandy soil and gentle heat, when they will root in about three weeks.

> A. citriodora (lemon-scented).* fl. whitish or lilac, very small, in terminal panicles. August. l. pale green, lanceolate, agreeably scented, arranged in whorls of threes; branches slender. Chili, 1781. SYNS. Lippia citriodora, Verbena triphylla.

ALPINE GARDEN. A very interesting style of gardening, which succeeds best by imitating Nature as closely as possible. The situation may be an open or a sheltered one. In building a Rock or Alpine Garden, it should be so arranged that all aspects are secured—shady and sunny—fully or in degree only. Pockets and crevices of various sizes may be made, and filled with soil suitable for the subjects to be planted therein, each one having a direct connection with the bulk of the soil; and the constructing material should be arranged with a gentle fall, so that moisture drains towards rather than from the roots. Alpine plants, as a rule, flourish better on a properly constructed rockery than if placed in any other position, because thorough drainage is effected, and the long and fine roots can run down in the crevices, where the soil is cool and moist. Although most alpine plants are naturally exposed to the full action of sun and wind, they should be placed out in early autumn, or early spring, so as to become thoroughly established before the approach of scorching summer weather. Failing materials necessary for the construction of a rockery, many alpines are easily grown in the ordinary border, in a naturally or artificially well drained situation. Excavate to the depth of 18in., put in a layer of stones, broken bricks, &c., 6in. deep; fill up with rich fibrous loam and leaf mould, adding sufficient sand to keep the soil porous. When the desired subjects are firmly planted, cover the surface with small gravel or stone chippings, which, while allowing the rain to penetrate the soil, effectually checks evaporation, and keeps it moist and cool, as well as giving the appearance of rocky débris. The effect will be better if the surface is slightly undulated.

ALPINE ROSE. See Rhododendron ferrugineum.

ALPINIA (in honour of Prosper Alpinus, an Italian botanist). ORD. Zingiberaceæ. A rather large genus of stove herbaceous perennials, with considerable grace and beauty. Flowers disposed in terminal spikes. Leaves lanceolate, smooth, even, entire, sheathed at the base, and having transverse veins. Roots fleshy, branched, having much of the smell and taste of ginger. The soil can hardly be too rich for the successful culture of these plants. A mixture of equal parts loam, peat, leaf mould, or thoroughly rotted hotbed manure, freely mixed with sharp sand or fine charcoal dust, forms an excellent compost. During the growing season, a top dressing of rotten dung, and a frequent application of weak manure water, prove excellent stimulants. They grow rapidly and consume a great deal of food in the production of so much stem and so many leaves. Unless the former is vigorous and of considerable thickness, it will fail to be crowned with spikes of flower. Alpinias require a high temperature, a rich, light soil, abundance of water, and not a little space, to grow them well. Soon after flowering, the plants will assume the yellow leaf, when water may be gradually withheld; but no attempt should be made to dry them off too severely, even after the stems die down. Nor must they be stored when at rest in a low temperature; in fact, they require as much heat to preserve them in health when resting as at any other time. The best time to divide the plants is after the young shoots have made an inch of growth in spring.

FIG. 65. ALSOPHILA REBECCæ.

ALSTRÖMERIA (in honour of Baron Alströmer, a Swedish botanist and friend of Linnæus). ORD. Amaryllidaceæ. Tall handsome hardy or half-hardy tuberous rooted plants, with leafy stems and terminal umbels of richly-coloured flowers; perianth regular, six-parted, subcam[57]panulate; inner segments narrower, two of which are somewhat tubulose at the base; stamens included within, and inserted with perianth; stigma trifid. Leaves linear, lanceolate, or ovate, and resupinate, or inverted in position by the twisting of the petiole. Cultivation: Few plants need less attention to grow them successfully, either in pots or planted out. The best position for those kinds which succeed outside is a deep and dry, sloping, sheltered border, in a compost of two-parts peat and leaf soil, and one loam with some sharp sand. Water freely if severe drought sets in; a surface covering of common moss, or cut fern in winter, will prove an advantage. They are very effective in masses. Propagation: They may be increased by seed or root division. Sow the former when ripe, or in early spring, thinly in pans, pots, or boxes, and place in a cool house or frame, so that they will receive some fostering in their early stages. The seedlings should be pricked out singly, when large enough to handle, and grown on till well established under glass. A mixture of peat, leaf mould, and sandy loam, is the best compost in which to sow the seeds and grow the young plants. When sufficiently established, they may be placed in a warm sheltered spot outside, and about 1ft. apart. The fasciculated masses of fleshy roots are readily separated into as many pieces as there are crowns; this operation may be performed during September or October, or February and March; but it must be done carefully. Except for the sake of increase, the less they are disturbed the better. They are excellent subjects for pot culture (some can only be managed thus, unless planted out in a house), and may be potted as early in the autumn as possible, in 8in., 10in., or 12in. pots. Thorough drainage is essential; arrange the crocks carefully, and place a layer of thin turfy loam over them. A compost of equal parts turfy loam, leaf mold, and fibrous peat, with an abundance of sand, will suit them admirably. Water sparingly at first, but when root-action is fully resumed, they must never be allowed to get dry. Support the stems by staking when they require it, and just previous to flowering, top-dress with some rotten manure and leaf soil. Occasional syringings will be necessary to keep down red spider, especially if the atmosphere is very dry. As the plants finish flowering, and the leaves fade, gradually diminish the supply of water until the stems are quite down, when they may be placed somewhere out of the way, free from frost, for the winter, but not kept dry enough to make them shrivel. In repotting, as much of[58] the old soil as is practicable should be removed, without seriously disturbing the roots, and the plants shifted into larger or the same sized pots, according to their condition. Alströmerias were at one time much more largely grown than they are at present, and the genus was represented in nearly every garden.

FIG. 66. ALSTRöMERIA AURANTIACA, showing Habit and Flower.

ALTERNANTHERA (in allusion to the anthers being alternately barren). ORD. Amaranthaceæ. Well known ornamental-leaved half-hardy plants, with inconspicuous flowers in axillary heads. Some of the undermentioned species and varieties belong, technically speaking, to Telanthera, in which genus the five stamens are inseparate below, and alternate with as many sterile filaments. They are so universally known in gardening under the present generic name, that we have here included them for convenience' sake. Where Alternantheras are used in large quantities (and if they are to be used effectively, a considerable number must be provided), their economical propagation becomes a matter of importance. A good colour can only be secured by growing them in[59] some house or pit in the full light and warmth of the sun; for, unless so grown, green or badly coloured plants will be the result. The best and quickest way of producing this class of plants in large quantities, is to make up a special hotbed for them about the end of March or beginning of April. If a pit be used, it should be filled up within 6in. of the glass with leaves and manure, or any other material that will produce a steady bottom heat of 80deg. or 85deg., and will last for three weeks or so at that point; which, at this season, will be an easy matter. When the heat has become regular and steady, about 4in. or 5in. of light, rich, sandy soil should be placed all over the surface, adding, at the same time, a sprinkling of silver sand on the top, and pressing it moderately firm with a flat board. The cuttings may now be prepared and dibbled in, 1in. apart each way. If kept close, moist, and shaded from bright sunshine, in a few days they will be forming roots, and so soon as that takes place the shading should be discontinued, and the ventilation gradually increased until they are finally hardened off and planted out. If carefully lifted, and placed in trays or baskets, with a rhubarb leaf over them, they may be taken any distance, and planted without flagging; with this advantage—that the plants being in good colour, the beds are effective at once. April is early enough to commence striking them, and these will be fit to plant out by the middle of June. The several species quoted in various dictionaries hitherto are unknown in English gardens.

> A. amabilis (lovely).* l. elliptic, acuminate, greenish in some stages, with the principal ribs stained with red, but under free growth becoming almost entirely suffused with rose colour, mixed with orange, the midribs continuing to be of a deep red hue. Brazil, 1868.

ALTERNATE. Placed on opposite sides of an axis on a different line, as in alternate leaves.

ALTHÆA (from altheo, to cure; in reference to the medicinal qualities of some of the species). Marsh Mallow. ORD. Malvaceæ. Hardy biennials or perennials, closely allied to Malva. Outer calyx six to nine-cleft, inner one five-cleft. Most species belonging to this genus are worthy of cultivation, particularly in woods, coppices, and shrubberies; they will thrive in almost any kind of soil. They may be either increased by dividing the plants at the roots, or by seeds; the biennial species must be raised from seed every year, which may be sown in spring where they are intended to remain, or in pans placed in a cold frame, from which the young plants may be removed when large enough.

> A. cannabina (Hemp-leaved).* fl. rose-coloured; peduncles axillary, many-flowered, loose, longer than the leaves. June. l. pubescent, lower ones palmately-parted, upper ones three-parted; lobes narrow, and grossly toothed. h. 5ft. to 6ft. South France, 1597. Perennial.

ALUMINOUS. Pertaining to, or containing alum, or alumina; as Aluminous soils.

ALUM-ROOT. See Heuchera.

ALYSSUM (from a, not, and lyssa, rage; in reference to a fable that the plant allayed anger). Madwort. Including Psilonema, Ptilotrichum, Schivereckia. ORD. Cruciferæ. Annuals or dwarf, branching, shrubby perennials, often clothed with hoary, stellate hairs. Flowers small, cruciform, white or yellow. Leaves distant, or the radical ones tufted, usually entire. Several of the species are very much alike. They are excellent plants for the rockery, or for the front of borders, growing freely in common but well-drained garden soil. They may be increased by cuttings, by division of the roots, or by seed. The cuttings should be made from young shoots, 2in. to 3in. in length, inserted in sandy loam, early in the season, in a[60] shady place. Seed may be raised outside, or in a frame in pans in sandy soil, most of them germinating in two or three weeks.

> A. alpestre (alpine).* fl. yellow; raceme simple. June. l. obovate, hoary. Stem rather shrubby at the base, diffuse, greyish. h. 3in. South Europe, 1777. Perennial. A very neat little tufted species. A. argenteum (silvery), A. Bertolonii (Bertoloni's), and A. murale (wall), are larger growing species allied to the above, but of less cultural merit.

FIG. 70. ALYSSUM SAXATILE.

> A. a. obtusifolium (obtuse-leaved). fl. yellow, corymbose. June. l. obovate-spathulate, blunt, silvery on the under surface. h. 3in. Tauria, 1828. A rare alpine.

FIG. 71. ALYSSUM SAXATILE VARIEGATUM, showing Flower and Habit.

> A. atlanticum (Atlantic). fl. yellow; raceme simple. June. l. lanceolate, hoary, and pilose. Stems shrubby at the base, erect. h. 6in. to 1ft. S. Europe, 1820. A. Marschallianum is intermediate between A. alpestre and A. a. obtusifolium; but is seldom met with under cultivation.

> A. gemonense (German).* fl. yellow, in close corymbs. April to June. l. lanceolate, entire, greyish-velvety from stellate down. Stem shrubby at the base. h. 1ft. Italy, 1710. Closely allied to A. saxatile, but not so hardy; it is very desirable for rockeries.

> A. macrocarpum (large-fruited). fl. white, racemose. June. l. oblong, blunt, silvery. Stem shrubby, branched, somewhat spiny. h. 8in. South of France, 1828. A. spinosa (thorny), and A. halimifolia (purslane-leaved), are very like this species. A. dasycarpum (thick-fruited) is an annual with yellow flowers.

> A. maritimum. See Kœniga.

> A. montanum (mountain). fl. yellow, sweet-scented; raceme simple. May to July. l. somewhat hoary; lower ones obovate; upper ones oblong. Stems rather herbaceous, diffuse, pubescent. h. 2in. or 3in. Europe, 1713. A distinct and charming species for the rockery, forming compact tufts of slightly glaucous green. A. cuneifolium (wedge-leaved), A. diffusum (diffuse), and A. Wulfenianum (Wulfenius') come close to this species, the latter being the most desirable.

> A. olympicum (Olympian). fl. deep yellow, small, in roundish corymbose heads. Summer. l. spathulate, sessile, very small, greyish. h. 2in. to 3in. Northern Greece.

> A. orientale (Oriental).* fl. yellow, corymbose. May. l. lanceolate, repandly-toothed, waved, downy. Stems suffruticose at the base. h. 1ft. Crete, 1820. There is a variety with variegated leaves.

FIG. 72. FLOWER SPIKE OF AMARANTHUS CAUDATUS.

> A. s. variegatum (variegated).* A constant and prettily variegated form, which is even more handsome than the type. On the rockery it does well, as it requires a sunny, well drained, position. See Fig. 71.

> [61]

> A. serpyllifolium (Thyme-leaved).* fl. pale yellow, in simple racemes. April to June. l. very small, ¼in. to ½in. long, ovate, scabrous, hoary. h. 3in. to 4in. Branches spreading, sub-woody at the base. South Europe, 1822.

AMARANTHACEÆ. An extensive order of herbs or (rarely) shrubs, with opposite or alternate leaves, and inconspicuous apetalous flowers, which are spicately or capitately disposed. The majority of this order are weeds; well-known exceptions being many species of Amaranthus.

AMARANTH, GLOBE. See Gomphrena.

FIG. 73. FLOWER SPIKE OF AMARANTHUS HYPOCHONDRIACUS.

AMARANTHUS (from a, not, and maraino, to wither; in reference to the length of time some of the flowers retain their colour). ORD. Amaranthaceæ. Hardy or half-hardy annuals, with alternate entire leaves and small green or red flowers in large bracteate clustered spikes. Flowers polygamous, furnished with three bracts at the base of a three or five-lobed glabrous perianth. Stamens four or five. Of very easy culture; they thrive best in rich loamy soil, and are largely employed for sub-tropical and other bedding, for vases and conservatory decorations, being very ornamental. The seed should be sown in April in a hotbed, and the plants thinned out in the same situation when about ½in. high. About the end of May, they can be transplanted out of doors in their permanent situations. They are also very handsome when grown in pots. The young plants should be potted off early, and freely encouraged, allowing plenty of pot-room and moisture, and be kept near the glass, to bring out their brightest colouring. To develop their full beauty, plenty of room is required. There are about twelve species (indigenous to warm and tropical countries).

> A. bicolor (two-coloured). l. green, variously streaked with light yellow. h. 2ft. India, 1802. This species is rather delicate, and must have a warm sunny situation.

> A. b. ruber (red).* l. brilliant glistening scarlet, merging into a dark violet red, mixed with green. Hardier than the type.

> A. caudatus (caudate).* Love Lies Bleeding. fl. dark purplish, collected in numerous whorls, which are disposed in handsome drooping spikes. August. h. 2ft. to 3ft. India, 1596. A very common and vigorous growing hardy annual. There is a yellowish-flowered variety, which, though less ornamental, is an effective contrast. See Fig. 72.

> A. cruentus (dark bloody). Synonymous with A. hypochondriacus.

> A. Henderi (Hender's). l. lanceolate, undulated, intense rosy carmine, varying with orange buff, golden yellow, and olive green. h. 3ft. A garden hybrid, closely allied to A. salicifolius. Pyramidal habit.

> A. hypochondriacus (hypochondriac).* Prince's Feather. fl. deep crimson, on densely packed, erect spikes. July. l. purplish beneath. h. 4ft. to 5ft. Asiatic, 1684. SYN. A. cruentus. See Fig. 73.

> A. h. atropurpureus (dark purple).* An improved variety of above.

> A. melancholicus ruber (melancholy-red).* h. about 1ft. Japan. A compact growing variety, with large shaded crimson leaves. Largely used for bedding purposes.

> A. salicifolius (willow-leaved).* l. 7in. to 15in. long, willow-shaped, linear, and wavy, which, by their drooping outline, present a very elegant and effective appearance. When fully grown, the leaves are brilliantly banded and tipped with orange, carmine, and bronze. h. 3ft. Philippine Isles, 1871.

> A. s. Princess of Wales.* l. carmine, orange green, and bright yellow, beautifully blended. h. 3ft. A garden hybrid.

> A. sanguineus (bloody). fl. purple, disposed partly in small heads in the axils of the upper leaves, and partly in slender, flexible spikes, which form a more or less branching panicle. July. l. blood red. h. 3ft. Bahama, 1775.

FIG. 74. AMARANTHUS TRICOLOR.

> A. speciosus (showy).* fl. dark crimson purple, disposed in large erect spikes, forming a fine plumy panicle. July. l. suffused with a reddish tinge, which disappears at the time of flowering. h. 3ft. to 5ft. Nepaul, 1819.

> [62]

> A. s. aureus (golden). fl. of a fine brownish-golden hue. Very effective when grown in masses.

> A. tricolor (three-coloured).* l. of a fine, transparent, purplish-red or dark carmine from the base to the middle; a large spot of bright yellow occupies the greater part of the upper end of the leaf; point generally green; leafstalks yellow. h. 1½ft. East Indies, 1548. See Fig. 74. There are several garden varieties of this species, requiring a somewhat warmer situation.

AMARYLLIDEÆ. A large and important order of usually bulbous plants, sometimes with a stem. Flowers solitary, umbellate, or paniculate; perianth superior, six-lobed, often with a corona at the top of the tube. Leaves ensiform or linear. This order contains many very beautiful genera, including Agave, Amaryllis, Crinum, Hæmanthus, Hippeastrum, Narcissus, Pancratium, and several others.

AMARYLLIS (from Amaryllis, the name of a country-woman mentioned by Theocritus and Virgil). ORD. Amaryllideæ. Half-hardy or hardy, deciduous, bulbous plants. Flowers large, sweet-scented, pedicelled; spathe two-leaved; umbels few-flowered; perianth with a very short tube, funnel-shaped, six-parted, sub-regular or irregular; segments many-nerved, broad, undulate, spreading somewhat at the apices; stamens at the summit of the tube, unequal, declined; anthers fixed by the middle, incumbent, curved into a circular arch after bursting; style declined; stigma thickened, sub-three-lobed; scape tall, solid, compressed. Capsule obovate; seeds globose, fleshy. Leaves appearing at a different season from the scapes, numerous, strap-shaped. The following genera are sometimes arranged hereunder, but in this work are treated separately: Brunsvigia, Crinum, Hippeastrum, Nerine, Sprekelia, Sternbergia, Vallota, Zephyranthes. Warm, dry, and well-drained positions in front of hothouses, or at the base of south or south-west walls, are the most suitable sites for A. Belladonna and its varieties. The soil should be composed of good, fibrous loam, leaf mould, and sand, in equal parts. Insert the bulbs 6in. to 8in. deep, and surround with sand, after which they may be covered with the compost, which should be pressed firmly about them; they should not be again disturbed for years, when they will ultimately establish themselves, and produce grand masses of blossom. The best time to plant a fresh stock is June or July, when they commence root-action, before the flower-stems are sent up. In their growing season, and in dry weather, an occasional soaking of clear water, or liquid manure, will be greatly beneficial. The extremely ornamental plants now largely grown, and frequently classed as Amaryllis in nurserymen's catalogues, belong to the genus Hippeastrum. For pot-culture of the Belladonna Lily, see Hippeastrum.

FIG. 75. AMARYLLIS BELLADONNA,
showing Habit at
Flowering Season.

> A. Belladonna.* Belladonna Lily. This splendid species is very variable, both in the size and colour of the flowers, frequently producing variously-shaded flowers, from almost white to a reddish or purplish hue. Autumn. West Indies, 1712. See Fig. 75. The leaves and flowers are not produced together. In Fig. 76 they are both shown in the same illustration for economy of space.

> A. B. pallida (pale).* A pale-coloured variety. h. 2ft.

AMASONIA (named in honour of Thomas Amason, one of the earlier American travellers). SYN. Taligalea. ORD. Verbenaceæ. A genus comprising six species (which may be reduced to four) of stove sub-shrubs, natives of tropical America. Flowers yellow or sulphur-coloured, racemose or panicled; calyx five-cleft; corolla five-cleft, sub-bilabiate. Leaves alternate, toothed or rarely entire. For culture of the only species introduced, see Clerodendron.

> A. punicea (reddish-brown). fl. yellow, with pretty, brownish bracts; peduncles once or twice trifid, cymose or one-flowered. May and June. l. slender, 3in. to 2in. long, oblong- or elliptic-lanceolate, shortly acuminate, unequally toothed. Stem erect, simple or slightly branched. h. 2ft. to 3ft. Brazil, 1884.

AMATEUR. This term is usually meant to refer to one who has a taste for a particular pursuit, and who is, in a pecuniary point of view, independent of it. An Amateur gardener is one who rears and grows his plants, and cultivates his garden, for his own amusement—for mere love of horticulture.

FIG. 76. AMARYLLIS BELLADONNA, showing Bulb and Flower Spike.

AMBER, SWEET. See Hypericum Androsæmum.

AMBER-TREE. See Anthospermum.

AMBROSINIA (commemorative of Professor Giacinti Ambrosini, of Bologna). ORD. Aroideæ (Araceæ). A curious, half-hardy, tuberous perennial, thriving in any light soil, with protection in winter. Increased by seeds, and by divisions. The former should be sown, as soon as ripe, in a cool house; and the latter should be made just previous to new growth in spring.

[63]

> A. Bassii (Bass's).* fl., spathes prolonged into a long tail, and a tongue-shaped spadix, with the male flowers on one side, and so placed as to preclude the access of pollen to the stigma on the other side of the spathe, save by insect agency. l. oblong, stalked. h. 4in. Corsica, Sardinia, 1879.

AMBURY, or ANBURY. The name given to galls of small Weevils (Ceuthorhynchus sulcicollis) which appear on the roots of Cabbages and Turnips, as well as of the Wild Mustard, and of other weeds belonging to the genus Brassica. The galls form swellings individually about the size of split peas, but often two or more are joined to form considerable masses. In each is a space inclosing a white grub. Anbury is usually not very hurtful. It is quite distinct from Clubbing. The galled roots should be collected, before the grubs emerge, and burned.

AMELANCHIER (Savoy name of the Medlar, to which this genus is closely allied). TRIBE Pomaceæ of ORD. Rosaceæ. Hardy, deciduous shrubs or small trees, with racemes of white flowers, and simple, serrated leaves; bracteas linear-lanceolate. Pome, when mature, three to five-celled. They are of easy cultivation, in a somewhat rich, loamy soil, and are propagated by layers or cuttings, in autumn, in sheltered situations; by seeds, and by grafting, in early spring, on the Hawthorn or the Quince, or the weaker on the stronger-growing species.

> A. canadensis (Canadian).* Grape Pear. fl. white. April. Pome purple. l. oblong-elliptic, cuspidate, when young rather villous, but at length glabrous. h. 6ft. to 8ft. Canada, 1746. A very ornamental tree, having a profusion of flowers in early spring, and rich autumnal foliage. SYN. Pyrus Botryapium.

> A. c. florida (flowery).* fl. white, numerous, in upright racemes. May. Pome purple. l. oblong, obtuse at both ends, coarsely serrate in the terminal portion, glabrous in every state. h. 10ft. to 20ft. North America, 1826.

> A. c. ovalis (oval-leaved). fl. white; racemes pressed together. April. l. roundish-elliptic, acute when rather young, velvety beneath, glabrous when mature. h. 6ft. to 8ft. North America, 1800.

> A. c. parvifolia (small-leaved). This has a dwarfer habit, and shorter leaves, than the type.

> A. sanguinea, (bloody). fl. white; racemes capitate. April. Pome blackish-purple. l. oblong, rounded at both ends, sharply serrated, always naked. h. 4ft. to 8ft. North America, 1800. This form differs principally from A. canadensis in the fewer flowers, much shorter raceme, and shorter, broader, and more ovate petals.

AMERICAN BLIGHT, or WOOLLY APHIS (Schizoneura lanuginosa). The white, cottony-looking matter which is found upon the bark of the Apple and other trees of a similar nature, belongs to a species of Aphis, which has short legs: the females are wingless, while the males are winged; the latter appear in July and August. The insects belong to a group of Aphides unprovided with honey tubes on the hinder part of the body, and in which the third vein of the front wing shows only one fork The woolly coating also distinguishes them from true Aphides. The Blight is said to have been imported from America in 1787, but this is uncertain.

As these insects get into the cracks and under the bark of trees, they are hard to dislodge. The injury inflicted is not apparent for some time; but, in process of time, large, cankerous wounds are produced, which gradually (with the aid of the insects) destroy the branches, and render the tree useless. If young trees are attacked, they are rendered valueless in a very short time. The insects hide in crevices of the bark of the trees each autumn, and remain dormant during the winter, ascending to their old quarters as the weather becomes warm. Trees which are covered with moss and lichens probably serve as places for hybernation; hence, it is desirable to remove such hiding-places, as well as all pieces of dead bark. To their being left may be frequently attributed the severe attacks of Blight experienced where they exist on trees. So soon as the cottony substance makes its appearance, one of the following remedies should be applied, and, if persisted in for a few seasons, the trees will be quite cleared.

Brushing and Scraping. In winter, the trees should be thoroughly cleaned; and, so long as there is a chance of the insects being in the bark, all loose pieces, moss, &c., should be brushed off, and the parts affected should be thoroughly saturated with a strong solution of soft soap or of soft soap and lime-water, applied with a stiff brush, so as to enter all the crevices.

Gas Liquor. This is the ammoniacal liquor from gas works. It must be diluted with from eight to twelve times its bulk of water, or it is dangerous to the trees; in fact, after dilution, it is advisable to test it, previous to using to any great extent. As the woolly covering of the insects resists water, it is desirable that the liquor be applied with a brush, and forced amongst the Blight.

Infusion of Tobacco Leaves (½lb. to 1 gallon) kills the insects on shoots dipped into it.

Paraffin or Petroleum. This is a simple and useful remedy. Obtain a painter's half-worn sash-tool, free from paint, and just moisten it in the oil. Then brush out each infested place as often as the Blight appears, and in one season the trees will be cleared.

Spent Tan. Collect spent tan into a heap a month or two before it is to be used, and if it has heated well and rotted, so much the better. In winter, clear away all leaves, rubbish, grass, &c., and spread the tan at the rate of about thirty loads to the acre, taking care that it surrounds the base of each tree infested with Blight. Practical proof of its utility has been given.

Turpentine and other Spirits. The mode of applying these is the same as for paraffin, but they frequently injure the bark, and sometimes kill young trees.

To kill insects on the roots, it is well to clear away the soil as far as possible from them, and to saturate the place with soapsuds or ammoniacal solutions; soot, quicklime, or other applications to the soil would also prove useful.

Other remedies that have been suggested are the drainings of stables, and grafting-clay plastered over the bark.

A stove, evergreen tree of almost unsurpassed magnificence and brilliancy, requiring a very high and moist temperature. It delights in a rich, strong loam, and may be propagated by cuttings of the half-ripened wood, inserted in sand, under a glass in bottom heat of about 80deg.; also by seeds.

> A. nobilis (noble).* fl. of a fine vermilion colour, diversified with yellow spots, large; racemes long, pendulous, axillary. May. l. large, impari-pinnate, bearing six to eight pairs of leaflets. h. 30ft. to 40ft. India, 1837. The flowers are, unfortunately, somewhat ephemeral, lasting but a few days in perfection, during which period, however, no object in the whole range of the vegetable kingdom presents a more striking aspect than this tree.

AMICIA (commemorative of J. B. Amici, a celebrated French physician). ORD. Leguminosæ. A pretty, greenhouse or half-hardy perennial, succeeding in any warm, sheltered spot. Young cuttings will root in sand, under a hand glass, in heat.

AMMOBIUM (from ammos, sand, and bio, to live; in reference to the sandy soil in which it is found). ORD. Compositæ. This well-known everlasting is closely allied to Gnaphalium, from which it differs principally in habit. Receptacle with oblong, pointed, toothed, chaffy scales; involucre of imbricated leaflets. It may be treated as a half-hardy annual, or as a biennial, if seeds are sown in September and kept in a cool greenhouse during the winter, and this is the best way to grow it. Any moderately good soil suits it.

A handsome genus of hardy deciduous shrubs with very graceful impari-pinnate leaves, and many pairs of leaflets, which are full of pellucid dots. Racemes spicate, elongated, usually in fascicles at the tops of the branches; corolla without wings and keel; vexillum or standard ovate, concave. They are well adapted for small shrubberies, requiring a sheltered situation, and thrive well in common garden soil. Increased by layers, or cuttings, taken off at a joint, and planted in a sheltered situation early in autumn; these should be allowed to remain undisturbed till the following autumn. Amorphas produce an abundance of suckers, from which they may be readily propagated.

> A. canescens (hoary).* The Lead Plant. fl. dark blue. July. l., leaflets ovate-elliptic, mucronate. h. 3ft. Missouri, 1812. Whole plant clothed with hoary hairs.

> A. fruticosa (shrubby).* The False Indigo. fl. very dark bluish purple. June. l., leaflets elliptic-oblong; lower ones distant from the stem. h. 6ft. Carolina, 1724. Shrub glabrous, or a little villous. There are several varieties, having mucronate, emarginate, or narrower leaflets, but all with purple flowers. A host of names, representing the merest forms of A. fruticosa, are to be found in nurserymen's catalogues. Amongst them are: caroliniana, crocea, crocea-lanata, dealbata, fragrans, glabra, herbacea, nana, pubescens, &c. These differ so slightly from the type and from each other, that it is impossible to distinguish them.

AMORPHOPHALLUS (from amorphos, deformed, and phallos, a mace; alluding to the inflorescence). SYN. Pythion. Including Proteinophallus. ORD. Aroideæ (Araceæ). A very remarkable genus, closely allied to Arum, but distinguished therefrom by "their spreading, not convolute, spathes; by their anthers opening by pores, not by longitudinal slits; by the numerous cells to the ovary; and by the solitary, erect ovules, those of Arum being horizontal." A soil consisting of two-thirds good rich loam, with the additional third of sweet manure, thoroughly rotted, suits them well. Other essentials are plenty of pot room, a genial atmosphere, and a temperature ranging from 55deg. to 65deg., or even 70deg. They require to be kept dry, and warm in winter, as nothing is more fatal to them than cold or damp. Beneath a shelf or stage in the stove is an excellent spot for them, or they may be stored in sand, and kept free from frost. They are difficult to increase; the corms of most of them are of great size, and rarely make offsets. Efforts should consequently be made to induce the plants to seed whenever practicable. All the species are strikingly effective in sub-tropical bedding. For fertilising and growth of seedlings, see Arum.

> A. campanulatus (bell-shaped).* Similar to A. Rivieri, but the flowers are brown, red, and black, and the scape is neither so stout nor so tall. h. 2ft. India, 1817. SYN. Arum campanulatum.

> A. grandis (large). fl., spathe green, white inside; spadix purplish. h. 3ft. Java, 1865. Stove species.

> A. Lacourii (Lacour's).* l. pedatisect, the ultimate segments lanceolate, yellow-spotted; petioles transversely mottled with yellow markings. Cochin China, 1879. Greenhouse. The correct name of this species is Pseudodracontium Lacourii.

> A. nivosus. See Dracontium asperum.

> A. Rivieri (Rivier's).* fl., spadix, spathe, and scape, reaching 3ft. or more in height, appearing before the leaves; scape stout and strong, of a deep green colour, speckled or dotted with rose; spadix projecting, deep red; spathe of a rosy-green colour. March to May. l. solitary, decompound, 40in. to 50in. across, on tall marbled petioles. Cochin China. Perhaps the most useful species. SYN. Proteinophallus Rivieri. See Fig. 78.

FIG. 78. AMORPHOPHALLUS RIVIERI, Foliage and Inflorescence.

> A. Titanum (Titan's).* fl., spadix 5ft. high, black purple; spathe nearly 3ft. in diameter, campanulate in shape, with patent and deeply toothed edges. The deeper portion of the interior is pale greenish, but the limb is of a bright black purple hue; the outside is pale green, smooth in the lower portion, but thickly corrugated and crisp above; scape about 1½ft. long, green, marked with small whitish orbicular spots. l. the divided blade covers an area of 45ft. in circumference. West Sumatra, 1878. As will be seen from the above, this extraordinary plant is of gigantic proportions, and, in size of the flowers, eclipsing nearly all others in the vegetable kingdom. SYN. Conophallus Titanum.

AMORPHOUS. Without definite form.

AMPELOPSIS (from ampelos, a vine, and opsis, resemblance; resembling the Grape Vine in habit, and to which it is closely allied). SYN. Quinaria. ORD. Ampelideæ. A genus nearly allied to Vitis. Calyx slightly five toothed; petals concave, thick, expanding before they fall; disk none. Fast growing and ornamental climbing, hardy deciduous shrubs, of very easy culture in common garden soil. Cuttings, having a good eye, may be taken in September, and pricked either under handlights in sandy soil on the open border, or in pots stood on the stage or shelf in a greenhouse; they root readily, and will be fit for transplanting early in the spring. Or cuttings made from the young soft wood, expressly grown for the purpose, in spring, root freely in gentle heat. This applies especially to A. tricuspidata. They are also easily increased by layers. Most of the species will thrive with equal vigour in almost any position, however exposed.

> A. aconitifolia (Aconite-leaved).* l. palmisect, with pinnatifid segments. China, 1868. A slender and very elegant free-growing species, with long reddish branches. There are two or more varieties. SYNS. A. lucida, A. triloba, A. tripartita, and Vitis dissecta. See Fig. 79.

AMPHIBLEMMA CYMOSUM. See Melastoma corymbosum.

AMPHIBLESTRA. Included under Pteris (which see).

AMPHICARPÆA (from amphi, both, and karpos, a fruit; in allusion to the two kinds of pods—those of the upper flowers being scimitar-shaped, three or four-seeded; those of the lower, pear-shaped, fleshy, usually ripening but one seed; these lower pods bury themselves in the ground after fertilisation). ORD. Leguminosæ. A genus of ornamental annuals, with herbaceous, twining stems, and sometimes apetalous flowers, allied to Wistaria. The species are of easy culture. Seeds should be sown in the open border, in spring, in a sunny situation.

AMPHICOME (from amphi, on both sides, and kome, a head of hair; in reference to the seeds being furnished with a tuft of hairs at both ends). ORD. Bignoniaceæ. Flowers axillary or terminal. Leaves alternate, unequally pinnate. Very ornamental greenhouse or half-hardy rock herbaceous plants. If planted outside, they must be protected during the winter from wet and severe frosts. A mixture of loam, sand, and leaf soil suits them well. Increased by striking the young shoots in spring in sandy[67] soil in gentle heat; or by seed, which should be sown in early spring, in pots of sandy soil placed in a greenhouse.

> A. arguta (finely-cut).* fl. red, drooping; racemes axillary, terminal; corolla tubular near the base, ventricose above. August. l. alternate, impari-pinnate; leaflets opposite, on short petioles, three to four pairs, lanceolate, acuminated, deeply serrated. h. 3ft. Himalaya, 1837.

> A. Emodi (Emodian).* fl. rose and orange, erect; racemes axillary; corolla 1½in. to 2in. long, bell-shaped, slightly tubular below. August to October. l. impari-pinnate, with numerous leaflets. h. 1ft. to 1½ft. India, at high altitudes, 1852. A very beautiful plant.

AMPHILOPHIUM (from amphilophos, crested on all sides; limb of corolla much curled). SYN. Amphilobium. ORD. Bignoniaceæ. A handsome stove evergreen climber. Corolla somewhat coriaceous, with a short tube, and a large ventricose throat. Loam and peat, well mixed, suits it best; cuttings from young shoots root readily in sand, under a hand glass, with bottom heat, during the spring months.

> A. paniculatum (panicled).* fl. rose-coloured; panicle terminal, composed of three-flowered peduncles. June. l. joined by pairs, opposite; leaflets ovate-roundish, acuminated, sub-cordate. West Indies, 1738.

AMSONIA (in honour of Charles Amson, a scientific traveller in America). ORD. Apocynaceæ. Very pretty hardy, herbaceous perennials, with alternate leaves, and terminal panicles of pale blue flowers; corolla with linear lobes, and a narrow funnel-shaped tube. They thrive in half shady positions in borders, or the edges of shrubberies, where they will not need to be frequently transplanted. Propagated by cuttings during the summer months, or by divisions of the roots in spring.

> A. latifolia (broad-leaved). Synonymous with A. Tabernæmontana.

FIG. 82. AMSONIA SALICIFOLIA, showing Habit and Flower.

> A. salicifolia (willow-leaved).* fl. light blue, in terminal corymbose cymes; corolla small, funnel-shaped, with a rounded tube; throat whitish, bearded. Summer. l. lanceolate, smooth, acute. h. 1½ft. to 2½ft. North America, 1812. Habit less erect than the following species. See Fig. 82.

> A. Tabernæmontana (Tabernæmontanus).* fl. pale blue, in cymes; petals lanceolate, acute, slightly hairy on the outside; sepals also lanceolate, acute. Summer. l. ovate-lanceolate, acute, shortly stalked. h. 1½ft. to 2½ft. North America, 1759. SYNS. A. latifolia, Tabernæmontana Amsonia.

AMYGDALUS (from amysso, to lacerate; fissured channels in the stone of the fruit). Almond. ORD. Rosaceæ. TRIBE Drupaceæ. Well known, ornamental, deciduous spring flowering shrubs. Drupe clothed with velvety pubescence, with a fibrous dry rind, separating irregularly, having the stone of the fruit pitted or smooth. The larger-growing species are very excellent for shrubberies, or as specimen trees; being in blossom before most other trees, they make a fine appearance in early spring. The dwarfer kinds are also well fitted for small shrubberies or the fronts of large ones. For greenhouse culture they should be obtained in a small pyramidal shape; they are not, however, suited to a small house, as the plants, to bloom well and be effective, ought to be at least 2ft. or 3ft. high, and proportionately wide. Plenty of root room is essential. After potting, water thoroughly, and place the trees in an orchard house for a few weeks, when they may be removed to their permanent station. A temperature of about 50deg. or 55deg. is sufficient to hasten the flowering; a higher temperature is apt to frustrate the object in view. After flowering, gradually harden off the plants until about the end of May, when they may be plunged out of doors for the season. Repotting should be done as soon as the leaves fall. Increased by budding upon seedling plum-stocks in summer. The Almond is grown on the Continent for its fruit. See also Prunus.

AMYRIS (from a, intensive, and myron, balm; the whole of the trees in this genus smell strongly of balm or myrrh). ORD. Burseraceæ. Ornamental stove evergreen trees, abounding in a resinous fluid. Flowers white, disposed in panicles. Leaves unequally pinnate. They thrive well in a mixture of loam and peat; and cuttings root freely in sand, under a hand glass with bottom heat, during the spring months.

> A. balsamifera (balsam-bearing). Synonymous with A. toxifera.

> A. braziliensis (Brazilian).* fl. white; panicles axillary, shorter than the leaves. August. l. with one to three pairs of opposite leaflets; leaflets lanceolate, tapering to the base, rounded at the apex, mucronate, quite entire, veiny, shining above, discoloured beneath. h. 20ft. Brazil, 1823.

West Indies, 1818. The wood, known as Rhodes Wood, bears a fine polish, and has a pleasant smell. SYN. A. balsamifera.

ANACAMPSEROS (from anakampto, to cause return, and eros, love). SYN. Rulingia. ORD. Portulacaceæ. Very dwarf greenhouse succulent herbs or sub-shrubs, natives of the Cape of Good Hope. Flowers large, expanding only in the heat of the sun; petals five, very fugacious; sepals five, opposite, oblong, rather concrete at the base; pedicels one-flowered, short or elongated, disposed in racemes. Leaves ovate, fleshy. They grow freely in sandy loam, mixed with some lime rubbish; but little water is needed. Cuttings root freely if laid to dry a few days before planting. Leaves taken off close to the plants, and also left to dry for a short time before being planted, will take root. Seed, when obtainable, should be sown in the spring.

All are very pretty and free flowering plants, of easy culture. The annuals are raised from seed sown in a sunny spot in spring; the perennials are increased by striking cuttings of the young shoots, or division, at any time, either under a hand glass or in a close frame. Keep in the shade until well established, and gradually harden off. Plant outside in light rich soil for summer flowering, and each year secure a stock in frames during the winter. They require, if left out of doors, a protection during the winter, except A. tenella.

> A. fruticosa (shrubby).* fl. axillary, large, vermilion, with a dark throat. May to August. l. verticillate, four in each whorl. h. 2ft. Morocco, 1803. A biennial.

ANALOGY. Resembling a thing in form but not in function; or vice versâ. Corresponding with a thing in many points, but differing in more, or in points of more importance.

ANANAS (from nanas, the South American name for the Pine Apple). SYN. Ananassa. Pine Apple. ORD. Bromeliaceæ. Stove herbaceous perennials, having the berries collected with the bracts into a compound fruit. Leaves rigid; edges spiny. The variegated form is a useful plant for decorative purposes, and may be employed without the usual harmful consequences attending stove plants generally, but it must not be subjected to cold draughts. The soil should consist of two parts fibrous loam, one of peat, one of dung and leaf mould, and another of sand. Those propagated from suckers, which should be laid by a day or two and then inserted in a strong heat, have, as a rule, longer and lighter-coloured leaves. Offsets are often produced at the base of the fruit, and make stout plants, with high-coloured foliage. When the plants are potted in spring, plunge them in bottom heat, to hasten their growth; but this is not absolutely necessary. Should it be desired to fruit the variegated form, the plants may be submitted to the same process of culture as detailed under Pine Apple (which see).

> A. hirsutum (hairy). fl. whitish, a little larger than those of A. bellidifolium, of which it is, perhaps, only a downy variety. h. 1ft. to 2ft. Portugal, 1818. SYN. A. Duriminium.

FIG. 85. DRY FRUITING PLANT OF ANASTATICA HIEROCHUNTINA.

ANASTATICA (from anastasis, resurrection; plant recovering its original form, however dry it may be, on immersion in water). ORD. Cruciferæ. A very curious and interesting little annual, the leaves of which fall off from the plant after flowering, the branches and branchlets then become dry, hard, and ligneous, and rise upwards and bend inwards at their points. This plant has the remarkable property of resuming vitality on being placed in water, after being kept in a dry state for many years. Seeds should be sown in heat, in the spring, and the plants afterwards potted off and plunged again in heat to hasten their growth,[70] which cannot otherwise be fully developed with our precarious and sunless summers.

FIG. 86. ANASTATICA HIEROCHUNTINA.

Young cuttings root freely under a bell glass if planted in sand, and placed in a moderate heat.

> A. pyrifolia (pear-leaved). fl. whitish, veined with red at the base, in axillary fascicles; lower petal obovate. July. l. alternate, stalked, stipulate, ovate, acute, crenated. Brazil, 1826.

ANCHOMANES (name of doubtful origin). ORD. Aroideæ. A remarkable and beautiful stove tuberous-rooted perennial aroid, allied to Amorphophallus, and requiring somewhat similar treatment. As soon as the leaves die down, the plants should be repotted in rich sandy loam and leaf mould, with ample drainage. They will need scarce any water or attention until growth commences the following spring, when they must have an abundance of water, and a moist atmosphere. Summer temperature, 60deg. to 85deg.; winter, 55deg. to 60deg. Propagated by seeds and offsets.

> A. Hookeri (Hooker's).* fl., spathe pale purple, appearing before the leaf, much expanded; spadix whitish; scape prickly, shorter than the petiole. June. l., petiole slender, prickly, bearing on its summit the horizontal blade, about 3ft. in diameter; this is divided into three primary divisions, which are again cut up into several leaflets, the largest of these being toothed. h. 3ft. Fernando Po, 1832. There is a variety with a paler coloured spathe. SYN. Caladium petiolatum.

ANCHOVY PEAR. See Grias cauliflora.

FIG. 87. ANCHUSA CAPENSIS, showing Flower and Habit.

ANCHUSA (from anchousa, paint for the skin; use of some species). ORD. Boraginaceæ. Very pretty hardy annuals, biennials, or perennials. Flowers in scorpoid racemes; corolla funnel-shaped; throat closed by erect, obtuse processes; nuts four, one-celled, inversely conical, with a contraction towards the point, fixed to the bottom of the calyx, perforated and concave at the base. Of easy culture, in ordinary soils, and preferring a sunny situation. Propagated by seeds, which should be sown in early spring in pots of sandy soil, when most of them will germinate in three or four weeks, some less. The honey-bee is very partial to this genus.

ANDROCYMBIUM (from aner, a man, and cymbos, a cavity; the stamens are enclosed in a hollow formed by the folding of the limb of the petals). ORD. Liliaceæ. A peculiar greenhouse bulbous plant, requiring a light sandy soil, dry atmosphere, no shade, and a season of rest; during the latter period, scarcely any water is required. Propagated by seeds and offsets.

> A. punctatum (dotted). fl. whitish, few, in a dense sessile umbel, surrounded by about four spreading lanceolate, acuminate leaves, which are 5in. to 6in. long, ½in. to ¾in. broad above the base, channelled down the centre from base to tip. South Africa, 1874.

> A. Skinneri (Skinner's). fl. white. h. 1½ft. Guatemala, 1850. SYN. Billbergia Skinneri.

ANDROMEDA (named after the daughter of Cepheus, who was rescued from the sea monster by Perseus). ORD. Ericaceæ. A dwarf, hardy shrub, found in peaty bogs in the temperate and Arctic regions of the northern hemisphere. Sow seeds as soon as ripe in pots or pans, very thinly, in sandy peat soil, and place in a cool frame, giving plenty of air. Place the young plants out in spring. Layers, pegged carefully down during September, will generally take twelve months to make sufficient roots to allow[72] of their being separated, and thus become independent plants. For other species often included under this genus in catalogues, see Cassandra, Cassiope, Leucothoë, Lyonia, Oxydendrum, Pieris, and Zenobia.

> A. polifolia (Polium-leaved). Wild Rosemary. fl. pinky white, drooping, sometimes tipped with red; corolla ovate, furnished with ovate, rather leafy imbricated bracteas, terminal, umbellate. June. l. linear-lanceolate, mucronulate, with the margins more or less revolute, quite entire, glaucous beneath, with an elevated rib, and reticulated veins. h. 1ft. The numerous varieties of this very beautiful native shrub principally differ in the colouring of the flowers.

ANDROPOGON (from aner, a man, and pogon, a beard; tufts of hair on flowers). ORD. Gramineæ. A large genus of grasses with polygamous flowers. The majority of species are of no horticultural value; several, however, are very ornamental subjects, and thrive well in a rich, deep soil. Easily propagated by seeds or by division of the roots. The South European kinds succeed in the open air if planted in a warm dry border.

> A. citratum (Citrus-leaved). Synonymous with A. Schœnanthus.

> A. Schœnanthus. Lemon Grass. fl. in threes; spikes imbricate, conjugate, panicled. A handsome species, the leaves of which emit a very fragrant odour when bruised. h. 2ft. India, 1786. Stove species. SYN. A. citratum.

Other species worth growing are furcatus, halepensis, muricatus, pubescens, scoparius, squarrosus, and strictus.

ANDROSACE (from aner, a man, and sakos, buckler; in reference to the resemblance of the anther to an ancient buckler). Including Aretia. ORD. Primulaceæ. Dwarf annuals or perennials, entirely alpine, agreeing in most characters with Primula, but having the tube of the corolla narrowed at the mouth. An airy, well-drained, and partially sunny position is essential in their culture. They thrive well between fissures of rocks or stones with a rich sandy peat soil. Drought and a sour soil are alike fatal, and both will be greatly obviated if small pieces of sandstone are mixed with the soil. The woolly species are best arranged beneath a jutting ledge of the rockery, which will afford them protection from the hottest sunshine, and from excessive wet in winter; additional comfort will be provided from the latter ill if a piece of glass is placed over them during the autumn and winter months. They can also be well grown, and make charming little specimens, in pots, with rich sandy soil and thorough drainage. Sprinkle sand among the small rosettes of leaves. They are increased by divisions, cuttings, or seed; the latter should be sown as early as possible, and raised in a frame.

> A. aretioides (Aretia-like). Synonymous with A. obtusifolia.

> A. argentea (silvery).* fl. white, sessile, very numerous. June. l. densely imbricated, lanceolate, oblong, covered with short hairs, forming very pretty silvery-grey rosettes. h. about 2in. Switzerland, 1826. This requires a well drained, sunny fissure. SYN. A. imbricata.

> A. carnea (flesh-coloured).* fl. pink or rose, with a yellow eye, three to seven, on hairy stalked umbels. July. l. awl-shaped, smooth, acuminated, not forming rosettes. Stem somewhat elongated. h. 3in. or 4in. Switzerland, 1768. This forms charming little cushions if allowed to remain undisturbed; it is easily increased. SYNS. A. Lachenalii, A. puberula.

> A. c. eximia (select).* Larger and more robust than the typical species, and a more rapid grower. Forms compact tufts of dense rosettes, bearing heads of rosy-crimson yellow-eyed flowers, on stems 2in. or 3in. high. Auvergne Alps, 1871. It requires moist sunny ledges and fissures of rockwork in peat, loam, and sand.

> A. coronopifolia (buckhorn-leaved).* fl. pure white, on slender pedicels, umbellate on peduncles, about 6in. high. April to June. l. lanceolate, distantly serrated, smooth, in flattish rosettes. Russia, 1755. This is a charming little biennial, well worthy of a place on the rockery. A colony of it is extremely pretty; it seeds freely, and a batch of young plants almost invariably takes the place of the old ones. SYN. A. septentrionalis.

> A. glacialis (glacial). Synonymous with A. alpina.

> A. helvetica (Swiss).* fl. white, nearly sessile, with a yellow eye, larger than the little rosettes of leaves on the stalk from which they spring. May. l. lanceolate, obtuse, closely imbricated, small, ciliated. h. 1in., forming dense cushions. Switzerland, 1775. A rare little gem, requiring a partially shaded position, and very sandy soil. SYN. A. Aretia.

March. l. awl-shaped, sharply pointed, in tiny rosettes. h. 3in. Pyrenees, &c., 1879. Very like A. carnea, but more delicate, earlier, and more abundant flowering, with deeper green foliage. It suffers from exposure to the sun, and therefore requires a partially shady position. Should be propagated from seeds or cuttings, which latter strike freely. See Fig. 90.

> A. lanuginosa (woolly-leaved).* fl. delicate rose, with a small yellow eye, umbellate. June to October. l. nearly 1in. long, clothed with shiny silken hairs. h. 6in. to 9in. Himalaya, 1842. A very beautiful species, with spreading or trailing shoots, easily multiplied by cuttings or layers. It requires a warm sunny spot on the rockery, with a sandy peat soil. When planted so that its shoots drape the face of a rocky ledge, it is one of the most charming plants possible to grow.

> A. obtusifolia (blunt-leaved). fl. white or rose, with yellow eye; umbels five or six-flowered. Spring. l. lanceolate or rather spathulate, in rather large rosettes. Stems downy. h. 2in. to 6in.

An exceedingly pretty and diminutive little alpine plant, grown, according to Mr. Robinson, "to great perfection in fissures between large rocks, with, however, deep rifts of sandy peat and loam in them. It will also grow on a level exposed spot, but in such a position should be surrounded by half-buried stones."

> A. sarmentosa (trailing).* fl. bright rose, with a white eye, in umbels of ten to twenty, on an erect scape. May and June. l. very silvery, forming dense rosettes, whence spring a number of runners, bearing at their extremities other tufts, which should be pegged down and covered with soil, when they will root freely. Himalayas, 1876. It requires rich sandy loam, a sunny position, and to be wedged between pieces of sandstone. Cover the rosettes during winter with a sheet of glass. See Fig. 91.

> [73]

> A. septentrionalis (northern). Synonymous with A. coronopifolia.

> A. villosa (hairy).* fl. rose or blush, with a deeper coloured eye, and a honey-like perfume, umbellate. May. l. narrow, oblong, covered with soft white down, chiefly on the under surface, in compact tufts. h. 2in. to 4in. Pyrenees, &c., 1790.

ANEMIDICTYON. See Anemia.

ANEMONE (from anemos, wind; the greater part of the species grow in elevated places, much exposed to the wind). Wind Flower. ORD. Ranunculaceæ. An extensive genus of very ornamental hardy perennials. The generic characters of Anemone proper are: Involucre of three cut leaflets, distant from the flower; calyx of five to twenty petal-like sepals; petals absent. Of sub-genus Hepatica: Involucre of three entire leaflets, just under the flowers; calyx of six to nine petal-like sepals; petals absent. For botanical purposes, they are both now included under the one generic name of Anemone; but in gardens the Hepaticas are frequently regarded as a distinct genus. They delight in a rich sandy loam, but most will thrive in ordinary garden soil. Some are suitable for borders, while others thrive best on the rockery, most of them preferring a damp and partially shady position. For the numerous varieties of A. coronaria, both double and single flowered, the soil can hardly be too rich, and the position, though open, should be a sheltered one, and well drained. The tubers may be planted early in October, about 6in. apart, and 3in. deep, various colours being intermixed, when a splendid effect is produced in the following spring. After flowering, the tubers should be taken up—say in June—and spread out thinly, in a shady, airy situation, until they are dry, when they should be thoroughly cleaned, and, if necessary, divided, and finally stored away in a cool place, in pots or boxes of dry sand until the planting season. Anemones make admirable pot plants if placed in a compost of two parts turfy loam, and one of leaf mould or rotten hotbed or cow manure, with about a sixth part of sharp gritty sand; but, if so grown, they should be protected through severe weather, and brought into warmth as required. The herbaceous species are propagated by root divisions or root cuttings, or by seeds, in autumn or early spring; the seeds are better sown as soon as ripe in pans in a cold frame. Some, such as A. japonica, are freely increased by division; while others, such as A. narcissiflora, are very slow; and the tuberous rooted ones, by root division and seeds. The best and most rapid means of propagating the invaluable varieties of A. coronaria, and also of obtaining new ones, is by seed. A careful selection of flowers, and skilful hybridising, will produce results commensurate with the trouble incurred. So soon as the seed ripen, they should be gathered and sown at once in a warm sheltered situation outside, or in pans under glass, covering lightly with sandy soil, and keeping moist. They are somewhat difficult to sow on account of a mass of cotton-like down which adheres closely to them; they should be thoroughly separated therefrom by rubbing them in dry sand. Of course, if the seed are sown at different times, plants will be produced which will flower at different periods, and a succession of bloom may be had from April to November—indeed, nearly all the year.

> A. fulgens (shining).* fl. of a dazzling vermilion or scarlet, with a black central patch of stamens, about 2in. across; sepals obovate. May. Greece, South Europe, &c., 1865. A very beautiful variety, much more showy than A. hortensis (of which it is generally regarded as a variety), and a universal favourite. In "Hardy Perennials," Mr. Wood says of this splendid species: "It may be grown in pots for conservatory or indoor decoration. It needs no forcing for such purposes; a cold frame will prove sufficient to bring the flowers out in winter. Borders or the moist parts of rockwork are suitable for it; but perhaps it is seen to greatest advantage in irregular masses in the half shade of trees in front of a shrubbery; and, after all, it[76] is impossible to plant this flower wrong as regards effect. To grow it well, however, it must have a moist situation and good loam." See Fig. 94.

> A. Halleri (Haller's).* fl. purplish inside, large, erect; sepals six, oval-lanceolate. April. l. pinnate, very villous; segments three parted; lobes with lanceolate-linear, acuminated divisions. h. 6in. Switzerland, 1816. A sunny border or the rockery. SYN. Pulsatilla Halleri.

Upper Nepaul, 1829. This requires a warm sheltered position to stand the winter. Very near A. japonica alba, and probably the progenitor of it.

ANEMONOPSIS (from anemone, and opsis, resemblance; flowers like those of the Anemone). ORD. Ranunculaceæ. A handsome and remarkable hardy herbaceous perennial, not unlike Anemone japonica, but smaller. It thrives in any light soil. Propagated by seeds and divisions of the root-stock in spring.

> A. macrophylla (large-leaved).* fl. in loose racemes; sepals about nine, concave, the outer three purple, internally pale lilac; petals twelve, in many rows, one-third the length of the sepals, linear-oblong. July. l. large, biternate, coarsely toothed, glabrous. h. 2ft. to 3ft. Japan, 1869.

ANEMOPÆGMA (from anemos, the wind, and paigma, sport). ORD. Bignoniaceæ. A handsome stove climbing shrub. For culture, see Bignonia.

> A. racemosum (racemose).* fl. delicate buff coloured, in axillary racemes, large. September. Brazil, 1879. This beautiful and vigorous climber is, as yet, very rare in cultivation.

ANETHUM (from ano, upwards, and theo, to run; in reference to its quick growth). ORD. Umbelliferæ. A genus of erect glabrous annuals. Flowers yellow; involucre and involucels wanting. Leaves decompound, with linear-setaceous lobes. This genus is of no ornamental value, its most important species being the garden Dill (A. graveolens), which see for culture.

ANGELICA (in reference to the supposed angelic medicinal virtues of some species). ORD. Umbelliferæ. Perennial or biennial herbs. Flowers white; umbels terminal; involucra wanting or of few leaves; involucels of many leaves. Leaves bipinnate. The common Angelica (A. Archangelica) is the only species that calls for mention. It is a native biennial, and was at one time in much request for confectionery, and as a herb of supposed great medicinal value. Seed should be sown in September or March in ordinary soil, and the young plants thinned out to about 18in. apart.

ANGELICA TREE. See Aralia spinosa.

ANGELONIA (from angelon, the local name of A. salicariæfolia in South America). SYN. Schelveria. ORD. Scrophulariaceæ. Very pretty stove herbaceous perennials. Flowers axillary, racemose; corolla irregular, bilabiate; lower lip saccate at the base, trifid; upper one smaller, bifid. Leaves opposite. Stem and branches quadrangular. A mixture of light turfy loam, peat, leaf soil, and sand, is a good compost. Cuttings of young shoots in spring strike readily under a hand glass, or plunged in the propagating bed, giving plenty of air daily.

> A. salicariæfolia (Willow-leaved).* fl. blue, hairy, axillary, solitary, pedicellate, disposed in terminal racemes. August. l. sessile, lanceolate, acute, serrated towards the apex, finely pubescent on both surfaces. h. 1½ft. to 3ft. South America, 1818.

ANGIOPTERIS (from aggeion, a vessel, and pteris, a wing). Including Psilodochea. ORD. Filices. A genus of gigantic greenhouse ferns. Capsules eight to fifteen, opening by a slit down the side, sessile, very close but not concrete, arranged in linear-oblong or boat-shaped sori near the edge of the frond. These ferns require a very liberal supply of water, and plenty of room to fully expand. The most suitable compost is a mixture of strong loam and peat, with some sharp sand. Thorough drainage must be afforded.

> A. evecta (evectic). cau. erect, 2ft. to 6ft. high, 1½ft. to 2ft. thick, very fleshy. sti. swollen and articulated at the base, furnished with two large leathery persistent auricles. fronds 6ft. to 15ft. long, bi- or tripinnate; pinnæ 1ft. to 3ft. long, spreading, the lowest the largest; rachis swollen at the base; pinnules 4in. to 12in. long, ½in. to 1½in. broad, linear-oblong, sessile or shortly stalked, acuminate; edge entire or finely toothed. Tropics of Old World. This is the only clearly defined species; the others usually known as distinct species are but varieties of it, and its culture should not be attempted if plenty of room cannot be afforded it.

ANGOPHORA (from aggos, a vessel, and phero, to bear; in reference to the shape of the fruit). ORD. Myrtaceæ. Australian evergreen greenhouse ornamental trees or shrubs. Flowers corymbose; calyx five or six-cleft. Leaves large, opposite. A mixture of leaf soil, peat, and sand suits them well. Ripened cuttings will root in sandy soil under a hand glass in a cool house, in a few weeks.

> A. cordifolia (heart-leaved).* fl. yellowish, corymbose, large. May. l. sessile, ovate, cordate at the base, glabrous. h. 7ft. to 10ft. New Holland, 1789.

> A. lanceolata (lanceolate-leaved).* fl. white, corymbose. May. l. petiolate, lanceolate, acuminate, glabrous. h. 4ft. to 6ft. New Holland, 1816.

ANGRÆCUM (deduced from angurek, a Malayan name for air plants). ORD. Orchidaceæ. TRIBE Vandeæ. These are among the most beautiful of epiphytal orchids. One characteristic, both remarkable and peculiar, is the long, hollow, tail-like spur depending from the base of the lip. The flowers are produced on spikes from the axils of the leaves. The leaves are evergreen, and arranged in two rows, the one opposite to the other, and, in many kinds, being curved, give the plant a very graceful appearance. The fact of these plants producing their blooms during the winter—a period when flowers are generally scarce—considerably enhances their value. They usually continue six or eight weeks in perfection, or even more. The following table of night temperatures should be almost universally adhered to for all the species enumerated, except A. falcatum, which thrives best in a cool house. From November to February, 58deg. to 63deg.; March to May, September and October, 65deg.; June to August, 70deg. The day temperature should be 7deg. or 8deg. higher than that of the night. A compost of crocks, charcoal, and sphagnum is best. A layer of a few large crocks at the bottom of the pot or pan will be required; over these spread another layer of charcoal and smaller crocks, just enough to allow the roots to support the plant; so that the first pair of leaves will be, in large plants, about 4in. above the rim of the pot, or proportionately less in the case of small plants. When the plant is carefully adjusted in its proper position, and held there with one hand, the other hand should work in among the roots more crocks and charcoal, ceasing so to do when within 2in. of the rim; the remaining space must be occupied with fresh sphagnum, pressed firm (this is most essential) in a cone shape, which may be built up to within ½in. of the lower pair of leaves. Prior to potting, which ought to be done between February and April, water should be withheld for a short time; but give a good soaking immediately after the operation. In the process of repotting, clear the roots of the old moss, all rotten stems, and particles of decayed roots. If plants are potted as we have recommended, a thorough soaking once a week only, or if grown on blocks of wood, or in suspended baskets or pans, about twice weekly will be found sufficient. Excessive fumigation, drought, whether atmospherical[79] or at the roots, will cause the leaves to drop, and prevent any growth being made, in which case the plant ought to be lowered. If the stems have emitted but few roots, a ring of moss fastened round the stems, and kept constantly wet, will induce the plant to throw out additional roots, when the lowering may be proceeded with. To keep the plants free from insect pests, frequently sponge the foliage. Thrips generally prove very troublesome, and a moderate fumigation is needful, dislodging the insects that may be secreted low down in the centre of the plant, shortly before the operation, by dropping a little weak tobacco water or sulphur among them.

> A. arcuatum (curved).* fl. white; racemes from the axils of the two-year-old leaves, two or three being produced from a single growth, about 6in. long, arching. l. about 4in. long, and ¾in. broad.

ANGULAR. Having angles, or forming angles.

ANGULOA (commemorative of Angulo, a Spanish naturalist). ORD. Orchidaceæ. A small genus containing about six species. The flowers, which are large and beautiful, are borne singly on scapes from 12in. to 16in. high, several of which are produced from the ripened pseudo-bulbs of the preceding year's growth. Pseudo-bulbs from 5in. to 8in. high, as thick as a man's wrist, bearing two to three erect, broad, lanceolate leaves, 2ft. to 4ft. long. Temperature, summer, day (maximum), 70deg.; night (minimum), 60deg. Winter, day (maximum), 60deg.; night (minimum), 45deg. These are bold growing cool-house plants, best grown in rough fibrous peat, with good drainage. They delight in an abundant supply of water both to the roots and foliage when growing, and require to be kept in a somewhat dark or heavily-shaded place. During the season of rest, and until young shoots commence growth, they should be kept rather dry. They are propagated by dividing the pseudo-bulbs, just before they commence to grow. The flowering season is summer.

> A. Clowesii (Clowes's).* fl. fragrant; sepals and petals concave, clear golden yellow; lip pure white; whole conformation globular, or tulip-like. Columbia (at 5000ft. to 6000ft. elevation), 1842. This is the largest growing species, of which there are one or two rare varieties.

> A. eburnea (ivory-flowered).* fl., sepals and petals of the purest white; lip spotted with pink. New Grenada. In other respects similar to above, but is very rare.

> A. Ruckeri (Rucker's).* fl., sepals and petals yellow, with crimson spots; lip deep crimson. Columbia, 1845. Not so large a grower as either of the foregoing, but with same sized flowers.

Flowers monœcious; corolla joined to the calyx, ventricose, red, with a five-parted spreading border. Fruit somewhat tetragonal. Several species have been introduced from time to time, but they are rarely seen in our gardens. Some of them are handsome plants, and well worthy of cultivation.

ANHALONIUM. See Mammillaria.

ANIGOZANTHUS (from anoigo, to expand, and anthos, a flower; in reference to the branching expansion of the flower stalks). SYN. Schwægrichenia. ORD. Hæmodoraceæ. Greenhouse or half-hardy perennial herbs. Flowers large, racemose or corymbose; perianth tubular,[80] elongated, woolly. Leaves linear ensiform. The species thrive in a turfy compost of peat and loam, three parts of the former to one of the latter; the whole intermixed with sand to make it porous. In the growing season they must be kept well watered, and somewhat dry during their period of rest in winter. They are very easily propagated by dividing the roots in spring.

> A. coccineus (scarlet).* fl. scarlet; perianth swelling towards the summit, hairy, segments a little reflexed; disposed in dichotomously-forked panicles; pedicels rather long. June. l. lanceolate, deep green. Stem ciliated. h. 5ft. Swan River, 1837.

ANISOCHILUS (from anisos, unequal, and cheilos, a lip; in reference to the inequality of both lips of calyx and corolla). ORD. Labiatæ. A very ornamental genus of stove perennials or biennials. Whorls of flowers densely imbricate into oblong cylindrical spikes; corolla with an exserted, defracted tube, inflated throat, and bilabiate limb. They thrive in any light rich soil. Cuttings will root in a sandy soil under a bell glass, in heat; seeds may be sown in February in heat.

> A. carnosum (fleshy). fl. lilac; whorls densely imbricate into oblong cylindrical pedunculate spikes. June to September. l. petiolate, ovate-roundish, obtuse, crenated, cordate at the base, thick, fleshy, tomentose on both surfaces. Stem erect. h. 2ft. East Indies, 1788.

ANNUALS. All plants which spring from the seed, flower, and die within the course of a year. A number of things, however, which are not strictly of annual duration, but which are sown every year in preference to housing the roots before they are killed by late autumn or winter frosts, are generally classed, for the sake of convenience, under the head of Annuals. Hardy Annuals are those which require no artificial aid to enable them to develop, but grow and flower freely in the open air. These are[81] best sown in the spots where they are intended to remain during March and April, and care must subsequently be taken to keep the ground clear of weeds, and also to thin out the seedlings, allowing each sufficient room to develop and exhibit its true character. If allowed to remain too crowded, the plants, as a matter of course, suffer, and the size and number of the flowers and the general effect are considerably decreased. Successional sowings of a good many of the showy species will be found to prolong their flowering season. In well-kept establishments, where Annuals are duly appreciated, several sowings are made in pots at intervals of a few weeks. As the previously-sown clumps begin to get shabby, they are removed, and replaced by others which have still to flower. By this means a continual sheet of blossom can be maintained for a long time. It is much better to trust to plants grown in pots in order to carry out the plan just sketched, as these receive no check when placed in their new quarters; whilst transplanted clumps frequently fail, and many species do not transplant at all readily from an open border. In order to secure, in early spring, a fine show of such plants as several of the Silenes, Myosotis, Saponaria, and a number of others, it is best to sow the seeds in an open, sheltered border, about the end of July or beginning of August, taking care to keep a small reserve stock in a cold frame, in case very severe weather kills the unprotected plants. Half-hardy Annuals are those for which our climate is not sufficiently warm, or, rather, our summer is not, as a rule, either hot enough or long enough, to allow them to grow, flower well, and ripen seeds, if sown in the open air. Many of these are amongst the showiest of garden plants, so it is worth while to give them the shelter of a warm frame during their earlier stages, and gradually harden them off, planting out at the end of May or beginning of June, when danger resulting from severe weather is passed. After germination, the seedlings should have plenty of light and air, or a weak, spindly growth, and, as a consequence, poor flowers, will result. The most satisfactory method of watering very tiny seeds is to place a piece of fine muslin over the seed-pot, through which the water will be easily conveyed to the seeds, and thus prevent disturbance. Tender Annuals require the same treatment as the half-hardy ones, except that they need throughout their existence the protection of a glass structure. All, or nearly all, garden Annuals delight in full sunlight and plenty of air. In the open, these requirements, as a rule, obtain, but sometimes mistakes are made under glass by keeping the plants too close and over much shaded, as well as too great a distance from the glass.

ANNULAR. Having a ring-like form.

ANNULATE. With the appearance of rings.

ANŒCTOCHILUS (from anoiktos, open, and cheilos, a lip; in reference to the spreading apex of the lip). SYNS. Anecochilus, Chrysobaphus. ORD. Orchideæ. Stove terrestrial orchids, the radical leaves of which are the chief attraction, being amongst the most beautiful and delicate objects in the vegetable kingdom. The flowers, which should be pinched off so soon as they appear, are, as a rule, small and unattractive. Few of the species exceed 6in. in height, with leaves from 2in. to 6in. long, including the fleshy petioles. They require a good deal of attention. To one part of silver sand, thoroughly washed twice or three times, add two of sphagnum, which should also be well washed and picked over, when it should be chopped into minute particles, in order that it may freely amalgamate with the sand; mix a little loam and peat with the whole. In the pots, when well drained by first placing a large piece of potsherd over the bottom and nearly half filling up with pieces broken small and of uniform size, place a thin layer of crude sphagnum, afterwards filling firmly with the mixture above mentioned, and bringing it up more or less in the form of a cone above the rim of the pot, into which the plants should be firmly fixed. Plants which have been propagated by division should be carefully transferred to 32-sized pots. About five separate pieces might be placed evenly over the surface. Make holes with a neat dibble, and into these drop the roots their entire length, pressing the soil firmly with the dibble. Fix them so that they may grow inwardly, and not out over the rim of the pots, pegging each creeping root needing such attention firmly down upon the surface of the soil afterwards; after a good soaking, they may be replaced in any warm, shady situation. For propagating, a strong plant is necessary; it may be cut into pieces just below the first joint, each piece having a root. The bottom piece should have two eyes—one to root from, and the other to push into a shoot. The "bottom," or plant which has been cut, should be replaced in its pot, and then put under a bell glass. It will soon throw up a young shoot; this ought to be left on until well rooted, when it may be separated and treated similarly to the portion first removed, still leaving the old part in the pot. These plants must be grown in glass cases, or under bell glasses, but they should always have a little air, for, as Mr. Williams says, when too much confined, they grow up spindly, and damp off in the stem; the latter, being fleshy, requires more substance and sturdiness. Air should be admitted through a space of about 1in. or 2in. The following ranges of temperature are advised: Winter, night, 55deg. to 60deg.; day, 65deg. to 70deg. during March, April, and May; night, 60deg. to 70deg.; and, afterwards, a few degrees higher, with a maximum day temperature of 80deg. Bottom heat should not be given, as it induces a weak, fast growth. Great care will be needed to prevent ravages of insects. The most suitable month for repotting is March, just before growth commences, when the plants will need plenty of water up to October, excepting when it is desirous to utilise them as drawing-room ornaments, in which case they should be kept rather dry for a short time previous. See also Dossinia, Goodyera, Hæmeria, Macodes, Physurus, and Zeuxine.

ANOMATHECA (from anomos, singular, and theca, a capsule, or seed-pod). ORD. Irideæ. Very pretty little bulbous perennials. Perianth hypocrateriform; tube triquetrous, constricted at the throat. The species are hardy when planted in warm sunny situations in the open border. Their dwarf stature, brilliance, profusion of flowers, and habit of blossoming continuously over a long period, render them very popular subjects amongst growers of hardy perennials. Although generally credited with being hardy, when cultivated out of doors they should be lifted and stored in frost-proof quarters before winter commences, until the following March. They are excellent as window garden plants, and also for pot culture. If grown in pots, they should be shaken out, and repotted in February or March. They multiply very rapidly, and may be divided in patches, not by single bulbs, once yearly. Light sandy loam, mixed with a little leaf mould, is the best compost. Anomathecas are sometimes increased by seed, which may be sown so soon as ripe, very thinly, in seed pans. Thin out the seedlings if growing very close together; the next season they may be put out four or five in a pot. When they become crowded, shift into a much larger pot, but do not disturb the ball. The young seedlings will probably produce flowers the second season.

> A. cruenta (bloody).* fl. rich carmine-crimson; perianth segments elliptical, three lower ones broader than the others, with a dark blotch at the base; tube long, whitish; scapes secund, bearing about five or six flowers. Summer and autumn. l. two-ranked, about ½in. broad, sword-shape, somewhat tapering. Bulb ovate, rather large. h. 6in. to 12in. Cape of Good Hope, 1830.

> A. juncea (rushy). fl. very bright pink, with a dark spot at the base, produced in profusion. The leaves are narrower than those of the foregoing. Cape of Good Hope, 1791. A rare species.

ANONA (Anona is the name applied to these plants in St. Domingo). Custard Apple. ORD. Anonaceæ. Stove evergreen shrubs, with fragrant leaves. Petals six, in two rows. Carpels indefinite, joined into one fleshy, many-celled, edible, roundish fruit, with a muricated, scaly, or reticulated skin. Anonas thrive best in rich loamy soil, mixed with a little peat. Ripened cuttings, with leaves intact, will root if inserted in sand and placed under a hand glass, in a moist heat. When seeds are procurable, they should be sown in pots, and plunged into a hotbed.

> A. Cherimolia (The Cherimoyer). fl. outer petals somewhat concave, linear-oblong, brown on the outside, each marked with a dark spot at the base; peduncles opposite the leaves, solitary. July. fr. somewhat globose and scaly, dark purple; esteemed by the Peruvians as one of their most delicate, and as being not inferior to any fruit in the world. l. ovate-lanceolate, not dotted; under surface silky tomentose, strong scented. h. 20ft. Peru, 1739.

> A. glabra (smooth-fruited).* fl. outer petals ovate, obtuse, brown; calyx leathery, large; peduncles opposite the leaves, two-flowered. July. fr. greenish-yellow, conoid, blunt, smooth. l. ovate-lanceolate, smooth. h. 10ft. West Indies, 1774.

> A. longifolia (long-leaved). fl. purplish; outer petals concave, thick, all acute, large, axillary, solitary, stalked. May. fr. ovate-globose, dotted, and reticulated, flesh-coloured. l. oblong, acuminated, mucronate, smooth. h. 20ft. Guiana, 1820.

> A. reticulata (netted). The Custard Apple, or Bullock's Heart. fl. outer petals oblong-lanceolate, acute, somewhat concave at the base, brownish on the outside, whitish-yellow on the inside, marked with dark purple spots. fr. ovate-globose, reticulate, as large as a tennis ball, with yellowish soft flesh; it is much esteemed by some people. l. oblong-lanceolate, acute, smooth, somewhat dotted. h. 15ft. to 25ft. Brazil, 1690.

> A. squamosa (scaly). Sweet Sop. fl., outer petals linear-oblong, somewhat concave at the base, nearly closing, greenish-yellow. fr. egg-shaped, scaly. l. oblong, bluntish, smooth, full of pellucid dots, rather glaucous beneath. h. 20ft. South America, 1739.

ANOPTERUS (from ano, upwards, and pteron, a wing; in reference to the seeds, which are winged at the apex). ORD. Saxifrageæ. A very handsome greenhouse evergreen shrub, having a free branching habit, large dark shining green leaves, and long panicles of salver-shaped flowers. It would probably prove quite hardy in the south and west of England, and parts of Scotland, provided it had a slight winter protection. It grows well in sandy loam and peat. When grown in pots, it requires plenty of room and water. Half-ripened cuttings root freely under a bell glass in a cool house or frame in summer.

> A. glandulosa (glandular).* fl. white, rose tinted, large; racemes erect, simple, terminal. April, May. l. alternate, rarely nearly opposite, ovate-oblong, attenuated at both ends, nearly sessile, leathery, toothed. h. 3ft. Van Diemen's Land, 1823.

ANSELLIA (named after Mr. Ansell, the botanical collector who accompanied the ill-fated Niger Expedition). ORD. Orchidaceæ. Strong growing, free flowering stove epiphytal orchids. Best grown in large pots, as they produce a quantity of roots. They require a compost of turfy peat, with moderate drainage. An ample supply of water during the growing season is needed; but care must be taken not to let any remain in the heart of the plants, as they are very likely to rot. During the season of rest, little or no water, but a damp atmosphere, are the chief requirements. Propagated by divisions of the bulbs just after flowering.

> A. africana (African).* fl., sepals and petals nearly 2in. long, greenish yellow, spotted with brownish red; lip small, yellow; spikes large, drooping, branched, each sometimes bearing nearly a hundred blooms. Stems 3ft. to 4ft. high, with light evergreen foliage. Fernando Po, 1844. Lasts two months in perfection.

> A. a. gigantea (gigantic).* fl. on upright spikes from the top of the pseudo-bulbs, but smaller, of a light yellow tint, with very few narrow, transverse, brown bars, and a deep yellow lip, without warts of any kind on its middle lobe, and with more or less crenulated keels. Natal, 1847. The perfume is very peculiar. Very rare.

> A. a. lutea (yellow). Not so strong a grower; producing clusters of light yellow flowers from the top of the pseudo-bulbs. Natal.

> A. a. nilotica (Nile district).* As a garden plant this is much superior to the type. The habit is dwarfer, the colours of the flowers brighter and more distinctly defined. The sepals and petals, too, are more spreading. Eastern Africa.

ANSERINA. See Potentilla anserina.

ANTENNÆ. Two movable, articulated organs attached to the heads of insects and crustacea, commonly called "horns" or "feelers." They are variable in form and length. Antennæ seem to serve for touch, and, perhaps, for smell and hearing.

FIG. 105. ANTENNARIA MARGARITACEA, showing Habit and Inflorescence.

ANTENNARIA (from antennæ; in reference to the similarity which exists between the seed down of the plant and the antennæ, or feelers, of an insect). ORD. Compositæ. Hardy herbaceous perennials, distinguished by the dry, coloured, chaffy scales encircling each head of flowers, of which the stamens and pistils are on different plants. These are charming little alpine plants, admirably adapted for rockwork, pots, edgings, or borders, in any light soil. Propagated by divisions of the roots in spring, and seeds; the latter should be sown in spring in a cold frame. Grown chiefly for their leaves.

> A. dioica (diœcious).* fl.-heads pink, in crowded corymbs, 3in. to 4in. high. June. l. radical ones spathulate, woolly chiefly beneath; upper ones lanceolate. Stems simple; shoots procumbent. Britain. The two or three varieties of this pretty species exceed the type in beauty. SYN. Gnaphalium dioicum.

> A. d. hyperborea (northern). l. woolly on both surfaces.

> A. d. minima (smallest).* A very small growing variety.

> A. margaritacea (pearly).* fl.-heads white, corymbose. August. l. linear-lanceolate, acute, alternate, cottony, especially beneath. Stems branched above. h. 2ft. Naturalised in England and on the Continent. Said to have been introduced from America about the sixteenth century. The prettier but much rarer A. triplinervis, from Nepaul, comes close to this species. See Fig. 105.

> A. tomentosa (downy).* fl.-heads corymbose. Summer. One of the dwarfest and best of silvery-leaved plants, either as an edging for small beds or for covering the higher portions of rockwork; it is much used in carpet bedding. It scarcely grows more than 1in. high, and forms a dense carpet in a short space of time. It should be grown separate from other plants. It is frequently known under the name of A. candida.

ANTERIOR. Placed in front, or outwards.

ANTHEMIS (from anthemon, a flower; referring to their general floriferous character). Camomile. ORD. Compositæ. Receptacle convex, chaffy. Involucre hemispherical or nearly flat; scales imbricated, membranaceous at the margin. Pappus none; ray florets ligulate; disk tubular. This is a large genus, principally of medicinal value, and contains very few species worth the cultivator's trouble. Of easy culture in any ordinary soil. Propagated by divisions.

> A. Aizoon (Aizoon).* fl.-heads resembling a white Daisy; florets of the ray fourteen to eighteen, trifid, twice as long as the breadth of the disk. Summer. l. lanceolate, or broadly so, acutely and deeply serrated, narrowed towards the base, covered with white down; lower ones crowded; stem-leaves rather acute, gradually lessening in size. h. 2in. to 4in. Northern Greece. Free grower, dwarf, and compact.

> A. Biebersteinii (Bieberstein's).* fl.-heads yellow. Summer. l. pinnately divided into linear three-lobed segments, which are covered with white silky pubescence. h. 1ft. to 2ft. Caucasus.

> A. Chamomilla fl. pl. See Matricaria.

> A. nobilis (noble). Common Chamomile. fl.-heads solitary; disk yellow; ray white; scales of the receptacle membranaceous, scarcely longer than the disk. l. bipinnate, segments linear-subulate, a little downy. Stem procumbent, and much branched. England. A very strong smelling plant, of great medicinal value. For culture, see Chamomile.

> A. tinctoria (dyer's). fl. bright yellow, in large heads. July and August. l. bipinnatifid, serrate, downy beneath. Stem angular. h. 1½ft. England. A very pretty plant.

ANTHER. The male part of a flower containing the pollen.

ANTHERICUM (from anthos, a flower and kerkos, a hedge; in reference to the tall flower stems). SYN. Phalangium. ORD. Liliaceæ. A large genus, belonging to the capsular group of the order, and inhabiting, for the most part, the Cape of Good Hope. Flowers white, racemose or panicled, scapose; perianth segments either spreading from near the base or campanulately united; stamens short, with naked or bearded filaments. Leaves radical, filiform or linear. The hardy varieties are now extensively grown, and are among the most ornamental of border plants. They thrive best in rich light soil, and are excellent subjects for pot culture; for which purpose use a compost of fibrous loam, leaf mould, or well-decayed manure, and coarse sand. The pots should be about 12in. across, well drained, and the plants potted just previous to, or so soon as, growth commences. During activity, plenty of water is needed, until the plants have finished flowering, when the quantity may be lessened; but never allow them to get dry. Propagated by division of the roots or seeds, sowing the latter, as early as possible after they are ripe, in a cold frame.

> A. graminifolium (grass-leaved). A garden name of A. ramosum.

> A. Hookeri (Hooker's). See Chrysobactron Hookeri.

> A. serotinum (late-flowering). See Lloydia.

> A. variegatum (variegated). l. keeled, grass-like, striped and margined with white. South Africa, 1875. Half hardy. The proper name of this plant is Chlorophytum elatum variegatum. SYNS. A. Williamsii and Phalangium argenteo-lineare.

> A. Williamsii (Williams'). Synonymous with A. variegatum.

ANTHERIDIA. The reproductive organs in cryptogamic plants, analogous to anthers in flowering plants.

ANTHERIFEROUS. Bearing anthers.

ANTHESIS. The opening period of flowers.

ANTHOCARPOUS. Bearing a fruit resulting from many flowers.

ANTHOCERCIS (from anthos, a flower, and kerkis, a ray; in reference to the radiated corolla). ORD. Solanaceæ. Handsome greenhouse evergreen shrubs, with alternate leaves, attenuated into the petioles or base, thick, sometimes glandularly dotted. Flowers axillary, generally solitary; corolla campanulate. Cuttings strike freely in sand under a bell glass, with a mild bottom heat. So soon as they have well rooted, pot off into very small pots in two-thirds good loam and one of peat. After having made a little headway, the leading shoots should be pinched off, to induce a lateral growth; they may be transferred to pots a size larger when the roots have filled the first pot. Continue growing throughout the summer in frames or in the greenhouse, near the glass, allowing plenty of air. Vigorous growth should be checked; thus encouraging bushy plants.

> A. albicans (whitish-leaved).* fl. white, streaked with bluish-purple inside the tube, fragrant; petals longer than the tube. April. l. oblong, obtuse, densely tomentose on both surfaces, as well as the branches. h. 1½ft. to 2ft. New South Wales, 1824.

> A. floribunda (many-flowered). fl. white. h. 3ft. New South Wales.

> A. ilicifolia (Holly-leaved). fl. yellowish green. June. h. 6ft. Swan River, 1843.

> A. littorea (shore). fl. white. June. h. 3ft. New Holland, 1803.

> A. viscosa (clammy).* fl. large, white. May. l. obovate, glandularly dotted with scabrous margins; young leaves and branches clothed with fine down. h. 4ft. to 6ft. New Holland, 1822.

ANTHOLOMA (from anthos, a flower, and loma, a fringe; in allusion to the fringed or crenulated limb of the corolla). ORD. Tiliaceæ. A very fine greenhouse evergreen tree; it thrives best in a light loamy soil, mixed with a little peat. Cuttings of ripened wood will strike root in sand, under a hand glass.

> A. montana (mountain).* fl. white; corolla ovately cylindrical, with a crenate, rather toothed margin; racemes axillary, somewhat umbellate, reflexed. May. l. elliptical-oblong, leathery, stalked, scattered at the top of the branchlets. h. 20ft. New Caledonia, 1810.

ANTHOLYZA (from anthos, a flower, and lyssa, rage; in reference to the opening of the flowers, which resemble the mouth of an enraged animal). SYN. Petamenes. Including Anisanthus. ORD. Irideæ. A very pretty genus of bulbous plants from the Cape of Good Hope, having narrow, erect, Iris-like leaves, and flower-spikes that over-top the foliage, bearing numerous bright-coloured flowers. Perianth tubular, six-cleft, unequal, the upper segments longest; stamens three. The species may be grown in a greenhouse, or planted out in a frame. They also thrive excellently out of doors, and should be planted 8in. or 9in. deep for fear of frost, or have a winter protection of several inches of cocoa-nut fibre refuse or litter. The safer plan is to raise the roots, winter them in some dry part of the greenhouse; but, previous to storing, divide the clumps, clean them, and re-plant or pot in February, or early in March. A mixture of equal parts peat, sandy loam, and leaf soil is most suitable for their culture. Just previous to flowering, if in pots, frequent doses of weak manure water will be found beneficial. They may be propagated by offsets, which are produced in abundance, at almost any time. Seeds are sometimes procured, which should be sown so soon as ripe, in light soil, in a cool house, where they will germinate the following spring, and will be fit to plant out in the summer of the same year. With the exception of A. Cunonia, they all much resemble each other. Only four or five species of this genus are worth cultivating.

> A. æthiopica (Æthiopian).* fl. scarlet and green. June. h. 3ft. 1759. SYNS. A. floribunda, A. præalta.

> A. æ. ringens (gaping). fl. red and yellow, rather smaller than those of the type. SYN. A. vittigera.

> A. bicolor (two-coloured). Synonymous with A. Cunonia.

> A. caffra (Caffrarian).* fl. rich scarlet; spike distichous, many-flowered. June. l. long, linear, or linear-ensiform. h. 2ft. 1828. A very showy and pretty species, but rarely seen in our gardens. SYN. Anisanthus splendens.

> A. Cunonia (Cunon's).* fl. scarlet and black, a combination of colours uncommon among bulbous plants; spikes secund. June. h. 2ft. 1756. SYN. Anisanthus Cunonia.

> A. floribunda (much-flowered). A synonym of A. æthiopica.

> A. præalta (very tall). Synonymous with A. æthiopica.

[85]

ANTHOTAXIS. The arrangement of flowers on an inflorescence.

ANTHOXANTHUM (from anthos, a flower, and xanthus, yellow). Spring Grass. Calyx of two valves, glumaceous, one-flowered; corolla double, each of two valves: the exterior awned; the interior small, awnless; stamens two, not three, as is usually the case with grasses. ORD. Gramineæ. A pretty native hardy perennial, of easy culture in common garden soil.

FIG. 107. ANTHOXANTHUM ODORATUM.

> A. odoratum (sweet). fl. panicle spiked, oblong, dense, becoming dullish yellow. l. short, pale green. h. 1ft. The pleasant smell of new-made Hay is chiefly owing to this plant, which in drying emits an odour similar to that of Asperula odorata. See Fig. 107.

ANTHURIUM (from anthos, a flower, and oura, a tail; referring to the inflorescence). ORD. Aroideæ. Flowers densely disposed on a cylindrical spadix, at the base of which is a large bract-like spathe, that ultimately bends backwards. Leaves of various shapes. This very large genus of handsome stove and greenhouse plants is remarkable both for the peculiar inflorescence and often noble leaves, and is distinguished in structure from all the European members of the order in the flowers being hermaphrodite. Fibry peat, loam, sphagnum, broken crocks, or charcoal, and silver sand, form the most suitable compost. In preparing the peat, it should be broken up into small lumps, and then have most of the earthy matter knocked out of it by giving it a few raps with a stick, or by shaking it about in a sieve. To this, after so treated, add about one-fourth its bulk of sphagnum, and about half its bulk of fibrous loam, and just a sprinkling of fresh broken crocks, or small pieces of charcoal and sharp silver sand. In placing them in the pots—which must be well drained—carefully spread out the roots and work the mixture among them, keeping the plant well up, so that when finished it stands clear above the rim of the pot at least 2in. or 3in., and forms a kind of mound or hillock. They must then be kept freely syringed or watered, and placed in a moist atmosphere, where they can enjoy a temperature ranging between 60deg. and 70deg., or a few degrees lower for the less tender species. Raising plants from seed requires patience. About a year elapses from the time the flowers are fertilised—which should be done artificially—before the seed ripens, and often another to get up plants. Sow as soon as ripe in shallow, well-drained pans or pots, filled with the potting mixture, and cover slightly, and place in a close, moist propagating case, where a temperature of from 75deg. to 85deg. is maintained, or they may be covered with bell glasses. The principal thing is to keep the air about them constantly humid, and the material in which they are sown in a uniformly moist condition; if this is done, the young seedlings will make their appearance in due course. When these are of sufficient size to handle, they should be pricked off in the same sort of compost, and be kept close and moist till they get a start, after which gradually inure them to more air. January is the best month of the year wherein to propagate these plants by divisions. This is done by carefully turning them out of their pots and shaking out what soil they have amongst their roots, which must be tenderly dealt with, so as not to bruise or injure them. This done, they may then be pulled apart, and as many plants made as there are separate crowns, or the mass may be simply halved or quartered, according to the stock required. Treat now as recommended above for potting. They are all moisture-loving plants, and must have a copious supply of water at all times, although, of course, much less during the winter than spring and summer months. There is no season of the year when they can be handled for any purpose with less risk or check than January. A moderate moist stove heat is advisable for them generally. The species enumerated are selected from nearly 150, and will be found to be a very representative collection. See also Spathiphyllum.

There appears to be much confusion as regards this and many varieties of A. Harrisii; and the specific designation is indiscriminately applied to lanceolate-leaved forms generally. The true species was introduced to Kew from the West Indies. SYN. A. Wildenowii.

> A. leuconeurum (white-nerved). Green. Mexico, 1862.

ANTHYLLIS (from anthos, a flower, and ioulos, down; flowers usually downy). Kidney Vetch. ORD. Leguminosæ. Herbaceous or sub-shrubby plants, of variable habit. Flowers in spikes or heads; calyx tubular, five toothed, permanent after flowering, more or less inflated. Petals nearly equal. Although not extensively grown, all the species are very beautiful when in flower, the hardy sorts being admirably adapted for rockwork. The herbaceous perennials may be easily propagated by seed or division. The seeds of the annual kinds should be sown in a rather dry, warm situation in the open ground. The shrubby evergreens will need the protection of a frame or cool greenhouse in cold northern climates, and are best grown in a mixture of loam, sand, and peat. Young cuttings of most species will root in a pot of sandy soil, with a bell glass placed over them, in a cool house or frame.

> A. Barba-Jovis (Jupiter's beard).* fl. pale yellow, numerous, in globose, bracteate heads. March. l. pinnate, and are as well as the branches, clothed with silky tomentum; leaflets nine to thirteen, oblong-linear. h. 4ft. to 8ft. Spain, 1640. Shrub.

June. l. pinnate, and are as well as the branches, silky and hoary; leaflets numerous, oval-oblong, acute, small, entire. h. 3in. to 6in. Alps of Europe, 1769. A very handsome little rock plant, with a dwarf and tufted habit.

> A. tetraphylla (four-leaved). fl. white; heads axillary, sessile, few flowered. July. l. pinnate, the terminal leaflets ovate and large, the other three small and acute. South Europe, 1640. A procumbent annual.

> A. Vulneraria (Common Woundwort).* fl. generally yellow, sometimes white, red, or pinkish, in crowded twin heads. Summer. l. pinnate, with five or more unequal leaflets; the lower ones smallest. An elegant native herbaceous, perennial, admirably adapted for rockwork. It is plentiful in most dry pastures. There are several varieties, the best of which is alba.

ANTIARIS TOXICARIA. This is the famous Upas tree of Java, from which is obtained poison of a most deadly nature. It belongs to the NAT. ORD. Urticaceæ.

ANTIGONON (from anti, against, or opposite, and gonia, an angle). ORD. Polygonaceæ. Elegant stove climbers. Flowers racemose, cirrhose at the apex of the rachides; petals five, three outer ones broadly cordate, two inner oblong. Leaves alternate, cordate. Although extremely[88] handsome plants, they are difficult to flower. They seem to succeed best when planted out in a very thoroughly drained border over hot-water pipes or flues, the long climbing stems being trained near the glass in full light.

> A. amabile (lovely).* fl. bright rose, profusely borne in axillary and terminal racemes. l. 3in. to 5in. long, ovate-cordate, and deeply lobed at the base. It is of free slender growth, the young shoots are pubescent, and having a slight reddish tinge. An exceedingly attractive and effective species.

> A. guatemalensis (Guatemala). Probably the same as A. insigne.

> A. insigne (remarkable).* fl. very numerous, borne in tufts along the sides of long racemes or panicles, which terminate in branched tendrils; the calyx, which is the showy part of the flower, has five membranous sepals, the three outer are of a beautiful rosy pink colour, about 1in. in length by rather less in breadth, cordate at the base, oblong, rounded towards the apex; the two inner sepals about the same length as the outer ones, but much narrower, falcate, lanceolate; pedicels ¾in. long. l. broadly ovate oblong, deeply cordate at the base, with two rounded lobes; 4in. by 3in., the upper ones smaller, supported on short terete downy stalks. Stems slender, angular, pubescent. Columbia, 1876.

Stem slender, sub-pubescent. Mexico, 1868.

ANTIGRAMME. See Scolopendrium.

FIG. 113. ANTIRRHINUM CAPSULE, with Persistent Style.

FIG. 114. ANTIRRHINUM ASARINA, showing Habit and Flower.

ANTIRRHINUM (from anti, like, and rhin, a nose or snout; alluding to the shape of the corolla). Snapdragon. ORD. Scrophulariaceæ. Hardy herbaceous plants. Flowers in terminal racemes, or solitary and axillary; corolla personate; tube ample, saccate at the base; lobes of the upper lip erect; lower lip spreading, having the middle lobes smaller than the lateral ones, with an ample bearded palate, which closes the throat. Seed pod or capsule two-celled, upper cell bursting by one pore, lower by two many-toothed pores. See Fig. 113. Leaves entire, rarely lobed. The genus contains several very handsome species, suitable for borders and the rockery, while innumerable varieties have originated from A. majus, which are very popular, and extremely useful for bedding purposes; these may be increased by cuttings or seeds; if it is desired to increase certain colours or varieties, the former is the only sure method to adopt. They should be taken in September, when they will readily root in a cold frame, or under a hand glass, or they may be rapidly propagated in gentle heat in spring. Seeds should be sown in July or August, when they will produce good plants by the following season; or if sown in March in warmth, the plants will bloom late in the same year. The "Tom Thumb" strain is especially desirable for bedding, being very dwarf and free. All the other species may be increased by cuttings and seeds treated in the same way. Light soil, well enriched with manure, is most suitable for all of them, especially for the varieties of A. majus.

Spring, summer, and autumn. l. oblong-lanceolate, 1in. to 3in. long; upper ones narrower, attenuated at both ends, glabrous. Branches erect, usually branched again. h. 2ft. Europe (naturalised in Britain). The named varieties are numerous, but it is unnecessary to enumerate any, as an equal amount of variation can be obtained from seed. See Fig. 115.

> A. molle (soft).* fl. few, at the tops of the branchlets; corolla 1in. long, whitish, with a yellow palate; upper lip striped with purple. July. l. opposite, petiolate, clothed with glandular and clammy hairs, about ½in. long, and little more than ¼in. broad; branches procumbent, slender, clothed with woolly hairs. Pyrenees, 1752. A very pretty plant, which should have a warm position on the rockery. A. sempervirens comes close to this species.

West Indies, southwards to New Grenada, 1793.

ANTS (Formicidæ). Well-known pests, easily distinguished from all other insects. There are a great number of species, differing more or less in habits; but, as a rule, they dwell underground in communities, and construct extensive ant-cities, which are occupied by three classes—the neuters or workers (by far the most numerous), the males, and the females. There are often, in addition to these, larger and stronger neuters, known as the "soldiers," or defenders of the community. Ants have a long, slender body, supported on long and slender legs. The head bears a pair of elbowed horns or antennæ, constantly waving about and touching everything the insect comes across. They have powerful mandibles for cutting, sawing, and biting, and it is with these instruments that Ants do mischief in gardens. The winged males and females become mature in summer, and on a warm day they ascend in a body into the air; after a short time, they fall to the ground, the females at once free themselves from the henceforth useless wings, and begin to form new colonies. Vast numbers of eggs are laid, from which issue larvæ, and these soon become pupæ, and then perfect Ants. Some kinds are injurious from their habit (in some species) of collecting aphides together, and farming them for the sake of the honey secreted by the aphides, and that passes out from their honey-tubes (thus helping to perpetuate the stock of these most injurious insects); and also from the mechanical damage they do in pots, and other receptacles for plants. They likewise cause unsightly hills on lawns and paths, and the large black species that live in decayed wood often injure the framing of greenhouses, &c., when the woodwork has become somewhat decayed. Where fruit, such as peaches or wall pears, are grown, Ants will at times inflict damage, and, therefore, they should be kept away; but this is a comparatively easy matter, as the placing of an obnoxious substance along the base of the walls and around the stems of the trees will deter them. For the extirpation of Ants from indoors, the Arsenical solution described below is most efficacious, but it is extremely dangerous.

Lime. Air-slaked lime plentifully dusted, in warm, dry, weather, over and around the hills and other places infested, will cause the Ants to vacate them in a short time. A thick chalk line drawn round a smooth tree, or across an upright board or post, will render it impassable.

Arsenic. This must be used with the utmost caution, as it is a poison most fatal to animal life. Recipe: 1oz. of ordinary arsenic is placed in an old iron pot with a quart of water, and then boiled until reduced to a pint or a little more of liquid, to which is added ½lb. of coarse sugar. This mixture can either be dropped about the runs and around the nests, or placed in saucers in the Ants' haunts.

Ferrocyanide of Potassium. This is also very dangerous: Ferrocyanide of potassium, 1dr.; raspings of quassia, 1dr.; and enough sugar to form a syrup. Use in the same way as the preceding.

Calomel and Sugar. Mix together one part of calomel and ten parts of finely-powdered loaf sugar, and lay it in little heaps about their nests and runs; the Ants will eat it and die. Spring is the best season for this method.

Guano, when fresh, if sprinkled on and around their quarters, is said to be efficacious in driving them away.

Camphor. If a piece of camphor, about the size of a filbert, be placed in two quarts of hot water, and this, when cool enough, applied to pot or other plants infested with Ants, the insects will be driven off without injury to the plants.

Bones. Lay a quantity of partially-picked boiled bones in the haunts, and they will be quickly covered with insects. As soon as this occurs, throw the bones into hot water. Before laying them down again, let all superfluous moisture drain off. This is a cheap remedy, and, if persisted in, is very effectual.

Carbolic Acid. This, if of good strength, diluted with about ten or twelve times its bulk of water, and well sprinkled over paths or other places where there is no vegetation, will keep the Ants away. It has, however, an objectionable smell.

Paraffin Oil. Paraffin, mixed with six times its bulk of water, and sprinkled over the nests every few days, will kill and drive away Ants; but the smell is disagreeable.

Quassia. 4oz. of quassia chips, boiled in a gallon of water for about ten minutes, and 4oz. of soap added to the liquor as it cools, if used like the preceding, is fairly effectual; but this, like the other remedies, must be persisted in for some time.

[90]

Fly pans or saucers, nearly filled with thin honey or sweet oil, attract Ants, and they are drowned in them. Ants are very hard to clear effectually out of a place, and therefore it is very desirable, in all attempts to be rid of them, to persist in the above remedies. When not living close to the roots or stems of plants, the best and surest remedy of all is to flood them out or scald them in with boiling water. The specifics are endless, but the best are mentioned above.

ANTWERP HOLLYHOCK. See Althæa ficifolia.

AOTUS (from a, without, and ous, an ear; in allusion to the absence of appendages in the calyx, which distinguishes it from its allied genus, Pultenæa). ORD. Leguminosæ. Elegant little greenhouse evergreen shrubs, with yellow flowers, and simple, linear-subulate leaves, revolute at the margins, alternate or nearly opposite, or three in a whorl. They should be grown in a compost of equal parts loam, sand, and peat, with a little charcoal, and the pots should be well drained. Cuttings of half-ripened wood, made in April, root freely in sand, under a bell glass.

> A. gracillima (most slender).* fl. yellow and crimson, small, on long, dense, graceful spikes, which are often over a foot long; pedicels short. May. h. 3ft. New Holland, 1844. A very pretty slender growing shrub.

> A. villosa (soft-haired). fl. axillary, disposed in racemose spikes along the branches; calyx silky. April. l. smoothish on the upper surface. h. 1ft. to 2ft. New Holland, 1790.

APEIBA (the native name in Guiana.) ORD. Tiliaceæ. Very handsome stove evergreen trees or shrubs, clothed with starry down. Flowers large, golden yellow, pedunculate, bracteate. Capsule spherical, depressed, rough from rigid bristles. Leaves broad, alternate, entire or serrate. They thrive in a mixture of loam and peat. The best way to induce them to flower in this country is by cutting a ring round the bark of a large branch; by this means the growth is stopped. Well ripened cuttings should be planted in sand in heat, under a bell glass, which should be tilted occasionally, so as to give a little air to the cuttings, otherwise they are apt to damp off.

> A. aspera (rough).* fl. golden yellow; peduncles opposite the leaves, branched, many flowered. May. l. ovate-oblong, somewhat cordate, quite entire, smooth. h. 30ft. to 40ft. Guiana, 1792.

> A. Petoumo (Petoumo). fl. yellow, similarly disposed to A. aspera. August. fr. densely clothed with bristles. l. ovate-oblong, somewhat cordate at the base, entire, hoary beneath. h. 40ft. Guiana, 1817.

> A. Tibourbou (Tibourbou).* fl. dark yellow. August. fr. densely clothed with bristles. l. cordate, ovate-oblong, serrated, hairy beneath. h. 10ft. Guiana, 1756.

APETALOUS. Without petals.

APEX. The summit or point of anything.

APHELANDRA (from apheles, simple, and aner, a male; the anthers being one-celled). ORD. Acanthaceæ. Very handsome stove evergreen shrubs, mostly of an erect habit of growth, and having handsome shining leaves, which in some instances are variegated. Flowers produced in terminal four-sided spikes—the preponderating colours being brilliant shades of orange or scarlet—conspicuously situated above the foliage; they are exceedingly attractive; corolla ringent, two-lipped, upper lip three-lobed; central lobe large. They bloom generally during the autumn months, and if the plants are removed to a warm dry atmosphere so soon as the flowers begin to open, they will continue much longer in perfection than if left in the moisture-laden atmosphere of the stove. From the time the flower spikes are at first seen till they bloom, the plants will derive much benefit from frequent applications of clear manure water. When the plants have finished flowering, they should be allowed to rest, by reducing the supply of water, but never allow them to shrivel. During this time they may be kept in a house or pit, where the atmosphere is rather dry, with a night temperature of 50deg. to 55deg. Here they may remain till March, when they should be pruned. This operation is commenced by thinning out the weakest shoots altogether, and cutting the others back to one or two of the strongest joints or buds above the old wood in order to keep the plants dwarf and bushy. When pruned, the plants should be placed in the stove, giving moderate supplies of water at the roots, and occasionally sprinkling the stems overhead till growth commences. When the young shoots have attained an inch or so in length, the plants should be turned out of the pots, removing the crocks and as much of the old soil as can be got away easily, at the same time shortening-in any of the straggling roots. They should then be placed into smaller-sized pots, keeping them rather close, and watering them carefully for a time till growth has commenced. When fairly started, they may be transferred into larger-sized pots, in which they are to flower. During the summer, these plants require a moist atmosphere, with a temperature of 65deg. by night, allowing it to rise 15deg. or 20deg. by day, and whilst active growth is taking place they should be frequently supplied with moisture at the roots, keeping them well exposed on all sides to the light. After growth has commenced, it is not advisable to stop the shoots, for the stouter and stronger they grow up the finer will be the flower spikes when they appear. The compost should consist of equal parts fibry loam, leaf soil, and peat, with a good proportion of sand added. In preparing it, it should be rather lumpy, and, before using, should be warmed to about the temperature of the house in which the plants are grown. Clean pots and perfect drainage are most essential. Cuttings are best prepared from half ripened wood, or taken off when young with a heel. The base of each cutting should invariably be cut clean across. These may be inserted an inch apart, in pots of sandy soil, and plunged in a brisk bottom heat. To obtain young shoots for cuttings, if the old plants break freely after pruning, and very large specimens are not required, when the shoots are 2in. long they should be thinned out, leaving the requisite number of the strongest to form the plant. If the surplus pieces are removed with a slight heel of the older wood, they make good cuttings, and should be treated the same as the others. These cuttings strike root quickest, and when rooted, if potted into 5in. or 6in. pots, and allowed to grow up without stopping or pinching out the tops, they will flower the first season. Although Aphelandras can be grown into large sized specimens, it will be found to be more generally satisfactory to have specimens of neat and moderate dimensions. The mealy bug and scale insects are very troublesome, and must be kept down, otherwise they will prove most prejudicial to the plants.

APHELEXIS (from apheles, simple, and exis, habit). ORD. Compositæ. A genus of elegant dwarf evergreen greenhouse shrubs. Flower-heads large, solitary, or small and two or more together. Leaves small. These plants are valuable for exhibition purposes, on account of their bright colours, and the length of time they last in perfection; they are included among what are familiarly known as "everlastings." The most suitable soil is a compost of two parts of good fibrous peat and one of leaf mould, with a liberal supply of silver sand, and a few pieces of charcoal added to it. Repot the plants firmly in February, and allow thorough drainage. Cuttings can be made in spring or summer; small half-ripened side shoots are best; and these will root in sandy soil, under a bell glass, in a cool greenhouse.

APHIDES, or PLANT LICE. These belong to the order Homoptera, meaning "same winged," and the name has reference to the fact that the fore wings are uniform in their structure from base to apex, not divided into a leathery base and a membranous tip. Aphides are all minute in size, soft bodied, and generally long legged; the mouth is furnished with a curiously-constructed beak, or rostrum, for sucking the juice of plants; the antennæ, or feelers, are long and slender; the legs have usually two joints in the tarsi, one of which is generally very ill-developed; and near the tip of the abdomen, on the back of a ring, in many kinds, stand two prominent tubes, called honey-tubes, from which a sweet secretion, much sought after by ants, is emitted. They are very destructive, and nearly every plant has its own peculiar Aphis; but among the worst are the cherry fly and bean fly. All these insects are very destructive to the young shoots and foliage of plants, on which they cluster in large numbers, sometimes completely hiding the stems, increasing with marvellous rapidity. They produce eggs in autumn, which lie dormant through the winter, and upon the approach of warm weather in spring, hatch and produce individuals which, during the summer, are viviparous, budding off young insects at a surprising rate, which quickly in turn become possessed of the same marvellous power; hence the enormous number which are produced in so surprisingly short a time. It has been computed that in a few weeks many millions of young might be produced directly or descended from a single female. See also Black Fly and Bean Fly.

The following remedies may be successfully employed:

Tobacco. This is applied, as a rule, in three forms, each of which is useful for particular purposes. Tobacco powder is useful as a dry application to plants where, from any cause, the other modes of employing it are not desirable. It causes no smell, and is useful in conservatories, &c., for that reason. The mode of applying it is to dredge or dust it over the foliage of the plants affected, and to syringe off in from three to thirty hours, according to the nature of the plants. Fumigation with tobacco, if done in a proper way, is very effective, but it leaves an unpleasant smell. The foliage of the plants should be quite dry, and a still day must be chosen for the work; the house should be filled with smoke, but no flame must arise in the burning. The plants should be well syringed the next morning, and full ventilation allowed; if the fumigation is repeated twice or thrice, it will prove very effectual. Tobacco water is made by soaking a pound of coarse shag in 6gals. of hot water, to which ½lb. of size or soft soap has been added. The plants should be dipped into or syringed with this mixture, and well syringed with clean tepid water about twelve hours after. It should not be employed for plants having woolly or hairy foliage. Tobacco paper and cloth are used for fumigating in the same manner as tobacco; but as they vary in strength, more care is necessary, as they sometimes cause the leaves to become spotted. Judiciously employed, they are cheaper than Tobacco.

Quassia. Boil 1lb. quassia chips in 4gals. of soft water, for about ten minutes, and after straining off the chips, add 1lb. of soft soap. Apply in the same way as Tobacco water, and syringe the plants with clean water after ten minutes or a quarter of an hour.

Soft Soap. This, in proportion of 8lb. to 12gals. of rain water, and 1gal. of tobacco water added after it is cold, is a cheap and good remedy out of doors, and requires the same mode of application as tobacco water.

Soap Suds. Where bleaching powder, or much soda, is not mixed with these, they make a good insect killer for hard-foliaged plants, but should be washed off with clean water in twelve hours. No mixture containing chloride of lime should be used.

Various. Fir-tree Oil, Gishurst's Compound, and Fowler's Insecticide, are all serviceable, if used as directed on the labels. Hardeman's Beetle Powder, applied with the little French powder-bellows which is sold with it, is very efficacious. For outdoor work, nothing surpasses clean cold water, applied often and forcibly with a syringe.

The best mode of clearing Aphis off Beaus, Currants, &c., is to remove the tops of the infested shoots, and to wash the plants with soapy water, or a solution of Gishurst's Compound. In some cases, a good dusting with soot and wood ashes, while the plants are wet, will keep them in check. The "Golden Eyes" or "Lacewing" fly, and also ladybirds, are to be encouraged, as the larvæ of each of these wage incessant war against Aphides, especially the green varieties, and thin them out considerably.

FIG. 118. INFLORESCENCE OF APOCYNUM ANDROSÆMIFOLIUM.

APONOGETON (from apon, Celtic for water, and geiton, neighbour; alluding to the habitat of these plants). ORD. Naiadaceæ. Very ornamental aquatic perennials. There are several species, but A. distachyon is superior to the others. This species may be cultivated in small tanks or aquaria; it delights in an abundance of light and air, and is perfectly hardy, having become naturalised in many parts of the country. Pot the plants in rich sandy loam and rotten cow manure, using, of course, small pots, if the vessel in which it is to be grown is restricted. When introducing it to large tanks or lakes, commence with strong, previously well-established plants, in large pots, breaking the latter when the plants are immersed. Place them in positions where the water is about 1ft. 6in. to 2ft. deep; they will then rapidly increase by offsets and seeds, and, when established, will flower nearly all the year round. The other kinds will thrive with the same treatment; but they are neither so hardy nor so vigorous, and should only be grown in small tanks or aquaria.

FIG. 121. APPLE BLOSSOM.

APPLE (Pyrus Malus). The Apple is one of the most useful, and probably most largely cultivated, of our hardy fruits. It is known as the Crab in its wild state, and is indigenous to Britain and to all the temperate and warmer parts of Europe. It is supposed that the progenitors of the varieties now grown were introduced to this country at various times from the Continent, and not obtained here as direct improvements on the native Crab. Those now cultivated are extremely numerous, and include good varieties that can be made to prolong the season all the year round. Apart from its great value as a fruit, the apple is a strikingly handsome tree when in flower (see Fig. 121). A fruiting branch is shown at Fig. 122.

FIG. 122. FRUITING BRANCH OF APPLE.

Propagation. Seeds are sown extensively, chiefly for raising stocks to graft approved sorts on; also with a view to raising new varieties. The seeds do not retain their germinative properties very long, consequently they must be sown soon after being taken from the fruit. As grown in this country, they are generally sown in the autumn, transplanted the following year, and so on until they are of sufficient size for Grafting purposes. The standard of excellence being at present so high, improved forms raised from seed are comparatively scarce.

Grafting. This method of propagation is the one generally adopted for most purposes, the stocks being previously prepared for size or height of tree required. Cordon and other dwarf-trained trees should be worked near but not below the ground, while standards are best worked on stocks of the desired height. The practice of working standard trees low, and growing the scion to form the stem of the future tree, is not recommended, as many of the tenderer sorts will not grow straight or strong enough for the purpose. Whip-grafting is the most preferable mode adopted. The scions should be selected from healthy trees not later than January, and laid in singly in the ground until the stocks have slightly advanced in growth, which is generally about the middle of April. Several other methods of Grafting may be adopted with success, but the one above recommended is considered the best.

Budding. Apples may be successfully propagated by Budding, and this method is practised much more now than formerly. It has many advantages, as it requires to be performed at a season when there is not so much work in hand. It should be done in damp, dull weather, if possible, as the weather if dry soon destroys the buds. July and August is the proper time for the purpose. The stocks and woods from which the buds are taken should be as much as possible in the same condition.

Propagation by Cuttings, Layers, &c. This system may be made use of in the case of new varieties or where it is desired to increase any one variety with a limited number of scions, but the results are uncertain—at least in the case of cuttings; consequently, it is much better to resort to the safer method of Grafting.

Pruning. See Pruning.

Training. See Training.

Planting. The best time to plant is as soon as most of the leaves have fallen, which is generally about the end of October. The roots being then in an active state, and the ground still retaining a certain amount of heat, they will form new roots before winter, which is a material advantage. Where it is impossible to plant at this time, it may be done in suitable weather any time during the winter, but it is best not deferred till spring. It is important in planting that the soil should be moderately dry and free from frost; this condition cannot always be obtained during winter. The effects of soil and situation have a very important bearing on the Apple, specimens of the same sort from different places being often hardly recognisable. Although not over fastidious in the matter of soil as far as growing is concerned, the best results are obtained where it is of a rich loamy character and well drained. Dry, sandy soils invariably produce canker, while the trees are often overgrown with lichens in undrained land. The addition of heavier loam, or sometimes trenching and mixing the sub-soil with that at the top, will convert light soils into those suitable for Apple culture; while, on the other hand, heavy soils may be improved by drainage, the addition of lime, vegetable refuse, burnt earth, and other matters. Rank manure should on no account be used anywhere near the roots, but a little well-decayed manure, mixed with the soil or used as a mulching, is beneficial. The site best suited is an open, though not exposed one, with a south, south-east, or south-west aspect. Shelter from north-east winds in spring, which destroys the bloom, and from west and south-west winds in autumn, which blow down the fruit, should be the aim of cultivators. Planting in a valley should be avoided on account of spring frosts. In Planting, care must be taken to make the bottom of the hole tolerably firm, and slightly raised under the base or bole of the tree. The roots should then be[95] carefully spread out all round, and if any have been ruptured in transplanting, cut them clean off on the upper side, thus inducing new roots to be formed near the surface. The soil should be trodden firmly after a quantity has been filled in, if it is in a dry, suitable condition, as previously recommended. Secure with stakes in proportion to the size of tree, or injury will be caused by the wind. The distance at which Apple trees are planted varies considerably. Standards in orchards may be planted in good soil, from 20ft. to 40ft. apart, especially if they are strong-growing culinary sorts. Pyramids may be planted from 5ft. to 15ft., according to size; and similar distances will suit Bush trees. The oblique Cordon system of training admits of a large number of varieties being cultivated in a small space, as they may be planted as close as 18in. or 2ft. apart. Horizontal Cordons should be planted about 5ft. asunder, and one branch trained each way. Watering will be necessary after planting in most cases, especially should the winter and following season be at all dry. Thinning the fruit is sometimes advisable for obtaining good specimens, but it is not generally necessary, at least with many of the shy-setting sorts. If, however, the crop should be exceptionally heavy, it is best to thin the fruit, or the tree may be unable to make and ripen its wood for the crop of the succeeding year.

Gathering. The three following tests are sure indications of the gathering period: (1) The apples will begin to fall of their own accord; (2) their seeds will be plump and brown in colour; and (3) the fruit will separate with a mere touch from the trees; the second test may be said to be infallible. All Apples should be gathered before the end of October, for none will bear frost with impunity. They must be gathered in dry weather, and handled with the greatest care, laid gently in baskets and trays, in single file only, and conveyed to the store room.

Storing. The simplest and best method is in choosing or forming some room or place free from extremes of heat and cold, dryness or damp, where a temperature of about 45deg. is maintained. A current of air is not necessary. The shelves should be made of poplar, sycamore, lime, or other white wood. Deal, oak, ash, elm, and almost all other woods, give a bad taste to the fruit. One sheet of paper—and paper only—should be placed under the fruit. They ripen best, and are of the highest flavour when left fully exposed to the free atmosphere of the fruit room, and in order to preserve a more even temperature the light should be shut out. Early and late ripening varieties must be stored in separate places, as well as all inferior or injured fruit. The plan of isolating each fruit by packing in tissue paper, sand, burnt earth, or other substances, often destroys the flavour of the fruit, and possesses no material benefit otherwise.

APPLE BERRY. See Billardiera.

APPLE-BLOSSOM WEEVIL (Anthonomus pomorum). This is a small beetle of a reddish-brown colour, with three inconspicuous stripes of a paler colour behind the head; the wing cases show a large pitchy-coloured blotch, with oblique striæ and yellowish spots thereon. The female busily engages herself in piercing the flower buds; while the male may be usually seen flying about the trees during the breeding season, which, of course, varies according to the earlier or later expansion of the buds. The female, by means of strong jaws at the end of the long proboscis, bores a hole in the bud, in which she lays a single egg, finally closing the opening, then passing on to other buds. The laying season lasts for two or three weeks, or, indeed, as long as the buds remain unexpanded; eggs are never laid in open blossoms. In warm weather, the eggs are hatched in six or seven days, usually about the end of April, into small, white, legless maggots, which feed upon the stamens and pistil; hence, although the petals are normally coloured, and expand, the flowers ultimately wither, and in some seasons very serious consequences have arisen from these injurious little pests. The maggot is fleshy, whitish, with a few hairs and a black, hard head; in a few days, it turns into a brown chrysalis or pupa, which, in turn, is changed into the Weevil, only about a month having elapsed from the deposition of the egg till the Weevil is developed. It feeds upon the foliage during summer, and hybernates in crannies of the bark, or under the soil at the base of the trees, during winter, waking up in the following spring to go through the same performances as its parents.

Remedies. Some of the methods advised for the extirpation of the American Blight will prove very useful for the destruction of this pest. Clear away all useless portions of the bark and rubbish round about the tree during the winter, and many will be destroyed. Place bandages of tarred cloth around the stem in spring; this will prevent the females crawling up, as they seldom fly. If a white cloth is placed beneath the tree affected when in bud, and the tree is severely shaken, a large number will be caught, as the Weevil falls to the ground when alarmed. Timely thinning of the trees, allowing the free admission of light and air, is also a very effectual preventive, as it has been proved that the greatest ravages are committed where neglect of this has been the rule; and that, on the other hand, in proportion to its being done, the pest has been lessened in numbers.

APPLE MUSSEL SCALE (Aspidiotus conchiformis). This insect attacks the bark of Apple and Pear-trees. It is in outward appearance like the half of a mussel shell. Under the scale is the insect. It is closely allied to the true scale insects, and has similar habits. The scales are about ⅛in. long, brown, and wider at one end than at the other. The female is like a fat, green, fleshy maggot, without jointed limbs. The eggs of this curious insect are not laid, but simply remain in the body of the mother until she dies, thus leaving a protecting shield or case from which the hatched larvæ emerge. To get rid of this insect, therefore, the females containing eggs should be destroyed. It differs from most other species in the absence of the long tail filaments. If numerous, this Scale causes the trees to become sickly and unfruitful. It is difficult to extirpate.

Soft-soap Lather. When the leaves fall, in autumn, the trees should be treated with a stiff sash-tool, and all the Scale rubbed off, keeping the brush just moist, and not rubbing the buds. Applied for two seasons, this should clear the trees. All loose bark should be removed.

Seal Oil is sometimes recommended as a good remedy: but oils are rather unsafe applications to the bark of trees, especially of the young branches.

FIG. 127. CODLIN MOTH AND GRUB (CARPOCAPSA POMONANA).

APPLE OR CODLIN GRUB (Carpocapsa pomonana). During the month of May, the well-known Codlin Moth (see Fig. 127) lays its eggs in the calyces, usually one in each, of the young, quickly-growing apple. The moth itself is a small insect; the fore-wings are grey, prettily speckled with delicate, darker streaks, and with a curved golden mark on the hinder part, inclosing one of a reddish-brown colour. The hind wings are usually dark, as is also the body. The caterpillar, when hatched, is white, with black head and neck, and with four rows of black marks along the whole body. The colours soon, however, become less decided, taking an indistinct brownish or grey hue. After being hatched, the caterpillar gnaws its way down the fruit, keeping clear of the core, and gradually forces its gallery towards the rind of the fruit, which it finally pierces, the opening serving as the outlet for the dirt. When nearly full grown, it pierces the core and feeds upon the pips, which injury speedily causes the fruit to drop. The insect then emerges therefrom, and finds a suitable shelter in a cranny of the bark, where it spins a cocoon; and, according to British authorities, it remains in the larval state for some weeks, finally assuming the chrysalis form, and thus passing the winter; the moth emerges the following season. Shortly after development, the moths pair, the female depositing eggs in the fruit in June or July, according to the season.

Practically, there is no preventive; but the following hints will serve to greatly reduce the numbers. All apples that fall ere they are ripe should be picked up as promptly as possible, and be given to the pigs; or pigs should be turned into the orchard to clear off the fallen fruit. The following is the only serviceable remedy:

Hayband Trap. This is simply a loosely made hayband twisted around the stems of the trees, about 1ft. from the ground. The grubs, in searching for a suitable place in which to make a cocoon, will generally choose the bands. At the end of the season, all the haybands should be collected and burnt, and the stems of the trees from which they were removed should be cleared of any cocoons which may adhere to them. All loose bark and other rubbish should be removed from the tree trunks, and also from the ground below.

APPLE OR CODLIN GRUB TRAP. An exceedingly ingenious and effective method of alluring that[98] obnoxious pest, the Apple Grub. The trap (Fig. 128) consists of two, three, or more thin pieces of board, 12in. to 20in. in length, and 2in. to 4in. wide, with a screw (a) through their centre. The screw must be long enough to be firmly driven into the trunk of the tree, so as to hold the boards in position. Small slips of wood (b) are inserted between the boards, to keep them sufficiently open to allow of the entry of the grubs, as shown at d. The boards are cut on each side of the screw, as at c, to facilitate their separation when fastened together by the silken threads of the grubs, and to better expose the latter when the trap is opened. This handy trap, which is of American origin, is very cheap. A great number of them may be collected with little trouble, submitted to a killing heat, and replaced again; and they can be used either on the ground or on the trees. As regards killing the grubs when caught, Mr Weir, the inventor, says: "The quickest and best way is to have a large tin pan, bent in on one side, so as to fit closely to the trunk of the tree. When you reach the tree, drop upon your knees, place the depression in the pan against the trunk of the tree, hold it there by pressing your body against it, and you have both hands free to open the trap. When opening it, many of the pupæ or chrysalids will fall into the pan. The trap must be turned clear around, as many will be found between it and the bark. A person will open and kill the worms in from four hundred to eight hundred traps in a day."

APRICOT (Armeniaca vulgaris). The Apricot, or, as it was formerly written, "Abricock," is a much esteemed and luscious fruit. It is said to have been introduced into this country during the reign of Henry VIII. The Apricot is one of the earliest flowering of fruit-trees (see Fig. 129), and is generally in bloom during February. This fact is a great drawback, as it is a difficult matter to save the flowers from destruction by the spring winds and frosts. The fruit (see Fig. 130) contains less acid than most stone fruits, and in appearance it is perhaps the handsomest of all. Success with its culture in many gardens is by no means certain, but with careful preparation of borders and protection of the flowers in spring, satisfactory results are often obtained. Large quantities of fruit are annually imported to this country from France; but their quality and flavour cannot be compared with that of good home-grown produce.

FIG. 129. BLOSSOM OF APRICOT.

Propagation is effected by seeds or budding. The stones, selected from the best varieties, may be sown as soon as the fruit is ripe, in August or September, in light rich soil, and covered with about 2in. of earth, over which a little litter should be spread during winter. After one season's growth, the plants should be lifted, and the tap roots slightly cut back if the trees are intended for walls. They should then be planted in nursery lines, allowing about a yard between the rows, and 2ft. from plant to plant.

FIG. 130. FRUITING BRANCH OF APRICOT.

Budding is the most general mode of propagating Apricots. They are frequently budded from the beginning to the middle of June on seedling, and also on plum stocks, of which latter the Mussell, Saint Julien, Brussels, and Black Damson are the best. For dwarf trees, the stock should be budded about 1ft. from the ground. There are many disadvantages in having a great length of stem. "Rider" trees require a stem from 3½ft. to 6ft.; half-riders, 2½ft. to 3ft. Grafting by the Whip method is sometimes employed, but, for many reasons, it is much inferior to Budding.

Planting, &c. South-west and western aspects suit the Apricot best, but the fruit has been ripened in warm localities on walls facing several points north. Large areas of garden wall (see Figs. 131 and 132), the walls of stables,[99] barns, outbuildings, and two sides of at least hundreds of cottages, might thus be utilised for the cultivation of this tree. If well drained, almost any garden soil will bring these fruits to perfection; light, fibrous, rather sandy loam will, however, prove most satisfactory. There should be a considerable depth of soil; a yard is not too much, provided it be on a dry base, which is most important. Heavy soils may be improved for Apricot culture by the addition of an equal portion of light loam, mortar rubbish, or charred refuse. In furnishing walls, the distance apart may vary from 2ft. between Cordons, to 12ft., 15ft., or even 20ft. between Fan-shaped trees. The roots should be carefully arranged, interlayered at all points with fine soil, and the whole covered to a depth of 3in. or 4in. Not only should the roots have a good covering of suitable earth, but a secondary one of litter, or other light material, should be added, to render them frost proof in winter, and drought and heat proof in summer. Newly planted trees should, on no account, be allowed to get dry at the root. A thorough soaking of soft rain, or manure water, will often save a crop, and restore the trees, when all other surface remedies or appliances fail. Surface sprinklings overhead with the garden engine, in the afternoons of bright days, are beneficial, and help to keep the foliage clean and healthy. So soon as the trees are cleared of their fruit, attention should be directed to the maturation of the wood. All superfluous shoots should be removed, any excess of growth left on the shoots cut back, and every effort made to perfect the wood already made, rather than force the tree to make more. Unless the weather be very dry, water should not be applied after this stage.

FIG. 131. APRICOT TREE, showing method of Wall Training.

Protection. It is almost hopeless to expect a crop unless the blossoms are protected, by mats or other means, from spring frosts. Temporary wooden copings, from 1ft. to 2ft. wide, laid on iron brackets, are indispensable for warding off storms, and keeping other coverings away from the flowers. These should not be put up till the trees are just bursting into bloom, and may safely be removed about the end of May. A few fish or other nets, spread over the trees, afford considerable resistance to the radiation of heat. This is assuredly one of the easiest, if not one of the most efficient, modes of protection. Frigi-domo and other thick shadings are sometimes used, but they require to be removed from the trees in the day time. The thinner nets mentioned are generally not in use for other purposes at this time of year, and may remain over the trees altogether. Glass copings are the best, but, being rather expensive, they cannot be used by the majority of cultivators. They have, however, been applied with good results to trees that had previously failed.

FIG. 132. APRICOT TREE, showing method of Training suitable for Gable Ends of Cottages.

Cropping, &c. Thinning of the fruit needs early and careful attention. The average of 3in. apart may be chosen for a maximum yield. As the fruit approach maturity, overhanging leaves, or branches of young wood, must be removed, to admit sun and light to properly ripen and colour them. Apricots for preserving should be gathered quite dry, and with the sun upon them. For dessert, they should be plucked in the morning, and placed in a cool room till wanted.

Under Glass. The Apricot will hardly bear forcing. It is more sensitive to heat than almost any other of our semi-hardy fruits. Practically, it is found that a confined atmosphere, or the slightest excess of heat, brings its blooms off in showers, and this, of course, mars all prospect of fruit. But in cold climates and northern latitudes under glass is the best and only means of growing them. Should red-spider appear, it is proof that the roots or the atmosphere, probably both, have been too dry; more moisture, and syringing over the leaves, are the surest remedies. The borders need to be about 2ft. or 2ft. 6in. deep, of any light rich soil. Fresh planted trees should be frequently syringed overhead before and after the flowering period. After they have become fully established, less overhead sprinkling is needed. During all the earlier stages of growth, and until the fruit are stoned, an artificial temperature of 45deg. should not be exceeded. After that stage, the fruit will bear a heat of 50deg. or 55deg. It is hardly safe or desirable to exceed the latter under glass, and unless abundance of air is given, 55deg. may bring off the fruit, even at an advanced stage. A thorough soaking, at intervals of fourteen days during the height of the growing season, may be applied; and, should the trees be heavily cropped, manure water may be given at every alternate watering. It is also a good practice to mulch the surface of heavily cropped trees with 3in. or 4in. of good dung. The fruit should, however, be freely thinned to distances of from 4in. to 6in. apart at the most. There are three general methods of growing them under glass: The trees may be trained on trellises or walls; grown as natural standards, tall or dwarf; and as bushes, either planted out or in pots.

Varieties. The varieties of Apricot, unlike most other fruit, are not numerous; and the following will be found in every way representative and satisfactory:

> Blanche, or White Masculine. A small and delicate fruited sort. Fruit pale whitish-yellow, tinged with brownish-red next the sun, covered with a fine white down; rich, delicate, and sugary.

> Blenheim, or Shipley's.* Very early and prolific. Colour deep yellow; flesh medium, rich, and juicy. Ripe in July.

AQUATIC PLANTS. The culture of Aquatic Plants, both indoors and in the open air, has been greatly neglected of late years; they are, therefore, rarely seen to perfection in places other than where their culture is made a speciality. Generally speaking, they are most easily grown. The following stove and greenhouse genera are well worth attention: Aponogeton, Cyperus, Damasonium, Herpestis, Limnocharis, Nelumbium, Nymphœa, Ouvirandra, Pistia, Pontederia, Salvinia, Thalia, Trianea, Victoria. Many species belonging to some of the foregoing genera are hardy, as are also the following: Alisma, Butomus, Calla, Hottonia, Menyanthes, Nuphar, Polygonum, Sagittaria, Trapa, Typha, Villarsia.

AQUATICUS. Living in water.

AQUATILIS. Living under water.

AQUIFOLIACEÆ. See Ilicineæ.

AQUILEGIA (from aquila, an eagle; in reference to the form of the petals). Columbine. ORD. Ranunculaceæ. Erect hardy perennial herbs with fibrous roots. Flowers solitary or panicled, drooping; sepals five, petaloid, deciduous; petals five, concave, spurred; spurs very large, produced downwards into hollow tubes, and frequently curved at the extremity; carpels five, sessile, free. Radical leaves on long stalks, twice or thrice ternate, with trifid-toothed, usually blunt segments. Too much praise can scarcely be lavished upon this elegant genus of plants. They prefer a moist and sheltered situation, with exposure to the sun. The more robust species will thrive in ordinary garden soil, but the rarer and more delicate kinds require a good friable sandy loam and leaf soil, with good drainage. Seed is produced in abundance, and must be sown very thinly, as soon as practicable after being ripe, in a shady place or in pans in a cold frame. When up, and strong enough to remove, the seedlings may be planted out where they are to bloom, allowing every plant at least 9in. each way. The strong-growing kinds may be placed in the border, the dwarf ones on the rockery. When in bloom, the inferior sorts should be weeded out, retaining only the best varieties. To obtain seed true of any species, it is absolutely necessary to plant the separate kinds far apart, and cover them with fine muslin, to prevent the access of insects to the flowers, as none are more easily cross-fertilised. Division of the root is the only way to perpetuate any particular variety with certainty, unless seed is saved in the way mentioned, or imported from the native habitats of particular species. There are many beautiful hybrids, as well as species, in cultivation.

May to July. l. biternate. h. 1½ft. to 2ft. Himalayas, 1839. This requires a warm position.

> A. glandulosa (glandular).* fl., sepals bright lilac blue, about 1½in. long, more than twice the length of the petals' limb; petals white; spur ¼in. long, or but little more, stout, much incurved; stems one to three-flowered. Spring. l. biternate. h. 8in. to 12in. Siberia, 1822. Extremely pretty. See Fig. 135.

> A. g. jucunda (pleasant). fl. rather smaller. Very handsome little plants, freely hybridised, and it is necessary to keep raising fresh batches, as they are scarcely more than biennial.

> A. glauca (glaucous). fl. white, tinted claret, fragrant; sepals 1in. long, not reflexing; limb of petals ¾in. long; spur straight, or a little curved, about ⅓in. long; stem three to four-flowered. June. l. biternate. h. 1ft. to 1½ft. Himalayas, 1839. Rather tender; plant in a warm dry position.

Summer. l. biternate. h. 1ft. Siberia, 1806. Rockery species. Here are referred, by Mr. Baker, A. bicolor, A. Garnieriana, and A. speciosa. See Fig. 137.

> A. thalictrifolia (Thalictrum-leaved). fl., sepals oblong, acute, lilac blue, about ½in. long; limb of petals about as long, and rounded at the top; spurs slender, not quite as long as the sepals; stems about three-flowered. Summer. l. with three-stalked segments cut into deep oblong lobes. h. 2ft. Tyrol, 1879. Entire plant clothed with fine pubescence.

> A. viridiflora (green-flowered). fl., sepals oval-oblong, shorter than the petals; spurs straight and longer than the petals; stems two to three-flowered. h. 1ft. to 1½ft. Siberia, 1780. Border. Rather a pleasing and sweet-scented green-flowered species, but not very ornamental.

AQUOSUS. Watery.

ARABIS (origin of the word not clear). Wall Cress; Rock Cress. ORD. Cruciferæ. Hardy perennial trailers, except where otherwise stated. Flowers mostly white; racemes terminal; pedicels bractless. Radical leaves usually stalked; cauline ones sessile or stem-clasping, entire or toothed, rarely lobed. Most members of this genus are peculiarly well adapted for rockwork and the alpine garden, both from their natural hardihood as well as their early and profuse flowering habits. They are of the easiest possible culture in any dry soil. The perennial species may either be increased by divisions of the root, by cuttings, placed in a shady border during the summer, or by seed. The latter may be sown outside, or in pans, in spring, when most of them will germinate in two or three weeks. The annuals and biennials are for the most part devoid of any cultural beauty.

> A. albida (whitish).* fl. white; racemes terminal; pedicels longer than the calyx. January to May. l. few-toothed, hoary, or downy with branched hairs; radical ones obovate-oblong; cauline ones cordately sagittate, clasping the stem. h. 6in. to 9in. Tauria and Caucasus, 1798. SYN. A. caucasica.

> A. a. variegata (variegated).* A very pretty variegated form for edgings.

FIG. 138. ARABIS ALPINA, showing Habit and Flowers.

> A. alpina (alpine).* fl. white, smaller than those of A. albida; racemes terminal; pedicels longer than the calyx, which is smoothish. March to May. l. many-toothed, lanceolate, acute, villous with branched hairs; radical ones somewhat stalked; cauline ones cordate, clasping the stem. h. 6in. European rocks, in sunny places, 1596. There are one or two varieties, including a variegated-leaved form, in cultivation. See Fig. 138.

FIG. 139. ARABIS ARENOSA, showing Habit and Flowers.

> A. arenosa (sand-loving).* fl. rose coloured, very rarely white or bluish; petals obovate; pedicels spreading. April to July. l. villous, with forked hairs; radical ones pinnatifid, with the upper lobes much larger than the lower; cauline ones deeply toothed. Stem branched, hispid, with simple hairs. h. 6in. Middle Europe, 1798. See Fig. 139.

> A. blepharophylla (fringed-leaved).* fl. rosy purple; petals roundish, narrowing to the base, with slender claws. Spring. l. naked, except the margins, which are fringed with very stiff hairs; radical ones spathulate; cauline ones oblong, sessile. h. 3in. to 4in. California, 1874. This succeeds best in a cool frame, where it will flower in January.

> A. caucasica (Caucasus). A synonym of A. albida.

> A. lucida (shining).* fl. white; petals entire, narrowed at the base, twice as long as the calyx. Summer. l. obovate, thickish, shining, clasping the stem. h. 4in. to 6in. Hungary, 1790. A very pretty species, with a dwarf habit; it is especially adapted for edgings, borders, or rockwork.

> A. l. variegata (variegated).* A great improvement upon the type, being broadly edged with yellow, and the green somewhat lighter. When grown in tufts or as edging, it is very effective, and should be prevented from flowering. This exceedingly desirable variety is a gem for the rockwork, and when seen in crevices, or in bold tufts, it is very striking. It must be increased by slips or rootlets, which should be taken in early summer.

> [103]

> A. mollis (soft). fl. white, in terminal racemes. May to July. l. grossly toothed, somewhat pubescent, with small stellate hairs; lower ones on long petioles, cordate-roundish; cauline ones ovate-cordate, clasping the stem. h. 2ft. Caucasus, 1823.

> A. petræa (rock).* fl. white; petals ovate, with stalks. June. l. smooth, ciliated or scabrous, with simple or bifid radical ones on longish stalks, entire, toothed; cauline ones oblong-linear, entire, or toothed. h. 3in. or 4in. Britain.

> A. præcox (early). fl. white; petals obovately cuneated, double the length of the calyx. April to June. l. oblong, acute, sessile, quite entire, smooth. Stem covered with close pressed rigid hairs. h. 6in. to 9in. Hungary.

> A. procurrens (procurrent). fl. white; petals obovate, double the length of the calyx. May and June. l. ovate, quite entire, smooth, ciliated with two-parted hairs; radical ones narrowed into a petiole; cauline ones sessile, pointed. Stolons creeping. h. 9in. Servia, 1819. There is a brilliantly variegated form of this pretty species well worth growing.

> A. rosea (rosy).* fl. rosy purple; petals oblong, somewhat wedge-shaped, double the length of the calyx; pedicels longer than the calyx. May to July. l., cauline ones oblong, somewhat cordate, and rather stem-clasping, scabrous with branched hairs. h. 1ft. Calabria, 1832.

> A. verna (spring). fl. small, purple, with a white claw; pedicels shorter than the calyx. May to June. l., cauline ones cordate, clasping the stem, toothed, scabrous with three-parted hairs. h. 3in. to 6in. South Europe, 1710. The best annual species.

ARACEÆ or AROIDEÆ. An extensive order of herbaceous plants, with tuberous rhizomes. Flowers on a spadix, unisexual or hermaphrodite, protected by a spathe. Leaves large, radical. Well known genera belonging to this order are: Alocasia, Arum, Caladium, Colocasia, and Dieffenbachia.

ARACHIS (from a, without, and rachis, a branch; plant branchless). Ground or Earth Nut. ORD. Leguminosæ. A stove annual, of economical value. Corolla resupinate; calyx a long tube, with a bilabiate limb; ovary stipitate, inclosed in the tube of the calyx; the stipe at first short, but afterwards becoming elongated. Sandy loam is the soil most suitable for their cultivation. Seeds should be sown in heat; and, when the plants have grown to a sufficient size, they should be potted off singly, and placed among other stove annuals. After the plant has finished flowering, and the pods begin to lengthen, the pedicels force them into the earth, where they ripen their seeds.

> A. hypogæa (underground). Monkey Nut. fl. yellow, five to seven together in the axils of the leaves. May. l. abruptly-pinnate, bearing two pairs of leaflets, without any tendril; stipulas elongated, adnate to the petioles. h. 1ft., or procumbent. South America, 1812. See Fig. 140.

ARACHNIMORPHA. A synonym of Rondeletia (which see).

ARACHNOID. Resembling a cobweb in appearance; seeming to be covered with cobweb, in consequence of the entanglement of long, white hairs.

FIG. 140. ARACHIS HYPOGÆA, showing Leaf, Flower, &c., and Cluster of short wrinkled Pods.

ARALIA (meaning unknown). ORD. Araliaceæ. This widely-grown genus includes stove, greenhouse, and hardy, herbaceous and shrubby plants. Flowers inconspicuous, umbellate, the umbels usually disposed in panicles; petals five, inserted on the margin of the disk; stamens five (see Fig. 142). Leaves usually compound. These plants are of moderately free growth, and the majority are easy to manage. Those requiring indoor treatment thrive well under the ordinary routine of management. One most important requirement, however, is that they must be kept well supplied with water at the roots. The finer, or stove varieties, should be potted in a mixture of sandy loam and peat, with the addition of a little fibrous leaf soil, and sufficient sand to keep the whole porous. The stronger growing kinds thrive in a richer compost. Propagation by cuttings of the roots is a common and very successful method. To obtain the roots, one of the strongest plants should be turned out of the pot, and the roots should be cleared of soil by shaking or washing it out; the requisite number of pieces should then be selected. As each piece is removed, it should have the end nearest the stem cut horizontally, to distinguish it from the other or furthermost end. In planting cuttings of the roots, it is best to place the end nearest the stem uppermost. The pieces may be left about 2in. long, and should be inserted in pots, well drained, and filled with sandy soil, leaving the tops of the cuttings about level with the surface of the soil. A square of glass must be placed over the top of each pot, plunging them in moderate bottom heat. The stems of the plants from which the roots have been taken may be cut into pieces 1in. or 1½in. long, leaving an eye or bud near the top; a slice of half the shoot may be taken off opposite the bud. When prepared, these pieces should be pressed into pots of sand or sandy soil, and plunged into bottom heat. The stems may be cut down without disturbing the roots; in that case, if the pots are plunged in bottom heat, and kept moderately supplied with water, they will probably throw up several suckers or shoots from the roots. These, if taken off with a portion of root to each, and placed in small sized pots, will, with a little care, soon make useful plants. All the hardy species and most of the greenhouse ones are propagated readily by[104] cuttings or pieces of roots. Some of the stove species, however, are very difficult to increase, except by grafting. Among these are A. leptophylla, A. Veitchii, &c. These should be worked on stocks of A. Guilfoylei or A. reticulata, the latter being the better of the two. Cuttings of either of these strike readily, and stocks fit for grafting are easily procured. In sheltered and warm positions, the greenhouse species are admirably suited for sub-tropical gardening, either planted singly or in groups. See also Dimorphanthus, Fatsia, Hedera, Heptapleurum, Monopanax, Oreopanax, and Panax.

ARALIACEÆ. An order of trees, shrubs, or (rarely) herbaceous plants, often pubescent, and sometimes spiny. Flowers variously disposed, hermaphrodite or unisexual, regular; petals usually five, and valvate. Leaves alternate, or (rarely) opposite. This order is closely allied to Umbelliferæ; and the best known genera are Aralia and Hedera.

ARAR-TREE. A common name for Callitris quadrivalvis (which see).

ARAUCARIA (from Araucanos, its name in Chili). SYN. Eutacta. ORD. Coniferæ. A noble genus of diœcious or sub-diœcious evergreen trees, with usually imbricated persistent flat sessile scale-like leaves. Male cones large, cylindrical, terminal; female ones very large, globular, terminal, with dense ligneous deciduous scales, each bearing a solitary seed. The majority of the species are not, unfortunately, sufficiently hardy to withstand our[106] winters out of doors. Few trees can compete with them in symmetry and elegant proportion for conservatory decoration, where they may be grown in large tubs, or planted out. Small plants grown in pots are most serviceable for table and other decorative purposes. They thrive in a good fibrous loam, mixed with leaf soil and sand. Propagation by means of seed is the surest and most satisfactory method; the seed should be sown in pans or boxes, or if in large quantities, in a bed, with but gentle heat; they usually take some time to germinate. Cuttings are procured by taking off the leading shoots, and fixing them firmly in a pot of sand; they first require a cool place, but may afterwards be subjected to slight warmth. When rooted, they should be potted off into the soil above mentioned. The young growths which afterwards shoot from the plant, whence the cutting, may be taken off and treated in much the same manner. These are the only methods of propagation worth pursuing.

> A. Balansæ (Balansa's). male cones cylindrical-conical, 2in. female cones elliptic globose, 4in.; scales obovate, cuneate. l. arcuately-uncinate, ovate triangular, imbricated round the distichous, simple branchlets. h. 130ft. to 160ft.

Bidwillii (Bidwill's).* Bunya-Bunya Pine; Moreton Bay Pine. cones sub-globose, longest diameter 10in. to 12in., shortest 9in. to 10in. l. ovate-lanceolate, in two nearly horizontal rows, acuminated, slightly convex above, concave beneath, leathery, deep shining green. h. 150ft. Moreton Bay. Habit very regular and symmetrical. Greenhouse species.

> A. brasiliensis (Brazilian). l. oblong-lanceolate, much attenuated at the point, loosely imbricated, deep green; lower part of the trunk usually free from branches, terminating in a rounded head. h. 70ft. to 100ft. Brazil, 1819. A. b. gracilis, and A. b. Ridolfiana are two forms of this species.

> A. columnaris (columnar). A synonym of A. Cookii.

> A. Cookii (Cook's).* l. awl-shaped, short, densely imbricated around the frondose branches. Described by Mr. Abbay as having "a somewhat curious habit, even when growing alone, of shedding their branches for five-sixths or more of their height, and then replacing them by a smaller and more bushy growth, so that the tree at a distance presents a very columnar appearance, the resemblance being increased by the summit being crowned with a mass of foliage somewhat like a capital." h. 200ft. New Caledonia, 1851. SYN. A. columnaris.

FIG. 144. ARAUCARIA EXCELSA.

> A. Cunninghami (Cunningham's).* l. on the sterile branches needle-shaped, obscurely quadrangular, rigid, acute; on the fertile branches shorter, stouter, closely appressed, bright green; upper branches ascending, lower ones horizontal. h. 100ft. Moreton Bay. This fine species we have found to be quite hardy on the south-west coast of England.

> A. C. glauca (milky-green). A very handsome variety, with silvery glaucous leaves.

> A. excelsa (lofty).* The Norfolk Island Pine. l. awl-shaped, curved, sharply acuminated, bright green, densely packed on the frondose, deltoid, horizontal, or pendulous branches. When well grown, this is a beautifully symmetrical greenhouse or conservatory species, attaining to a height of 150ft., and a circumference of 20ft. or more. Norfolk Island. This is especially desirable in a small state. There are several varieties known, the best being: A. e. glauca, having lighter green, and very glaucous foliage; and A. e. robusta, which is larger in all its parts. See Fig. 144.

> A. Goldieana (Goldie's).* Allied to A. Rulei. l. produced in whorls, pendulous, dark green, varying in size. New Caledonia. Most distinct and elegant for conservatory decoration.

> A. imbricata (imbricated).* The Monkey Puzzle. fl., male and female catkins on separate trees; the males are six or seven in a cluster, pedunculate, yellow, and oval with numerous scales, imbricated, long, and recurved at the points; the female catkins are oval, with numerous wedge-shaped scales, with narrow oblong brittle points; they are produced at the ends of the branches. cones, when fully ripe globular, from 3in. to 4in. in diameter, dark brown. The branches are horizontal, inflexed, and ascending at the extremities, and are produced in whorls. l. ovate-lanceolate, sessile, thickened at the base, stiff, leathery, straight, somewhat keeled-shaped below, and strongly mucronate at the apex; verticillate, with seven or eight in a whorl, imbricate, and closely encircling the branches, concave, glabrous, shining, marked with longitudinal lines, dotted on both sides. h. 50ft. to 100ft. Chili, 1796. A well known hardy tree, of striking aspect, and indispensable to Arboreta and shrubberies. See Fig. 145.

> A. Rulei (Rule's).* male cones oblong obtuse; female cones oval. l. oblong-lanceolate, with a prominent dorsal nerve, more closely appressed, and less sharply pointed than in the foregoing species; imbricated in four rows. Branches horizontal; branchlets often quite pendulous. h. 50ft. Papuan Archipelago.

> A. R. elegans (elegant).* l. smaller; whorls of branches closer together; branchlets more slender. An elegant form; and, from its comparative dwarf and graceful habit, should be very generally grown.

ARBOR. A tree. A perennial plant, having a distinct bole or trunk, from which the main branches grow.

ARBORESCENT. Having a tendency to become a tree.

ARBORETUM. A collection of hardy trees formed for pleasure or instruction, and which, when well managed, is a source of much interesting study. They afford shelter, improve the local climate, renovate bad soils, &c., and also, by concealing or hiding disagreeable objects, heighten the effect of agreeable ones, create beauty, and add value. A properly arranged Arboretum should be constructed with a view to picturesque beauty, and not systematically, as is usually the case in Botanic Gardens, although scientific purposes are best served by a systematic arrangement.

ARBOUR. A seat surrounded by lattice work, covered by Vines, Wistarias, or other climbing plants.

ARBUTUS (from arboise, Celtic for austere bush; in allusion to the austere quality of the fruit). Strawberry Tree. ORD. Ericaceæ. Trees and shrubs, with evergreen alternate laurel-like leaves. Corolla globose, or ovately campanulate; petals five, reflexed. Very ornamental subjects for lawns and shrubberies, thriving well in a light sandy or peaty soil. They may be propagated by seeds, which should be sown in sand during March; by budding, and by inarching; the first mentioned method is the one most generally employed, with good results. The various sorts may be grafted, budded, or inarched upon A. Unedo. The greenhouse species are rare in cultivation, but their management does not materially differ from other plants requiring a similar temperature.

ARCTOTHECA (from arktos, a bear, and theke, a capsule; so named from the roughness of the fruit). ORD. Compositæ. Greenhouse herbaceous perennial, allied to Arctotis. Heads radiate; involucral scales imbricate in many rows, the outer linear, herbaceous, inner larger, scariose, very obtuse; receptacle honeycombed, bearing many little fringes; achenes ovate, somewhat four-sided, without wings or pappus. It thrives in a compost of peat, leaf soil, and loam. Propagated by divisions of the plant, or cuttings, in spring. Several species formerly classed in this genus are now included under Arctotis.

ARCTOTIS (from arktos, a bear, and ous, an ear; in reference to the shaggy fruit). ORD. Compositæ. Mostly half-hardy herbaceous perennials. Involucral bracts numerous, imbricated, scariose on the margin; receptacle pitted, studded with bristles between the florets; achenes grooved, crowned with a pappus of membranous scales. The species of this genus are of easy culture in a compost of loam and leaf soil. Propagated by cuttings at any time of the year; these should be pricked in pots of very sandy soil, and placed in gentle warmth; they must be kept uncovered and moderately dry, or they will rot. The Arctotis are very handsome plants in sunny, dry positions outside during the summer months, but they must be protected during winter.

ARCUATE, ARCUATED. Curved or bent like a bow; forming an arch.

ARDISIA. (from ardis, a point; in reference to the acute, spear-pointed anthers). SYN. Pyrgus. ORD. Myrsineæ. An extensive genus of greenhouse or stove, mostly ornamental, evergreen trees and shrubs. Flowers white or rose-coloured, more or less panicled; panicles sometimes many-flowered at the extremities of the branches, and longer than the leaves, sometimes few-flowered and in the axils of the leaves. Leaves alternate, rarely almost opposite, or three in a whorl, dotted. Propagated by cuttings of the half-ripened wood taken from the side shoots of the plant any time from March to September; but, as the points of these side shoots bear the blossoms and fruit, they are not well adapted for making good plants. To obtain the best plants, the largest, ripest, and best-coloured berries should be sown early in spring, as soon as gathered, in a wide-mouthed pot or seed pan, well drained and filled with loam and peat in equal parts, with the addition of some sand, and plunged in bottom heat, the soil being kept moderately moist. The seeds will germinate in a few weeks after sowing, and when about 2in. high, the strongest seedlings should be selected and placed in 3in. pots, the same mixture of soil being used, with the addition of a fourth part well decomposed manure. After potting, the plants must be moistened overhead twice a day with a fine rose or syringe, and be kept in a close atmosphere until the roots have taken to the fresh soil.[109] When the plants begin to grow again, they should be removed to a light situation in the house; and when the pots are well filled with roots, a shift into 6in. pots may be effected, water being given judiciously until well established, and here they may remain to fruit. Until the berries are coloured, clear manure water, given once or twice a week, will be found beneficial. The plants arrive at their best when about 18in. or 2ft. high; after that, they begin to get naked at the bottom. It will then be wise to cut the worst plants down to within 2in. of the pots, in early spring, allowing them to become dry at the roots before this operation is performed. By giving moisture to the roots when the cut has become dry, the plants will soon break into growth again, when some of the worst placed shoots should be rubbed off, leaving only one or two of the strongest and best placed, calculated to develop into a well formed plant. When the shoots have grown 2in. or 3in., the plants should be turned out of their pots, the soil shaken out from the roots, and the long ends of the roots trimmed in a little with a knife; they must then be placed in a pot sufficiently large to hold the roots without squeezing. The plants should now occupy the warmest end of the house in which they are grown, care being taken in watering until new roots are formed, when they may have more air and somewhat liberal supplies of water. As soon as they are sufficiently advanced in growth, they should be transferred to a larger-sized pot. With proper treatment, they will flower and fruit the same season as they are cut down, and form handsome plants. Although most species of this genus are classed as stove plants, they will succeed very well in a temperature that does not fall below 45deg. in winter; and, when so grown, they are not so liable to become infested with large brown scale and other insect pests. This is particularly the case with A. crenulata, and cool treatment is also favourable to the ripe berries hanging on the plants for a much longer time than when grown in a stove. Moreover, they do not suffer so much when removed for decorative purposes.

> A. acuminata (taper-pointed). fl. nearly white; petals small, acute, dotted; panicles terminal and axillary, many-flowered. July. l. entire, glabrous, oblong, acuminated, attenuated at the base. h. 6ft. to 8ft. Guiana, 1803.

Berries numerous, bright coral-like. l. lanceolate-ovate, tapering at both ends, repandly crenulated, pilose. h. 3ft. to 6ft. Mexico, 1809. When grown in a cool atmosphere, as previously alluded to, it is quite common for one crop of berries to hang on the plants until another crop is ripe. This is a splendid plant, superior even to the red-berried Solanums for decorative purposes, for which it is largely grown. See Fig. 146.

ARECA (Areec is its name in Malabar, when an old tree). The Cabbage Palm. ORD. Palmeæ. This genus is now broken up into several, and many species formerly here arranged are now found under Acanthophœnix, Euterpe, Hyophorbe, Kentia, Oncosperma, Phænicophorum. Very ornamental and graceful stove palms, with a branching spadix, and double spathe, which incloses the flowers. Flowers unisexual, borne upon the same spike; female flowers having six rudimentary stamens, and male flowers a six-cleft perianth. Fruit one-seeded. They thrive in a compost of loam, peat, and leaf soil, in equal parts, with a liberal addition of sand; but when they are fully grown,[110] loam should preponderate to the extent of about two-thirds, and some rotten cow-manure may be added. Propagated from seeds, which should be sown in a compost similar to above, and placed in a moist gentle heat. They are employed, when young, with much success for the decoration of drawing rooms and dinner tables.

ARENARIA (from arena, sand; in which most of the species are found). Sandwort. ORD. Caryophyllaceæ. TRIBE Alsineæ. A very large genus of hardy herbaceous plants, consisting of about 150 species. It is distinguished by having generally three styles. The perennials only are worth growing; these are extremely pretty little alpine plants, and will thrive in any ordinary soil in exposed places; the rarer species may be grown in small pots, well drained, in a mixture of sand, loam, and leaf soil, or in well-drained crannies of the rockery. They may be increased by either division, seeds, or cuttings; the latter, placed under a hand-glass, will root freely. The best time to divide the plants is early spring, or July and August. Seeds should be sown in spring in a cold frame.

ARGANIA (from argam, its aboriginal name). ORD. Sapotaceæ. A very fine greenhouse evergreen tree, said by Don to flourish against a south wall, out of doors, with the protection of a mat in severe weather. It will thrive in ordinary garden soil. Increased by layers and cuttings in autumn and spring, the latter requiring a bell glass covering; both operations must be performed in a moderately heated greenhouse.

> A. Sideroxylon (Iron-wood). fl., corolla greenish yellow, cup-shaped, five-parted, with ovate-lanceolate, sub-emarginate segments; lateral and axillary, scattered, crowded, sessile. fr. dotted with white, size of a plum, full of white, milky juice. July. l. lanceolate, entire, bluntish, glabrous, paler beneath; branches terminated by strong spines. h. 15ft. to 20ft. Morocco, 1711.

ARGOLASIA. See Lanaria.

ARGIYREIA (from argyreios, silvery; in reference to the silvery undersides of the leaves). Silver-weed. ORD. Convolvulaceæ. An elegant genus of greenhouse and stove climbers. Sepals five; corolla campanulate. Shrubs for the most part silvery, but sometimes silky and tomentose. The greater number of the species are robust, extensive twiners or climbers, usually requiring plenty of room to run, before they will flower.

ARISTATE. Having a beard or awn, as the glumes of barley.

ARISTEA (from arista, a point or beard; in reference to the rigid points of the leaves). ORD. Iridaceæ. A genus of greenhouse herbaceous perennials from the Cape of Good Hope. Flowers blue; perianth rotate, six-parted, twisted after flowering; scape two-edged, rigid, often branched. Leaves narrow, sword-shaped. The species are more interesting than ornamental, and may be grown in a compost of three parts turfy peat, and one of loam. Easily propagated by divisions and seeds.

ARISTOLOCHIA (from aristos, best, and locheia, parturition; in reference to its supposed medicinal character). Birthwort. ORD. Aristolochiaceæ. A very large genus of stove, greenhouse, or hardy, evergreen or deciduous, climbing or erect shrubs. Flowers axillary, clustered, or solitary, pendulous, of most extraordinary forms; perianth tubular, curved, or straight, with an oblique, cordate limb; stamens six, rarely four, or numerous, adhering to the stigma; capsule six-valved. Leaves cordate entire or lobed. Good loam, with a small proportion of decayed manure and a slight addition of sharp sand to secure efficient drainage, is a good compost for the whole. They will thrive when planted out in the conservatory more satisfactorily than elsewhere; for as they usually grow a considerable height before flowering, they require very long trellises in pots, and have to be trained up and down; or, better still, round a pillar of uniform circumference, a pyramid form being useless. The best way is to train them round, close down to the pot, and keep on about 2in. from one turn to the next. Some of the larger sorts will require more room. Cuttings root freely in sand under a bell glass with bottom heat.

> A. anguicida (snake-killing). fl. white, spotted brown; tube of perianth inflated at base, dilated and oblique at the mouth; peduncles axillary, solitary, one-flowered. December. l. on short petioles, cordate acuminate; stipules cordate-roundish. h. 10ft. New Grenada, 1845. An evergreen stove twiner.

> A. barbata (bearded). fl. purple, axillary, 2½in. long; perianth straight; limb spreading; lip spathulate, bearded at the end. July. l. cordate, oblong. h. 10ft. Caraccas, 1796. Stove evergreen.

> A. Goldieana (Goldie's).* fl. greenish outside, deep yellow with chocolate veins inside, bent into two unequal portions, the lower portion surmounting the ovary about 8in. in length, somewhat cylindrical, terminating in a club-shaped curved knob; the upper portion, commencing from this knob, is about a foot long, funnel-shaped, ribbed, dilated above into a somewhat three-lobed limb. Stamens twenty-four—a very unusual number in the whole family. The enormous flowers are 26in. long by 11in. in diameter. July. l. ovate, or triangular-cordate, acuminated. Old Calabar River, 1867. This noble climber should be repotted in fresh soil in February or March. But little water will be necessary until the young shoots have made about 6in. of growth; the quantity should then be increased with moderation until early in September, when the old stem dies down within a few inches of the surface of the pot—at this period, and during winter, water must be entirely withheld. This species blooms freely in a temperature of 65deg. to 70deg.

> A. ornithocephala (bird's-head).* fl. purple, very large, and extremely singular. To render any description at all lucid, this species may be said to have the head of a hawk and the beak of a heron, with the wattles of a Spanish fowl, which, however, are grey, netted with brown; head of the same colour, veined; and the beak grey. l. between cordate and reniform, obtuse. October. h. 20ft. Brazil, 1838. Stove species.

ARMENIACA (from Armenia, the native country of the Apricot). Apricot. ORD. Rosaceæ. TRIBE Drupaceæ. Small, hardy, deciduous trees. Flowers appearing before the leaves from scaly buds, solitary, or few together, almost sessile. Leaves, when young, convolute. Drupe ovate-globose, fleshy, covered with velvety skin, containing a nut, or stone, which is acute at one end and blunt at the other, with a furrow on both sides; the rest smooth, not wrinkled. For culture, &c., see Apricot and Prunus.

> A. brigantiaca (Brigancon).* fl. white or pink, glomerate, almost sessile. March. l. somewhat cordate, acuminated, sharply toothed; the teeth numerous, and lapping over each other. h. 6ft. to 8ft. South Europe, 1819.

ARMERIA. (from Flos Armeriæ, Latin name for the flowers of a species of Pink). Thrift; Sea Pink. ORD. Plumbagineæ. A very interesting and pretty group of hardy alpine tufted perennials. Flowers pedicellate, collected in dense solitary heads; involucre scarious, sheathing the scape and turned downwards; petals cohering at the base, persistent; flower scapes leafless. Leaves linear, radical. As the majority of the species differ in mere technical details, we have given a representative group only. They are easily cultivated in a sandy loam and leaf soil, and are increased by seeds and division, separate pieces being planted as cuttings under hand glasses; or the rarer kinds should be potted and placed in a frame. The seed should be sown in spring, in pots of sandy soil, and placed in a cold frame. Although best grown as rock plants, most of them do well in pots and borders. A. vulgaris makes one of the best of edging plants.

Autumn. l. broadly lanceolate, glabrous, acute; petioles channelled, sheathing at the base. h. 12in. to 18in. South Europe, 1800. This is perhaps the finest species, and is best raised from an annual sowing of seed, as it is somewhat difficult to increase by divisions. SYNS. A. formosa, A. latifolia, A. mauritanica, and A. pseudo-armeria.

> A. dianthoides (Pink-like).* fl. light pink, in close heads about 6in. high. May and June. l. spreading, flattened, nerved, slightly downy. South Europe, 1810.

June to August. l. all radical, numerous, linear, usually one-nerved, more or less pubescent. h. 6in. to 12in. Britain, on the sea coasts. A. v. alpina is a dwarf alpine form of this species. The white-flowered variety is very handsome. A. v. Laucheana is also a pretty form, with deep pink flowers in dense heads about 6in. high, and a very tufted habit. Crimson Gem, of garden origin, is stronger growing, with stems about 9in. high, carrying heads of bright crimson pink flowers, also of tufted habit. SYNS. A. maritima, Statice Armeria.

ARNEBIA (its Arabian name). ORD. Boraginaceæ. Handsome hardy herbaceous perennials or annuals, allied to Lithospermum. Cuttings should be removed with a heel in autumn, dibbled in sandy soil in small pots, and placed in a cool house, where they will ultimately, though slowly, root; they should then be gradually hardened off, and finally planted out. A. echioides is also easily increased by making cuttings of the strong roots, which should be dibbled in pots of sandy soil, and placed in gentle heat; it is also raised from seed.

> A. echioides (Echium-like).* fl. bright primrose yellow, with a purplish spot in the sinuses between the lobes of the corolla, which gradually disappears in a few days; spikes terminal, large, solitary, secund. May. l. sessile, alternate; margins—as well as the stems—ciliated. h. 9in. to 12in. Armenia. One of the showiest of hardy perennials for the border or rockery.

> A. Griffithii (Griffith's). This differs from above in having narrower leaves, rather smaller flowers, which are of a more decided yellow, a differently shaped calyx, and a longer corolla. h. 9in. North-west India. Equally desirable, were it a perennial; but, being an annual, it must be constantly raised from seed.

ARNICA (from arnakis, lambskin; in reference to the texture of the leaves). ORD. Compositæ. Hardy, dwarf, herbaceous perennials, allied to Senecio. They thrive best in loam, peat, and sand; the plants are best divided in spring. Seeds should be procured when possible, and sown in a cold frame, in spring. The only species worth growing are described below.

ARPOPHYLLUM (from arpe, a scimitar, and phyllon, a leaf; the leaf is sword-shaped). ORD. Orchideæ. Distinct evergreen epiphytes. There are about six species known, and the genus belongs to the Epidendreæ division of orchidaceous plants; their general characters are: Flowers small, numerous, in closely packed cylindrical spikes; anther-bed broad, shorter than the broad extension of the upper edge of the stigma; pollinia eight. Stems rather long, with white sheaths. They thrive well in fibrous peat, one-third turfy loam, freely interspersed with lumps of fresh charcoal and an abundance of crocks. When growing, a liberal supply of water at the roots is essential, as is also a situation near the light, where they will blossom much more profusely than if in any way shaded. The flowers last in perfection about four weeks.

> A. spicatum (spike-flowered).* fl. dark red, on an upright spike about 1ft. long. During winter. Guatemala, 1839.

ARRACACHA (its Spanish name in South America). ORD. Umbelliferæ. A half-hardy tuberous perennial, highly esteemed as an esculent in South America, where it yields a food, which is prepared in the same manner as potatoes, and is said to be grateful to the palate and extremely easy of digestion. It thrives best in rich loam, and is increased by divisions of the roots.

ARTABOTRYS (from artao, to suspend or support, and botrys, grapes; in reference to the way the fruit is supported by the curious tendril). ORD. Anonaceæ. A handsome stove evergreen shrub, thriving in a good sandy loam and peat, to which a little rotten dung may be added. Propagated by cuttings made of ripened wood, insert in sand under a bell glass, with bottom heat, in early spring. Seed, when procurable, should be sown as soon after receipt as possible.

June and July. l. oblong-lanceolate, acuminated, smooth, shining. h. 6ft. Malayan Islands, 1758. In Java, the leaves are held to be invaluable as a preventive of cholera.

ARTANEMA (from artao, to support, and nema, a filament; in reference to a tooth-like process growing on the longer filaments). ORD. Scrophularineæ. An interesting and handsome greenhouse evergreen shrub, allied to Torenia. Flowers disposed in terminal racemes, and on short pedicels. Leaves opposite, sub-serrated. It may be treated as hardy during summer, for which purpose seeds should be sown in spring; but it requires the protection of a greenhouse during winter. Artanema grows freely in light rich soil, and is readily increased by cuttings and seeds.

> A. fimbriatum (fringed). fl., corolla blue, large, tubularly funnel-shaped, clothed with minute glandular pubescence outside; lobes unequally serrated; racemes terminal, four to sixteen-flowered. June, November. l. lanceolate, acute, serrated, rough to the touch from numerous elevated dots. Stem smooth, glossy. h. 2ft. to 3ft. New Holland (on the banks of the Brisbane River at Moreton Bay), 1830.

ARTHROTAXIS. See Athrotaxis.

ARTICHOKE, GLOBE. (Cynara Scolymus, a cultivated form of C. Cardunculus). As a vegetable, the Globe Artichoke is cultivated for the use of the immature flower-heads, and is highly esteemed. A good open position, free from overhanging trees, is best suited for its culture generally, but, by planting successional suckers in different aspects, the season may be considerably prolonged. The soil must be of good depth, rich, and not too heavy. It may be greatly improved for Artichoke culture by the addition of sea-weeds or salt applied as manure.

FIG. 151. GLOBE ARTICHOKE.

Preparation of Soil. Trench the ground two spits deep if possible, mixing a liberal dressing of well-rotted manure in autumn, and ridge up for the winter, to sweeten. Crude manure full of straw, leaves, and sticks, often induce fungoid growths, and are most injurious to the crowns of the plants. Clay or stiff loam is about the worst soil on which to attempt the culture of this vegetable; this drawback may, however, to some extent be alleviated by the addition and thorough amalgamation of a light free soil or liberal dressings of sandy road drifts, or similar materials. An ill-drained soil is also fatal to good results. During hot, dry weather, the plants are greatly benefited by copious applications of clear water and dilute liquid manure; and this must be especially attended to on such soils as are liable to burn or dry up in summer.

Cultivation. When the beds have been properly prepared, the plants should be put in them in April or May. Place three together in rows between 3ft. and 4ft. apart, and about 3ft. from plant to plant. Water-in carefully to settle the soil around the roots, and apply a mulching of half-decayed manure, to prevent an undue evaporation of moisture. During hot, dry weather, give liberal supplies of water, and the plants will become established as fine stools the first season. A few heads will probably be produced the first year; but there will not be much of a crop until the second season, when five or six good heads will be got from each plant, and for three or four years the produce will be large if the beds are properly attended to; after which time it will become desirable to make up new plantations. In October or November, it will be necessary to apply a good mulching of straw or fern to the beds, to protect the plants from frost. In April, all this litter should be cleaned off, a dressing of rotten manure applied, and the beds forked over and kept clean for the rest of the season, treating as before described. Great care must be taken to remove the heads as soon as they are in a fit state; and, when the whole of them are removed from the stems, cut the latter out as low as possible. Globe Artichokes will keep for some considerable time if laid in a cool place, although they will deteriorate in quality. These plants may be used in the background of flower borders in the kitchen garden, their handsome foliage being peculiarly well adapted for such purposes, whilst their economical value is also secured. See Fig. 151. Where there is plenty of room in light, warm sheds, orchard houses, or other places where frost can be kept out, some stools can be taken up with the root intact in the early part of November, placed in boxes of soil, and well watered-in. When drained, the boxes may be put in any of those positions for their winter quarters, and, if kept moist, will develop much earlier than the outdoor crops, provided they are planted out early in April on a warm border, and protected with mats when the weather is cold. Propagation may be effected by seeds, or by suckers from the old stools, the latter being the better plan. In the former case, sow the seeds in March, on a gentle hotbed, and prick the seedlings off singly, when large enough, into small pots. Harden off by the last week in May, and plant out in threes as previously recommended, protecting the plants from late frosts. During the growing season, give an abundance of water and liquid manure mulching, to prevent undue evaporation. In November, well cover with dry litter which will not heat; and, in hard frosts, or heavy snow, throw a few mats over the beds, uncovering at the same time as recommended above for the older plants. To propagate by rooted offsets or suckers, take up and divide the stools, when they have made a fair amount of growth in April or early in May, separating the suckers with as many roots and as much soil adhering to them as possible. The old woody portions are of little use, but they may be replanted to give off a fresh supply of suckers for the next year, if required. Propagation by suckers, if they are to be obtained, has many advantages; but care must be taken, in removing them from old plants, that some roots are attached, or growth will be uncertain. Seeds generally produce a large percentage of plants that are useless, and this is not found out until the flower-heads appear. On the other hand, suckers reproduce the parent plant, and if these are previously selected, the superior stock is thereby perpetuated.

Sorts. The Green and Purple are the best for ordinary purposes; and of these preference should be given to the former. See also Cynara.

ARTICHOKE, JERUSALEM (Helianthus tuberosus). A hardy tuberous-rooted herbaceous perennial, native of Brazil. The roots are used as a vegetable principally during the winter, sometimes as a dish, but more generally for flavouring purposes. Plants will grow in almost any position, but the best results and largest tubers are obtained where they receive plenty of room and liberal treatment. Their culture has been recommended as a substitute for the potato, but they are not likely to take the place of this vegetable, the flavour being disliked by many persons. A few are, however, generally acceptable.

Cultivation. To ensure the most successful results, trench over a piece of ground in autumn, and give a light dressing of manure. Fork over in March; at the[117] same time plant good-shaped tubers (see Fig. 152) in rows about 3ft. apart, and allow from 18in. to 2ft. between the tubers in the rows. Keep clear of weeds; and, as soon as the foliage is yellow, in the latter part of the autumn, the roots will be fit for use. The best plan with this crop is to leave it in the ground till wanted, or till the end of February, and then to take up every tuber, replanting those which are wanted for stock, and storing the others away in a cold dry place. When they commence growth, they turn black, and are of little use for cooking, save for flavouring soups. This vegetable has of late years grown into favour as a marketable crop, and the demand seems to be increasing. Considering its very easy culture, it is fairly remunerative. See also Helianthus.

ARTILLERY PLANT. See Pilea microphylla.

ARTOCARPEÆ. A tribe of the large order Urticaceæ.

ARTOCARPUS (from artos, bread, and carpos, fruit; the fruit, when baked, resembling bread). Bread Fruit. SYNS. Polyphema, Rademachia, Rima. ORD. Urticaceæ. TRIBE Artocarpeæ. Included in this most remarkable tribe, in addition to the Bread Fruit Tree, is the virulent poisonous Antiaris toxicaria, and the economic Cow Tree (Brosimum Galactodendron), of Caraccas. A genus of stove evergreen trees, requiring a high and very moist atmosphere, a copious supply of water, perfect drainage, and a compost of two parts rich loam and one of leaf mould, with the addition of a little silver sand. Under all conditions, this genus is difficult to propagate; the young and slender lateral growths are adapted for cuttings; and suckers may be utilised when procurable, which is very rare.

> A. Cannoni (Cannon's).* l. alternate, petiolate; petiole and midrib bright red; upper surface glossy, of a rich, full bronzy crimson hue, beautifully tinted with purple; under surface bright vinous red. The leaves vary much in form; some are simple and cordate at the base, with the apex irregularly lobate; some have the apex regularly three-lobed, with short, entire lobes; and others, again, are deep three-lobed, being divided nearly to the base, the segments, of which the centre one is largest, being slightly sinuate-lobed. h. 7ft. Society Islands, 1877. This is a most distinct and handsome ornamental-leaved plant.

> A. incisa (incised).* True Bread Fruit. l. from 2ft. to 3ft. long, deeply lobed or incised, deep green on the upper side, paler below. h. 50ft. South Sea Islands, 1793. This is a noble tree when full grown, and forms a most distinct and beautiful stove plant. The extraordinary fruit is produced from the axils of the leaves in large globular heads, and is highly valued as an article of food in its native country.

> A. integrifolia (entire-leaved). l. oblong, undivided, sinuated, scabrous, downy beneath. h. 30ft. India, 1778.

> A. laciniata metallica (laciniate, metallic). l. bronzy above, reddish purple beneath. Polynesia.

FIG. 153. ARUM MACULATUM.

ARUM (formerly aron, and probably of Egyptian extraction). ORD. Aroideæ. A large genus of ornamental or curious, hardy, greenhouse or stove perennials, with thick rhizomes and pedate or hastate leaves. Spathe large, convolute; spadix naked and club-shaped at the top. They are all of easy culture, and the indoor species will thrive with such treatment as is given to Alocasias, Caladiums, &c. Rich soil is one of the first conditions of success. Like most plants grown for the beauty of their foliage, rapid and free growth is necessary. A compost of good rich loam, with a third of sweet manure, thoroughly rotted, or leaf mould, with some sharp sand, is very suitable. Plenty of moisture is necessary during[118] the growing season, after which the tender kinds should be kept moderately dry, warm, and at rest during the winter. The hardy kinds may be left in the ground. Propagated by seeds or division of the roots—usually the latter. The best time to divide them is just as they commence their new growth, securing as many roots as possible to each division. Any rootless pieces should be placed in heat shortly after removal; this hastens the formation of roots and excites top growth. Arums are useful in sub-tropical gardening, and are otherwise interesting plants both for indoors and outside cultivation; and the hardy kinds are very suitable for naturalising in woodlands, &c. There are many other species besides those here described, but the following list comprises the best. Sub-sections of the genus will be found treated separately, such as Amorphophallus (which see), &c.

FIG. 154. ARUM DRACUNCULUS.

> A. bulbosum (bulbous). Synonymous with A. ternatum.

ARUM LILY. See Richardia æthiopica.

ARUNDINARIA (altered from arundo, a reed). ORD. Gramineæ. A small genus of hardy or nearly hardy shrubby grasses, having strong jointed stems, and frequently included under Bambusa. For sub-tropical gardening purposes more particularly it is exceedingly ornamental as an isolated tuft. It thrives best in a deep, rich soil, and requires plenty of water when in a growing state. Increased by division of the roots.

FIG. 155. ARUNDINARIA FALCATA.

> A. falcata (sickle-shaped).* l. linear-lanceolate, very acute, shortly stalked, very light green. Stems freely branched, deep green, and very slender. h. 3ft. to 6ft. India. An extremely handsome species for greenhouse decoration; also for outdoor work, particularly in the South of England, &c. SYN. Bambusa gracilis, of gardens.

> A. Maximowiczii (Maximowicz's). This Japanese species is believed to be allied to, if not identical with, Bambusa Simonii. Quite hardy.

> A. Metake (Metake). l. lanceolate, with very sharp points, dark green, persistent, narrowed into a short leafstalk, 6in. to 12in. long; sheath ample. h. 4ft. to 6ft. Japan. A handsome, hardy, dwarf, much-branched species, forming grand specimens, and producing flowers very freely. SYN. Bambusa japonica.

ARUNDO (origin of word doubtful; stated by some authorities to be from arundo, a reed; and others as from the Celtic arn, signifying water). Reed. ORD. Gramineæ. A very ornamental group of half or quite hardy plants, of very easy culture in ordinary garden soil, preferring damp situations. Panicle loose; calyx two-valved, unequal, many-flowered; corolla of two very unequal valves; all, except the lower and imperfect one, surrounded by a tuft of hairs. Fruit free, covered by the corolla. Arundos are very valuable either for conservatory decoration, sub*-tropical gardening, or cultivation in clumps on the turf of the flower-garden or pleasure ground, and the margins of lakes. Although well worth growing, all are inferior to their ally, the Pampas Grass. Propagated by seeds or divisions, the spring being the best time to adopt either method of increase.

> A. conspicua (conspicuous).* fl. silky-white, on large drooping racemes, and lasting in beauty for several months. h. 3ft. to 8ft., but in a good deep and sandy loam it sometimes attains the height of 12ft. New Zealand, 1843. This fine species grows in dense tufts, from which arise numerous leathery, narrow, smooth (or slightly rough), long curving leaves, and erect, slender culms. The plant is not sufficiently hardy to withstand a severe winter, and should, therefore, be protected with mats, or be grown in tubs, so that it can be removed under shelter before the approach of winter. These precautions are unnecessary in the more southern counties of England.

> A. Donax (Donax).* Great Reed. fl. reddish, ultimately whitish, in numerous spikelets, forming a large compact panicle 12in. to 16in. long. Autumn. l. alternate, lanceolate-acute, large, and ornamental, glaucous green, arching. h. about 12ft. South Europe, 1648. This also requires protection during winter in the colder counties. See Fig. 156.

> A. D. versicolor (various-coloured).* h. 3ft. South Europe. Although much smaller, this variety is far superior to the type for gardening purposes, and has its leaves ribboned with white. It requires a deep, well drained, sandy loam to thrive well, and a thorough winter protection of cocoa-fibre refuse or coal ashes. For isolated tufts or groups, few plants can equal it. It is propagated by placing a stem in water, which induces little rooted plants to start from the joints; these should be separated, potted off, and kept in frames until thoroughly established.

> A. mauritanica (Mediterranean Reed). This is a rare greenhouse species, closely allied to A. Donax, but inferior to it.

ASCLEPIADEÆ. A large order of, for the most part, lactescent, climbing shrubs. Flowers sub-umbellate, fascicled or racemose, interpetiolar; pollen collected in the form of waxy masses, coalescing to the cells of the anthers; follicles two, one of which is abortive. Leaves entire, usually opposite.

ASCLEPIAS (the Greek name of Æsculapius of the Latins). Swallow-wort. ORD. Asclepiadeæ. Erect, hardy, herbaceous or sub-shrubby perennials, except where otherwise specified. Corolla five-parted, reflexed; umbels interpetiolar; corona seated on the upper part of the tube of the filaments, five-leaved. Leaves opposite, verticillate, sometimes alternate. Most of the hardy species are very handsome border plants, thriving in peaty, or light rich soil, and are increased by dividing the roots in spring, and sometimes also by seeds. The doubtfully hardy or rarer species should always be grown in a peat soil, and have a little protection during severe frost, by mulching the roots. The most important of the greenhouse and stove species is A. curassavica. In order to obtain good bushy specimens of this, it will be necessary to cut the plants back annually, after keeping them slightly dry, and resting for a month or two in midwinter. When growth has sufficiently advanced, they should be shaken out and repotted. At this stage, a close, moist atmosphere will be needful to produce the usually very free growth. The points of the shoots must be nipped out, in order to promote a bushy habit. When the pots have become filled with roots, liquid manure may be applied; but it must be quite clear and not over strong. All the indoor species grow best in good fibry loam and leaf mould, and require to be potted firmly. Cuttings should be secured in spring, struck in gentle heat, under a bell glass, and as soon as they are well rooted, potted into 60-size pots. A shift must be given as often as the pots become filled with roots, up to the time when the plant commences flowering. Seeds may be sown in pots in spring, pricked out singly when large enough, and then treated similarly to cuttings.

ASCYRON. See Hypericum Ascyron.

ASCYRUM (from a, without, and skyros, hard; that is to say, a plant which is soft to the touch). ORD. Hypericinæ. A genus of elegant little herbs and sub-shrubs, with sessile, entire leaves, destitute of pellucid dots, but usually furnished with black dots beneath. Flowers resembling Hypericum. They require to be protected during winter by a frame; for this purpose they should be grown in pots, as they never exist long in the open border. A compost of peat, pure leaf soil, and sand, in equal portions, suits them well; young cuttings of the shrubby kinds will root in sand under a hand bell glass. Propagated by careful divisions of the roots in spring. All may be raised from seeds.

> A. hypericoides (Hypericum-like). fl. yellow. August. l. linear-oblong, obtuse. h. 2ft. North America, 1759.

> A. stans (standing). St. Peter's Wort. fl. yellow. August. l. oval or oblong, somewhat clasping. h. 2ft. North America, 1816.

ASHES. The earthy or mineral particles of combustible substances, remaining after combustion. Ashes are amongst the most economical manures.

Vegetable Ashes are generally the best application for manuring boggy, cold, and, consequently, sour and unprofitable land, in quantities of about forty bushels per acre, thinly and evenly distributed. The annual exhaustion of salts from large crops of grain, roots, and grass, is from 180lb. to more than 250lb. per acre; and the aggregate of a few years will so far impoverish the soil in one or more of the principles necessary to sustain a luxuriant vegetation, that it will cease to yield remunerating returns. The ashes of vegetables consist of such elements as are always required for their perfect maturity, and it is evident they must furnish one of the best saline manures which can be supplied for their growth; they contain, in fact, every element, and generally in the right proportions, for insuring a full and rapid growth. Both gardener and farmer will therefore perceive the great value of Ashes to their crops.

Coal Ashes. The bituminous and anthracite coals afford Ashes, and, although inferior in quality to those made from wood and vegetables, are, like them, a valuable manure, and they should be applied to the land in a similar manner. If they contain many cinders, from not having been thoroughly[121] burned, they are more suited to heavy than to light soils. Coal Ashes, if very fine, may be sprinkled half an inch deep on the surface, over peas and beans, &c., to preserve them from mice; they may also be used for garden and greenhouse walks, where bricks or tiles are absent, being tidy in appearance, and an excellent substitute for other and more expensive material.

Peat Ashes. Peat approaching to purity, when thrown out of its bed and thoroughly dried, may be burned to an imperfect Ash, and when it does not reach this point, it will become thoroughly charred, and reduced to cinders. The process of burning should be as slow as possible. In either form, it is a valuable dressing for the soil.

ASH-TREE. See Fraxinus.

ASIATIC POISON BULB. See Crinum asiaticum.

ASIMINA (meaning unknown). ORD. Anonaceæ. Hardy shrubs, with oblong, cuneated, usually deciduous leaves. Flowers sometimes rising before the leaves, usually solitary and axillary. They thrive freely in a mixture of sand and peat. Propagated by layers put down in the autumn, or by seed, procured from their native country. Seedlings should be raised in pots, and sheltered in winter, until they have acquired a considerable size.

FIG. 159. FLOWERING BRANCH OF ASIMINA TRILOBA.

> A. triloba (three-lobed).* fl. campanulate, the three outer petals pale purplish, and the three inner ones smaller, purplish on the outside as well as the inside at the base and apex, with the middle yellow, about 2in. diameter, produced between the upper leaves. May. l. oblong-cuneated, often acuminated, and, as well as the branches, smoothish. h. 10ft. Pennsylvania, 1736. A small tree or shrub. See Fig. 159.

ASKALLON (the Eschallot). See Allium ascalonicum.

ASPALATHUS (from a, not, and spao, to extract; in reference to the difficulty of extracting its thorns from a wound). Including Sarcophyllus. ORD. Leguminosæ. Shrubs or sub-shrubs, natives, with one exception, of the Cape of Good Hope. Flowers usually yellow, furnished with three bracteoles, or a leaf comprised of three leaflets. Leaves of three to five leaflets, disposed palmately, rarely pinnately, having scarcely any or very short petioles. All the species are pretty when in flower, and thrive in a mixture of loam, peat, and sand. Young cuttings of half-ripened wood will strike in April, in sand, under bell glasses, which must be wiped dry occasionally. But little water is needed. Over a hundred species are known; those introduced are very rarely seen in cultivation.

ASPARAGUS (from a, intensive, and sparasso, to tear; in reference to the strong prickles of some species). ORD. Liliaceæ. Erect or climbing herbs or shrubs, with very small scale-like leaves, and a profusion of numerous slender fascicled-needle, rather spiny branchlets. Flowers axillary, inconspicuous. Fruit baccate. The indoor species will all thrive well in a warm greenhouse temperature, provided they have partial shade, a good supply of moisture at the roots, and are not kept too close, in a moderately rich sandy compost. The hardy species are propagated chiefly by seeds and divisions of the roots. Rich sandy loam is necessary, and otherwise they may be treated as ordinary perennials. Some of the species belonging to this genus are among the most elegant of foliage plants for cutting purposes. A. decumbens and A. scandens make excellent plants for Wardian cases, and may be cut in freely if they exceed their limits.

ASPARAGUS (A. officinalis) AS A VEGETABLE. The value and importance of this plant as a vegetable cannot be over-estimated; it is extensively grown, and, when properly managed, produces a fairly lucrative crop.

Soil and Bed. The first thing to be done in the preparation of an Asparagus bed to stand for any length of time, is to secure an efficient drainage; and on wet soils this is best effected by placing a layer of brick rubbish over the whole of the bottom, and connecting this with a drain. On gravelly or other soils which are drained naturally, of course, this is not needed; but if really good crops are a desideratum, water should not stand within 3ft. of the surface. In all cases, the ground must be dug to a depth of 18in., and, if stiff, a goodly amount of road sweepings, or other gritty materials, should be well mixed with the staple soil. Asparagus requires a good soil, neither too heavy nor too light.

Manuring. After the soil has been well trenched, and has lain long enough to settle down, a good dressing of manure—thoroughly rotted, and not too rank, at the rate of from twenty to thirty tons to the acre, dug into the surface of the beds—will be found very beneficial. If possible, this should be introduced in January; and then, if the weather permits, the beds should be forked two or three times by the end of March, so as to render the soil as friable as possible. A very good manure, and one that is easily obtained, is common garden salt. This may be given annually to established beds. A moderate dressing should be applied just before growth commences in spring, but a little will do no harm at other times during the summer. It is best scattered on with the hand, and a showery day should be selected, as it will then soon disappear. Salt, besides acting as a manure, has also the properties of keeping the beds cool and moist in hot weather, and of preventing the growth of weeds.

Planting. Asparagus can be planted during March and April, the latter month being the best time for the work. The soil having been thoroughly prepared, the next point is to decide on the size of the beds; this[122] depends on the size of garden, and the class of "grass" desired. When very large and fine stocks are the object in view, the best results will accrue if the plants are fully a yard apart each way; but this means a comparatively small crop. A good plan is to make the beds 3ft. wide, planting two rows, at a distance of 1ft. from each other, and allowing 18in. between each plant, placing them in alternate order. An 18in. alley should be allowed between the beds. The roots used for making the beds should be one year old, and fresh from the ground. In planting, pull out a wide drill with a hoe, or other tool, to the depth of about 3in. or 4in., and spread out the roots all round. Carefully shake the soil in amongst the roots, and, if dry, apply some water through a coarse-rosed watering pot, to settle the earth around them. At intervals, as necessary, give other waterings till September, when they should be discontinued. At all times, keep the beds free from weeds, removing them by the hand to prevent injury to the crowns of the plants. If the ground is good, no liquid manure will be needed the first year. As soon as the foliage turns yellow, cut it off, cleanly rake over the beds, and leave till about January, when a top-dressing of from 1in. to 3in. of thoroughly rotted manure may be applied with advantage. At the end of February, rake off the bed all loose straw or other debris, and throw on them a little of the soil from the alleys, raking down, and finishing off the edges squarely and neatly. During this and succeeding years, apply liquid manure and clear water, from time to time, as required; and, provided the manure is not of too great strength, there is scarcely any limit to its application; but, in many instances, beds which have only received an annual dressing have given a good return. Each year they must be cut over and dressed as before described, but care must be taken to keep them flat on the surface, otherwise the plants will die out for want of moisture. When the produce appears, the beds should be kept cut over until the 20th of June, after which, cutting should cease, or they will be rendered comparatively unproductive. Cutting can commence the second or third year, or as soon as there is any "grass" worth taking. Several methods of growing these plants could be cited, but that which we have recommended will be found most satisfactory.

FIG. 160. ASPARAGUS, Crown for Lifting.

Seeds. Plants are raised by sowing seeds in rows across the kitchen garden, or selected quarter, about the month of April. The seedlings make a growth, and form good plants during the first season. In March or April of the following year, or the year after, they may be removed, and planted out permanently, as already alluded to. Many cultivators prefer growing their own plants from seed; because during the transit of the roots from any distance to where they are to be grown, a frequent and injurious exhaustion takes place, and particularly so when they are carelessly packed.

Forcing. Asparagus can, if properly treated, be obtained from December onwards; and at Christmas time the produce is very valuable; but, in order to obtain it at this season, it will be necessary to resort to forcing. Prepare some beds to secure a lasting heat, and on these place about 3in. of ordinary garden soil, not very stiff. Then take the roots, and place them crown upwards, and moderately close together, shaking the soil well amongst the roots, and covering about a couple of inches deep. Water well, to settle the whole, and put on the lights, allowing a little ventilation, to let out any steam which may arise. Unless the weather be very cold indeed, give a little air at all times, and only cover the lights in actual frost. From time to time, apply fresh linings of hot manure, and in cold rains, or wind, cover the outsides of the frames with old sacks, or other things which will keep in the heat. A regular and steady temperature of 60deg. will force this plant with better results than a higher one. Houses that are fitted with hot-water pipes to give bottom heat can be used equally as well as manure beds, and so long as the soil is kept moist, the heat thus obtained is as good as any for the purpose, and much less trouble than fermenting materials. To keep up a regular supply, a succession of beds will be necessary. Asparagus can be forced, or rather forwarded, in pots or boxes, in a warm greenhouse or vinery, and, of course, when the plants are done with, they can be cast away. We give an illustration (Fig. 160) of a bearing crown fit for gentle forcing; but, of course, it must not be left so bare of earth as appears here, which is done for the purpose of clearness.

Varieties. Connover's Colossal, and Giant, are the most esteemed. Strains are frequently largely advertised as improvements on the sorts above-mentioned, and the charges are higher accordingly. The difference may be generally attributed to the culture the plants receive more than to an improved variety. When saving seed for home sowing, they should be taken from the strongest growths, or deterioration will ensue.

> A. æthiopicus ternifolius (ternate). fl. white, in shortly-stalked racemes, very profuse. August. l., false ones in threes, flattened, narrow, linear; prickles solitary, reversed; branches angular. h. 30ft. South Africa, 1872. A greenhouse evergreen.

An elegant climbing greenhouse perennial.

> A. virgatus (twiggy).* A remarkably elegant feathery looking plant, of shrubby habit. The stems, which issue from the crown of the stout fleshy roots, are of a dark green colour, and bear at the upper end a corymbose head of erect branches, of which the lowest is the youngest or most recently developed. These branches are again twice branched, the ultimate branchlets being furnished with needle-shaped false leaves, ½in. long, which usually grow in threes. South Africa, 1862.

ASPARAGUS BEETLE (Crioceris asparagi), or "Cross-bearer." This beautiful little insect is blue-black or greenish; the thorax is red with two black spots, and the wing-cases are yellow, with a black cross on them; the legs and antennæ are black. The short grey larva is flat underneath, arched on the back, and covered with hairs. The sides are of an olive hue, and the little legs and head are black. It ejects a drop of blackish fluid from the mouth when touched. When full grown, which takes about a fortnight, the larva measures about two lines in length; the average length of the perfect Beetle is about three lines. Although this insect does not actually destroy the plants, it inflicts much damage on the foliage, and checks the growth of the stems after they have attained some size, in consequence of which the foliage becomes much less in the next season. The eggs are fixed to the shoots, and are small, dark, pointed bodies. The larvæ do the harm, as they feed on the bark and tender portions of the plants. The mature Beetles should be picked off by hand, and, by commencing early enough in the season, their numbers will be greatly reduced. Syringing the plants with water, heated to a temperature that will not injure the plants, is found a useful method for removing the grubs.

White Hellebore. Freshly-ground White Hellebore, sprinkled over the foliage while it is damp, and repeating the operation at intervals of about eight days for a season, will generally effect a riddance; but the following will usually be found better in such cases. Neither must be applied until after cutting ceases, as they are very poisonous.

Paris Green. This, mixed and used as for Cherry Fly (see Black Fly), will generally got rid of the Beetle, if applied about thrice each season for two years. It should, however, only be used in severe cases.

Soot, applied in the same manner as White Hellebore, and in liberal quantities, will, in a season or two, clear the beds. If a bushel of salt be mixed with each twenty bushels of soot, it will enhance the effect.

ASPARAGUS KNIFE. The Asparagus Knife consists of a strong blade fixed in a handle. There are, or were, three kinds employed: In one form, the blade was blunt on both sides, straight, with a sharp tip, and not unlike a small chisel. Another had its blade slightly hooked, and serrated at one end. But the best is that now almost universally employed, and which is illustrated by Fig. 162.

ASPASIA (from aspazomai, I embrace; the column embraced by the labellum). ORD. Orchidaceæ. A genus of elegant stove Epidendrum-like epiphytal orchids, with the lip united to the column, and broad, thin pseudo-bulbs. The name Aspasia is now and then met with attached to a totally different genus. Salisbury gave it to a liliaceous plant which is now referred to Ornithogalum. For culture and propagation, see Stanhopea.

ASPERULA (from asper, rough; in allusion to the leaves). Woodruff. ORD. Rubiaceæ. Hardy herbs, rarely small shrubs. Flowers terminal and axillary, in fascicles. Leaves opposite, with one, two, or three stipulas on each side; they are therefore called four to eight in a whorl, but between the uppermost leaves there are no stipulas. Stems and branches usually tetragonal. Most of the species are very pretty when in flower, and are, therefore, well adapted for borders, rockwork, and shady places, in almost any garden soil. Propagated by divisions of the roots during spring and early summer. Herbaceous perennials, except where otherwise stated.

ASPHALT. Artificial Asphalt is now generally used in England for footpaths, &c. The recipes are various, one of the best being the following: Lime rubbish two parts, coal ashes one part (both must be very dry), sifted very fine; mix them, and leave a hole in the middle of the heap, wherein pour boiling hot coal tar; mix well together. When as stiff as mortar, lay it down, 3in. thick, on a dry and previously well-levelled surface. A boy should follow with dry, finely-sifted sand, distributing just enough to prevent his boots sticking to the tar. Two men should be employed for the tarring, whilst another should attend to the boiling operation. Only just enough tar to last ten minutes must be taken from the furnace at one time, as, if it be not boiling, the walks will become soft under the action of very hot sun. This may be repeated every three years. It is imperative that the surface, lime, coal ashes and sand be perfectly dry, and that the days selected for the operation be very fine, the hotter the better. Another excellent plan is that of using gas lime and coal ashes. There must be a firm foundation and smooth surface. Spread the gas lime to about 1½in. deep, and level with the back of a spade. Over this place a thin layer of coal dust, and well roll. The work is then complete.

The annuals (Callistemma hortensis), usually known as French, German, or China Asters, are very extensively grown, both for beds and pots, and their diversity and generally compact growth render them almost universal favourites. They require a rich loamy soil, and as the roots are produced near the surface, a mulching of rotten dung will be found most beneficial. Seeds may be raised in a cold frame in March or April, and, when the seedlings are large enough, they must be transplanted into beds from 9in. to 12in. apart each way. If it is desired to have them in pots, they may be removed thence with a good ball of earth adhering just before they commence flowering, liberally watered, and kept lightly shaded from the sun, until root action is resumed. Those kinds required for exhibition purposes should have several of the side shoots removed, so that the whole growing energy of the plant may be centralised into from five to seven flower-heads, by which means fine blooms may be obtained. The dwarf kinds are most valuable for bedding and pots, as the taller kinds frequently require stakes for support. The following are the most important sections:

> Betteridge's Prize. Very beautifully formed and brilliantly coloured varieties, unsurpassed for exhibition purposes. As this class has rather a straggling habit of growth, it is less suitable for bedding and borders than many of the others.

> Boltze's Miniature Bouquet Pyramidal. Dwarf and elegant, in compact bouquets of six or eight; the truss of flower-heads springs directly from the ground, having only a few leaves at base. Colours very varied. h. 6in. to 8in.

FIG. 183. TRUFFAUT'S PEONY-FLOWERED ASTER.

FIG. 184. TRUFFAUT'S PERFECTION ASTER.

> Crown.* Distinct. The central portion, or disk, of the head of flowers is pure white, surrounded by a broad margin of coloured ray florets, such as purple, violet, crimson, rose, &c. Flower-heads large, flat, freely produced. h. 1ft. to 1½ft.

> Dwarf Chrysanthemum-flowered.* In size of flower-heads and habit of growth, this surpasses all other dwarf varieties. The flowers are full, Chrysanthemum-shaped, produced in clusters, or bouquets, from ten to twenty in a truss, very delicate and beautiful in colour. h. 1ft.

> Dwarf Pyramidal or Dwarf Bouquet. A pretty little class, and extremely floriferous, each plant producing from twenty to fifty heads of bloom. Some of the colours are: Exquisite carmine with white points, white with blue or carmine points, white with salmon centre, &c. h. 1ft.

> Improved Imbricate. The best strain of pyramidal Asters with recurved florets; fine regular form of flowers, double to the centre, producing but few seeds. Colours very brilliant. h. 2ft.

> Improved Rose. A handsome class, producing a branched head, displaying no less than fifty large double flower-heads, the outer[140] florets finely imbricated, and filled up to the centre when quite open. The colours are of great brilliancy, and of many shades. h. 2ft.

> Pompone Goliath.* Flower-heads globular, and florets very closely set. Valuable for bouquets, as the flowers remain intact for a considerable time.

> Pyramidal Hedgehog. Singular and unique. Stems upright, and branched; each branch terminated by a single flower-head, which is filled up with quill-like florets. Colours various. h. 1½ft.

> Truffaut's Pæony Perfection.* Vigorous upright growers, having large, hemispherical-formed heads of flowers with incurved florets, 4in. across. The colours also are very varied. h. about 2ft. See Figs. 183 and 184.

ASTERACANTHA (from aster, a star, and acantha, a spine; referring to the disposition of the spines). ORD. Acanthaceæ. A handsome greenhouse herbaceous perennial, of easy culture in sandy loam. It should be grown in a sunny position, and be kept moderately dry, otherwise little but foliaceous growth will be produced; but, if thus treated, it flowers freely. Propagated by divisions in spring; or by seeds, sown in August.

> A. longifolia (long-leaved). fl. yellow, in dense axillary fascicles. July. l. lanceolate, tapering to the base, narrow, sessile, serrately ciliated. Stem quadrangular. Plant rather hairy. h. 2ft. India, 1781.

ASTERACEÆ. See Compositæ.

ASTEROCEPHALUS. See Scabiosa.

ASTILBE (from a, without, and stilbe, brilliancy; in allusion to the inconspicuous flowers of some of the species). ORD. Saxifragaceæ. Tall branching herbs, with triternate or biternate leaves, allied to Spiræa, from which they differ in having not more than three carpels, eight or ten stamens, and numerous albuminous seeds. They are all more or less graceful, and some indispensable, either when grown in isolated clumps, or intermingled with other herbaceous plants. They thrive well in almost any rich garden soil, preferring damp positions, and are easily propagated by division, which is best done in early spring. A. japonica is grown very extensively for decorative purposes, its elegant spikes of pure white flowers rendering it especially valuable. The majority of the plants cultivated are imported, but they may be grown fairly well in this country in heavily manured soil. They should be potted as early as possible in the autumn, and plunged in ashes or fibre outside, when they will soon commence to root, after which they may be placed in heat, and forced as required, always giving an abundance of water. Indeed, the pots may be stood in pans of water, especially when the plants are well furnished with growth.

> A. barbata (bearded). A synonym of A. japonica.

> A. decandra (ten-stamened). fl. white, in spicate racemose panicles. May. l. biternate; leaflets cordate, deeply lobed and serrated, glandular beneath, and on the petioles. h. 2ft. to 3ft. North America, 1812.

> A. japonica (Japanese).* fl. small, pure white, in large branching racemose panicles. May. l. triternate or pinnate, serrated. h. 1ft. to 2ft. Japan. This is best grown in pots, as early frosts generally cut it down in the open air. SYNS. Spiræa barbata and japonica, also Hoteia and A. barbata. See Fig 186.

> A. j. variegata (variegated).* l. prettily variegated with yellow; panicles much more dense than the type; indeed, it is far superior in that respect.

FIG. 187. ASTILBE RIVULARIS.

> A. rivularis (brook).* fl. yellowish-white, or reddish, in large panicled spikes. Late summer. l. biternate; leaflets ovate, doubly serrated, villous beneath and on the petioles. h. 3ft. Nepaul. A grand plant for the margins of lakes or damp woodlands. See Fig. 187.

> A. rubra (red).* fl. rose, very numerous, in dense panicles. Late summer and autumn. l. biternate; leaflets oblique, cordate, 1in. to 2in. long, with elongated, serrated points. h. 4ft. to 6ft. India, 1851. A very pretty, but rare species; excellent for sub-tropical gardening.

> [141]

> A. Thunbergi (Thunberg's).* fl. small, white, very numerous, in erect, much branched, pyramidal panicles, with reddish and slightly downy stalks. May. l. unequally pinnate or bipinnate; leaflets broad, yellowish green, sharply toothed. h. 1½ft. Japan, 1878. This pretty little sub-shrub is extensively propagated on the Continent for forcing purposes.

ASTRAGALUS (a name applied to a shrub by Greek writers). Milk Vetch. ORD. Leguminosæ. A very large genus of hardy herbs or sub-shrubs. Flowers in axillary clusters; standard larger than the wings. Leaves unequally pinnate. About one hundred species have from time to time been introduced in English gardens; many of these are lost to cultivation; the comparative few here described are still generally grown, and are good representative species. They are all of easy culture. The shrubby kinds grow well in any light dry soil, and are slowly increased by cuttings placed in a cold frame, or by seeds. The herbaceous perennials prefer a dry light soil, and may be increased by divisions or seeds; the latter mode is preferable, as many species are very liable to die if transplanted or divided, which is at best but a slow method. Seed should be sown in pots of sandy soil placed in a cold frame as soon as ripe, or very early in the spring, as they may lie a long time before germinating. The dwarfer species constitute admirable rockwork plants, and can be grown in pots containing a mixture of loam, peat, and sand. Seeds of the two annual species, A. Cicer and A. Glaux, merely require to be sown in the open border early in spring.

> A. selaginoides (Selago-like). l. glossy green, scale-like, spirally disposed, closely appressed to the shoots, branches and their ramifications very numerous. h. variable, up to 40ft. Very interesting, and quite distinct. SYN. A. imbricata (of gardens).

ATHYRIUM. See Asplenium.

ATRAGENE (a name originally given to Clematis Vitalba by Theophrastus). ORD. Ranunculaceæ. A genus of ornamental, hardy, climbing, deciduous shrubs, closely allied to Clematis, from which they differ in having numerous petals. They are increased by cuttings, which should be pricked in light sandy soil and placed under a hand glass; also by layering in the autumn. Both methods are slow; the layers should not be separated for about a year, when they will be vigorous plants. Seeds must be sown in early spring, in gentle heat; when the seedlings are large enough to handle, they should be pricked off and grown on in pots till they are strong plants.

FIG. 189. ATRAGENE ALPINA, showing Habit, Twining Leafstalk, and Flower.

> A. alpina (alpine).* fl. blue, varying to white; petals ten to twelve, linear at the base, but dilated at the apex; peduncles one-flowered, longer than the leaves. May. l. biternate; leaflets ovate-lanceolate, acuminated, serrate. Mountainous parts of Europe, 1792. The white-flowered variety, named alba, is in cultivation. SYNS. A. austriaca and A. sibirica.

ATRIPLEX (from a, not, and traphein, to nourish). Orach. ORD. Chenopodiaceæ. A genus of, for the most part, uninteresting weeds, of very variable form and habit, and having the calyx, which encloses the fruit, enlarging after flowering. For culture, see Orach.

> A. hortensis (garden). An annual species from Tartary, of no value as an ornamental plant, but considered a very desirable substitute for spinach. The leaves must be gathered for use when young. The variety A. h. atro-sanguinea is a very pretty form, having handsome crimson leaves, and growing to a height of about 4ft. It is well worth growing with such plants as Amaranthus, &c.

ATROPA (name of mythological origin). Belladonna; Dwale. ORD. Solanaceæ. A small genus, having a campanulate regular corolla, and a leafy persistent calyx. The berries of this native herbaceous perennial are exceedingly poisonous. The plant is of no horticultural value.

ATTALEA (from attalus, magnificent; referring to the beauty of the genus). ORD. Palmaceæ. A genus of handsome stove palm trees, distinguished from other genera in having the pinnæ arranged vertically, and not horizontally. The leaves spring up almost perpendicularly at the base, but in the upper part arch over. The pinnæ stand at right angles to the rachis—which is very narrow in proportion to its thickness—and while those of the lower side of the arch hang straight down, those of the upper side point straight up. They thrive well in a mixture of peat and loam in equal quantities, and enjoy a copious supply of water. Summer temperature, 65deg. to 80deg.; winter, 55deg. to 60deg. All the species are robust trees; but, although several have been introduced, few appear to be generally grown.

> A. amygdalina (Almond-fruited).* l. pinnate, 3ft. to 6ft. long; pinnæ 12in. to 18in. long, and about 1in. broad; terminal lobe broad and bifid, rich dark green. Stem slender. New Grenada. One of the best. SYN. A. nucifera.

FIG. 191. FRUITING BRANCH OF ROUND AUBERGINE.

FIG. 192. FRUITING BRANCH
OF LONG AUBERGINE.

AUBERGINE, or EGG PLANT (Solanum melongena, variety ovigerum). These plants, besides being useful for culinary purposes, are very ornamental, and present an attractive appearance on walls or trellises, or in the flower garden; and, as they do well in any ordinary rich garden soil, if the position is warm, they give a good variation to the general run of plants used for decorative effects. The Black-fruited kind is particularly suited for this purpose. Sow the seeds in a gentle heat, in the middle of April. As soon as the seedlings are large enough to handle, prick off into 4in. pots, replacing in heat till they root out freely. Gradually harden off by June, and then transfer to the positions where they are to grow. Let the plants be at least 2ft. apart, and place a strong stick to each one to support the fruit when it comes. For trellises, select the more moderate-sized varieties. In hot, dry weather, the application of liberal supplies of liquid manure tends to increase the size of the fruit, and also to make the foliage more vigorous and handsome. Where very large fruit are needed for show or other purposes, it is well to remove all but the best one on the plant, and, by careful feeding with liquid manure, specimens of from 10lb. to 12lb. weight can be had. The foliage should not be pinched, as this would prevent the free swelling of the fruit. Aubergines are not so much grown in England for culinary purposes as in France and Italy, where they are largely used in stews and soups. The following are the most desirable varieties: New York Purple, the largest kind grown, and although not as ornamental as the next, is quite as useful; Black-fruited, large black fruit, with blackish violet leaves; and White-fruited, the sort most generally cultivated. See Figs. 191 and 192.

[145]

AUBRIETIA (named after M. Aubriet, a famous French botanical draughtsman). ORD. Cruciferæ. A small genus of hardy evergreen trailers. Racemes opposite the leaves, and terminal, lax, few-flowered. Leaves ovate or oblong, entire or angularly toothed, hairy. They make excellent rock plants, and will thrive in a deep rich loam anywhere, excepting under the shelter of trees. Cuttings struck, or seeds sown, during April or May generally make fine, dense, cushion-like growths, if transplanted on to a somewhat cool or shaded border, and carefully lifted in the autumn; the cuttings are best "drawn," or grown until they are soft, in a frame before they are removed. Where a stock of old plants exist, layer the long slender branches any time after flowering, and cover with a mixture of sand and leaf soil; they will then root freely and establish themselves in time for spring blooming, for which purpose, when grown en masse, they are most useful. After flowering, they may be divided and transplanted.

FIG. 193. AUBRIETIA DELTOIDEA.

> A. deltoidea (deltoid).* fl. purple; petals twice the length of the calyx; pedicels short, filiform; racemes opposite the leaves and terminal, lax, few-flowered. Early spring. l. with one or two large teeth on each side (therefore they are rhomboidal, not truly deltoid), scabrous, with short branchy stellate hairs. h. 2in. to 4in. Naples, &c., 1710. There are several garden varieties, the best of which are described below; most of them are regarded as distinct species. See Fig. 193. (S. F. G. 628.)

FIG. 194. AUBRIETIA PURPUREA.

> A. d. Bouganvillei (Bouganville's).* fl. light violet purple, with very even imbricated petals. Habit very dwarf and compact, with short peduncles. A pretty form.

> A. d. Campbelli (Campbell's).* Larger deep violet blue flowers, and of far more vigorous constitution than the typical form. Grandiflora comes very near this. SYN. A. Hendersonii.

> A. d. Eyrei (Eyre's).* A very fine variety, with a free branching habit, and large flowers of a rich violet-purple colour, rather longer than broad. A. olympica is very near, if not identical with this.

> A. d. græca (Grecian).* fl. light purple. h. 4in. Greece, 1872. One of the best and largest flowered forms; very vigorous grower, with neat compact habit. A variety of this, named superba, has rather deeper-coloured flowers, produced over a very extended period. (R. G. 697.)

> A. d. purpurea (purple).* Larger flowers and more erect habit than the type. l. broader, with two to five teeth. Stems more leafy. There is a variegated form, which is very pleasing and effective, useful for carpeting or edging small beds. See Fig. 194.

> A. d. violacea (violet).* This is a hybrid form, even finer than Campbelli, with large deep violet-purple flowers, fading to reddish-violet, and is more effective than any of the others.

> A. Hendersonii (Henderson's). A synonym of A. d. Campbelli.

AUCUBA (the Japanese name of the shrub). ORD. Cornaceæ. A genus of hardy evergreen shrubs, thriving better than any other in the smoky atmosphere of dense cities. They grow in ordinary well-drained garden soil, and require no special culture. If grown in pots, they should be planted firmly in rather sandy yellow loam, with plenty of drainage. They should not be allowed too large pots, or an unfruitful growth is likely to result. During the growing season, an abundance of water is needed, which must be lessened when the plants are fully developed. If cultivated in the greenhouse or conservatory, they should be plunged out of doors during summer. To insure a good supply of the very ornamental berries, which are produced on the female plant, careful fertilising is necessary. The time for applying the pollen is when the pistil exudes a slightly gummy substance, and otherwise shows signs of maturity. When it happens, as is sometimes the case, that the male blooms are open and the pollen mature before the female blooms are ready, the pollen should be collected on a dry camel-hair pencil, transferred to a piece of glass, and covered over by another piece, both of which must also be dry. It may be applied afterwards when wanted, as it retains its power for some weeks. Propagated by cuttings, inserted in any light sandy soil, with or without a covering, in spring or autumn; or readily increased from seeds, sown as soon as ripe.

> A. himalaica (Himalayan).* l. lanceolate, or lanceolate acuminate; branches of the panicle very pilose. Berries spherical, not oblong. Himalaya. (F. d. S. 12, 1271.)

> A. japonica (Japanese).* l. opposite, petiolate, broad, ovate-lanceolate, acuminated, toothed, leathery, glabrous, shining, pale green, beautifully spotted with yellow, having the midrib rather prominent, the rest of the leaf reticulately veined. h. 6ft. to 10ft. Japan, 1783. The numerous varieties, both of the male and female forms, among which will be found many of great beauty, all differ, more or less, in the variegation of their leaves. They are in very general cultivation, and nearly every nurseryman has an assortment. Among the best of them are the following: albo-variegata, aurea, bicolor, latimaculata, limbata, longifolia, macrophylla, ovata, pygmæa, and pygmæa sulphurea.

AUDOUINIA (in honour of V. Audouin, a profound entomologist). ORD. Bruniaceæ. An ornamental greenhouse evergreen shrub, thriving in a mixture of peat and sandy loam. Propagated by cuttings of half-ripened wood, inserted in sand, under a bell glass, in gentle heat.

> A. capitata (headed). fl. purple, crowded into oblong, spike-like, terminal heads. May. l. spirally inserted, a little keeled. Branches erect. h. 1ft. to 2ft. Cape of Good Hope, 1790.

AULACOSPERMUM. A synonym of Pleurospermum (which see).

AULAX (from aulax, a furrow; the under surface of the leaves of the original species being furrowed). ORD. Proteaceæ. Greenhouse evergreen shrubs, from the Cape of Good Hope, thriving best in a compost of fibrous loam, leaf soil, and sharp sand, with thorough drainage. Ripened cuttings, taken off at a joint, and inserted in pots of sandy soil, will root readily under a hand glass, in a cool house.

> A. pinifolia (Pine-leaved). fl. yellow, racemose. July. l. filiform, channelled. h. 2ft. 1780.

> A. umbellata (umbelled). fl. yellow. June. l. flat, spathulate*-linear. h. 2ft. 1774. (B. R. 12, 1015.)

[146]

AURANTIACEÆ. An order of trees or shrubs, including the Orange and Lemon trees. Flowers fragrant. Fruit fleshy, edible. Leaves alternate, articulated above the stem, filled with transparent oil cysts, giving them a dotted appearance. Well-known genera are Citrus and Limonia.

AURICULA (Primula Auricula). This favourite spring flower (see Fig. 195) was, at one time, almost universally cultivated, but has of late years fallen into much neglect; it is now, however, happily regaining enthusiastic admirers. Although its culture is not nearly so difficult as is generally understood, a few special items of treatment are nevertheless necessary to grow it successfully.

FIG. 195. A VARIETY OF PRIMULA AURICULA.

Frames for the reception of Auriculas should be prepared, with a good bottom drainage, and an inside staging, similar to the back stage of a lean-to greenhouse, arranged as near the glass as possible. If the frames are about 4ft. wide, they will be very convenient; 1ft. deep in the front, and about 3ft. at the back. This will allow for a good stage arrangement. Of course, it is not necessary to construct an expensive staging, as common boards can be laid upon pots of various heights, the same results being practically secured. These frames should face north from May to October, and south in winter, during which latter time it will be necessary to well cover the sides with straw or brake. When frosty, the lights must also be mated; but, unless there is absolute fear of frost, the glass should not be covered, as the more light the plants receive the better. On all suitable occasions, both during summer and winter, air must be freely admitted, and a good look-out kept during showery weather; hence it may be necessary to tilt the lights with blocks rather than remove them entirely. The latter plan should be adopted whenever practicable, especially during early spring, and after they are well established in their fresh pots in summer. This will greatly assist to ripen the crown, and produce hard, stout foliage, which will endure the winter much better than if grown with less air. Many cultivators prefer small span or lean-to houses to frames; and it must be admitted that these are better, more convenient, and in every way more beneficial. Simple, inexpensive structures, no higher than is absolutely necessary for convenience, with top and side ventilation, will meet all requirements; and if a 2in. hot-water pipe is arranged next the eaves inside, it will be a decided advantage during very severe weather.

Soil. The best compost that can be prepared for Auriculas is as follows: Four parts good fibrous loam, one part well-rotted cow manure, one part good leaf soil, and one part coarse river or silver sand, with a little charcoal or pounded oyster-shells added. Carefully mix the whole together before using. The loam should be stored about twelve months previous to being used, and it should be selected from districts with a fine atmosphere; the turf should be cut about 3in. thick. Cow manure that has lain for a year or so, and been subjected to sharp frosts, is most suitable, as insect life, which it very probably contains, is thereby destroyed, and the whole materially sweetened.

Potting. This operation requires to be carefully done as soon after flowering as possible, unless it is desired to save seed, when it must be deferred until the seed is ripened. May and June are the best months for general potting, and whatever the size of the pots used, they should be carefully and thoroughly drained. After a good layer of potsherds, place some charcoal, leaf mould, or spent hops. Many good growers use the last very advantageously. For good flowering plants, 48-sized pots are used, many cultivators preferring glazed pots to the unglazed; but such are not absolutely necessary to ensure success. Before repotting, remove most of the old soil, and with a sharp knife cut off any bruised or cankered portion of roots; the stout tap-root may also be cut away if devoid of fresh rootlets. Do not pot very firmly. Remove the plants to their summer quarters, withholding water for a few days, and keep the frames close. About a week after potting, water may be advantageously given, the plants will then soon resume root-action, and air may be admitted afterwards on all suitable occasions. The collar or neck of the plant must be left well above the surface of the soil.

Watering is a point that requires careful attention, as neglect in this matter will result in failure. During the growing season, Auriculas require an abundance of water; in fact, they must never be allowed to get dry. In the winter, they must only be watered when they are really dry, especially during a severe season. Care must be taken to avoid watering the leaves, particularly in early spring, as this tends to spoil the effect of the charming farinose foliage. Above all, water must not be allowed to stand in the heart of the plant, as such will inevitably cause incipient decay. Hence it is necessary to keep a sharp lookout for drippings from the glass, and to maintain tightly-glazed frames. On all occasions, decaying leaves must be removed, and especially during winter.

Top-dressing. About the middle or end of February, when the plants commence new growth, the surface soil should be removed about an inch or so deep, and the pots re-filled with a rich compost made up of the following: Two parts of turfy loam, one of rotten cow or hen manure, and one of leaf soil; if a little Standen's Manure is added, the compost will be improved. After this top-dressing, the plants may be watered freely.

Propagation by Offsets. When top-dressing, any offsets with roots should be removed, and as soon after as possible the remaining ones should be taken off, as it is much more desirable to do so early than later on, when repotting; for, when making the first growth, they are the more likely to root better, and stand a greater chance of making good plants before the season is over. Fill well-drained 3in. pots with sandy soil, and arrange about four offsets round the sides; place under a bell glass, or in a close handlight, watering very sparingly so as to prevent them damping off. They will soon establish themselves, after which air may be admitted, and the plants may ultimately be potted off singly. To induce choice varieties to make offsets, the top of the old plant should be removed and treated like the others, when, as a rule, several shoots will be produced, which in due time may be removed. By this means, a nice stock of the rarer kinds may be obtained; whereas, if such a course were not adopted, the rate of increase would be extremely slow.

Flowering. During the flowering period, watering, as already stated, must be carefully attended to, for if the plants are allowed to get dry, the flowers will quickly shrivel. They must also be kept well shaded from sunshine, which quickly destroys the delicate blossoms. As the trusses are developing, particular attention must be given[147] to night protection. It is, perhaps, better to cover every night than to run the risk of exposing the unexpanded flowers to frost, as the effect is very prejudicial; in fact, if subject to frost, smooth even flowers may not be expected.

Seed Saving and Sowing. The only way to obtain new varieties is by seed; hence the value of careful seed-saving will be apparent. Severe discrimination must be exercised in the selection of parents, and the flowers must be very carefully crossed. The anthers should be removed from the pistillate parent, if possible, before expansion, so as to prevent any possibility of self-fertilisation; and, when the stigma is ready, the pollen must be conveyed by means of a small camel's-hair brush, care being taken not to mistake the brushes used in different classes. It has been observed in Auriculas that the issue from crossbred seed favours the pollen more than the pistillate parent; hence the necessity of selecting good pollen parents. It is best to confine hybridisation to separate classes—i.e., cross a Self with a Self, and a Green-edged variety with another of the same class. The importance of selecting the best in each class scarcely needs suggestion, having regard to constitution as well as the quality of the flowers. The seed should be sown as soon as ripe, or early in March, in well-drained pots, filled with sandy soil, which must be well watered previous to sowing. When this operation is completed, the seed must be lightly covered with coarse sand, a sheet of glass placed over the pot, and the latter stood in the hand glass, where the offsets are rooted. Some of the seedlings will appear in a month, but the bulk from that sown when ripe will not be seen until the following spring; while others will germinate even during the ensuing summer. The late comers should be particularly cared for, as they frequently produce the best varieties. When the seedlings are large enough, they must be pricked off in pots of sandy soil; and, when well established, potted off singly into small thumb pots, and afterwards encouraged as judgment suggests. Some growers allow the seedlings to remain in the store pots till they flower, when the best are kept, and those not required disposed of.

Insect Pests. Green fly are often very troublesome, and should be exterminated as speedily as possible, by tobacco fumigation, or by dipping the plants in a solution of Gishurst's Compound, or carefully prepared Fir-tree Oil, all of which are effectual. Many authorities denounce fumigation, while others advocate it. The roots are also attacked by a mealy louse, named Trama auriculæ, which clusters about the roots and collar of the plants, sucking nutriment therefrom; and although, provided they do not attack the collar, they have no greatly prejudicial effect on the plant, yet it is desirable to exterminate them. The only effectual way of accomplishing this is to remove all soil, and thoroughly cleanse the roots and collar in a solution of soft soap, with a little Fir-tree Oil added. Of course, this is most easily managed when repotting; and, unless the plants are very badly infested, it would not be advisable to run the risk of root washing later in the year.

Classes. Auriculas are now arranged in five classes, four of which constitute what are known as "show or stage Auriculas," while the other is known by the name of "Alpines." Each class is characterised by special points of distinction, which, in the opinion of the strict "florists" school, it is of the utmost importance to observe; and as there is room for systematists in this, as well as in any other branch of floriculture, we will follow the arrangement usually adopted, and describe the distinguishing features of, and enumerate some of the best varieties in, each class, with their raisers' names attached:

> Green-edged. Outer edge green, or but sparingly dusted with powder; next, a zone of colour known as the body colour, which varies, the darkest being most esteemed; both edges of this zone should be even, especially the inner one, but there are few flowers perfect in this respect. Next to the body-colour is the paste, which occupies the space between the inner circle of the latter and the throat, this should be pure and dense, with a distinctly circular outline at the throat; the throat and tube should be bright yellow. Of course, this ideal standard has not yet been reached, as there are supposed defects in all or some sections of the flowers at present known. Leading Varieties: ADMIRAL NAPIER (Campbell), ALDERMAN WISBEY (Headley), APOLLO (Beeston), CHAMPION (Page), COLONEL TAYLOR (Leigh), DUKE OF WELLINGTON (Dickson), FREEDOM (Booth), GENERAL NEILL (Traill), HIGHLAND BOY (Pollitt), IMPERATOR (Litton), LADY ANN WILBRAHAM (Oliver), LORD PALMERSTON (Campbell), LOVELY ANN (Oliver), LYCURGUS (Smith), PRINCE OF GREENS (Traill), PRINCE OF WALES (Ashton).

> Grey-edged. Edge heavily dusted with powder, so as almost to hide the normal green colour; other points same as the Green-edged varieties. Leading varieties: ALEXANDER MEIKLEJOHN (Kay), CHAS. E. BROWN (Headley), COMPLETE (Sykes), CONQUEROR OF EUROPE (Waterhouse), DR. HORNER (Read), F. D. HORNER (Simonite), GENERAL BOLIVAR (Smith), GEORGE LEVICK (Walker), GEORGE LIGHTBODY (Headley), JOHN WATERSTON (Cunningham), LANCASHIRE HERO (Lancashire), RICHARD HEADLEY (Lightbody), ROBERT TRAILL (Lightbody).

> White-edged. Edge so heavily dusted with farina as to completely hide the green and give it a white appearance; the powder frequently as dense as on the paste portion; other points like the first. Leading varieties: ACME (Read), ANNE SMITH (Smith), ARABELLA (Headley), BEAUTY (Traill), BRIGHT VENUS (Lee), CATHERINA (Summerscales), CONSERVATIVE (Douglas), COUNTESS OF WILTON (Cheetham), EARL GROSVENOR (Lee), FAVORITE (Taylor), FRANK SIMONITE (Simonite), GLORY (Taylor), JOHN SIMONITE (Walker), NE PLUS ULTRA (Smith), REGULAR (Ashworth), SMILING BEAUTY (Heap), SYLVIA (Douglas), TRUE BRITON (Hepworth).

> Selfs. Tube bright yellow, and circular at the top; paste dense, pure, with an even edge; all the rest of the flower of one colour, without shades or edging; any colour holds good. Leading varieties: APOLLO (Hay), BLACKBIRD (Spalding), C. J. PERRY (Turner), DUKE OF ARGYLE (Campbell), FORMOSA (Smith), GARIBALDI (Pohlman), HELEN LANCASTER (Pohlman), LORD OF LORNE (Campbell), MAZINNA (Pohlman), METEOR FLAG (Lightbody), METROPOLITAN (Spalding), MRS. DOUGLAS (Simonite), MRS. STURROCK (Martin), OTHELLO (Netherwood), PIZARRO (Campbell), TOPSY (Kaye).

> Alpines. Centre golden yellow, or white, and destitute of powder; body colour various; edge one-coloured, shading off paler towards the margin. These are much hardier than any of the other classes, and will do well outside in most places. Leading varieties: A. F. BARRON (Turner), BEATRICE (Turner), BLACK PRINCE (Turner), BRONZE QUEEN (Turner), COLONEL SCOTT (Turner), DIADEM (Gorton), DUCHESS OF CONNAUGHT (Turner), EVENING STAR (Turner), GEORGE LIGHTBODY (Turner), JOHN LEECH (Turner), MRS.

THOMSON (Turner), QUEEN VICTORIA (Turner), RUBENS (Turner), SAILOR PRINCE (Turner), SELINA (Turner), SPANGLE (Turner), SYDNEY (Turner), TRIUMPHANT (Turner).

AURICULATE. Having ear-like appendages.

AUSTRIAN ROSE. See Rosa lutea.

AVENA (derivation obscure). The Oat. ORD. Gramineæ. A genus of grasses with loose panicles and compressed spikelets. Of agricultural importance only, with the following exception, which is an annual of easy culture in ordinary garden soil. Propagated by seeds, sown in spring or autumn.

> A. sterilis (barren). The Animated Oat. fl. in drooping panicles of large spikelets. h. 1½ft. to 2ft. Barbary, 1640. An elegant plant.

AVENS. See Geum.

AVENUES. In forming an Avenue, the plan must neither be tortuous nor of a "tedious sameness," but a gradually winding line should, above all, be obtained, which must in no way interfere with the view from the house. About 12ft. is the width usually allowed for the road, but this depends upon individual taste or idea—this remark applies to planting in double rows, the trees forming a series of triangles, or in single rows. The distance across the road from one row of trees to those opposite should be at least 24ft. The Lime is extensively used for Avenues on account of its regular growth and the shade it affords. The Cedar of Lebanon is one of the best and most suitable evergreens. The Dutch Elm is used because of its rapid growth, and forms one of the best deciduous trees for this purpose. The well-known Horse Chestnut, in sheltered spots, is very ornamental, as is also the Spanish Chestnut; the latter spreads rapidly. Where immediate effect is required, nothing gives more satisfaction than the White Poplar; it grows in a wet soil better than anything else.[148] Deodars, Araucarias, Douglas Pine, the Mexican, Chinese, and Japanese Cypresses, and many others, are eminently suited for Avenue planting. Shrubs and herbaceous plants should be introduced between the trees, and so remove any bareness that may occur. Diervilla rosea, and its variegated form, Aucubas, Rhododendrons, Hypericums, and many others, could be mentioned to serve this purpose. A moderately good soil will be found to answer generally.

AVERRHOA (in honour of Averrhoes, of Cordova, a celebrated Arabian physician, who resided in Spain during the domination of the Moors, about the middle of the twelfth century; he translated Aristotle into Arabic). ORD. Geraniaceæ. Ornamental stove trees, thriving in loam and peat. Half-ripened cuttings will strike in sand, under a hand glass, about April, with bottom heat. The leaves of the first-named species are irritable to the touch.

FIG. 196 AZALEA BALSAMINÆFLORA.

> A. Bilimbi (Bilimbi-tree). fl. reddish purple, disposed in racemes, rising from the trunk.

AXILLARY. Growing in the axil of anything.

AYRSHIRE ROSE. See Rosa repens capreolata.

AZALEA (from azaleos, dry, arid; in allusion to the habitat of the plant). ORD. Ericaceæ. A genus of very popular and beautiful hardy or greenhouse plants. The species enumerated were included under Rhododendron by Don, Loudon, and others, contrary to the classification of Linnæus, but the distinctive characters are not consistent. In this genus, the stamens are usually five, but in Rhododendron ten is the typical number.

Ghent or American Azaleas. These are extremely[149] popular hardy deciduous shrubs. When plants are grown in the open, artificial crossing will be unnecessary; but this method must be employed upon those grown in the cool greenhouse, if well fertilised seeds are required. The seed should be gathered and sown when ripe in a large shallow frame containing from 2in. to 3in. of peat, over which more peat must be laid very level by means of a fine sieve; or they may be kept until early the following spring. No covering will be necessary, but a thorough watering with a fine-rosed water-pot must be given. The lights should be darkened, and the frames kept close until the young seedlings begin to appear, when they must have air (carefully admitted), shade, and a daily sprinkling of water. By the autumn, they will be large enough to transplant in small clumps into boxes of peat and coarse sand, and to place in other frames, or in the open. In each case, they will need watering, shading, and to be kept close until growth commences. The hardier the plants are before winter commences, the better; but a protection of mats or similar material will prevent the probability of their being killed by severe frosts. During the following season, they will only require water during dry weather, and no protection need be afforded this winter. The next spring, they should be planted out singly in beds, sufficiently wide apart to allow the development of two years growth. If an upright growth is being made, the leading shoot must be shortened, in order to secure dwarf, well-branched plants. The same methods should be employed on a smaller scale where but a few are wanted. Grafting is largely practised to increase the stock of named varieties or choice seedlings, the stock employed being A. pontica. This process, of course, ensures the quicker production of flowering plants. Layering in March, encasing the part buried with moss, is also some times practised; but the layer must be left two years before separating. Cuttings of the last year's wood, 2in. or 3in. long, taken with a heel, root readily in sand; about the end of August is the best time for so doing. If they are pricked off in pots or pans of sandy soil, and kept in a cool frame until they are calloused, and afterwards introduced into a slight bottom heat, they root quicker, but this is not absolutely essential. When placed outside, they should be covered with a handlight for about two months, and, at the end of this time, air should be gradually given and increased. Ghent Azaleas are now forced extensively for the market as well as in private gardens; and, by judicious culture, they can be had in full blossom by Christmas. With this end in view, they should be grown in pots, and have the growth prematurely completed soon after flowering with the aid of a little artificial heat; after which they may be placed outside. During very hot and dry weather, the north side of a wall is necessary, to prevent their flowering in the autumn. The same plants must only be forced every alternate year. Commence to place the plants in heat in October, and keep up a succession until the following March. The best plants for forcing purposes are obtained from the Continent, where they are grown in enormous quantities. When grown permanently out of doors, the most suitable soil is peat and rough sand mixed. Failing this, leaf mould, maiden loam, and sand, will be found satisfactory. In many cases, we have known them to flourish in ordinary garden soil.

> The following varieties of Ghent Azaleas are distinct, and all worth growing; ADMIRAL DE RUYTER, deep red-scarlet, very fine; ALTACLERENSIS, bright yellow; AMŒNA, light pink; CARNEA ELEGANS, pale pink, shaded sulphur; COCCINEA MAJOR, dark scarlet, very fine; CUPREA SPLENDENS, rich pink, shaded yellow; DECORATA, lovely pink; DIRECTEUR CHARLES BAUMANN, rich vermilion, spotted yellow; ELECTOR, rich orange-scarlet; GEANT DES BATAILLES, deep crimson, very fine; MADAME JOSEPH BAUMANN, bright pink, very free and good; MARIA VERSCHAFFELT, shaded pink and yellow; MIRABILIS, very lovely pink; MORTERI, rich yellow, shaded rosy-red; PONTICA MACRANTHA, rich deep sulphur, very large and fine; PRINCESSE D'ORANGE, salmon-pink, very fine; SANGUINEA, deep crimson; VISCOSA FLORIBUNDA, pure white, very fragrant.

> A. arborescens (tree-like).* fl. large, reddish, not clammy, leafy; tube of corolla longer than the segments; calyx leafy, with the segments oblong and acute. May. l., of the flower buds large, yellowish-brown, surrounded with a fringed white border, obovate, rather obtuse, smooth on both surfaces, glaucous beneath, ciliated on the margins, and having the midrib almost smooth. h. 10ft. to 20ft. Pennsylvania, 1818. Deciduous species.

> A. balsaminæflora (Balsam-flowered).* fl. bright salmony red, finely double and rosette-like, the segments regularly imbricated, much resembling in general appearance the blooms of a Camellia-flowered Balsam. Japan. It is a distinct species, and remains in bloom for a considerable period; the flowers are invaluable for bouquets. See Fig. 196, for which we are indebted to Mr. Bull.

> A. calendulacea (Marigold-like).* fl. yellow, red, orange, and copper coloured, large, not clammy, rather naked; tube of corolla hairy, shorter than the segments. May. l. oblong, pubescent on both surfaces, at length hairy. h. 2ft. to 6ft. Pennsylvania to Carolina, 1806. This is said to be the handsomest shrub in North America. There are several varieties of it in cultivation. Hardy; deciduous. (B. M. 1721, 2143.)

> A. hispida (bristly). fl. white, with a red border and a tinge of red on the tube, which is wide and scarcely longer than the segments, very clammy, leafy; stamens ten. July. l. long-lanceolate, hispid above, and smooth beneath, glaucous on both surfaces, ciliated on the margins, and having the nerve bristly beneath. Branches straight, and very hispid. h. 10ft. to 15ft. New York, &c., 1734. A hardy deciduous species. (W. D. B. 1, 6.)

FIG. 197. FLOWER OF AZALEA LEDIFOLIA.

> A. ledifolia (Ledum-leaved).* fl. pure white, showy; corolla campanulate; in threes at the extremities of the branches; calyx erect, glandular, and viscid. March. l. elliptic-lanceolate. h. 2ft. to 6ft. China, 1819. The whole shrub is very hairy. Hardy; evergreen. SYN. A. liliiflora. See Fig. 197. (B. M. 2901.)

> A. liliiflora (lily-flowered). Synonymous with A. ledifolia.

> A. nudiflora (naked-flowered).* fl. in terminal clustered racemes, appearing before the leaves, rather naked, not clammy; tube of corolla longer than the segments; teeth of calyx short, rather rounded; stamens much exserted. June. l. lanceolate-oblong, nearly smooth and green on both surfaces, ciliated on the margins, having the midrib bristly beneath, and woolly above. h. 3ft. to 4ft. North America, 1734. This species hybridises very freely with A. calendulacea, A. pontica, A. viscosa, &c., and descriptive lists of a host of hybrids of almost every conceivable shade, both double and single, are to be found in continental and home catalogues, to which the reader is referred. Hardy. (W. F. A., t. 36.)

> A. pontica (Pontic).* fl. leafy, clammy; corolla funnel-shaped; stamens very long. May. l. shining, ovate, oblong, pilose, ciliated. h. 4ft. to 6ft. Levant, Caucasus, &c., 1793. The varieties of this species are also numerous, differing principally in the colour of the flowers and the hue of the leaves. The flowers are of all shades, and frequently striped. The name generally adopted, as above, must not be confounded with Rhododendron ponticum. If the genus Azalea is merged into Rhododendron, as is done by most systematists, this plant must be called by Don's name, Rhododendron flavum. (I. H. 1864, 415.)

> A. procumbens (procumbent). See Loiseleria procumbens.

> A. speciosa (showy).* fl. scarlet and orange coloured; corolla silky, with obtuse, ciliated, lanceolate, undulated segments; calyx pubescent. May. l. lanceolate, ciliated, acute at both[150] ends. Branches hairy. h. 3ft. to 4ft. North America. The varieties of above are several, varying in the shape of the leaves and the colour of the flowers. (L. B. C. 1255)

> A. viscosa (clammy).* fl. white, sweet-scented, in terminal clusters, downy, clammy, leafy; tube of corolla as long as the segments. July. l. oblong-ovate, acute, smooth, and green on both surfaces, ciliated on the margins, having the midrib bristly. h. 2ft. to 4ft. North America, 1734. Like nearly all species belonging to this genus, the varieties are many, varying in the colour of the flowers and otherwise. (T. S. M. 438.)

> A. v. nitida (shining).* fl. white, tinged with red, clammy, leafy; tube of corolla a little longer than the segments. April. l. oblanceolate, rather mucronate, leathery, smooth on both surfaces, shining above, having the nerve bristly beneath, with revolute, ciliated margins. h. 2ft. to 4ft. New York, 1812. Hardy; deciduous. (B. R. 5, 414.)

Indian or Chinese Azaleas. This is a section of greenhouse evergreen varieties obtained from A. indica (which see), blooming continuously from November to June, or even later, and of the greatest value for all purposes, whether for decoration, cutting, or exhibition. Cultivation: Thorough drainage is essential, and a compost of half peat, the other half made up of fibrous loam, leaf soil, and sand, in equal quantities. They cannot have too much light and air, and may be grown to almost any size by shifting from one pot to a size larger. In repotting, the whole of the crocks should be taken away from the base of the ball of soil and roots, and the top should also be removed till the fine roots are reached. The plant should then be put in the new pot, and the additional soil rammed firm, in order to prevent the water running through it, and thus depriving the plant of any benefit therefrom. In all cases, the roots near the stem must be above the soil, so that the water may not sink in next the stem, or death will most certainly ensue. After potting, for a few days the plants should be kept close and freely syringed, and as the growth is completed, they may be well hardened off. The best time for potting is after flowering, before the new growth has been made. From October to June the plants should be in the greenhouse, and during the other months in a cold frame, or plunged in pots in the open; or, what is preferable in favoured localities, planted out in prepared beds; they will thus be kept cleaner, and the growth will be much superior. In autumn they may be lifted and repotted, placing in a shady position for a few days. Water in abundance must be given throughout the blooming and growing season; and the plants must, on no account, be allowed to become dry. At the same time, a proper amount of care is most essential, as an excessive amount of moisture is equally as fatal as drought. Cuttings should be placed in sand under a bell glass with moderate bottom heat; half-ripened ones are preferable. They must be cut up to a joint—the base of a leaf—the lower leaves for an inch stripped off, and the stem stuck into the sand, which should lay, about an inch thick, on the top of sandy peat soil; the bottom of the cuttings should reach, but not go quite into, the soil. The whole should be covered with a bell glass, which must be wiped dry every morning. Soon after the cuttings have commenced growing, place them in small pots. They are also very largely and easily increased by grafting; indeed, this is the only satisfactory method of securing standards. Seeds may be sown similar to the last section, but in the greenhouse, and, when well up, pricked out into little pots 1in. apart. Azaleas are liable to the attacks of thrips and red spider, the latter being especially troublesome if the plants are in a dry position; frequent syringing will materially help to eradicate both pests. If insufficient, syringe with a solution of Gishurst's Compound.

> A. amœna (pleasing). fl. almost campanulate, rich crimson, about 1½in. across, hose-in-hose conformation, produced in great profusion. April. l. small, size of the common Box, hairy. h. 1ft. China. This is an elegant little neat and compact growing shrub, which has proved to be quite hardy in England. (B. M. 4728.) A very beautiful series of hybrids have been obtained by crossing this species with A. indica, which are most serviceable and free. The following are most desirable: LADY MUSGRAVE, light carmine; MISS BUIST, pure white; MRS. CARMICHAEL, rich magenta, shaded crimson; PRIME MINISTER, soft pink, deep shaded, very free; PRINCESS BEATRICE, light mauve, very distinct and free; PRINCESS MAUDE, rich magenta, rose shaded.

FIG. 198. FLOWER OF AZALEA INDICA.

> A. indica (Indian).* fl. campanulate, terminal, solitary or twin; calycine teeth long-lanceolate, obtuse, ciliated, spreading. l. cuneate-lanceolate, finely crenelated, covered with sharp, close-pressed rigid hairs, attenuated at both ends. Branches also covered with sharp, close-pressed, rigid hairs. h. 3ft. to 6ft. China, 1808. See Fig. 198. There are a great number of garden seedlings of the Indian Azalea, including every shade and colour. A selection to any extent may be made from the nurserymen's catalogues, but, for the guidance of the amateur, we have made a rigid selection of the best double and single varieties.

> Double-Flowered: A. BORSIG, pure white; ALICE, rich deep rose, blotched with vermilion, very fine; BERNARD ANDRé, dark violet-purple, large, semi-double; CHARLES LEIRENS, dark salmon, good form and substance; COMTESSE EUGENIE DE KERCHOVE, white, flaked with red-carmine, semi-double; DOMINIQUE VERVAENE, bright orange, very fine; DR.

May. l. slowly deciduous, elliptic, acutish, pilosely pubescent, feather-nerved, with ciliated margins, greyish beneath. h. 3ft. to 4ft. China and Japan. A large number of seedlings and hybrids from this species are in cultivation, known under the name of Japanese Azaleas, and all are valuable for the decoration of the cool conservatory, or for outdoor work. SYN. A. mollis. (L. B. C. 885.)

AZARA (in honour of J. N. Azara, a Spanish promoter of science, but of botany in particular). ORD. Bixineæ. Showy evergreen, hardy and half-hardy shrubs, with alternate, simple, stalked stipulate leaves, and fragrant flowers.[151] They thrive well in a compost of loam, leaf soil, and sand. Ripened cuttings root readily if placed in sand, under glass, in slight heat. It is believed that all the species enumerated will prove hardy if a slight winter protection in midland and northern counties be afforded. This precaution will be unnecessary in more southern parts.

> A. dentata (toothed). fl. yellow; corymbs sessile, few-flowered. June. l. ovate, serrated, scabrous, tomentose beneath; stipules leafy, unequal in size. h. 12ft. Chili, 1830. (B. R. 1728.)

> A. Gillesii (Gilles').* fl. bright yellow; panicles axillary, densely packed. Spring. l. large, Holly-like, ovate, coarsely toothed, smooth. h. 15ft. Chili, 1859. (B. M. 5178.)

FIG. 199. AZARA MICROPHYLLA, showing Habit, and Foliage (half natural size).

> A. integrifolia (entire-leaved).* fl. yellow, on numerous short axillary spikes, of an aromatic fragrance. Autumn. l. obovate or oblong, entire, smooth; stipules equal, permanent. h. 18ft. Chili (about Conception), 1832. The variegated-leaved form, although rare, is very ornamental. The variegation consists of greenish-yellow, with a blotch of dark green, and in a young state edged with deep pink.

> A. microphylla (small-leaved).* fl. greenish, corymbose, succeeded by numerous small orange-coloured berries. Autumn. l. small, distichous, obovate, obtuse, dark-shining green. h. 12ft. Chiloe and Valdavia, 1873. This shrub is very ornamental as a standard, and also excellent for covering walls. Quite hardy. See Fig. 199, for which we are indebted to Messrs. Veitch and Sons.

BABIANA (from babianer, the Dutch for baboon; in reference to the bulbs being eaten by baboons). ORD. Iridaceæ. A genus of very ornamental bulbous plants confined to the Cape of Good Hope, with the exception of a single species, which is found in Socotra. Flowers occasionally fragrant, and generally characterised by their rich self-colours, or the striking contrast of very distinct hues in the same flower; perianth regular and symmetrical, with six ovate divisions (tube varying in length). Stems from 6in. to 9in. high, arising from a small bulb-like corm, and bearing tapering plaited leaves, which are usually more or less densely covered with long hairs; the scapes are racemose, each bearing about six or more simultaneously expanding flowers. They may be successfully grown in pots. By this plan there is, perhaps, less danger of loss, and their flowering season can be prolonged considerably. A light sandy compost, with a small proportion of well-decayed manure, is required, and thorough drainage is also most essential. Use 48 or 60-sized pots, placing four or five corms in the former, and two or three in the latter, and keep moderately dry until they commence to form roots. October is the best time to pot. As soon as the plants appear above ground, water may be carefully given, and the supply pro[152]portionately increased as the plants develop. Very weak liquid manure, applied twice a week, just as the spikes are pushing up, will be beneficial. When the flowers fade, and the stems show signs of decay, the supply of water must be gradually decreased, thus inducing the thorough maturation of the corms, upon which the next season's display depends. When quite down, store the pots in a dry place till the time for repotting arrives, when the corms should be carefully cleaned, and all offsets separated, the latter being potted up in the same way as the parent corms in order to produce flowering specimens; or they may be kept in a pot of sand and planted in a warm border outside in March. Outdoor culture: A sheltered, sunny, and well-drained situation is most essential to success. Although not absolutely necessary, it is preferable to replant every year in early spring, placing the bulbs about 5in. or 6in. deep, with a little sand sprinkled about them. Planting may, of course, be done in autumn, when it will be necessary to cover with cocoa nut fibre refuse to the depth of 5in. or 6in. In warm, sheltered situations, the corms may remain undisturbed; but, as a rule, it is desirable to remove them late in autumn, when the leaves are dead, and store them in dry sand through the winter in a cool, airy position, free of frost. Mixed Babianas may be purchased from dealers at a cheap rate, and, for general purposes, they are best to plant. Propagation may be effected by offsets and seeds. The former is the best and quickest method. The offsets should be grown in boxes or planted out in light rich soil until large enough for flowering. Seeds sown in pans, and placed in a gentle heat, will grow at almost any time; the young plants will require to be carefully transplanted each season until they develop into blooming corms.

BABINGTONIA (named after C. C. Babington, Professor of Botany at Cambridge, and a distinguished botanical author). ORD. Myrtaceæ. A very pretty greenhouse evergreen shrub, allied to Bæckea, from which it differs in having the stamens collected in groups opposite the sepals. Cuttings of the young unflowering shoots may be planted in sand under a bell glass, and kept in a moderate heat until rooted, when they should be placed singly in small pots, in a compost of equal parts loam and peat, with the addition of a little sand. As the small pots fill with roots, the plants should be removed into larger ones, and the compost have less sand in it; but this should not be done until the next February. The established plants must have a good shift about March or April, and should be kept in a light, airy greenhouse; the first shoots may be topped to moderate their vigour, and to produce a greater profusion of less luxuriant ones. In May, when most plants are removed from the greenhouse, these should be set to grow under a frame which, while shielding them from heavy rains, and supporting some slight shading in the hottest parts of the sunny days, will not prevent a free circulation of air. To this end, the frame should be elevated from the rests or supports at its corners; the lights should be left off at night in fine, mild weather, and on dull, cloudy days, being only replaced during heavy rains, and when shading is necessary. Towards autumn, the plants must be returned to the greenhouse.

> B. Camphorasmæ (camphor-smelling).* fl. pinkish-white, in little cymes, disposed in long terminal racemes. Summer. l. linear, opposite, nerved. h. 7ft. Australia, 1841. (B. R. 28, 10.)

BACCATE. Berried, fleshy; having a pulpy texture.

BACCHARIS (from Bacchus, wine; referring to the spicy odour of the roots). Ploughman's Spikenard. ORD. Compositæ. A genus of hardy, stove, or greenhouse herbs, shrubs, or trees. Flower-heads many-flowered, diœcious, terminal. Involucre sub-hemispherical or oblong, in many series, imbricated. Leaves simple, alternate, exstipulate, deciduous, oblong-lanceolate, notched, serrated, or entire. Shrubs of short duration. These plants are neither beautiful nor ornamental, but are of easy cultivation in ordinary soil. Propagated by cuttings.

> B. halimifolia (Halimus-leaved). Groundsel Tree. fl.-heads white. July. l. oblong-cuneate, obovate, coarsely toothed; branches angular. h. 6ft. to 12ft. Northern United States, 1683. Hardy.

BACONIA. A synonym of Pavetta (which see).

BACTRIS (from baktron, a cane; the young stems being used for walking sticks). ORD. Palmaceæ. Very ornamental, slender growing, and prickly stove palms. Peduncle of the spadix bursting through about the middle of the leaf sheath. Drupes small, ovate, or nearly round, and generally of a dark blue colour. Leaves pinnatisect; segments generally linear and entire. Instead of being confined to the apex of the trunk, the leaves are scattered over nearly the whole surface, and the lower ones retain their verdure long after the upper ones have fully developed. Stems slender, varying from 2ft. to 10ft. in height. Some of the species are of easy culture in a compost of loam, peat, loaf mould, and sand, in equal parts; but most of them are very difficult to manage. Propagation may be effected by suckers, which are very freely produced. Many species are ornamental only when in a young state.

Probably the only one in cultivation is that mentioned below; it is a very pretty plant, of easy culture in ordinary garden soil. Propagated by seeds, sown in spring.

> B. chrysostoma (golden-mouthed). fl.-heads bright yellow, solitary, terminal, about 1in. across; involucre of about ten leaflets, in two series. Early summer. l. linear, opposite, entire. Stems erect, downy. h. 1ft. California, 1835. (S. B. F. G. ii. 395.)

BAGGED. Swelled like a sac or bag.

BAHIA (probably from Port of Bahia, or San Salvador, in South America). SYN. Phialis. ORD. Compositæ. An ornamental, hardy, herbaceous perennial, much branched from the base of the stem, and having a greyish appearance. It may be increased by seeds, or by divisions.

> B. lanata (woolly). fl.-heads yellow, solitary, produced in great numbers. Summer. l. alternate, or with the lower ones sometimes opposite, deeply divided, and sometimes ligulate and entire. h. 6in. to 15in. North America.

BALANTIUM (of Desvaux). See Parinarium.

BALBISIA (commemorative of Giovanni Battista Balbis, a Professor of Botany at Turin). SYN. Ledocarpum. ORD. Geraniaceæ. A very ornamental half-hardy evergreen shrub, requiring a cool, dry atmosphere. As it is very liable to rot off, water must be applied with great care. Propagated by cuttings of half-ripened wood, inserted in sand, under a hand glass; or by seeds.

> B. verticillata (whorled). fl. yellow, large, with a whorl of narrow bracts beneath. Autumn. l. opposite, three-parted; segments linear-oblong. Branches slender, glaucous. h. 3ft. to 6ft. Chili, 1846. (B. M. 6170.)

BALCONY. A projection from the external wall of a house, usually resting on brackets, and having the sides encompassed by a balustrade. It should at all times be prettily decorated with plants, which in the summer is a comparatively easy matter. During winter, evergreens of various kinds are most serviceable, the best being Arbutus, Aucubas, Boxes, Euonymuses, Hollies, Irish and Goldon Yew, Portugal Laurel, Retinosporas, Vincas, &c. These may be grown in pots, and when replaced by the summer occupants, should be plunged in some reserve quarter, where they should receive plenty of water; by this means, they will increase in size, and keep in a healthy condition. Very little water will be required during the winter. Climbing plants, such as Ivy, Passion Flower, Virginian Creeper, Climbing Roses, &c., are indispensable for covering the trellises, and draping the pillars and arches.

BALDINGERA. A synonym of Premna.

BALL. This term is used in reference to the roots and mass of earth as they are moulded into form and pressed into hardness by the pot. The masses of roots and earth which, in the case of fibrous-rooted subjects (such as Rhododendrons), must be taken intact when removing the plants, are also termed Balls.

BALM (Melissa officinalis). A perennial herb, often used in the manufacture of a drink for sick persons, and sometimes employed for culinary purposes. It may be grown in ordinary garden soil, and is propagated by[154] divisions, in spring. A pretty variegated form is sometimes met with, having the additional advantage of being equal to the normal species for medicinal purposes.

BALM OF GILIAD. See Cedronella triphylla and Populus balsamifera.

FIG. 201. CAMELLIA-FLOWERED BALSAM.

BALSAM (Impatiens Balsamina). A well-known ornamental and tender annual, native of India. It is one of the showiest of summer and autumn flowers, and well deserves a place in every garden. Although of comparatively easy cultivation, good blooms and well-grown plants are far too rarely seen. A good Balsam bloom should be quite as double as a perfect Camellia, and to show to the greatest advantage should appear like one in the arrangement of the petals. To secure this, seeds should only be saved from the finest and most perfect flowers, although the quantity must, of necessity, be small. They should be sown, about the third week in March, in properly prepared pans of rich sandy soil, and placed in a gentle bottom heat of about 65deg. As soon as the first rough leaf appears, the plants should be potted off into 3in. pots, care being taken to let the cotyledon, or seed leaves, be close to the soil. When the roots touch the sides of the pots, the plants should be moved into larger ones, and this should be repeated until they are in 8in. or 10in. pots. Some growers place one or two seeds in small pots, so as to avoid the first shift, and a good plan it is. During the time the plants are under glass, they should be kept as near the light as possible, and be frequently turned around, so that they do not draw to one side; and careful training must be given to those that are required in fine form. Disbudding is also necessary to such as are wanted at their best, removing all bloom from the main stem and base of branches until the plants are of sufficient size, and then the buds at the tops will bloom almost simultaneously. The buds that will be formed afterwards will cause a continuance of blossom for a long time, in fact, for some months, if the plants are liberally supplied with liquid manure. If it is desired for them to flower out of doors, the plants should be transferred, about May, to a frame where the heat is not above 50deg., and be kept in a steady growing state, air being admitted on all suitable occasions, cold winds and heavy rains avoided, and water supplied when needed; never allow them to get dry. They require training and disbudding the same as those grown in the greenhouse. About June, the plants should be fully exposed during the day; and, when danger of frost is over, the lights may be kept off altogether. These should bloom at the end of July. In all cases, plenty of drainage must be allowed, as the amount of water required is very great. Insects must be sharply looked after, as well as slugs and snails. There are several sections, such as Camellia-flowered (see Fig. 201), Rose-flowered, &c., each containing variously striped, spotted, and entire coloured blooms, and it is best to pay an extra figure to secure a good strain.

BALSAM APPLE. See Momordica Balsaminea.

BALSAMINA. See Impatiens.

FIG. 202. BAMBUSA ARUNDINACEA.

BALSAMINEÆ. A tribe of plants belonging to the order Geraniaceæ. Sepals and petals all coloured, consisting of six segments, "two outer ones small, flat, and oblique; the next large, hood-shaped, ending below in a conical spur; the fourth opposite to it, small, very broad, concave; the two innermost very oblique, and more or less divided into two unequal lobes." The best known genus is Impatiens.

BALSAMODENDRON (from balsamon—an old Greek word used by Theophrastus—balm or balsam, and dendron, a tree). ORD. Burseraceæ. Greenhouse or stove balsamiferous trees. Flowers small, green, axillary, often unisexual; calyx four-toothed, permanent; petals four, linear-oblong, induplicately valvate in æstivation; stamens eight, inserted under the annular disk, having elevated warts between them. Berry, or drupe, ovate,[155] acute, one to two-celled, marked with four sutures. Leaves with three to five sessile, dotless leaflets. They thrive in a compost of thoroughly drained sandy loam. Propagated by cuttings of ripe young wood, taken in April, and placed under a hand glass, in bottom heat. The species named below doubtfully belongs to this genus, as the characteristics above enumerated will show.

> B. zeylanicum (Ceylon).* fl. white, three-petaled, glomerated, involucrated; racemes interrupted, downy. l. impari-pinnate, with five to seven-stalked, ovate, acute leaflets. h. 30ft. Ceylon.

FIG. 203. BAMBUSA AUREA.

BAMBUSA (from bambu, the Malay name). Bamboo Cane. ORD. Gramineæ. A genus of ornamental, shrubby, greenhouse, half-hardy or hardy shrubs, each culm flowering but once. Flowers usually hexandrous. Leaves, as a rule, relatively shorter than the stems, lanceolate, and narrowed at the base. Stems jointed, flexuose, branching, usually hollow, and, when mature, of a hard, woody nature. In well drained, sheltered situations, in the open, with rich, loamy soil, some of the species make extremely graceful objects, particularly so in the more southern counties of England, and in parts of Scotland. Unless a very severe winter is experienced, they may be left without protection. Plants of all the species, however, should have the shelter of a cold greenhouse till about the end of April; when they should be gradually hardened off, and transferred to a warm, sheltered spot, such as in woodlands, by the margins of lakes, &c., as they like plenty of moisture during the summer. A good watering must be given after planting, to settle the soil. Propagation is effected by careful division of well-developed plants, which should be done in early spring, just as new growth is commencing; and it is advisable to establish the divisions in pots. See also Arundinaria.

FIG. 204. BAMBUSA NANA.

> B. arundinacea (reed-like).* Stem very stout, rising like a beautiful column to some 50ft. or 60ft. in height; the laterals producing a profusion of light green leaves, the whole presenting the appearance of a huge plume of feathers. India, 1730. This species is best treated as a stove plant, but it may be placed out of doors in summer. See Fig. 202. (B. F. S. 321.)

> B. aurea (golden).* l. lanceolate, acute, light green, distinguished from B. nana by having their under surface less glaucescent, and the sheath always devoid of the long silky hairs. China. This very handsome species forms elegant tufts, with its slender much-branched stems, which attain a height of from 6ft. to 10ft., and are of a light green colour in a young state, ultimately changing into a yellowish hue. Hardy in most parts of the country. See Fig. 203.

> B. Fortunei (Fortune's).* l. linear-lanceolate, abruptly pointed, somewhat rounded at the base, on very short hairy stalks, serrated and often fringed with long hairs on the margin, downy on both sides, and distinctly variegated, the transverse veins often of a bottle-green colour. h. 1ft. to 2ft. Japan. A dwarf tufted species, with very slender stem. Quite hardy. There are only variegated varieties of this in cultivation, viz., variegata and argenteovittata. (F. d. S. 1863, t. 1535.)

This[156] vigorous-growing species can be cultivated out of doors during summer, and, in most localities, it may be left out all the year.

> B. nana (dwarf).* l. lanceolate, acute, glaucous, stoutish, with the footstalks slightly downy. h. 6ft. to 8ft. India, 1826. A rather tender species, requiring to be grown in the stove or greenhouse. SYNS. B. glauca and B. viridi-glaucescens. See Fig. 204.

> B. nigra (black). See Phyllostachys nigra.

> B. Ragamowski (Ragamowsk's).* l. 9in. to 18in. long, and about 1in. to 3in. broad. China and Japan. This species "can readily be recognised by the tomentose line on one side of the midrib, running nearly the whole length of the leaf on the underside, this line being always on the longer side of the leaf."

BANISTERIA (named after John Baptist Banister, a traveller in Virginia in the seventeenth century, author of a catalogue of Virginian plants, inserted in Ray's "Historia Plantarum"). ORD. Malpighiaceæ. Stove trees or shrubs, frequently climbing. Flowers yellow; calyx five-parted; petals furnished with long stalks; stamens ten. Leaves simple, stalked. They are for the most part very ornamental, but are not often seen in flower in this country. They will grow in a mixture of loam, leaf soil, and peat, with some sharp sand added. Cuttings, made from ripened wood, will root freely in sandy soil, under a hand glass, in stove heat, taking about three or four weeks to do so.

BANKS. These are usually formed with a view to increasing the amount of surface ground, and for the acceleration or retarding of vegetable crops, such as strawberries, &c. They should be from 6ft. to 12ft. apart, according to the depth of soil, and run from east to west. In constructing Banks of a uniform size, great care, and a constant use of the garden line, will be found necessary. For the warmest side of the Banks, Dwarf French Beans, Peas, Vegetable Marrows, Cucumbers, New Zealand Spinach, Capsicums, &c., may be grown. On the opposite side, and when a prolonged supply is desired, Cauliflower, Broccoli, Lettuce, Turnip, Spinach, &c., may be sown thinly in drills, to be thinned out, and remain. It needs but little discretion to produce valuable crops by this method.

BANKSIA (named in honour of Sir Joseph Banks, once President of the Royal Society, and a distinguished patron of science, particularly of Natural History). ORD. Proteaceæ. Greenhouse evergreen shrubs, natives of Australia, principally grown for the beauty of their foliage. Leaves variable in form, usually dark green, clothed with white or rufous down beneath; margins deeply serrated or spinous, rarely entire. The following is the mode of culture recommended many years ago by Sweet. The pots should be well drained, by placing a potsherd about half way over the hole at the bottom of the pot, then laying another piece against it that it may be hollow, afterwards putting some smaller pieces all around them, and on the top of these some others broken very small. All the plants belonging to the order Proteaceæ should be drained in a similar manner, as the roots are very fond of running amongst the broken potsherds, and consequently there is less danger of their being overwatered. Care must also be taken not to allow them to flag, as they seldom recover if once allowed to get very dry. The plants should be placed in an airy part of the house when indoors. Cuttings are generally supposed to be difficult to root, but this is not the case if properly managed. Let them be well ripened before they are taken off; then cut them at a joint, and place them in pots of sand, without shortening any of the leaves, except on the part that is planted in the sand, where they should be taken off quite close. The less depth they are planted in the pots the better, so long as they stand firm when the sand is well closed round them. Place them under hand glasses in the propagating house, but do not plunge them in heat. Take the glasses off frequently to give them air, and dry them, or they will probably damp off. When rooted, transfer to small pots; after which, place them in a close, unheated frame, and harden by degrees. Seeds are a very unsatisfactory means of multiplying the stock.

June. l. entire, oval-oblong, acuminated, shining. h. 30ft. Sierra Leone, 1793. (L. B. C. 367.)

BAPTISIA. (from bapto, to dye; so named from the economical use of some of the species). ORD. Leguminosæ. North American hardy herbaceous plants, with trifoliate, rarely simple leaves, and racemes of yellowish or blue flowers. They are somewhat shy bloomers, but grow freely in a loamy soil.

BARBACENIA. (named after M. Barbacena, a Governor of Minas Geraes). Formerly placed in ORD. Hæmodoraceæ, but now referred by Bentham and Hooker to Amaryllidaceæ. Very singular and pretty stove evergreen herbaceous perennials, allied to Vellozia. Flowers purple, large, showy; perianth funnel-shaped, resinosely hairy on the outside; limb spreading; scapes one-flowered, usually clothed with glandular hairs. Leaves firm, spiral, spreading, acutely keeled. Lindley says that they are capable of existing in a dry, hot air without contact with the earth, on which account they are favourites in South American gardens, where, with Orchids and Bromeliads, they are suspended in the dwelling houses, or hung to the balustrades of the balconies, in which situation they flower abundantly, filling the air with their fragrance. They are rarely seen in our gardens. They may be grown in baskets of fibrous loam and peat, with some nodules of charcoal added.

FIG. 205. FLOWER OF BARBACENIA PURPUREA.

> B. purpurea (purple).* fl. funnel-shaped, six-cleft, terminal, solitary; ovarium elongated, tuberculated. July. l. linear, keeled, with spiny serratures. h. 1½ft. Brazil, 1825. See Fig. 205. (B. M. 2777.)

BARBADOS CHERRY. See Malpighia.

BARBADOS GOOSEBERRY. See Pereskia aculeata.

BARBADOS LILY. See Hippeastrum equestre.

BARBAREA (anciently called Herb of St. Barbara). Winter Cress; American Cress. ORD. Cruciferæ. Hardy glabrous perennial herbs. Flowers yellow; racemes erect, terminal. Stems erect. They are of easy culture, but scarcely worth growing in the pleasure garden. Propagated by cuttings, suckers, divisions, or seeds.

Here and there on roadsides, and in dry gravelly places in Great Britain. An escape from cultivation. (Sy. En. B. 124.)

> B. vulgaris (common). l., lower ones lyrate; terminal lobe roundish; upper ones obovate, toothed, or pinnatifid. h. 1¼ft. The double flowering form of this native species is the only one of this genus worth growing for beauty; it is generally known as Double Yellow Rocket. The variegated form is also rather pretty, and comes true from seed. (Sy. En. B. 120.)

BARBATUS. Having long weak hairs, in one or more tufts; bearded.

BARBERRY. See Berberis.

BARBIERIA (in honour of J. B. G. Barbier, M.D., a French physician and naturalist, author of "Principes Generaux de Pharmacologie ou de Matière Medicale," Paris, 1806). ORD. Leguminosæ. An ornamental stove evergreen, requiring a mixture of peat, loam, and sand. Propagated by cuttings of half-ripened wood, which should be placed in sand, under a glass, in stove heat.

> B. polyphylla (many-leaved).* fl. scarlet, 2in. long; racemes axillary, few-flowered, shorter than the leaves. l. impari-pinnate, with nine to eleven pairs of elliptic-oblong, mucronate leaflets, pubescent in an adult state. Porto Rico, 1818. SYNS. Clitorea polyphylla and Galactia pinnata.

[158]

BARBS. Hooked hairs.

BARK. The outer integuments of a plant beyond the wood, and formed of tissue parallel with it.

BARK-BOUND. This condition is generally the result of very rich soil, or insufficient drainage. In most fruit trees a gummy exudation takes place. If caused by stagnancy, thorough drainage should immediately be effected. Scrubbing the stem is also recommended. Slitting the bark with a knife is likely to do more harm than good, particularly so in the hands of the inexperienced.

BARKERIA (name commemorative of the late G. Barker, of Birmingham, an ardent cultivator of orchids). ORD. Orchidaceæ. From a scientific point of view, this genus should be included in Epidendrum. Very handsome, deciduous, epiphytal, cool-house orchids, having slender pseudo-bulbs, from 6in. to 12in. high, from the top of which the numerous flower-stems are produced. In a cool, airy temperature, these plants grow vigorously, suspended in pans or small baskets close beneath the glass, and slightly shaded with tiffany. They succeed well also on flat blocks of wood, on the top of which they should be tied, without any moss, as their freely-produced, thick, fleshy roots soon cling to the blocks. During the season of growth, a good supply of water is needed, and in hot weather it may be applied three or four times daily; the blocks and plants are best immersed in water; but when at rest, a slight watering twice or three times a week will suffice. Propagated by divisions, just previous to the commencement of new growth.

> B. elegans (elegant).* fl. in loose racemes, four or five in each; each blossom about 2in. across; sepals and petals dark rose; lip reddish crimson, spotted and edged with a lighter colour. Winter. h. 2ft. Mexico, 1836. Of this beautiful slender-growing species, there are two or three varieties in cultivation. (B. M. 4784.)

> B. Lindleyana (Lindley's).* fl., raceme 2ft. long, very slender, bearing from five to seven blossoms near its apex; sepals and petals rosy purple; lip white, with a deep purple blotch at its apex. September, remaining in beauty for a considerable time. h. 2ft. Costa Rica, 1842. (B. M. 6098.)

> B. L. Centeræ (Center's).* fl. rosy lilac; lip oblong; margins crenulated or crisped; apex blotched deep purple. Costa Rica, 1873.

> B. melanocaulon (dark-stemmed).* fl. on an erect spike; sepals and petals rosy lilac; lip broader at the base than at the top, reddish-purple, having a blotch of green in the centre. August. h. 1ft. Costa Rica, 1848. Very rare.

> B. Skinneri (Skinner's).* fl. deep rose-coloured; spikes 6in. to 9in. long, from the apices of the ripened growth, often branched, forming a dense mass of deep purple blossoms, which, if kept dry, lasts from eight to ten weeks. h. 1½ft. Guatemala. (P. M. B. 15, 1.)

> B. S. superbum (superb).* fl. dark rose; lip somewhat deeper tinted, and marked towards the base with yellow streaks. Guatemala. This far surpasses the type in size and number of flowers, as well as in brilliancy of colour. (W. S. O. 38.)

> B. spectabilis (showy).* fl. quite 2in. across, produced eight or ten together, on a spike issuing from the top of the pseudo-bulb; sepals and petals oblong, acuminate, rosy lilac; lip white, margined with deep lilac or rosy purple, and dotted or spotted with crimson. This very distinct and desirable species lasts from eight to ten weeks in beauty, and forms a very handsome object when placed in the drawing-room and covered over with a large glass shade. Guatemala, 1843. (B. M. 4094.)

BARKING-IRONS. Instruments used in taking off the bark of trees.

BARKLYA (named after Sir H. Barkly, formerly Governor of South Australia). ORD. Leguminosæ. A large greenhouse tree, thriving in a compost of loam and leaf mould. Propagated by seeds and cuttings; the latter should be half ripened, and placed in sandy soil, under a bell glass, in a cool house.

> B. syringifolia (Syringa-leaved). fl. golden yellow, numerous, disposed in axillary or terminal racemes. l. alternate, simple, coriaceous. h. 30ft. Moreton Bay, 1858.

BARK STOVE. A hothouse adapted for moisture-loving exotics, and having a pit from 2ft. to 4ft. deep, containing fermenting matter, chiefly tanners' bark, by which means a steady heat is maintained for a considerable time. The Bark Stove is now almost obsolete. Bark is, however, still largely used in pine pits, and in some propagating beds; but such beds are generally superseded by hot-water or hot-air tanks.

BARLERIA (named after J. Barrelier, a French botanist of the seventeenth century). ORD. Acanthaceæ. A genus of interesting and ornamental stove evergreen shrubs. Flowers axillary or terminal; calyx four-sepaled, the two outer larger than the others. They thrive best if grown in loam and peat, with a little rotten dung added. Propagated by cuttings made of the young wood, and placed in a similar compost, under a bell glass, in stove temperature, with bottom heat.

They should be grown in peat, loam, and sand, in equal proportions. Propagated either by seeds, sown in hotbeds in March, or by cuttings, made of half-ripened wood in April, and placed in sand under a bell glass.

FIG. 206. BARNADESIA ROSEA.

[159]

> B. rosea (rosy).* fl.-heads rose-coloured, solitary, ovate-cylindrical, downy, sessile; florets bilabiate, one lip oblong-emarginate, villous, the other filiform; hairs on receptacle twisted; pappus stiff, plumose. May. l. alternate, ovate, acute at both ends. h. 1½ft. South America, 1840. See Fig. 206. (B. M. 4232.)

BARNARDIA. Included under Scilla (which see).

BAROMETER. An instrument for measuring the density of the atmosphere, and hence determining the probable changes of weather, or the height of any ascent. To the gardener the Barometer is indispensable as a warning to take due precaution.

BAROSMA (from barys, heavy, and osme, smell; referring to the powerful scent of the leaves). Name often incorrectly spelt Baryosma. SYN. Parapetalifera. ORD. Rutaceæ. Very pretty small, Heath-like, greenhouse evergreen shrubs, from the Cape of Good Hope. Calyx equally five-parted; petals five, oblong; stamens ten. Leaves opposite or scattered, coriaceous, flat, dotted, with their margins sometimes glandularly serrulated, sometimes almost entire or revolute. They thrive in a mixture of sand, peat, and a little turfy loam, with good drainage and firm potting. Cuttings, taken from ripened wood, inserted in a pot of sand, and placed in a shady position in a cool house, with a bell glass over them, will root readily in a few weeks.

> B. betulina (Birch-leaved). fl. white, axillary, solitary. February to September. l. opposite, obovate, serrulate, sessile, spreading. h. 1ft. to 3ft. 1790. (B. M. Pl. 45.)

> B. latifolia (broad-leaved). fl. white, usually solitary, lateral. July. l. opposite, ovate-oblong, sessile, serrulated, smoothish, without glandular dots; branches villous. h. 1ft. 1789.

> B. pulchella (pretty).* fl. pale red or purple; peduncles axillary, usually solitary, exceeding the leaves. February. l. crowded, ovate, quite smooth, with thickened, crenate-glandular margins. h. 1ft. to 3ft. 1787.

BARRED. Marked in spaces with a paler colour, resembling bars.

BARREN FLOWERS. The male or staminate flowers of many plants, such as the Cucumber, Melon, &c., are popularly known as Barren Flowers, i.e., they produce no fruit. This condition is, in some respects, similar to "blind" Strawberries or "blind" Cabbages, so far as fruition is concerned, but structurally and functionally it is widely different. The Barren Flowers of the Cucumber, Melon, &c., are produced by what are known as monœcious plants, i.e., having male and female organs in different flowers, but on the same plant. In the Strawberry, &c., Barren Flowers are generally the result of unfavourable surroundings, or unskilful cultivation. A good example of Barren Flowers is seen in the ray-florets of many Composite plants, which are frequently really neuter, having neither male nor female organs.

BARREN SOILS. A term signifying such soils as are normally unprofitable. The term can only be correctly applied in very few cases; as almost any soil may be rendered capable of affording a basis for some kind of vegetable life, arboreal or other. The question of planting up the enormous quantity of what is now waste land, might well engage the most practical consideration. Of course, the natural state of any land will, to a great extent, determine what would be its ultimate condition, after all that could be effected by mechanical agency has been accomplished. Drainage, irrigation, enrichment, pulverisation, are all matters which can only be considered upon a particular basis; but we doubt not that the thousands of acres of land now practically almost useless, might, by the adoption of proper means, be rendered fairly remunerative.

BARREN-WORT. See Epimedium.

BARRINGTONIA (named after the Hon. Daines Barrington, F.R.S.). ORD. Myrtaceæ. A genus of stove evergreen trees and shrubs, very difficult to cultivate. Flowers large, racemose. Leaves opposite or whorled, generally obovate; margins toothed or entire. Fruit one-seeded, fleshy. They require a compost of two parts loam, one peat, and one sand. Water should be given in abundance, and a moist atmosphere at all times maintained, the temperature ranging from 65deg. to 95deg. Propagated by cuttings obtained from the lateral shoots; these, taken off at a joint when the wood is ripe, planted in sand, with a hand glass over them, root readily. The cuttings should not be stripped of any of their leaves.

> B. racemosa (raceme-flowered). fl. red; racemes pendulous, very long. l. cuneate-oblong, acuminated, serrulated. h. 30ft. Malabar, 1822. (B. M. 3831.)

> B. speciosa (showy).* fl. purple and white, large and handsome, disposed in an erect thyrse. l. shining, cuneate-oblong, obtuse, quite entire. h. 20in. to 30in. in England. This beautiful species seldom attains a height of more than 6ft. or 8ft. (G. C. 1845, p. 56.)

BARROW. Garden Barrows are very numerous, both with and without wheels. The Flower-pot Barrow has a wheel and a flat surface, on which plants, pots, or leaves are placed, either directly, or, when small, in shallow baskets. The Haum Barrow is an open box or case, of wicker or other work, placed on, or suspended from, a pair of handles, with or without a wheel, and is useful for carrying litter, leaves, &c. The Water Barrow, instead of a box, contains a barrel, tub, or cistern, in which fluid manure, or ordinary water, is conveyed to different parts of the garden. The Hand-barrow is a frame of wood, carried by two levers, which form four handles; for removing large pots or tubs of trees or shrubs it is very useful.

FIG. 207. FLOWER OF BARTONIA AUREA.

BARTLINGIA. A synonym of Plocama (which see).

BARTONIA (in honour of Benjamin S. Barton, M.D., formerly Professor of Botany at Philadelphia). ORD. Loasaceæ. Hardy annuals or biennials, downy, with stiff and bearded hairs. This genus is now placed under Mentzelia in most standard botanical works. Flowers white or yellow, large, terminal, expanding in the evening, when they are very fragrant, and becoming reddish as they fade. Leaves alternate, interruptedly pinnatifid. The species are very showy, and well worth growing. Any ordinary garden soil suits them. Seeds should be raised in a gentle heat in spring;[160] and, when the seedlings are sufficiently large, they should be potted singly into small, well-drained pots. In winter, they should be placed on a dry shelf in a greenhouse or frame. B. aurea is one of the brightest of hardy annuals, and may be sown either in a frame, or in the open border in April.

> B. albescens (whitish).* fl., petals ten, pale yellow, disposed in a leafy panicle. July. l. sinuately toothed. Stem with a white shining epidermis. h. 1ft. to 4ft. Chili, 1831. Annual or biennial. (S. B. F. G. ii., 182.)

> B. aurea (golden).* fl. two or three together, terminal, bright golden yellow, as large as a half-crown; petals five. June. h. 1ft. California, 1834. Annual. See Fig. 207. (B. M. 3649.)

> B. nuda (naked) and B. ornata (adorned) are two very pretty white-flowered biennial species. h. 2ft. Missouri, 1811.

BARYOSMA. See Barosma.

BASAL, or BASILAR. Situated at the base of anything; as the embryo, when situated at the bottom of the seed.

BASELLA (its Malabar name). Malabar Nightshade. ORD. Basellaceæ. Annual or biennial stove trailers, with white or pinkish flowers, of no great horticultural value. In India, and elsewhere throughout the tropics, some of the species are cultivated as pot herbs, and are used as a substitute for Spinach.

> B. alba (white).* fl. white. August. l. heart-shaped, pointed. h. 8in. India, 1688. This plant, either when allowed to fall in festoons from the roof of a warm house, or treated as a basket plant, forms an elegant object when in flower.

BASELLACEÆ. A series of usually herbaceous climbers, and considered a tribe of Chenopodiaceæ.

BASIL, SWEET (Ocymum basilicum). This is a tender annual from India, and must be raised in gentle heat. The foliage is somewhat largely used for flavouring purposes. Seeds should be sown in April, the seedlings pricked out into boxes to strengthen, and finally planted out about 8in. asunder, in beds of light rich soil, in June, being well watered until fully established. As soon as they bloom, they should be cut down to within a few inches of the ground, and the portions cut off should be tied up in small bunches and dried in the shade for winter use. Some of the plants can be lifted in September, potted up, and placed in a warm greenhouse for the winter, when the fresh green leaves will be found very useful. Bush Basil (Ocymum minimum) is a dwarfer plant, but may be treated in the same way. Wild Basil is botanically known as Calamintha Clinopodium.

BASIL-THYME. See Calamintha Acinos.

BASI-NERVED. When the nerves of a leaf spring from the base.

BASING-UP. The raising of a small bank of earth entirely round a plant, so as to retain water immediately about the root. The term is sometimes used to signify Earthing or Moulding, which see.

BASKETS. Few objects contribute more to the adornment of a window, or the decoration of the diningroom, drawing-room, or glass-house, than Hanging Baskets, tastefully filled with handsome foliaged and flowering plants. Baskets are made in different forms and of various materials, such as wire, terra-cotta, wood, and cork. The Wire Baskets have a very light and elegant appearance, and are generally used. In filling Baskets, the inside should be lined with a thick layer of moss, or Selaginella Kraussiana, next to which a layer of coarse sacking must be placed, to prevent the soil from working through. Terra-cotta Baskets are very pretty, and are extensively employed in domestic rooms, but they should always have one or more holes at the bottom, to facilitate drainage. Rustic Baskets, of cork or wood, are also very suitable for floral arrangements; those composed of teak-wood are very generally used for orchids. The compost should be prepared according to the requirements of the plant or plants intended to be grown, which can be easily ascertained on reference to such plants in this work. The soil should not be allowed to get dry; in the event of this happening, however, a thorough soaking by immersion must be given. As a rule, attention should be given in the matter of watering every other day, and light syringing every morning and evening during the spring and summer months will be most beneficial. The Baskets should be examined every week, all dead or decaying leaves being removed, and any insects, which are so likely to get a foothold, destroyed. In arranging the subjects, the centre plant should be the tallest, the next outer ones shorter, and the marginal ones of a trailing or drooping habit, so that the whole may present a symmetrical, and at the same time a natural, appearance. Wickerwork Baskets are used for carrying or transferring plants, and are generally made 18in. wide by 20in. deep; they are extremely useful, and should be in every garden. Split wood and withes are largely employed in making Baskets. The Planter's Basket, described by Loudon as a flat, rectangular utensil of wickerwork or boards, partitioned into three or more parts, for the purpose of carrying with the gardener when about to plant or remove plants, is now, unfortunately, almost obsolete. One division is for the plants, another for those taken up, and a third for the tools to be made use of, and for any decayed parts of plants, stones, weeds, or other refuse which may be collected. By using this Basket, order, accuracy, and neatness are secured. The Sussex "Truck" Baskets, made of willow-wood, are very useful, being both light and durable. See also Measures.

BASSIA (named after Ferdinando Bassi, Curator of the Botanic Garden at Bologna). ORD. Sapotaceæ. Handsome lofty-growing lactescent stove trees, with axillary, solitary, or aggregate flowers, and quite entire, smooth, coriaceous leaves. They require stove heat, and a compost of peat and loam. Cuttings, taken from ripened wood, strike readily in sand, under a hand glass, in a strong moist heat.

> B. butyracea (buttery). The Indian Butter Tree. fl., pedicels aggregate, and are, as well as the calyces, woolly. l. obovate, 8in. to 9in. long, and 4in. to 5in. broad, tomentose beneath. h. 30ft. to 70ft. Nepaul, 1823. (B. F. F. 35.)

> B. latifolia (broad-leaved). The Mahwah Tree of Bengal. fl., corolla thick and fleshy; pedicels drooping, terminal. l. oblong or elliptic, smooth above, whitish beneath, 4in. to 8in. long, and 2in. to 4in. broad. h. 50ft. India, 1799. (B. F. S. 41.)

> B. longifolia (long-leaved). fl., pedicels axillary, drooping, crowded round the ends of the branchlets. l. ovate-lanceolate, approximate at the tops of the branches, 6in. long, deciduous. h. 50ft. Malabar, 1811. (B. F. S. 42.)

BASS or BAST MATS. These are prepared, chiefly in Russia, from the inner bark of various Limes (Tilia), and are very largely used in this country by nurserymen for packing purposes. They are also extensively employed as coverings, being excellent preventatives of the effects of frost. They are beneficial as a covering for beds of early vegetables, to prevent radiation during the night. For tying purposes they are now greatly superseded by Raffia Grass. Archangel Mats are larger, and of better quality than the St. Petersburgh. Dunnage Mats are heavy, and generally used for covering, as they are much cheaper.

BATATAS (its aboriginal name). ORD. Convolvulaceæ. This genus is now referred to Ipomæa. Strong, free-growing, greenhouse or stove deciduous twiners. Calyx of five sepals; corolla campanulate; stamens inclosed. They are of easy culture, only requiring plenty of room to spread, and are well adapted for trellis work, or to run up pillars. They are all tuberous rooted, and therefore require to be kept dry when in a dormant state. A rich, open, loamy soil is most suitable. Young cuttings strike readily under a hand glass, in heat.

> B. bignonioides (Bignonia-like).* fl., corolla dark purple, funnel-shaped, with a curled limb; peduncles many-flowered, nutant, shorter than the petioles. July. l. three-lobed; hind lobes rounded, imbricate. Cayenne, 1824. (B. M. 2645.)

> B. paniculata (panicled).* fl. large, purple; peduncles much exceeding the petioles, many-flowered, dichotomously and corymbosely panicled. June l. palmate, five to seven-cleft; lobes ovate-lanceolate or elliptic, bluntish, rarely sub-acuminated. India, 1799. (G. C. n. s., x., 341.)

> B. senegalensis (Senegalese). fl. white or purplish, large; peduncles three-flowered. June. l. quinately palmate; lobes ovate, obtuse, middle one the largest. Stem white, tubercular. Guinea, 1823.

> B. venosa (veiny). fl. purple; peduncles umbellate, with an ovate-cordate, solitary leaf at the base of each pedicel. July. l. digitately quinate; leaflets petiolate, acuminated, quite entire. France, 1820.

BATEMANNIA (named after Mr. J. Bateman, a collector and cultivator of orchids, and author of a "Monograph of Odontoglossum," and other works on orchidaceous plants). ORD. Orchidaceæ. A small and easily-grown genus of dwarf, compact-growing epiphytes, closely allied to Maxillaria, but differing from that genus in having the anther-bed with a membranous border. They may be grown in pots, in a compost of peat and moss, or on blocks of wood with moss. They require an intermediate house and plenty of water in the growing season. Propagated by divisions and offsets. They have generally a free-flowering habit; but some of the species are not so ornamental as many other orchids.

> B. armillata (braceleted). fl. green, white. 1875. (R. X. O. 316.)

> B. Burtii (Burt's). fl. red-brown, yellow base, 3in. across; lip white, tipped chocolate. Autumn. l. elliptic-oblong, or ligulate, sub-distichous. Plant bulbless. Costa Rica, 1872. (B. M. 6003.)

> B. Colleyi (Colley's). fl. on a pendulous raceme, rising from the base of the pseudo-bulbs; sepals and petals brownish-purple within, green without; lip white. Autumn. h. 6in. Demerara, 1834. (B. R. 1714.)

> B. grandiflora (large-flowered).* fl., flower-spike coming up with the young growth, bearing three or four flowers, of curious structure; sepals and petals olive-green, striped with reddish-brown; lip white, with reddish-purple streaks, orange or yellow towards the base. Pseudo-bulbs ovate, 3in. or 4in. long, and bearing two large, broad, leathery leaves. New Grenada, 1866. (B. M. 5567.)

> B. Wallisii (Wallis').* fl., sepals light greenish-yellow outside, olive-green to chestnut-brown inside, with some yellow at the base; petals with scarlet stripes at the very base, but otherwise coloured like the sepals; lip blade greenish, with a brownish hue at the anterior part; peduncles slender, corymbose. h. 1ft. Columbia, 1876.

BATSCHIA. See Lithospermum.

BAUERA (named after Francis and Ferdinand Bauer, German botanical draughtsmen). ORD. Saxifragaceæ. Small shrubs, natives of Australia, New Zealand, &c. Flowers axillary, solitary, pedunculate. Leaves six in a whorl, approximating by threes, and therefore, as it were, opposite and ternate, exstipulate. Easily cultivated in a compost of sandy loam and peat. Propagated by cuttings, placed in sandy soil, under a glass. These very pretty little greenhouse evergreens flower nearly the whole year through.

> B. humilis (low). fl., corolla red, one-half smaller than B. rubioides, and the plant is altogether much smaller. July to December. l. oblong, crenated. h. 1ft. New South Wales, 1804. (L. B. C. 1197.)

> B. rubiæfolia (madder-leaved). Synonymous with B. rubioides.

> B. rubioides (madder-like).* fl. pale red, or pink. l. lanceolate, crenated. h. 1ft. to 2ft. New South Wales, 1793. SYN. B. rubiæfolia. (A. B. R. 198.)

BAUHINIA (in honour of John and Caspar Bauhin, two famous botanists of the sixteenth century). Mountain Ebony. ORD. Leguminosæ. Very showy stove evergreen shrubs. Flowers racemose; petals five, spreading, oblong, rather unequal, upper one usually distant from the rest. Leaves two-lobed, constantly composed of two jointed leaflets at the top of the petiole, sometimes nearly free, but usually joined together, more or less, and with an awn in the recess. They succeed well in a mixture of sand, loam, and peat, requiring good drainage and moderately firm potting. Propagated by cuttings, which should be taken when the wood is neither very ripe nor very young; the leaves must be dressed off, and the cuttings planted in sand, under a glass, in moist heat. Although glorious objects in the tropics, few of the species flower under our comparatively sunless skies; those which hitherto have succeeded well in Britain are marked with an asterisk.

[162]

> B. acuminata (taper-pointed-leaved). fl. pure white; petals broadly ovate, hardly stipitate. June. l. rather cordate at the base, smoothish; leaflets connected beyond the middle, ovate, acuminated, parallel, four-nerved. h. 5ft. to 6ft. Malabar, 1808.

BAWD-MONEY. See Meum.

BAY-TREE. See Laurus nobilis.

BEAK. Anything resembling the beak of a bird, as in Aconitum; the point which ends the helmet or upper sepal; hard, sharp points.

BEAM TREE. See Pyrus Aria.

BEAN BEETLE (Bruchus granarius). This insect, by depositing its eggs in the seeds of Beans and Peas, causes a great amount of injury. It is about an eighth of an inch long, black, with brown hairs and white spots; tip of the tail prolonged, downy; front pair of legs reddish. The most effectual means of prevention is to destroy, when sowing, all seeds infested by it; and this may be detected by the skin of the seed being unusually transparent above the tunnel for exit. Imported seeds of Broad Beans are often much infested. "Dipping the Beans or Peas in boiling water for one minute is stated to kill the grub inside; but, as dipping for four minutes generally destroys the germinating power, the experiment is much too hazardous for general use", (Ormerod).

BEAN CAPER. See Zygophyllum.

BEAN FLY. See Aphides and Black Fly.

BEANS. There are three sections of these in cultivation for garden purposes, viz.: The Dwarf or French Bean; the Climbing, or Scarlet Runner; and the ordinary Broad Bean. See also Faba and Phaseolus.

FIG. 209. BROAD BEAN PLANT IN FLOWER (FABA VULGARIS).

Soil. All Beans like a somewhat loamy soil, which, to secure good crops, must be deeply worked and heavily manured. The Kidney Beans, dwarf and tall, however, do not care for so heavy a soil as the Broad and Long-podded kinds; and this fact should be borne in mind when selecting their respective situations. The term Kidney is generally applied to both the Dwarf or French and the Climbing or Scarlet Runner.

FIG. 210. PODS OF BROAD BEAN.

FIG. 211. BROAD BEAN SEED.

[163]

BROAD AND LONG-PODDED (Faba vulgaris). Cultivation: As early as possible in the autumn, deeply trench a piece of ground, and work in a heavy dressing of manure, leaving the surface of the soil in ridges, to become well aërated by winter frosts. Where desired, a piece of ground on a warm, protected border, can also be deeply dug in November, and a few rows of Mazagans sown to stand the winter. When up, draw a ridge of soil on either side the rows, and in frosty weather strew a few handfuls of bracken, or other light, dry litter, over them. Not much is, however, gained by this winter sowing. Early in January, level the ridges with a fork, working the whole of the surface soil over, and towards the end of the month, make the first sowing, choosing Mazagan and other early varieties. Mark out two rows, 9in. asunder, leave a space of 30in., then another two rows, and so on throughout the piece sown. If preferred, they may be sown in single rows at intervals of 1½ft. The drills should be about 3in. deep, and the seed from 7in. to 9in. apart in the rows. Where the double-row system is adopted, arrange the seed for the plants to come alternately. In March, get in the main sowing of the Broad and later Long-podded kinds, in the manner already described; another sowing for late use may be made in April. When the plants are about 6in. high, earth up as recommended for those sown in the autumn. As soon as a good crop is set, pinch out the tops of the plants, to assist the maturation of the Beans, and prevent the attacks of the fly. Figs. 209, 210, and 211 are excellent representations of the flowering plant, pods, and seed of the Broad Bean.

Sorts. For early use: Early Mazagan, Long-pod, Marshall's Early Prolific, and Seville Long-pod. For late use: Carter's Mammoth Long-pod, and Broad Windsor (white variety). These are all distinct and good varieties.

FIG. 212. FRUITING PLANT OF DWARF OR FRENCH BEAN (PHASEOLUS VULGARIS).

DWARF OR FRENCH KIDNEY BEANS (Phaseolus vulgaris). Cultivation: This class (see Fig. 212) also requires a rich and deeply trenched rather light soil. A very important point is to get the ground into a good condition, by frequently forking it over; and, as the seeds are not sown till the beginning of May, there is plenty of time for the work. The finer the soil is, and the more it is aërated, the better will it suit the crop. From the beginning of May till the end of June, at intervals, draw out drills about 2ft. apart, and 3in. deep, and in these place the Beans tolerably thick, as generally they are not all certain to grow. As soon as up, carefully thin them, and slightly earth up to prevent the wind blowing them about. They should not, however, be earthed higher than the seed leaves, or they will probably rot off in wet weather. Keep free from weeds, and maintain a sharp look out for slugs. In dry weather, water occasionally, giving good drenchings, and not mere sprinklings, which do more harm than good. A good mulching of half-rotted manure is very beneficial, as it prevents evaporation to a great extent, besides affording some amount of nourishment to the plants. Great care must be taken to pick off the Beans as soon as large enough for use, or they will exhaust the plants. Where seeds are needed, a number of plants should be left for the purpose, and these should be some of the best, to prevent deterioration, or loss of the true variety.

Forcing. French Beans require more heat than can be obtained in either a frame or an ordinary greenhouse; and, although easy enough to grow in a structure suited to their requirements, yet, if such does not exist, they are almost sure to fail. A good heat, from 60deg. to 70deg., with abundance of moisture, is necessary for successful results. Plenty of light is also most essential. A position such as that of a cucumber house is generally a suitable one; but the plants must not be placed under the cucumbers. Successional sowings in pots or boxes must be made, from the end of August till March, to keep up a supply. For soil, use good maiden loam, with a little well-rotted manure added. Use 8in. pots, sowing five or six beans in each. The first sowing should be placed in a frame and kept well watered, bringing into heat in October; but the subsequent sowings should be placed directly in the house. Keep the soil moist, and the plants free from aphides and other insect pests, and give air at every favourable opportunity. The plants should be as near the light as possible, and kept from falling about by tying or placing small pieces of Birch wood round them. In dull weather, it will be found that the blooms will not set so freely as when the sun shines brightly; therefore, every care should be taken to secure both heat and ventilation when sunshine prevails. When the pots get full of roots, and the plants are bearing fruit freely, a little liquid manure is of great assistance; at no time must the plants get dry enough to flag. Allow plenty of room for the full development of foliage, and maintain a minimum temperature of 60deg., with plenty of moisture.

Sorts. These are very numerous, among the best being Black Negro, Canadian Wonder, Canterbury, Fulmer's Forcing, Golden Dun, Newington Wonder, Osborn's Early Forcing, Sion House, and Sir Joseph Paxton.

RUNNERS OR CLIMBING KIDNEY BEANS (Phaseolus multiflorus). Cultivation: Being tall growers, these need a greater space than the Dwarf French varieties, and they also require support. Rich soil is indispensable for them, and liberal supplies of water on light soils and in dry weather. A good overhead syringing from time to time is also advantageous. Trench and heavily manure a piece of ground in autumn, leaving it in ridges for the winter. In March, level the ridges down, and well work the ground, to render it friable and in good condition. The plants being extremely tender, it is not safe to sow before the end of April or the first week in May. It is preferable to sow in rows, which should be from 6ft. to 12ft. apart, and crop the ground between with other vegetables. Earth up and stake them as soon as ready, to prevent injury from rough wind. A good plan, which may be adopted to obtain early produce, is to raise the seeds in boxes in a cold frame, getting them ready for planting out in the middle of May. Plant at the same distances, and treat afterwards as recommended for those sown out of doors.

If preferred, they can be grown on the ground without stakes. Under this treatment, they must have their tops pinched off when about 18in. high, continuing this pinching from time to time as necessary. If this plan is adopted, the rows need only be 3ft. apart, the ground[164] not being otherwise cropped. In dry seasons and on light soils, there is an advantage attached to this method, namely, that those on sticks are liable to injury from drought, while the foliage of those pinched back keeps the soil moist underneath.

BEAUCARNEA (a commemorative name). ORD. Liliaceæ. A small genus of curious greenhouse plants, natives of Mexico. Leaves narrow, gracefully depending. Stems slender, and woody, with a peculiar swollen, somewhat napiform base. Mr. B. S. Williams recommends that these plants be potted in rich fibrous loam and sand, with ample drainage, and, during the growing season, liberally supplied with water. Propagated by cuttings, when obtainable; but chiefly by seeds, which have to be imported from their native country. Beaucarneas are principally grown for the beauty of their foliage, and are grotesque, graceful, and extremely curious in habit and form.

> B. glauca (grey).* l. pendent, glaucous, 2ft. to 3ft. long. Stem slender, the swollen base becoming woody with age.

> B. g. latifolia (broad-leaved) differs from the type only in its stouter and more robust stem and broader leaves.

> B. longifolia (long-leaved).* l. 6ft. to 10ft. long, narrow, pendent, dark green, forming a beautiful vase-like centre. h. 10ft. Mexico, 1868. Very distinct. (G. C. 1877, vii., 493.)

> B. recurvata (recurved-leaved).* l. very long, linear, gracefully pendulous, bright green. Mexico, about 1845. This is an excellent subject for open-air culture during the summer, as well as for the conservatory. SYN. Pincenictitia tuberculata. (G. C. 1870, 1445.)

> B. r. rubra (red). l. red at base.

> B. stricta (upright). l. 3ft. or more long, less than 1in. broad, very glaucous. Stem stout. Mexico, 1870.

BEAUFORTIA (commemorative of Mary, Duchess of Beaufort, a botanical patroness). Including Schizopleura. ORD. Myrtaceæ. Elegant free-flowering greenhouse Australian shrubs. Flowers scarlet; calyx with a turbinate tube; stamens in bundles opposite the petals. Leaves sessile, opposite or scattered. Beaufortias require a compost of peat, leaf soil, and loam, lightened, if necessary, by the addition of sand. Cuttings of half-ripened shoots root freely in sandy soil, under a glass, with very little heat.

> B. decussata (decussate). fl. scarlet; bundles of stamens on very long claws; filaments radiating. May. l. opposite, decussate, ovate, or oval, many-nerved. h. 3ft. to 10ft. New Holland, 1803. (B. M. 1733.)

> B. purpurea (purple).* fl. purplish-red, in dense globular heads. l. three to five-nerved, erect or spreading, ovate-lanceolate to lanceolate-linear. New Holland.

> B. sparsa (few-leaved). fl. bright scarlet. l. many-nerved, scattered, ovate-elliptical, obtuse. West Australia. SYN. B. splendens. (P. F. G. xiii., 145.)

> B. splendens (splendid). Synonymous with B. sparsa.

BEAUMONTIA (in honour of Mrs. Beaumont, formerly of Bretton Hall, Yorkshire). ORD. Apocynaceæ. A very ornamental stove twiner, remarkable for its handsome flowers. It succeeds best when planted out in the borders of a temperate house, in rich lumpy loam and peat. Propagated by cuttings, placed in sand, with bottom heat.

> B. grandiflora (large-flowered).* fl., corolla large, white, greenish outside near the base, and dark throat, with a short tube, and a large campanulate five-lobed limb; corymbs axillary and terminal, many-flowered. June. l. opposite, broad, oblong-ovate, with a little point, tapering towards the base, smooth and shining above, but rather downy beneath; young leaves and branches rusty. Chittagong and Sylhet, 1820. (B. M. 3213.)

BED. A term usually applied to pieces of ground laid out in gardens for sowing small seeds, or for the isolation and better protection of small collections of plants in the reserve ground. The oblong is the best shape for this purpose, about 4ft. or 5ft. wide, somewhat raised, and having a narrow path on each side, so that the workman may attend to the plants or seeds without having to tread on the bed. Any one part of a flower-garden design, cut out in grass, or otherwise formed, is also generally termed a Bed. When required to be planted for effect, as in this case, the Bed should be proportionate in size to the plants that are to be put in it, always planting the highest in the centre and gradually sloping, with other sizes, to the edges, which should be the lowest. Circular Beds are best with one centre plant; and oblong or other shapes should have the height of the centre plants carried nearly the whole length, not, however, placing them in too formal a manner.

BEDDING-IN. A method of seed-sowing, now almost obsolete, and chiefly employed in nurseries. "In this method, the ground being dug and formed by alleys into Beds, 4ft. or 5ft. wide, each alley being a spade's width or more between Bed and Bed, and the earth being drawn off the top of the Bed with a rake or spade, ½in. or 1in. deep into the alleys, the seed is then sown all over the surface of the Bed; which being done, the earth in the alleys is immediately cast over the Bed, again covering the seeds the same depth, and the surface is raked smooth" (Johnson). In the case of small seeds, a very light covering is needed, and that only of very fine soil.

BEDDING-OUT. The temporary placing out of doors of greenhouse and other tender plants during the summer months. It is considered by some to be the showiest, most expensive, and most unnatural of any style. The geometrical arrangement of gaudy colours is not at all times satisfactory, and under the most favourable conditions[165] the design is rarely retained more than two or three months, say, from July to September. The method is, however, so extensively adopted as to demand due notice in this work. Bedding usually commences in May. An important consideration is the proper preparation of the soil for the reception of the plants. It will be found to materially assist the growth if the soil is well dug over a fortnight before the plants are put in. By this means, it will acquire a certain amount of solidity, a point of great importance with fibrous-rooted plants that are subject to injury from the fine roots not taking a firm hold of the soil. Having decided upon the arrangement of the plants, proceed to work with the planting. With round, oval, or, indeed, almost any shaped bed, begin in the centre and work towards the edge; in borders, commence at the back and finish with the front row. Plant with a trowel, disturbing the balls as little as possible, and when in the holes press the soil moderately firm. After the Bed is finished, give a good soaking of water to settle the soil at the roots. Manure for Flower-beds should always be perfectly rotten, such as that from a spent hotbed. When the plants are thoroughly established, water must only be given if they show signs of distress; and then a good soaking should be applied. A careful hoeing of the surface after planting will be most beneficial, leaving it smooth and tidy. A Dutch hoe will be the best to use. Injudicious use of manure and water will only cause a foliaceous growth. The proper treatment of the various Bedding Plants will be found under their respective headings. For spring decoration, the Beds may be filled with Dutch bulbs, and spring-flowering annuals and perennials ad infinitum; or, after the plants are removed in autumn, the Beds may be filled with evergreens plunged in pots, such as Aucuba, Arbor vitæ, Euonymus, and various little Conifers, which have a bright appearance through the winter, and can be removed at any time. With the relative value, or advisability of adoption, of either or any system of gardening, it scarcely comes within the province of this work to deal. No hard-and-fast rules can be laid down as regards "style," and each individual may follow his own taste and inclination.

FIG. 214. DESIGN FOR CARPET BEDDING.

FIG. 215. DESIGN FOR CARPET BEDDING.

Carpet Bedding. This mode of gardening, although not so generally employed as it was some few years ago, has many admirers, and small plots, geometrically arranged in multi-coloured beds on lawns, are frequently seen. In our large public parks, the system is largely adopted, and evidently proves very gratifying to the multitudes who visit these places; but probably no system is more unnatural or expensive, as such a large number of plants are necessary in order to produce a desirable effect. The illustrations (Figs. 214 and 215) represent two designs for Carpet Beds. The numbers placed in the various compartments indicate the way the different colours should be arranged, repeats being marked by the same cypher. A very varied and large selection of plants can be used for Carpet Bedding, some of which are quite hardy, such as Herniaria glabra and Veronica repens, two of the best dwarf green plants; Sempervivum californicum, Sedum lydium, S. glaucum, Antennaria tomentosa, &c. These may be planted early in the season, with Golden Feather, and are especially valuable, as they are generally employed to a great extent. Other plants, not quite so hardy, are Mentha Pulegium gibraltarica and Echeveria secunda glauca, both of which are extensively used; while the tenderest subjects are Alternantheras of various kinds, Coleus Verschaffeltii and Mesembryanthemum cordifolium variegatum. These latter should not be planted till the first or second week in June. As the plants are usually small, and require to be planted thickly, the work is best accomplished with the fingers, pressing the soil moderately firm. First of all, work out the design, and plant the leading lines; afterwards fill in the "panels."

FIG. 216. DESIGN FOR BEDDING.

Sub-Tropical Bedding. This term is applied to the arrangement of tropical plants in Beds or groups outside for the summer months, and if discriminately adopted a very attractive and unique display may be made, depending greatly upon position, and mainly upon the material at command. If a sheltered and partially shady situation is[166] enjoyed, a grand effect may be produced by the grouping of tree and other large ferns with palms, Cannas, Aralias, Dracænas, &c., avoiding, of course, formal arrangement, and yet, when finished, a symmetrical appearance should be produced. In more open positions, palms, Castor Oil Plants, Cannas, Humea elegans, Aralias, Phormiums, Wigandias, Nicotianas, &c., may be employed, the result being, if properly arranged, most gratifying. Sub-Tropical Bedding should not be done till the middle or end of June, and the Beds should be well dug and freely manured for those that are to be planted out.

FIG 217. DESIGN FOR BEDDING.

Fig. 216 represents a Border or long piece of ground, which may be either marked out permanently with Box edging, dwarf-growing silver or golden leaved plants, tiles, stones, or pebbles, and filled in with silver sand or bright-coloured stones or gravel; or the lines may be widened out into walks. The whole of the small circles not numbered are intended for specimen foliage and other plants, such as Fuchsias, Yuccas, Aloes, Cannas, Solanums, variegated or plain Reeds, Grasses, Maize (Zea), &c. No. 1, tall plants of Echeveria metallica, edged with E. glauca; 2, 2, yellow or orange Calceolaria; 3, 3, Mrs. Leavers Pelargonium; 4, 4, Triomphe de Stella ditto; 5, 5, purple or blue Verbena; 6, 6, white ditto. The narrow border round the side may then be filled in with Golden-feather Pyrethrum, blue Lobelia, or Alternanthera amabilis. This same plan may also be treated in quite a different manner, according to the taste of those adopting it, or the stock of plants at command.

FIG. 218. DESIGN FOR BEDDING OR CARPET BEDDING.

Fig. 217 illustrates a design admirably adapted for a rosery or small flower garden. Its only fault is the number of sharp angles at the corners of some of the Beds; but this can be counteracted by the predominance of curved lines. It is easily formed, and the effect is good if furnished in the following manner: The circle in the centre, 1, Centaurea ragusina compacta, edged with a double line of Coleus Verschaffeltii; the four figures 2, 2, 2, 2, scarlet Pelargoniums, such as Vesuvius, Bonfire, Triomphe de Stella, or others; 3, 3, Mrs. Pollock, golden-zoned Pelargoniums, edged with Alternanthera amœna; 4, 4, Lady Cullum, ditto, ditto, edged with ditto; 5, 5, Lobelia speciosa, Imperial Dwarf Ageratum, or Purple King Verbena; 6, 6, white Verbena or white Ivy-leaved Pelargonium.

FIG. 219. ARRANGEMENT OF NURSERY FOR ROSE TREES AND SHRUBS.

FIG. 220. ARRANGEMENT OF NURSERY FOR ROSE TREES AND SHRUBS.

The group of Beds illustrated in Fig. 218 is effective on grass or gravel. If on the latter, the lines should be defined with Box, Golden Thyme, Cerastium, or Santolinas. The design is pretty on level, but is still more effective on sloping ground; in the latter case, it should rise from the straight walk (dotted line). Thus each Bed may be seen to the best advantage, and the group may be extended to any length. The circular Beds should be planted with two distinct colours, such as good pink and scarlet Pelargoniums of similar habits of growth, placing[167] the colours in alternate Beds. The Beds, a, a, a, Flower of Spring, or another silver-leaved Pelargonium; b, b, b, Purple King Verbena, or Imperial Dwarf Ageratum; c, c, White Perfection Verbena, and silver-leaved or white-flowered Ivy-leaved Pelargonium; d, d, Alternanthera magnifica; e, e, Blue Lobelia. The long border, Alternanthera paronychioides, edged with Antennaria tomentosa; or Iresine Lindenii, edged with Pyrethrum, Golden Fleece or Crystal Palace Gem Pelargonium. The two sides may also be planted alike. The colours are reversed above to produce a greater variety and a more striking effect. This design is also well adapted for Carpet Bedding.

FIG. 221. BEDDING-OUT DESIGNS.

Nursery Bed. This is merely a reserve ground or nursery for a large stock of plants of various sorts, such as Roses, &c. One of the first requirements is an easy access to the individual plants, and with the least possible waste of space. This may be obtained by arranging the Beds in regular geometric figures, as shown in Figs. 219 and 220, and, by exercising a little care and taste, the whole can be so contrived as to present an ornamental appearance.

We are indebted to Messrs. Cannell and Sons for the diagrams of Bedding-out designs shown at Fig. 221, which may be made very effective:

Bed A. This Bed may be planted with the following: Summer-flowering: 1, Gain's Yellow Calceolaria or Ageratum Lady Jane; 2, Geranium Vesuvius or another scarlet; 3 and 4, Viola Blue-bell or Purple King Verbena; 5, edged with Gnaphalium lanatum, or Antennaria tomentosa, white foliaged plants. Summer Foliage: 1, Coleus Verschaffeltii; 2, Centaurea ragusina compacta; 3 and 4, Mrs. Pollock Geranium; 5, band of any of the Echeverias, or Kleinia repens.

Bed B. Plants mentioned for A will do for this.

Bed C. This is really intended for a Carpet Bed. 1, Alternanthera amabilis, with a narrow line of amœna for the edge; 2, Mentha, or Herniaria glabra; 3, band of Mesembryanthemum cordifolium variegatum. Flowering: 1, Any kind of Scarlet Geranium; 2, Golden-leaved ditto; 3, Blue Lobelia (edge). Spring: 1, White Arabis; 2, Myosotis dissitiflora; 3, Golden Feather.

Bed D. Summer: 1, Pink Geranium; 2, Iresine Lindenii; 3, Golden Feather. Carpet: 1, Alternanthera versicolor grandis; 2, Mesembryanthemum cordifolium variegatum; 3, Alternanthera magnifica, edged with Sempervivum montanum.

Bed E. 1, Scarlet Geranium; 2, Pink ditto; 3, Lobelia speciosa; or, 1, Alternanthera amœna; 2, Mesembryanthemum cordifolium variegatum; 3, Echeveria secunda glauca.

Bed F. 1, Dracæna, Chamæpeuce, or any other graceful foliage plant for the centre; 2 and 4, Alternanthera amabilis, the divided lines, 6, being filled with Mentha or Echeverias; 3 and 5, Alternanthera amœna; and the outer edge, 7, with Sempervivum californicum. This bed would look well if planted with any of the above-mentioned spring flowers. Spring: Bed might be raised to a mound, and lined out with hardy Sedums, or Sempervivums, placing a larger growing one in the centre; and 2, 3, 4, and 5 divisions may be filled with any spring-flowering dwarf-growing plants.

Bed G. 1, Small plant of Yucca; 2, Coleus Verschaffeltii; 3, Alyssum variegatum; 4, Lobelia pumila magnifica.

Bed H. 1, Golden Feather; Mesembryanthemum; 3, Mentha; 4, Alternanthera amabilis; or 1, Coleus Verschaffeltii; 2, Centaurea ragusina; 3, Calceolaria Golden Gem; 4, Ageratum Lady Jane.

BEDDING PLANTS. This term applies to many half-hardy subjects which are planted out in beds for summer display, such as Ageratums, Calceolarias, Geraniums, Heliotropes, Lobelias, Verbenas, &c., all of which will be treated under their respective headings. They are mostly soft-wooded plants and are easily cultivated with proper means, in spring and autumn.

BEDFORDIA (named in honour of a former Duke of Bedford). ORD. Compositæ. Greenhouse evergreen shrubs, allied to Cacalia. They thrive in a mixture of sand, peat, loam, and brick rubbish, in equal proportions. Propagated by cuttings, which should be dried a little before inserting them in rough, sandy soil.

> B. salicina (willow-like). fl.-heads yellow, axillary and solitary, or few together. April. l. alternate, lanceolate, linear, glossy above, covered with white tomentum underneath. h. 3ft. Victoria and Tasmania, 1820. SYN. Cacalia salicina. (B. R. 923.)

BEET (Beta, which see). The present varieties of Beetroot are the offspring of Beta vulgaris, a plant of biennial duration, and a native of the sea coasts of Southern Europe. It was cultivated in this country about 1656, but was probably long previously introduced by the ancient Romans. Beetroot is largely used as salad, more extensively on the Continent than with us, also pickled; medium sized, deeply coloured roots being the chief desideratum. Some varieties are largely grown for their highly-coloured foliage, being planted in bedding-out designs, and generally proving extremely effective.

FIG. 222. LONG YELLOW BEETROOT.

Cultivation: For obtaining the best results, an open situation should be chosen, free from the shade of trees. The ground should be light and sandy, and, if possible, that which has been previously manured for some other crop, French beans, for instance. Trench the soil to a depth of 2ft. in the autumn, and ridge it up for the winter. As soon as dry enough to allow of working in spring, dig over the whole bed with a steel digging fork, and break the soil tolerably fine. Sow any time from the last week in April to the end of May. Prepare the drills about a foot or 15in. apart, and from 1in. to 2in. deep. The seeds grow quicker if steeped in water previous to sowing, afterwards allowing them to get dry enough to separate from each other. Sow thinly, and fill in the drills with a rake. As soon as the plants are up, hoe between the rows, and keep free from weeds. In a fortnight or three weeks after this hoeing, if the weather has been favourable, the plants will be large enough for thinning. Thin out to about 9in. apart, and carefully fill up, in dull weather, any blanks that may occur. Transplanting is, however, not generally a very satisfactory method. Carefully lift the roots in autumn, before frost comes, and wring off the leaves about an inch from the crowns. Place the roots in a cool shed or house, and allow the soil on them to get quite dry, when they may be stored for winter use in dry sand, or soil, in a shed free from frost. It is preferable to keep the crowns free from soil, to prevent decay from the ends of the leaves left on them. If this be carefully done, the roots will keep till the next season's early crop is ready. In all processes connected with the growing, storing, or cooking of this vegetable, the greatest care must be taken to avoid bruising or otherwise injuring the roots, as deficiency of colour would be the result, especially in the case of the red-fleshed kinds, in some cases rendering them valueless for table use. Seed Saving: When lifting the crop in autumn, select as many of the best formed and coloured roots as required, and store them separately from the rest. In April, plant them in a spot by themselves, where there is no danger of impregnation from other varieties, and in due time good seed will ripen. If good foliaged varieties are required, the best should be selected when growing in the summer, and either be marked by some means, or have the inferior ones removed from them.

Sorts. These are somewhat numerous—almost every seedsman having a so-called "improved strain." Nutting's Dwarf Red, Chelsea, Pine Apple, Dell's Crimson and Red Castelnaudary, are the best of the crimson or red-fleshed kinds. The Egyptian Turnip-rooted is a distinct variety, with flesh of a good colour, and fine flavour; excellent for summer salads. Betterave de Bretagne is a Continental variety; the roots grow to a good size, with a distinct outer skin of a dark colour; flesh rich purple. The best of the yellow-fleshed kinds are Small Yellow and Long Yellow (see Fig. 222); but these are not grown nearly so much as the deep-coloured section; in fact, they are almost useless for garden purposes.

FIG. 223. WHITE LEAF BEETROOT.

Beetroot for Bedding Purposes: In this case, where the foliage is the main object, the seed may be sown in a reserve bed, and the plants transferred to their positions in the flower garden. If, however, a line is required in a ribbon or other border, the best plan is to sow there, and thin out the plants to equal distances. Dell's Crimson is one of the best varieties for this purpose, being very compact and of a good dark colour.

Varieties of the Leaf Beet (Beta Cicla), and Sea or Perennial Beet (Beta maritima), are sometimes, but very seldom, cultivated for the use of the leafstalks and leaves, the roots being hard and unfit for cooking purposes. They are at the best but substitutes for other vegetables—namely, the midrib for Sea-kale and the leaves[169] for Spinach. If desired, seeds may be sown in the way described for Beetroot, in April for using in autumn and winter, and in August for spring use, plants of the latter sowing being protected in severe weather. The best sorts are Red-stalked, Yellow-stalked, and White (see Fig. 223) or Silver Leaf.

BEET CARRION BEETLE (Silpha opaca). This destructive insect is frequently found in dead animals, but often its grub almost destroys the leaves of Beet and Mangold Wurzel crops. The grubs, which are black and shining, when full grown are from ⅓in. to ½in. long; the three segments next the head are rounded at the sides, but the other segments are sharp, and the tail segment has a sharp spine on each side. "When full-fed, the grubs bury themselves, and form cells at the depth of 3in. or 4in. below the surface of the earth, in which they turn to pupæ, and from these the Beetle has been seen to come up in about the space of a fortnight or three weeks" (Ormerod). The Beetles are flattish, and about five lines long, brown-black, with a tawny down; eyes large and oval; horns club-shaped; body somewhat oval; wing-cases very flat, turned up at the outer edge, each case having three sharp ridges running along it; tip of abdomen dull red. Any manures or methods of cultivation that would stimulate growth in the plants, so as to permit renovation of injuries, would be found useful. If farmyard manure were applied to the soil intended for Beet in the autumn instead of in spring, it would lessen the risk of attack to the Beets.

FIG. 224. COMMON GARDEN BEETLE.

FIG. 225. DEVIL'S COACH HORSE.

BEETLES (Coleoptera). Beetles form one of the most extensive orders of insects, there being upwards of 3000 known British species. They vary much in appearance, but a Beetle is readily recognised by its front wings, or elytra; these form a tough horny sheath or case, which lies over the real wings, and protects them when the insect is not flying. Sometimes, the elytra are very short (see Fig. 225); the mouth is fitted with jaws for cutting. The metamorphosis is complete, i.e., the larva or grub is very unlike either the quiescent pupa or the perfect insect. The period that elapses before Beetles arrive at their perfect state varies from a few weeks to two or three years, but is usually rather longer than in Butterflies or Bees. Various Beetles attack growing plants and roots. Thus, Otiorhynchus sulcatus and O. picipes attack Vines, Roses, and other plants, gnawing off the bark. Some species of Beetles attack Mushrooms, while others bore into the wood of old trees, or eat leaves (e.g. Turnip Fly), or burrow in the leaves, or form galls on roots (Cabbage-gall Weevil). Of some kinds, the beetles are hurtful; of others, the larvæ. Many kinds, however, are beneficial, such, for instance, as the common Ground Beetle (Carabus, Fig. 224), and the Devil's Coach Horse (Ocypus olens, Fig. 225). These live upon other insects and snails. One kind of Beetle—the Ladybird (see Figs. 226 and 227)—is very beneficial in a garden, as it preys upon the aphides, or plant lice. For instructions in dealing with the noxious kinds, see Asparagus Beetle, Bean Beetle, Beet Carrion Beetle, Click Beetle, Cockchafer, Lily Beetle, Rosechafer, and Turnip Fly.

FIG. 226. SEVEN-SPOTTED LADYBIRD. FIG. 227. GRUB OF LADYBIRD. (Enlarged).

BEET or MANGOLD FLY (Anthomyia betæ). The maggots of this fly do considerable damage by feeding on the pulp of the Beet or Mangold leaves. The eggs are small, white, and oval, and are laid in small patches beneath the leaves; the maggots are about ⅓in. long, legless, cylindrical, and yellowish-white. As it is of such recent appearance in this country, specifics for its eradication are by no means numerous; but, according to Miss Ormerod, "the best treatment appears to be to nip it in the bud, where such treatment is possible, by destroying the infested plants, but generally by all means of good cultivation, or by special applications of artificial manure, to ensure a hearty growth, which may run the plants on past the power of average attacks to weaken the leafage to a serious extent."

BEFARIA (named in honour of Bejar, a Spanish botanist). ORD. Ericareæ. SYN. Bejaria. An elegant genus of greenhouse evergreen shrubs, closely allied to Rhododendron. Flowers bracteate; corolla very deeply seven-cleft, spreading. Leaves racemose or corymbose, crowded, quite entire, coriaceous. They thrive in a compost of peat and loam. Propagated by cuttings, made of the young wood, and placed in sandy soil, in gentle heat.

> B. æstuans (glowing).* fl. purple; corymbs terminal, simple; peduncles, pedicels, rachi, calyces, and branchlets clothed with clammy glandular hairs. l. elliptic, rather glabrous above, but downy and glaucous beneath, while young clothed with rusty tomentum. Plant much branched; branchlets sub-verticillate. h. 10ft. to 15ft. Peru, 1846. SYN. Acunna oblonga. (G. C. 1848, 119.)

> B. cinnamomea (cinnamon-coloured). fl. purple; panicles close, terminal; peduncles woolly, hispid. l. slightly downy above, rusty tomentose beneath. Branches downy, hispid. h. 4ft. Peru, 1847.

> B. coarctata (close-headed). fl. purple; corymbs terminal, simple; peduncles, pedicels, rachi, and calyces clothed with rusty tomentum. l. oblong, glabrous, glaucous beneath. Shrub much branched. h. 4ft. to 5ft. Peru, 1847. (G. C. 1848, 175.)

> B. glauca (glaucous).* fl. flesh-coloured; racemes terminal and axillary; pedicels somewhat fastigiate. June. l. oblong, obtuse, glaucous beneath. Shrub much branched; branchlets angular. h. 3ft. to 6ft. South America, 1826.

Shrub much branched; branches purplish. h. 3ft. to 4ft. South America, 1847. (F. d. S. 3, 195.)

> B. racemosa (racemed). fl. purple, disposed in racemose terminal panicles. July. l. ovate-lanceolate, glabrous; branchlets smooth or hispid. h. 3ft. to 5ft. Georgia, 1810.

BEGONIA (named after M. Begon, a French patron of botany). ORD. Begoniaceæ. A large genus of succulent herbs or undershrubs (a few climbers), in many of which the stem is reduced to a tuberous rhizome, whilst some are distinctly tuberous. Flowers usually showy and large, white, rose, scarlet, or yellow, unisexual; perianth segments petaloid, four to five divisions, rarely two. Stamens numerous, filaments free or united at the base. Ovary inferior, styles two to four, free, sometimes connate, stigmas brandied or twisted. Fruit capsular, rarely succulent, often winged. Seeds numerous, minute. Leaves[170] alternate, more or less unequal-sided, entire, or lobed, or toothed. Flower-stalks axillary, cymose. Distribution: Species about 350, in all tropical moist countries, especially South America and India; not known in Australia. Cultivated species (exclusive of garden hybrids and varieties) about 150. A large number of genera, or what were considered as such are now merged in Begonia—viz., Barya, Baryandra, Casparya, Pritzelia, &c. The rich colours and beautiful form of the flowers of Begonias, their prettily-marked foliage, and free-growing, free-blooming nature, have long marked them out as favourite garden plants. Within the last twenty years a new race, characterised by a tuberous root-stock, annual herbaceous stem, and large handsome flowers, has been introduced from the Andes of South America, from which, by means of careful cross-fertilisation and selection, a large number of beautiful and almost hardy kinds have been raised. The size, substance, and rich colours of the flowers of the majority of the plants of this race of Begonias are witness to what may be done by skilful cultivation and careful cross-breeding among plants. In the same way the large-leaved, stemless section, of which B. Rex may be taken as the type and principal progenitor, have been improved both in the size and the coloration of their foliage, and countless forms are now in cultivation, both as garden plants and for the decoration of rooms, &c. The propagation of Begonias may be accomplished by means of seeds, which are freely produced by almost all the cultivated kinds, by cuttings, by division of the rhizomes, and—in the case of the large-leaved kinds—by leaf-cuttings. For the first of these methods it is necessary that the seeds should be well ripened before they are gathered, and kept dry until sown. Where it is desired to increase any particular kind of garden origin, seeds are useless, none of the hybrid or seedling forms perpetuating themselves through their seeds, although equally beautiful sorts may be raised from them. The characters of all true species are, however, reproduced in their seedlings. For the successful raising of Begonia seeds it is necessary to sow them on pans or pots of well-drained, light, sandy soil, which should be well watered before the seeds are sown. The seeds should not be covered with soil, or they will fail to germinate. Over the pans a pane of glass should be placed, and they should then be stood in warm house or a frame where a temperature of about 65deg. can be maintained, and shaded from sunshine. As soon as the plantlets are large enough to be safely manipulated, they should be pricked off into pans of light leaf-mould soil, in which they may remain until large enough to be placed singly in pots. Cuttings: These strike freely if planted in small pots, in sand and leaf mould, and placed on a bottom heat of 70deg. Where large quantities are required, a bed of cocoa nut-fibre in a stove or propagating frame may be used, and in this the cuttings may be planted and remain until well rooted. Leaf cuttings succeed best when laid on sand or cocoa-nut fibre, and shaded from bright sunlight. In preparing the leaves, old, well-matured ones should be selected, and incisions made with a sharp knife across the principal nerves on the underside. They should then be placed on the sand or fibre and held down by means of a few pieces of crock. Under this treatment, bulbils will form on the lower ends of the nerves of each section of the leaf, and these, when large enough, may be removed from the bed and potted. With the exception of B. Evansiana (discolor), an almost hardy species from North China, all the shrubby species require a warm or intermediate house for their cultivation, although during the summer months a frame or sheltered bed answers for most of them, provided they are removed into their warm winter quarters on the approach of cold weather. Some of the species, such as B. Dregei, B. semperflorens, B. nitida, B. fuchsioides, B. Lindleyana, B. Richardsiana, along with the hybrids Ascotensis, Knowsleyana, Weltoniensis, and Ingramii, are grown in pots out of doors all the summer, and under liberal treatment they form large handsome specimens, which are of great value as flowering plants for the conservatory in winter. The tuberous-rooted herbaceous kinds should be started in heat in February, and, when vigorous growth has commenced, be gradually hardened off, for use either as bedding plants or as pot specimens for flowering in the greenhouse. A mixture of loam and leaf mould with a little sand and rotten cow-dung is suitable for the cultivation of these plants in pots. Liberal supplies of water should be given during the growing season. As the growth decays, water should be withheld until finally the tubers may be shaken out of the soil and placed in dry sand or cocoa-nut fibre, in a house or shed where a temperature above freezing can be maintained. B. gracilis and its varieties, diversifolia and Martiana, are beautiful greenhouse plants, which thrive well if treated as advised for the other tuberous-rooted kinds, with the addition of a few more degrees of heat.

The Rex section requires a light rich soil, plenty of moisture, and a shaded position in a warm greenhouse. These kinds are often employed with good effect for clothing peat-covered walls in ferneries, or as an undergrowth in large tropical houses. Large specimens have been grown under the stage in a warm house, the shade and moisture of such a position being exactly what they best delight in.

B. socotrana, an interesting species from the island of Socotra, is somewhat singular in its requirements. The stem is herbaceous and annual, and about its base a cluster of bulbils are formed, from every one of which a plant will be developed the following year. The growing season for this species is from September to March, after which it goes to rest for the whole summer. A tropical temperature and all the light possible, are essential to the well-doing of this plant.

It is interesting to note the apparent impossibility to cross any of the shrubby Begonias with the distinctly tuberous-rooted species; and even the species of the shrubby section, whose stems are semi-tuberous, have hitherto refused to commingle with the South American tuberous kinds, of which B. Veitchii, B. rosæflora, and B. boliviensis may be said to be typical. The infusion of the blood of these large, handsome-flowered kinds into the tall, shrubby species, would almost certainly result in the production of a race of splendid winter-flowering greenhouse plants, and it is therefore in every way desirable that no pains should be spared to break through the obstacle to the union of the two races.

BEGONIACEÆ. An order comprising a large number of useful garden plants. The only genera are Begonia and Begoniella (which is not yet in cultivation). Flowers apetalous; perianth single; pistillate flowers having the perianth two to eight-cleft, staminate ones two to four-cleft; stamens numerous, collected into a head. Leaves alternate, stipulate. See Begonia.

BEJARIA. See Befaria.

BELLADONNA. See Atropa.

BELLADONNA LILY. See Amaryllis Belladonna.

BELLEVALIA (named in honour of P. R. Belleval, a French botanist). ORD. Liliaceæ. This genus is now usually placed under Hyacinthus. Hardy, bulbous-rooted plants, admirably adapted for spring bedding or forcing, and invaluable as cut flowers. Flowers small, whitish, or violet, tinged with green. Leaves few, radical, broadly linear. They are of extremely easy culture in ordinary garden soil. Propagated by offsets; also by seeds, which should be sown as soon as ripe.

> B. operculata (lid-covered). Synonymous with B. romana.

> B. romana (Roman).* Roman Hyacinth. fl. white, racemose; perianth campanulate; pedicels longer than the flowers. April. l. from 4in. to 5in. long. h. 6in. Italy, 1596. A most desirable plant, and the best of the genus for forcing purposes. SYNS. B. operculata and Hyacinthus romanus. (B. M. 939, under the name of Scilla romana.) See Hyacinthus.

> B. syriaca (Syrian).* fl. white; peduncles spreading, racemose. May. l. glaucous, 1ft. long, channelled, rather scarious on the margins. h. 1ft. Syria, 1840.

BELL-FLOWER. See Campanula.

FIG. 237. FRENCH BELL GLASS, OR CLOCHE. FIg. 238. ENGLISH BELL GLASS.

BELL GLASSES, or CLOCHES. These are used for the purpose of protecting or accelerating the growth of a plant or plants. The French Cloche (see Fig. 237) is largely employed for this purpose. Ordinary Bell Glasses (see Fig. 238) are exceedingly useful for propagating purposes, especially for hard-wooded plants; or for placing over subjects which require a very moist atmosphere, such as Filmy ferns, Cephalotus, &c.; or for covering half-hardy plants or rare alpines, and thus protecting them from excessive moisture. Large Bell Glasses, inverted, serve as miniature aquaria, and many small aquatics are easily grown in them.

BELLIDIASTRUM (from bellis, a daisy, and astrum, a star; flower-heads being star-like). ORD. Compositæ. A pretty dwarf, hardy, herbaceous perennial, allied to Aster. It thrives in a compost of loam, leaf soil, and peat. Increased by divisions in early spring, or directly after blooming.

> B. Michelii (Michel's).* fl.-heads white; scape one-headed, naked; involucre with equal leaves; pappus simple. June. l. in a rosette, shortly stalked, obovate, repand. h. 1ft. Austria, 1570.

BELLIS (from bellus, pretty, in reference to the flowers). Daisy. ORD. Compositæ. A genus of hardy herbaceous perennials, distinguished from allied genera in having conical receptacles and an absence of pappus. They grow well in all loamy soils. The garden varieties are increased by division after flowering, each crown making a separate plant. The soil must be pressed about them moderately firm. Seeds may also be sown in March, but the plants thus obtained are seldom of sufficient floricultural merit to perpetuate.

FIG. 239. BELLIS PERENNIS FLORE-PLENO.

FIG. 240. HEN AND CHICKENS DAISY (BELLIS PERENNIS PROLIFERA).

> B. perennis (perennial).* Common Daisy. fl.-heads white. June. l. numerous, lying flat on the ground, obovate, crenate, slightly hairy, tapering at the base. h. 3in. England. The varieties are very numerous, the double ones being particularly fine. See Fig. 239. The handsome variegated form, aucubæfolia, has its leaves richly stained and veined with yellow. There are both red and white-flowered forms of this variety. The Hen and Chickens Daisy is a proliferous form, rather more quaint than[180] pretty. See Fig. 240. Good garden kinds are B. p. conspicua, red; CROWN, pink; ELIZA, purple; RUBENS, red; SNOWFLAKE, white.

FIG. 241. BELLIS ROTUNDIFOLIA CŒRULESCENS.

> B. rotundifolia cœrulescens (round-leaved, bluish).* fl.-heads from ¾in. to 1¼in. in diameter, resembling those of the common Daisy, but with fewer, often broader, ray-flowers, which vary from white to pale blue. l. more or less hairy, with slender stalks, 1in. to 3in. long; blade ovate or sub-cordate, sinuate toothed, three-nerved. Morocco, 1872. A very beautiful perennial, requiring the shelter of a cold frame during severe winters. See Fig. 241. (B. M. 6015.)

BELLIUM (from bellis, a Daisy; the flowers resembling those of that plant). ORD. Compositæ. A genus of pretty little, free-flowering plants, differing from the common Daisy only in having a pappus of six to eight broad scales, torn at the apex, alternating with a like number of long scabrous bristles. They thrive best in a mixture of sandy loam and peat. Propagation is readily effected by means of seeds or divisions; the latter should be made in spring.

FIG. 242. BELLIUM BELLIDIOIDES.

> B. bellidioides (Daisy-like).* fl.-heads white, solitary. June to September. l. spathulate, radical. Stolons creeping. h. 4in. Italy, 1796. Annual. See Fig. 242.

> B. crassifolium (thick-leaved). fl.-heads whitish-yellow; scapes much exceeding the leaves, downy. June. l. sub-radical, thick, obovate, entire, attenuate at base, rather downy. Stems many, ascending. h. 6in. Sardinia, 1831. Hardy perennial. (S. B. F. G. 2, 278.)

> B. minutum (very small).* fl.-heads white and yellow, ½in. across, on slender stalks, longer than the foliage. June to September. l. narrow spathulate, attenuated at the base, slightly hairy. h. 3in. Levant, 1772. A rare little species, requiring a warm, well-drained position on the rockery.

BELLOWS. These were formerly employed for fumigating, but are now entirely superseded by the ordinary fumigators. The Sulphur Bellows is a very useful instrument for the uniform distribution of flowers of sulphur on vines and other subjects infested with mildew. In form it is very like those in common domestic use, but has a rose of small holes at the end of its nozzle, through which the sulphur is ejected.

BELL-PEPPER. See Capsicum grossum.

BELOPERONE (from belos, an arrow, and peronne, a band; in reference to the arrow-shaped connectivum). SYN. Dianthera. ORD. Acanthaceæ. Very pretty stove evergreen shrubs, allied to Justicia. Flowers blue or purple, borne in secund, axillary, or terminal spikes, frequently subtended with coloured bracts; corolla gaping, the upper lip concave, the lower trifid. They are easily cultivated in a compost of loam, leaf soil, peat, and sand. Propagated by young cuttings, taken in spring. Beloperones may also be treated like Justicias (which see), and will succeed admirably. There are a large number of species, but few of which have been introduced.

> B. oblongata (oblong). fl. rosy-purple; spikes axillary; anthers calcarate at base; bracts bracteolate. Summer. l. oblong-lanceolate, opposite. h. 3ft. Brazil, 1832. (B. H. 9, 9.)

> B. violacea (violet-coloured).* fl. violet. l. lanceolate, acuminate, entire. h. 3ft. New Grenada, 1859. (B. M. 5244.)

BENDING-DOWN the branches of fruit trees, by means of weights or string attached to pegs driven into the ground, is sometimes resorted to for the purpose of acquiring a particular shape, or fruitfulness; but authorities differ as to the usefulness of the plan for the latter purpose. Young trees that are inclined to grow strong in the middle may be more evenly balanced by adopting the plan of Bending the strong branches, and so diverting the sap to the weaker ones.

BENGAL QUINCE. See Ægle Marmelos.

BENJAMIN-TREE. See Ficus Benjamina.

BENT GRASS. See Agrostis.

BENTHAMIA (in honour of George Bentham, a distinguished English botanist). ORD. Cornaceæ. Hardy evergreen shrubs or low trees, now referred to the genus Cornus. The first-named species is rather tender in the neighbourhood of London, and can only be grown successfully against a wall, for which purpose it is very suitable. In Cornwall and other mild places, it attains a height of 20ft. in the open. Loudon thinks it might be rendered hardier by grafting it on Cornus sanguinea. Flowers disposed in heads, each head attended by an involucre, which consists of four petal-like parts, and resembles a corolla; calyx with a minute four-toothed limb; petals four, fleshy, wedge-shaped; stamens four; style one. Leaves opposite, exstipulate, sub-evergreen, entire. Fruit constituted of many pomes grown together. They thrive in rather moist, loamy soil, in a sheltered spot. Propagated by seeds, sown when ripe, in a cool-house; or by layering, in autumn.

> B. fragifera (Strawberry-flowered).* fl. large, white, sessile, densely aggregate, forming a round head. June to October. fr. large, about the size of that of the common Arbutus, reddish. l. lanceolate, acuminated at both ends, on short petioles, rather rough, with small, adpressed down. Branches spreading, smooth. h. 10ft. to 15ft. Nepaul, 1825. (G. C. xiv., 728.)

> B. japonica (Japanese). fl. yellowish-red. Spring. h. 8ft. Japan, 1847. (S. Z. F. J. 16.)

[181]

BERARDIA (named after M. Berard, a Professor of Chemistry at Montpelier). ORD. Compositæ. A genus containing a single species, confined to the high mountains of Western Europe. It makes a pretty rock plant, and grows best in thoroughly well-drained spots amongst rocky débris. Propagated by seeds, sown in spring.

> B. subacaulis (almost stemless). fl.-heads whitish, solitary, very large. l. rounded oval, nearly heart-shaped at base, cottony. h. 3in. or 4in. (A. F. P. 3, 38.)

BERBERIDACEÆ. An order of shrubs or herbaceous perennials. Flowers terminal or axillary, usually racemose; sepals three, four, or six in a double row; petals as many or double in number; stamens four to eight, opposite the petals. Fruit, a berry or capsule. Leaves alternate, compound. The order contributes a great number of handsome plants to our gardens. Well-known genera are Berberis, Epimedium, and Nandina.

BERBERIDOPSIS (from Berberis, the Barberry, and opsis, like; resembling the Barberry). ORD. Berberidaceæ. A handsome evergreen shrub, with climbing habit. Sepals and petals nine to fifteen; outer small, spreading; intermediate orbicular, concave; inner obovate-cuneate, erect, inserted upon the fleshy torus. Stamens eight to nine, free. With a slight winter protection, or planted at the foot of a south wall, it will prove quite hardy, being of easy culture in ordinary garden soil. It is an excellent plant for the cool greenhouse. Increased by seeds, which should be sown in spring; by layering, in autumn; or by young cuttings, in spring.

FIG. 243. FLOWERING BRANCHES OF BERBERIDOPSIS CORALLINA.

> B. corallina (coral-red).* fl. crimson, in terminal, drooping racemes, leafy at the base. l. about 3in. long, alternate, simple, petiolate, oblong-cordate, obtuse or acute, spiny-toothed. Chili, 1862. See Fig. 243. (B. M. 5343.)

BERBERIS (Berberys is the Arabic name of the fruit, signifying a shell; many authors believe this to be the original derivation of the word, because the leaves are hollow, like a shell). Barberry. ORD. Berberidaceæ. Including Mahonia. A genus of hardy erect or trailing shrubs. Flowers yellow or orange, racemose or fascicled; sepals and petals similar, in two series. Leaves simple or compound, alternate or fascicled from the non-development of the branches, often spinose, or reduced to spines. The common sorts thrive well in any ordinary garden soil, but the rarer kinds require a compost of loam, peat, and a little sand. Propagation may be effected by suckers or layers, put down in the autumn; by ripened cuttings, taken at the same time, and planted in sandy soil, in a cold frame; or by seeds, sown in the spring, or, preferably, in the autumn, when, if fresh from the pulp or berry, they will germinate in the open in the following spring. The last-named is the method generally adopted.

> B. Aquifolium (Holly-leaved).* fl. yellow; racemes nearly erect, much crowded. Spring. l., leaflets two to three pairs, with an odd one, the lower part distant from the petiole; ovate, approximate, cordate at the base, one-nerved, spiny-toothed. h. 3ft. to 6ft.

B. excelsa is a tall tree, having the young branches leafy at the apex. Leaves alternate, oblong, quite entire, rather coriaceous. From this Brazilian species are obtained the well-known Brazil or Para Nuts of commerce. The tree is of no value for decorative purposes.

BERTOLONIA (named after A. Bertoloni, an Italian botanist, author of "Rariorum Italiæ Plantarum Decades," &c.). ORD. Melastomaceæ. Elegant little creeping or dwarf-growing stove plants, chiefly cultivated for their exquisitely marked leaves. Flowers white or purple. Leaves stalked, ovate-cordate, five to eleven-nerved, crenulated; cymes corymbose, terminal. They thrive in a compost of equal parts peat, leaf mould, and sand, in a warm, close, and moist atmosphere, but are most successfully cultivated under a bell glass in the stove; in fact, the latter is the only plan of growing them where a constantly humid atmosphere cannot be otherwise obtained without such means. They are easily propagated by cuttings or seeds.

BESOM, or BROOM. Birch-brooms are best for garden purposes, and are generally used. The most suitable for paved yards are those made of the common Ling (Calluna vulgaris). Those made of bass fibres are frequently used on paths, for which they are very suitable, but their expensiveness prevents them being generally employed. Whatever material is used in its composition, a Besom will last much longer if soaked in water for some time before using.

BESSERA (in honour of Dr. Besser, Professor of Botany at Brody). ORD. Liliaceæ. An elegant little half-hardy, Squill-like, bulbous plant, from Mexico. Perianth bell-shaped, six-parted. Leaves narrow, linear. It requires a compost of loam, leaf soil, peat, and sand, with good drainage. If cultivated in pots, a plentiful supply of water must be given from the commencement of growth until ripening off. When at rest, however, it should be kept dry and cool, but secure from the effects of frost. If planted out, a well-drained sunny position must be chosen, such as close to the wall of a greenhouse with a southern aspect. Propagation may be effected by offsets.

> B. elegans (elegant).* fl. scarlet, or scarlet and white. July to September. l. 1ft. to 2ft. long, narrow, furrowed on the upper side. h. 2ft. Mexico, 1850. This is the only species. The colour of the flowers varies considerably, on which account other names have originated. (B. R. 25, 34.)

BETA (from bett, the Celtic word for red; in reference to the colour of the Beet). Beetroot. ORD. Chenopodiaceæ. Perianth single, half-inferior, five-cleft, persistent. Seed one, reniform, imbedded in the fleshy base of the calyx. B. Cicla is largely used as a decorative plant in sub-tropical and other styles of gardening. They require the same culture as the ordinary Beet. The other sorts, with dark blood-red leaves, are largely employed in flower gardens, and the roots utilised for culinary purposes. See also Beet.

FIG. 248. BETA HORTENSIS METALLICA, or VICTORIA BEET.

> B. Cicla (Sicilian). fl. greenish, disposed in threes. August. l. with very thick ribs. Roots scarcely any. h. 6ft. Portugal, 1570. The variety, B. c. variegata, usually known as the Chilian Beet, is a very handsome plant, having its leaves often more than a yard in length and over 1ft. in diameter, with a remarkably handsome variegation. The midribs are usually dark orange or scarlet. It is a most desirable and effective plant for sub-tropical gardening.

> B. hortensis metallica (metallic). Victoria Beet. An ornamental variety with glistening deep blood-red leaves. Useful for decorative purposes in summer, either as a single specimen or in a mass. Roots may also be used for cooking. See Fig. 248.

BETCKEA. See Plectritis.

BETEL, or BETLE. See Piper Betle.

BETONICA. This genus now forms a sub-division of Stachys (which see). Betony (Stachys Betonica) is a native herb formerly much used in medicine, but now almost entirely discarded.

BETONY. See Stachys Betonica.

BETULA. (according to some authorities, from Betu, its Celtic name; others give the derivation of the word as from batuo, to beat, the fasces of the Roman lictors, which were made of Birch rods, being used to drive back the people). Birch. ORD. Cupuliferæ. TRIBE Betuleæ. Ornamental, hardy (except where otherwise specified), deciduous trees or shrubs, allied to Alnus, having round, slender, often drooping branches, and the bark in most species in thin membranous layers. The flowers appear at the same time as the leaves. Male catkins cylindrical, lax, imbricated all round with ternate concave scales, the middle one largest, ovate; corolla none; filaments ten to twelve, shorter than the middle scale, to which they are attached. Female catkins similar, but more dense; scales horizontal, peltate, dilated outwards, three-lobed, three-flowered; corolla none. Nut oblong, deciduous, winged at each side. The Betulas are easily cultivated in any ordinary soil; but a light sandy loam suits them best. Most of the species are best increased by seeds, which ripen in September, and need to be dried, in order to prevent fermentation. They should be sown in March, in a sandy soil, the surface of which has been previously made perfectly level. They must be spread on the surface, and not covered with soil, but pressed down with the feet. When grown in quantities, beds 4ft. in width are preferred, with an alley of 1ft. between them. In early summer, if the weather be warm and dry, the beds should be shaded with branches. The young seedlings must be transplanted when a year old. The dwarfer kinds may be propagated by layering in the autumn. The numerous beautiful varieties are best increased by grafting or budding upon seedling stocks of the common kinds, the former being done in spring, and the latter in summer when the buds are ready. Those most useful as forest trees and for protection are quick-growing and very ornamental. The time of maturity of the Birch depends very much upon the soil and situation, but it seldom increases in size after it is thirty years old. The common species (B. alba) is one of the hardiest and most useful trees in cultivation, growing quickly, and withstanding exposure better than[186] many others; consequently it is invaluable for skirting and nursing more tender subjects, and is especially desirable for clothing mountainous and exposed districts. It is also very beautiful and picturesque. It is the commonest tree throughout Russia, from the Baltic to the Eastern Sea, frequently monopolising gigantic forests. In Italy, it forms excellent forests up to 6000ft. altitude, and in our own Highlands of Scotland it occurs up to a height of 2500ft. In Greenland, although much reduced in size, it holds its own as the only arboreal vegetation.

BIARUM (an ancient name of a plant). ORD. Aroideæ. A genus of small, hardy, tuberous-rooted perennials, much more curious than pretty, allied to Sauromatum. This genus, according to Dr. Masters, differs from Arum in its spathe being tubular at the base, with the limb spreading. The female flowers have a distinct style, and the fruit contains only one ovule. They will thrive in any light, rich, well-drained soil, and may otherwise be treated similar to the hardy Arums. There are several other species besides those named, but they are not yet in general cultivation.

BIENNIAL. A term applied to plants occupying two years in the development from seed to the maturation of seed: growing one year, flowering, fruiting, and dying the next. Seeds of Hardy Biennials are, as a rule, sown from June to August, to flower the succeeding season. Tender varieties are sown in a frame or cool house, and kept there all winter, being transferred from the frames or houses to the open border, in June. Wallflowers, Foxgloves, Canterbury Bells, and Sweet Williams, may be taken as fair types of Biennials, although they often assume more than a Biennial character on light sandy soils.

FIG. 250. BRANCH AND FLOWERS OF BIGNONIA MAGNIFICA.

BIGNONIA (so named by Tournefort, in compliment to the Abbé Bignon, librarian to Louis IV.). ORD. Bignoniaceæ. A large genus of usually scandent shrubs, furnished with tendrils; rarely erect trees or shrubs. Flowers axillary and terminal, usually panicled; corolla with a short tube, a campanulate throat, and a five-lobed, bilabiate limb. Leaves opposite, simple, conjugate, ternate, digitate or pinnatifid. These handsome plants are particularly suited for large houses, where, if well grown, they give great satisfaction. The primary point in their culture is to obtain free and, at the same time, sturdy growth, giving due attention to training, pruning, &c., or the plants soon exceed all limits. Like all free-growing plants, Bignonias thrive best planted out in the borders of the stove or greenhouse, or out of doors, as the case may be; but the space allowed should be limited, in order to restrict root production. They may either be trained to cover the back wall, or be planted in a border in front, and trained up the rafters, or on wires, arranged where most desirable. In summer, allow all the strongest shoots to grow, training them so as to have as much sunlight as possible—which is absolutely necessary to well[188] ripen the wood, and make it capable of producing flowers—without entirely shutting it out from the plants below. Soil: A compost of two part fibrous loam, one part peat, one of leaf mould, and a due proportion of sand, will be found most satisfactory. The loam and peat should be used in a rough state, unsifted, as this will keep the border open for some years, and thorough drainage should be effected. Propagation: Seed being rarely procurable, the most satisfactory method of propagation is by cuttings, made of good strong shoots, in early spring. Three joints are sufficient to make a cutting, if short-jointed; if long-jointed, two are sufficient. Place them in a well-drained pot of sandy soil, under a bell glass, in bottom heat. As these cuttings are young and fleshy, they are liable to damp off; hence it is necessary, for the first two or three weeks, to wipe the moisture from the glasses[189] every morning, and water sparingly. If well managed, they will root in about two months, and should then have the glasses left off every night for a week; they should then be transferred to small pots in the compost above described, passing it through a coarse sieve, to extract the stones and rough pieces of soil. After potting, the plants should be kept close for a short time, till they are able to bear full exposure to the light. In a year's time, they will be large enough to plant out in their permanent quarters. Bignonias may also be increased by layering.

BILLBERGIA (named after J. G. Billberg, a Swedish botanist). ORD. Bromeliaceæ. A genus of handsome stove plants. Flowers borne on light panicles; calyx three-parted; corolla of three convolute petals, scaly at the base; stamens inserted into the base of the perianth. Leaves harsh, rigid. These require much the same treatment as recommended for Æchmea. The most suitable soil is a mixture of peat, leaf soil, and loam in about equal parts, to which is added some sharp sand, to keep it open and porous. Free and perfect drainage is absolutely necessary for the successful culture of this class of plants, and a layer of moss should be placed over the crocks previous to filling the pots with soil. Although fond of heat, Billbergias will, when in flower, bear removal to a cooler house than a stove; and, if they are kept a little dry at the same time, the change will greatly prolong their blooming period. The stronger growing kinds thrive well in rich, well-drained loam and leaf mould. Propagation is effected by carefully taking off the suckers which form at the base, after the plants have done flowering; but, before doing this, they should be allowed to attain a good size. The suckers grow quickly when attached to the parent stem, from which they derive their strength, and feel the check less when severed; besides which, they become more mature, and are in better condition for rooting. The best method to adopt is as follows: Take the sucker in the hand and gently twist it off the stem; next trim the base by the removal of a few of the lower leaves, and then insert each sucker separately in a small pot, in sharp soil. A bottom heat of about 80deg. will greatly facilitate new root-growth; failing this, they will root freely in the temperature of a stove if placed in a shaded position for two or three weeks, after which they will bear increased light and sunshine during the later part of the day. See also Æchmea and Androlepis.

BINDWEED. See Convolvulus.

BIOPHYTUM (from bios, life, and phyton, a plant; the leaves of one species being sensitive to the touch). TRIBE Oxalideæ of order Geraniaceæ. A genus of pretty and interesting perennials, differing from Oxalis, in which genus it has been included, in the valves of the capsule being patent and separate to the base.

BIRDS. As a class, Birds are very much more useful than hurtful in gardens. Owls are of great use in catching mice, and Night-jars in catching night-flying insects. Rooks are very useful in lessening the numbers of wire-worms, and of hurtful insects in general; but, if very numerous, they may be driven to eat potatoes and other vegetable food, and may then do harm. The same may be said of Starlings. Blackbirds and Thrushes feed much on snails and worms, but they also feed on the ripe fruits in gardens. As a rule, slender-billed birds feed almost wholly on insects or other animals, and are to be encouraged in gardens at all seasons. Among these may be enumerated the Tree-creeper, Wryneck, Warblers, and Wrens of various kinds, Chats, Hedge-sparrow, Larks, Redstart, Robin, Titmice, and Wagtails. Swifts, Swallows, and Martins, are also great destroyers of insects. The Finches feed, in part, on insects, but also eat large quantities of seeds, and often do considerable damage among plants grown for seed, e.g., Cabbages, and in the seed-beds. Sparrows are about the most troublesome, though they are often assisted by Buntings, Chaffinches, Linnets, and others. When seed-beds or fruits have to be protected, this may be done by nets; or, more simply, by threads tied to sticks a few inches above the surface of the ground, or in front of the trees.

BISCUTELLA (from bis, double, and scutella, a saucer; in allusion to the form of the silicles). Buckler Mustard. ORD. Cruciferæ. Perennial or annual herbaceous plants, usually hispid, but sometimes downy or smoothish. Flowers yellow, scentless; pedicels filiform, bractless. Leaves oblong, entire, toothed or pinnatifid, somewhat radical or cauline. Stems round, erect, usually corymbosely branched at the top by racemes, which, when in flower, are short, but elongated at the time of fruiting. All the species produce seeds freely. The annuals should be sown in the open borders. Some of the perennial kinds are well adapted for ornamenting rockwork, in a dry, sunny situation. Of the annuals, columnæ, lyrata, maritima, and obovata, are best. Of the perennials, coronopifolia, lævigata, and sempervirens are the most desirable, but none are worth cultivation outside botanical collections.

BISERIAL, or BISERIATE. Arranged in two parallel rows.

BIXA (its South American name). Arnatto. ORD. Bixineæ. Stove evergreen trees, with dichotomous panicles of large reddish flowers, broad cordate leaves, and prickly capsules. A compost of loam and peat is well adapted to their culture. Propagated by seed, sown when ripe in bottom heat; or by cuttings, which root freely in sand, under a hand glass, in heat; the latter is the better method. If grown from seed, the trees attain a large size before they flower; whereas cuttings, taken from a flowering plant and struck, may be brought to flower when small plants.

> B. Orellana (Orellana). fl. pale peach-coloured; corymbs terminal, panicled; peduncles two, three, and four-flowered. May to August. l. cordate, ovate, acuminated, entire or angular, smooth on both surfaces. The drug called Arnatto is prepared from the red pulp which covers the seed of this species. It is used in the preparation of chocolate, and by farmers for colouring cheese, and also as an orange or yellow dye for silks. h. 30ft. West Indian Islands, 1690. See Fig. 253. (B. M. 1456.)

BIXINEÆ. An order of smoothish tropical trees or shrubs, not remarkable for any particular beauty. Flowers with or without petals, when present five and sepal-like; stamens indefinite in number, inserted in the receptacle or at the bottom of the calyx; peduncle axillary or terminal, bracteate, one or many-flowered, usually forming terminal panicles. Fruit fleshy or dry. Leaves alternate, simple, entire, or slightly lobed, generally full of pellucid dots. The genera best known are Azara, Bixa, and Flacourtia.

BLACK BRYONY. See Tamus communis.

BLACK BULLACE. See Prunus insititia.

BLACKBURNIA. See Xanthoxylum.

BLACK FLY or BEAN FLY (Aphis rumicis), also called Collier and Black Dolphin. This Fly (see Fig. 254) is found on many herbaceous plants. It is very injurious to Beans; hence, immediate means of destruction must be employed directly the insect appears. Its extermination is an extremely difficult matter; but the following remedies are very effectual:

Tobacco Water. This, made and applied as recommended for Aphides (which see) is a good remedy; but it is rendered more certain by the employment of soapsuds, instead of clear water, in its manufacture.

FIG. 254. THE BEAN FLY. a, Female, magnified; b, Male, natural size, and magnified.

Paris Green (Arseniate of Copper). Owing to its poisonous nature, this should not be used where there is fruit on the trees or vegetables under them; but there is no better destroyer of hard-dying insects. Its application is very simple. Mix 1lb. of the green with 30gals. of water, and well wet the infested parts of the trees, using a fine-rosed watercan or garden engine for the purpose. The operator's hands should be free from sores and scratches, or dangerous ulcerations may ensue.

Gas Liquor. If this can be obtained from a gas-house, it should be diluted with twice its bulk of water, and applied in the same manner as Paris Green, being washed off with clean water in a few hours. If the process be repeated on two or three consecutive nights, it will be found certain in its effects; moreover, it is not very poisonous. The finger or thumb, or the Aphis brush, applied early, will often exterminate these obnoxious insects at once. The first of the methods above described is perhaps the most accessible and the safest to use. Poisonous insecticides are[193] more or less dangerous, especially in the hands of the inexperienced. Black Fly is, however, one of the most difficult insects to eradicate, especially if allowed to multiply. A syringing of clean water should follow either of the above applications. See also Aphides.

BLÆRIA (named after Patrick Blair, M.D., F.R.S., who practised medicine at Boston, in Lincolnshire, and was author of "Miscellaneous Observations," 1718; "Botanic Essays," 1820, &c.). ORD. Ericaceæ. Pretty little greenhouse evergreen shrubs, natives of Southern and Tropical Africa. Flowers terminal, glomerate; corolla short-tubular, with a four-cleft limb, very freely branched. Leaves verticillate, with revolute margins. For culture, see Erica.

> B. articulata (jointed).* fl. reddish; heads drooping. May. l. four in a whorl, ovate or linear, glabrous, and shining; bracts solitary. h. 1ft. 1795.

> B. ericoides (Heath-like). fl. purplish-red. August. l. four in a whorl, oblong, obtuse, ringed; bracts three, length of the calyx. h. 2ft. 1774. SYN. Erica orbicularis. (L. B. C. 153.)

> B. purpurea (purple). fl. purple; heads drooping. June. l. four in a whorl, ovate, sub-ciliated. Stem flexuous, erect. h. 2ft. 1791.

BLAKEA (named after Martin Blake, of Antigua, a great promoter of useful knowledge). ORD. Melastomaceæ. Handsome stove evergreen shrubs or trees. Flowers red, large, showy; peduncles axillary, terete, one-flowered, naked, opposite or solitary, shorter than the leaves, usually with brown tomentum. Leaves petiolate, three to five-nerved, coriaceous, glabrous above and shining, but usually densely clothed with rusty tomentum beneath. They thrive well in peat, or a mixture of loam and peat, and require to be liberally supplied with water, particularly in spring and summer. Cuttings root freely if taken from shoots that are quite ripe (otherwise they are apt to rot), planted in a pot of sand, and plunged in a moist heat, under a hand glass.

> B. quinquenervia (five-nerved). fl. flesh-coloured, large, with white disks; peduncles twin, shorter than the petioles. June. l. elliptic, acuminated, naked, and shining on both surfaces, five-nerved. h. 10ft. to 16ft. Guiana, 1820. (A. G. 210.)

> B. trinervia (three-nerved). fl. rose colour, large; peduncles solitary, longer than the petioles. June. l. oval-oblong, three-nerved, glabrous and shining on both surfaces in the adult state, and when young serrulated; petioles and branchlets clothed with rusty tomentum. Roots issuing from the branches and stems. h. 4ft. to 8ft. Jamaica, 1789. (B. M. 451.)

BLANCHING. This process is effected for the purpose of obtaining crispness, and for converting what would, under ordinary circumstances, be a dangerous plant—in the case of Celery especially so—into a highly popular delicacy. Blanching can only be accomplished by entirely excluding the light from the plants, thus depriving the colouring matters of their power to decompose water and carbonic acid gas. It is also termed Etiolation.

BLANDFORDIA (named after George, Marquis of Blandford). ORD. Liliaceæ. A very beautiful genus of greenhouse bulbous plants, natives of Australia. Flowers solitary, on recurved pedicels; perianth funnel-shaped, six-cleft; stamens six. Leaves linear, elongate, striate; radical ones dilated, and somewhat sheathing at the base; others shorter and more distant, appearing on the flower-stem. The best soil in which to grow them is loam and peat in equal proportions, with a little rough silver sand added. They should be repotted moderately firm in the autumn, allowing good drainage, and should then be placed under the greenhouse stage, or in any other position where they will be free from water drippings. Water must only be given when dry, until they commence to grow, when it may be gradually increased, and they may be introduced into a higher temperature, if necessary, there to remain till after flowering. When the foliage is ripened off, they may be stored away until the time for repotting. Propagated by seeds and offsets, or by division of the old plants, which must be done when repotting.

> B. aurea (golden).* fl. 1½in. to 2in. long; scape bearing an umbellate cluster of three to five pure golden-yellow drooping bell-shaped flowers. Summer. l. narrow, linear, keeled or channelled, from the base of which the flower-scape arises. h. 1ft. to 2ft. New South Wales, 1870. (B. M. 5809.)

> B. Cunninghamii (Cunningham's).* fl. rich coppery red, the upper part yellow; about 2in. long, bell-shaped, pendulous; from twelve to twenty, terminating in a stout scape 3ft. high. June. l. linear, slightly keeled at the back, about ⅓in. broad. New South Wales. This magnificent species should have a little charcoal mixed with the soil already mentioned. (B. M. 5734.)

> B. C. hybrida (hybrid). fl. red, margined with clear yellow, bell-shaped, in a dense drooping umbel.

> B. flammea (fiery).* fl. dullish yellow, in dense umbel-like clusters; bracts ovate-lanceolate, stiff; perianth inversely conical. June. l. linear, bluntly keeled. h. 2ft. Australia, 1849.

> B. f. elegans (elegant).* fl. crimson, tipped with yellow, large, funnel-shaped. Summer. l. long, linear-ensiform. This very handsome form is often taken for the type.

> B. f. princeps (magnificent).* fl. rich orange-red externally, and bright yellow within, about 3in. long, tubular, borne on a scape about 1ft. high, slightly pendulous, and arranged near the summit. Summer. l. stiff, sub-erect, long, bright green, disposed in a distichous manner. This is a very splendid greenhouse plant, and should be in every collection. Australia, 1873. SYN. B. princeps. See Fig. 255. (B. M. 6209.)

> B. grandiflora (large-flowered).* fl. crimson, very large; bracts as long as the pedicels, the inner much the shortest. July. h. 2ft. New South Wales, 1812. (B. R. 924.)

> B. intermedia (intermediate). fl. yellow, pendulous, funnel-shaped, in sixteen to twenty-flowered racemes; bracts leaf-formed. September. l. channelled, acutely keeled, scabrous on the margins. h. 1½ft. Australia.

> B. marginata (margined). fl. orange-red, conical, in long pendulous racemes; bracts narrow, foliaceous, about equalling in length the pedicels. July. l. stiff, sub-erect, with scabrous margins. h. 2ft. Tasmania, 1842. (B. R. 31, 18.)

> B. nobilis (noble).* fl. orange with yellow margins, on long pedicels, drooping, disposed in a terminal raceme; bracts twice as short as the pedicels. July. l. very narrow. h. 2ft. New South Wales, 1803. (B. M. 2003.)

> B. princeps (magnificent). Synonymous with B. flammea princeps.

> B. L. trifoliatum (three-leaved). fronds furnished with one or two pairs of small oblong-obtuse lateral pinnæ at the base of the large terminal one. Stove variety. (H. S. F. 3, 94.)

> B. longifolium (long-leaved).* rhiz. slender, creeping. sti. firm, erect, nearly naked, 6in. to 12in. long. fronds 6in. to 9in. long, with a terminal pinna, and three to six lateral ones on each side, which are 3in. to 5in. long, and ½in. broad, narrowed gradually towards the point. sori in broad lines close to the midrib; texture coriaceous. Tropical America, 1820. B. l. fraxineum is a variety found in gardens under the name of B. fraxiniifolium, with a habit more close than the type; pinnæ six to eight on a side, sometimes 1in. broad.

West Indies, southwards to Chili and South Brazil, 1823. A very handsome stove or greenhouse fern.

> B. o. multifidum (much-cut).* A pretty variety, said to have been introduced from Dominica; the apices of the pinnæ are copiously crested and tasselled, rendering it very desirable. Stove variety.

> B. orientale (oriental).* cau. stout, erect, clothed at the crown with dark brown scales. sti. 4in. to 8in. long, strong, erect, scaly below. fronds 1ft. to 3ft. long, 6in. to 12in. broad, ovate, with very numerous nearly contiguous pinnæ on each side, which are 4in. to 8in. long, and about ¾in. broad, narrowed to a long point.

Tropical America, 1829. Widely distributed. Stove or greenhouse species. SYN. B. polypodioides, under which name it is usually found in gardens.

BLECHUM (a Greek name for an unknown plant, supposed to resemble Marjoram). ORD. Acanthaceæ. Stove herbaceous perennials. For culture, &c., see Justicia.

> B. Brownei (Browne's). fl. white, in a dense bracteated spike, which is four-cornered; bracts ovate, downy. Summer. l. ovate elliptical, somewhat toothed. h. 2ft. West Indies, 1780. The other species introduced are: angustifolium, blue; braziliense, blue; and laxiflorum, white.

BLEPHARIS (from blepharis, the eyelash; in reference to the fringed bracts of the calyx). ORD. Acanthaceæ. Dwarf shrubs or herbs, often spiny and woody, allied to Acanthus. Flowers in bracteate spikes; calyx cruciately four-parted, bracteate; upper segment entire, three-nerved; lower, two-nerved; corolla-tube very short; lip five-lobed, three lobes often much larger than the others; stamens four, sub-didynamous. For culture, &c., see Acanthus.

> B. procumbens (trailing).* fl. blue. July. l. linear lanceolate, spiny. h. 1ft. Cape of Good Hope, 1825. Greenhouse evergreen trailer.

BLEPHILIA (from blepharis, the eyelash; in allusion to the ciliated bracts). ORD. Labiatæ. Ornamental hardy perennials, closely allied to Monarda, but differing from it in the calyx tube having thirteen instead of fifteen nerves, and being naked in the throat, while the corollas are much smaller and more dilated. They are of easy culture in ordinary soil. Increased readily by dividing the roots in early spring.

> B. ciliata (ciliated). fl. blue; whorls all distinct; bracts ciliated, reddish at top. July. l. almost sessile, ovate-oblong, narrowed at the base, canescent beneath. h. 1ft. to 2ft. North America, 1798.

> B. hirsuta (hairy). fl. purple or blue; whorls more numerous than in the preceding; upper ones approximate. July. l. petiolate, ovate, roundly cordate at the base, hairy on both surfaces. h. 1ft. to 2ft. Virginia, 1798. Habit more branched and loose than in B. ciliata.

BLESSED THISTLE. See Cnicus benedictus, properly Carbenia benedicta.

BLETIA (in honour of Don Louis Blet, a Spanish botanist). ORD. Orchideæ. A large genus of, for the most part, stove terrestrial orchids. Flowers purple or whitish, in terminal racemes. Leaves narrow, grass-like. Pseudo-bulbs round, flattened. The flowers are freely produced when the plants are thoroughly established, and are valuable for bouquets, as well for their pleasing colour as for the time they last in perfection. Bletias thrive best in a compost of loam and leaf mould. About 2in. of crocks, covered with a layer of moss, should be placed[196] in the bottom of the pot, which should be filled to within 1in. of the top with soil. The bulbs should then be inserted, and just covered. A good supply of water during the growing season is necessary, and only a moderate amount of heat. After growth has ceased, a period of rest is required, during which time very little water should be given. Propagation is effected by divisions, which should be made after the plants have finished flowering, or previous to their starting into growth.

> B. campanulata (bell-shaped). fl. deep purple, with a white centre, lasting a considerable time in perfection. Mexico.

> B. florida (florid).* fl. pale rose-coloured; lip not spurred. July and August. h. 2ft. West Indies, 1786. A very pretty species. (B. R. 1401.)

> B. gracilis (slender). fl. pale greenish-white; sepals and petals nearly equal, lanceolate, acuminate; lip red and yellow; scape simple. l. oblong, lanceolate, plicate. h. 1½in. Mexico, 1830. (B. R. 1681.)

> B. hyacinthina (Hyacinth-like).* fl. purple, racemose; lip not spurred, beardless; scape about as long as the leaves. March to June. l. lanceolate. h. 1ft. China, 1802. This pretty species has proved to be quite hardy. (Garden, Nov., 1879.)

> B. patula (spreading-flowered). fl. purple, spreading; scape tall, branched. March. l. lanceolate. h. 2ft. Hayti, 1830. (B. M., 3518.)

> B. Shepherdii (Shepherd's).* fl. on branching spikes, purple, marked down the centre of the lip with yellow. Winter. l. long, lanceolate, dark green. Jamaica, 1825. (B. M. 3319.)

> B. Sherrattiana (Sherratt's).* fl. about a dozen on a spike, rich rosy purple; petals very broad, twice the breadth of the sepals; lip deep purple in front, marked with white and yellow down the centre. l. three to four-plicate. Pseudo-bulbs depressed. New Grenada, 1867. (B. M. 5646.)

> B. verecunda (modest). fl. purple; lip not spurred. January. h. 3ft. West Indies, Mexico, &c., 1733. (B. M. 930.)

BLIGHIA SAPIDA. The Akee Tree. This is now included under the genus Cupania (which see).

BLIGHT, or BLAST. Applied to various diseases of plants which are caused or accelerated either by the presence of parasitic fungi or insects, or by atmospheric influence. Blight generally proves fatal to the whole or part of the subject attacked.

BLIND. A term applied to plants which fail to produce central buds. The defect is frequently noticeable in the Cabbage, and other plants of the Brassica tribe; and is, perhaps, mainly due to the attacks of insects in a very early stage. Great care should therefore be exercised in keeping the seed beds clear of insect pests, by the application of ashes, lime, and soot, or spent hops.

BLOOD FLOWER. See Hæmanthus.

BLOODROOT. See Sanguinaria canadensis.

BLOOM. A fine powder-like substance found on Grapes, Cucumbers, Plums, &c., and varying in colour in the different subjects. It should be carefully protected, as it improves the appearance of the fruit. The term is also generally used—although incorrectly—as the plural of blossom.

BLOSSOM. The flower of a plant, or the essential organs of reproduction, with their appendages.

BLUE-BELLS. See Campanula rotundifolia and Scilla nutans.

BLUE-BOTTLE. See Centaurea Cyanus.

BLUE GUM TREE. See Eucalyptus globulus.

BLUETS. The French name for Centaurea Cyanus. See also Houstonia cœrulea and Vaccinium angustifolium.

BLUMENBACHIA (in honour of John Frederick Blumenbach, M.D., Professor of Medicine at Göttingen, and distinguished as a comparative anatomist). ORD. Loasaceæ. Elegant branched, climbing or trailing, annual, biennial, or perennial herbs, generally covered with stinging hairs, which are very objectionable. Flowers axillary, solitary, bracteate, very pretty and interesting. Leaves opposite, lobed. They are of easy culture in ordinary garden soil. Propagated by seeds, which should be sown in pots, in spring, and placed in a gentle heat, where they will germinate in about a fortnight. When the seedlings are large enough, and after having been previously hardened off, they may be planted out in their blooming quarters, or potted on and trained to a trellis.

FIG. 257. BLUMENBACHIA CHUQUITENSIS.

> B. chuquitensis (Chuquitan).* fl. solitary, axillary, with five to ten boat-shaped red petals, which are yellow within. September. l. oblong-lanceolate, pinnate; segments pinnatifidly lobed. Peru, 1863. Half-hardy climbing perennial. See Fig. 257. (B. M. 6143.)

> B. contorta (twisted).* fl. orange-red, with cup-shaped green scales within. July. l. oblong-ovate, pinnatifid; lobes incisely toothed. Peru. Greenhouse climber, but may be grown against a wall, out of doors, during the summer. (B. M. 6134.)

FIG. 258. FLOWER OF BLUMENBACHIA CORONATA.

> B. coronata (crowned).* fl. of pure glossy whiteness, quadrangular, crown-shaped, 2in. in diameter each way. June. l. narrow, bipinnatifid, cut into small segments. h. 1½ft. Chili, 1872. This is an elegant dwarf, tufted, erect biennial, with the pure white blooms imbedded in the metallic lustrous foliage. SYN. Caiophora coronata. See Fig. 258.

> B. insignis (remarkable).* fl. with whitish petals and reddish-yellow scales, axillary, on long peduncles, about 1in. in diameter.[197] July. l., lower ones five to seven-lobed; upper ones deeply bipinnatifid. h. 1ft. Chili, 1826. Hardy annual trailer. SYN. Loasa palmata. (B. M. 2865.)

BOBARTIA (named after Jacob Bobart, Professor of Botany at Oxford in the seventeenth century). ORD. Irideæ. A small genus of greenhouse or hardy bulbous plants, closely allied to Sisyrinchium. The species in cultivation are very pretty hardy plants, but require protection from severe frosts and excessive rains. They thrive best in a warm, light soil, and make pretty plants for rockwork. Propagated by separating the offsets during autumn. This genus has been much misunderstood. Among the plants which have been referred to it are some which now find places in the genera Aristea, Sisyrinchium, Homeria, Marica, Moræa, &c., &c.

> B. aurantiaca. See Homeria aurantiaca.

> B. gladiata (sword-shaped). fl. yellow, thinly sprinkled with purple dots near the centre, handsome, nearly 2in. across. l. linear, ensiform, narrow, slightly glaucous, 1ft. or more in length. 1817. SYN. Marica gladiata. (B. R. 229.)

> B. spathacea (rush-like). l. rush-like, several feet in length; flower-stem as long as leaves, bearing near extremity a cluster of pale yellow flowers, with narrow segments. Each flower lasts but one day; as a good many, however, are developed in each spathe, there is a succession which lasts some time. 1832. SYN. Xyris altissima. (L. B. C. 1900.)

FIG. 259. BOCCONIA CORDATA, showing Habit and Flower.

BOCCONIA (named after Paolo Bocconi, M.D., a Sicilian botanist, author of the "Museum des Plantes," and "Histoire Naturelle de l'Ile de Corse," &c.). ORD. Papaveraceæ. Two of the species are greenhouse or half-hardy shrubs. Flowers inconspicuous, in terminal panicles, with the branches and branchlets each furnished with one bract. Leaves stalked, glaucous, large, lobed. This genus does not well agree with the rest of Papaveraceæ, from its having one-seeded capsules and apetalous flowers. B. cordata is a handsome, hardy, herbaceous plant, with a stately habit and finely-cut foliage, and, where bold subjects are desired, few will be found superior to it. As an isolated specimen on the lawn, or by frequented walks, where it will not be too closely surrounded by tall plants, it may be grown with marked effect. It also forms a good subject for pot culture, and is largely used for sub-tropical bedding. The soil most suitable for its culture is a good fat loam, of considerable depth. Propagated by cuttings, taken from the axils of the larger leaves, during early summer; or by young suckers, taken from established plants, during summer, as they will then flower the following season. If the former method is employed, the cuttings should be pushed on, so that there are plenty of roots before the winter sets in. The other two species require greenhouse culture; but both are eminently suited for sub-tropical gardening, in any light rich soil, or well-drained and airy situation. They are best propagated by seeds, sown in a hotbed in spring, the seedlings being placed out from June to September.

> B. cordata (cordate).* fl. buff-coloured, very numerous, borne in very large terminal panicles; individually they are not showy, but the fully grown inflorescence has a very distinct and pleasing appearance. Summer. l. large, reflexed, deeply-veined, roundish-cordate; margins lobed or sinuated. Stems growing rather close together, thickly set with leaves. h. 5ft. to 8ft. China, 1795, and 1866. Mr. Robinson recommends its being grown in the angle of two walls which shelter it from the north and east. It runs quickly at the roots, and the suckers may be cut off to the benefit of the parent plant; each sucker will form a strong plant in a year's time. SYNS. B. japonica and Macleaya yedoënsis. See Fig. 259. (B. M. 1905.)

> B. frutescens (shrubby).* fl. greenish. October. l. large, sea-green, oval-oblong, cuneated at the base, pinnatifid. h. 3ft. to 6ft. Mexico, 1739. (L. B. C. 83.)

> B. integrifolia (entire-leaved). fl. greenish; panicle crowded. l. flat, oblong, tapering towards each end, entire, or scarcely crenated. h. 9ft. Peru, 1822.

> B. japonica (Japanese). Synonymous with B. cordata.

BŒBERA (named after Bœber, a Russian botanist). ORD. Compositæ. A genus of evergreen greenhouse shrubs, now generally referred to Dysodia. They are of easy culture, thriving in ordinary garden soil.

BOILERS. These are very important articles in all gardens where there are glass houses, and the best should always be selected. They are made in cast and wrought iron, both of which have their special advantages and disadvantages. The former are less liable to burn through when encrusted with any deposit from the water, but will crack with sudden changes of temperature, by reason of the granular form of the metal not allowing gradual contraction; the latter may burn through where there is any deposit of mud or other matter, but they will not crack, and will stand a greater pressure than those made of cast metal. It is, however, the better plan to use Boilers of wrought iron, as, with careful usage, they are less liable to break down in hard frosts than are the others. As the value of the plants, as well as that[198] of the Boiler, has to be considered, should such a contingency occur, it is certainly advisable to reduce all risks to a minimum; and as the average life of a Boiler is from ten to fifteen years, a slightly larger first cost is not of very serious moment. The forms of Boilers are very diverse, and, in some of the patented forms, complicated. But, whatever the shape, the following points are essential: A clear and unrestricted waterway of not less than 2in. in thickness; the greatest exposure of surface to the direct action of the fire; a sufficient fire space; and a fire-bar area calculated to supply enough fresh air to the fire to support thorough combustion. The forms generally used for horticultural work are the following, or some modifications of them; and, however grand the name, their chief value consists in the attested heating capacity at a given cost: The Saddle Boiler, which is made of various sizes, with or without check ends, cross tubes, and other devices for increasing the heating surface, and also of a tubular form; the Upright Cylinder (a vertical section of which is shown in Fig. 260); the Upright Tubular Cylinder; the Horizontal Tubular; and the Cornish or Horizontal Cylinder. Combinations of the various forms, and complicated patterns of different kinds, are made for particular purposes; but in no case should large Boilers be used, unless they are recommended, by one competent to judge, as suitable for the purpose they are needed to fulfil. In every case, it is necessary that the Boiler should be fixed in a proper manner. It is also good policy to have Boilers about 30, or even 50 per cent., more powerful than is actually required, when they are new, as, from various causes, their heating power falls off in a year or two in many places; and, under ordinary work, it is not desirable to stimulate the action in order to command sufficient heat. There is no doubt that, for general purposes, some modification of the Saddle or Cylinder Boiler is by far the best, all things duly considered; but it is impossible to give any practical advice without a thorough knowledge of the requirements of any particular place. Gas Boilers are also useful for small places. These are made in many forms, and are, as a rule, in the shape of a cylinder, with a coned inside, against which the flames play. Some Gas Boilers have also a superheater attached; this exhausts the heat from the air which has passed through the Boiler. Another good form is made of horizontal tubes, which contain the water, the flames playing over and amongst them. An atmospheric burner of approved construction should be used where gas is the heating power. A sufficient supply of gas should be assured by using supply pipes of a good size. Care should be taken to keep these pipes free from water, and protected from frost by silicate cotton lagging, or some other good non-conductor. Except for very small places, however, gas apparatus is almost useless, and will never supersede fuel Boilers. For other particulars regarding Boilers, see Heating and Stoking.

BOIS-PERDRIX. See Heisteria.

BOLBOPHYLLUM. See Bulbophyllum.

BOLETUS (from bolos, a mass; in reference to its massy or globular form). ORD. Fungi. The only species of this rather large genus demanding mention is B. edulis (see Fig. 261), which is considered an excellent article of food. It is easily distinguished, and is often of large size and somewhat unshapely; the pileus is usually of a dusky yellow or brownish hue, but sometimes brighter and more of a chestnut colour; the flesh is white, and does not change to a blue colour when cut (this is a very important characteristic, and should always be noticed). It is a species common in most districts, usually growing in woods, and appearing chiefly in the autumn.

FIG. 261. COMMON BOLETUS (BOLETUS EDULIS).

BOLEUM (from bolos, a ball; in reference to the shape of the seed-pods). ORD. Cruciferæ. An ornamental, hardy, evergreen shrub, well adapted for rockwork, in ordinary soil.

FIG. 262. FLOWERS OF BOMAREA CARDERI.

BOMAREA (derivation of name doubtful). ORD. Amaryllidaceæ. A genus of handsome half-hardy twiners, closely allied to Alströmeria, from which it is chiefly distinguished by its twining habit and some difference in the capsule. They are of comparatively easy culture, thriving in a compost of peat, leaf mould, loam, and sand, with good drainage. Manure water should be given during the season of growth. Although they make fine pot plants, their full beauty is only developed when planted out in the conservatory or greenhouse border. Propagated by seeds, or by careful divisions of the underground stem. In making a division, it is necessary to observe that the part taken has some roots by which to live till new ones are formed. It should be potted at first, and may, when established, be planted out or shifted on. Seeds may be[200] raised in a warm house without difficulty. They germinate in a few weeks; and when the young plants are 2in. or 3in. high, they should be placed separately in small pots, shifting them on as necessary, or planting them out. In favoured southern localities, several species have proved hardy, but they are much the best when grown in a greenhouse.

BOMBAX (from bombax, one of the Greek names for cotton; the pods are filled with a fine silky substance like cotton, but which it is impossible to spin into thread, in consequence of the edges being perfectly smooth). Silk Cotton Tree. ORD. Malvaceæ. A genus of large soft-wooded stove trees. Flowers[201] scarlet or white, large, usually rising laterally from the trunk or branches, either singly or in clusters. They grow best in a rich loamy soil.

[202]

BORDERS, FLOWER. Small beds, or a continuous bed, of greater length than width, skirting a wall or shrubbery, and containing plants of a heterogeneous character. They should be slightly raised above the surrounding level, and thoroughly drained. In the first preparation of the Border, it is most essential to deeply dig or trench the ground, thoroughly incorporating a large amount of well-bodied manure; and if the soil is very stiff, wood ashes or coarse sand should be well worked in with the manure. The best time to plant such Borders is in early autumn or in March.

Where, as is frequently the case, the Borders are only 2ft. or 3ft. wide, not more than two rows of plants, either in groups or singly, will be allowable. The tall plants or shrubs should constitute the background, with dwarfer subjects in front; but formal arrangements must be avoided. The object should be to secure a continuous succession of flowers. This would entail some little trouble at first, which, however, would be amply repaid by results.

No hard-and-fast rules can be laid down as to the arrangement of the plants, which depends on individual taste and means; but the best results are obtained when the border is mainly made up of hardy herbaceous perennials, as permanent occupants, assisted by liberal quantities of summer bedding plants, such as Dahlias, Fuchsias, Geraniums, Heliotrope, Tropæolums, &c., as well as many hardy annuals and biennials. By this means, a very varied and beautiful display may be maintained, especially if bulbs are used for early spring effect, such as Narcissi, Scillas, Snowdrops, Tulips, &c. Of course, the herbaceous perennials should be selected with much care, all weedy subjects being avoided, and variety in colour and time of flowering secured. Anything like a full list of these would occupy too much space for repetition here, but the following will be found very showy and useful: Achilleas, Aconitums, Anemones, Aquilegias, Armerias, Asters, Campanulas, Carnations and Picotees, Delphiniums, Dodecatheons, Doronicums, Fritillarias, Funkias, Gaillardias, Geraniums, Geums, Hollyhocks, Iberises, Irises, Liliums, Pæonies, Papavers, Pyrethrums, double and single, Ranunculus, Trolliuses, &c.

BORDERS, FRUIT. These should be well drained, and if not naturally so, the soil should be excavated from 3ft. to 5ft. deep, in order to form a bottom of stones, pieces of brick, clinkers, &c. Where it is convenient, draining pipes should be added, if an outfall in the vicinity can be secured. The base of the Border should be sloped to the front, where the pipes should be laid, and the bottom covered with draining material, thereby effectually preventing the fruit trees rooting deep, which is detrimental to healthy growth. Gross-feeding vegetables or flowers should not be grown on the surface, but shallow-rooting crops will generally do no harm. Many advocate the surface being kept free from crops of any sort, simply letting it be freely exposed; whilst others equally as strenuously condemn this plan. Where necessary, chalk or some other mineral constituent of good soil which is naturally absent, may be added; but much animal manure is rarely required. The depth and width of Border may vary for different fruit trees, but efficient drainage is in all cases important.

BORECOLE (Brassica oleracea fimbriata). An important division of the Brassica tribe, often cultivated in gardens under the name of Kale. It comes in very useful when hard weather has rendered cabbages, &c., unfit for use, as it endures cold better than most other green vegetables. Some are also grown as ornamental foliaged plants. Like all other plants of a similar description, they require rich soil, and they should be put out in June or early in July, as it is almost useless to plant this kind of vegetable after the middle of the latter month. To obtain the best results, the ground should be deeply dug and well manured; but it must not be full of crude manure at planting time, or it will make the plants too tender and succulent in wet seasons, with the result that the first sharp frost would cause them to rot. Good hard-stemmed plants are the kinds most needed, especially for crops required in spring, when green vegetables are scarce. Cultivation: Early in April, and again a month later for succession, the seeds should be sown thinly in nursery beds, not covering them too deeply. The soil should be in a friable condition, and it is an advantage if the first beds be made under a south wall. As soon as the seedlings appear, if they are too thick, they should be thinned, as those which are drawn up weak and spindly are useless. When large enough, they should be carefully planted out, choosing showery weather, if possible, for the operation. If it is necessary to plant them in dry weather, they must be well watered-in. The rows should be from 2ft. to 3ft. apart, according to the variety, and the plants 2ft. apart in the rows; or, if potatoes are planted wide apart, the Borecole may be arranged between them. Dead leaves must be cleared away from time to time, but no green ones should be broken off. When the tops are cut for use, the stems should not be denuded of foliage, as they will soon break again and form successional crops. The plants must be kept free from weeds. After April, the Kales are of little use; the stems may therefore be pulled up, and the ground planted with some other crop. They all require the same treatment, and at their various seasons come in equally useful.

Sorts. The distinct forms are somewhat limited, but being largely cultivated on the Continent as well as all parts of Britain on account of its hardy nature, the varieties of Borecole receive a large number of names that are either synonymous with, or indistinct from, a few well-known types. Dwarf Green Curled or Scotch is probably the best and most grown; other good hardy sorts are Asparagus Kale (this name is applied to several different kinds, the best one being in use very late in spring), Buda, Cottagers', Dwarf Purple, Imperial Hearting, Ragged Jack, and Tall Green Curled. Melville's Variegated and Variegated Borecole, amongst others, have fine ornamental foliage.

BORONIA (named after Francis Boroni, an Italian servant of Dr. Sibthorp, who perished from an accident at Athens; he collected specimens of many of those plants which are figured in the "Flora Græca"). ORD. Rutaceæ. Very elegant and useful shrubs, requiring similar treatment to ordinary greenhouse hard-wooded subjects, and much aided with a little extra heat in spring, when breaking into growth. Flowers pretty, pink-purplish, or white; peduncles terminal, but usually axillary on the extreme branches, one to many-flowered; pedicels furnished at the base and middle with two opposite, short bracts, jointed, commonly dilated under the calyx. Leaves opposite, simple, or impari-pinnate, entire, or a little serrulated, full of pellucid dots. They should be placed out of doors from July to the middle of September; the most convenient place for them is in pits, as there are then greater facilities for protecting them from heavy rains and thunderstorms. When first put out, Boronias should not be fully exposed, but in the course of a week they may remain open to the full influence of both sun and air. Potting should be performed once a year, as soon as the top growth ceases, as the roots then extend themselves in preparation for their next year's functions. The best compost for them is one of peat and maiden loam in equal parts, and about one-sixth sharp silver sand. Many cultivators, however, prefer a compost consisting of good fibry peat and silver sand, together with some pieces of charcoal, smaller or larger, according to the size of the pots used. The soil should be rammed firmly in the pots, which must be well drained. The leading shoots should be pinched, to ensure good bushy specimens. Propagation may be effected by young cuttings, or those made from the half-ripened wood; these should be put into a thoroughly drained pot of sandy soil, with 1in. of sand on the surface, and covered with a bell glass, which must be frequently taken off and wiped dry.[203] When in the cutting state, water must be very carefully given around the rim of the pot, without taking off the glass. If placed in a temperature of about 50deg., and shaded from bright noonday sun, they soon root, when they may be potted off singly into small pots, and plunged in sawdust, or cocoa-nut fibre refuse, in which situation but little water is needed. Pinching repeatedly, when young, is the only means to secure good ultimate growth. Air must be given on all possible opportunities.

BOTANY BAY TEA (and TREE). See Smilax glycyphylla.

BOTHY. A residence for under-gardeners, usually built behind the hothouses, or some high wall, in what is called a back shed. The place is too frequently a cramped, ill-ventilated hovel. A Bothy proper should be an independent structure, and fitted with modern conveniences; for, of all people, gardeners are the most susceptible to colds, &c. A library of standard horticultural and botanical works, as well as a few on other scientific subjects, and a moderate number of high-class books of fiction, one or more weekly gardening and other papers, should be supplied by the employer. During the winter months, for mutual improvement, lectures should be delivered, or papers read, by each gardener, on various subjects, after which a free discussion should take place upon the paper or lecture, by which means a great amount of good would be accomplished.

BOTRYCHIUM (from botrys, a bunch; in reference to the bunch-like disposition of the indusia). Moonwort. ORD. Filices. A genus of very interesting and pretty little hardy ferns.

BOTTLE-TREE. See Sterculia rupestris.

BOTTOM HEAT. This is usually secured by passing hot-water pipes through an air chamber, or a water tank, beneath a bed of plunging material. The covering of the tank or chamber is best made of slate. The heat must be regulated according to the requirements of the subjects grown; this is easily accomplished by using the valve. A thermometer should be placed in the tank or bed. Bottom-heat is indispensable for propagating plants from seeds and cuttings, especially in spring. See Heating and Hotbeds.

BOUGAINVILLEA (named after De Bougainville, a French navigator). ORD. Nyctagineæ. Gorgeous warm greenhouse or conservatory plants, comprising some of the most showy climbers in cultivation. Their beauty lies in the bracts, which envelop the small greenish flowers. B. glabra may be grown in pots, or planted out in the greenhouse borders; the others are best planted out, as they root very freely, and plenty of space would be occupied if allowed, but it is best to limit it, as they bloom much better. Strict training and pinching are not desirable, being prejudicial to the free production of bloom; indeed, the best plan is to allow the plants to ramble freely over the roof of a moderately high house, or along the upper portion of a back wall; they will then bloom profusely for several months in the year, provided proper attention be paid to watering, and that the plants are in a well-drained situation. In preparing a border for their reception, the first point to be considered is the drainage, which must be perfect. This is best effected by placing a layer of brick rubbish, 6in. to 9in. in thickness, communicating with the drain, by which means all sourness and stagnancy of the soil will be obviated. The bed should be excavated to a depth of 18in. or 2ft. Three parts turfy loam, and one part leaf soil, with the admixture of a liberal quantity of sharp gritty sand, will form a suitable compost for the culture of Bougainvilleas. The amount of sand incorporated must depend upon the quality of the other components, heavy loam requiring more than that which is more friable. The occasional incorporation of manure in the compost is not to be recommended; but a liberal application of liquid manure will be of material advantage, especially if the root space is limited. When the plants cease blooming each year—about November or December—they should be dried off and rested; and in February they should be closely spurred in, the same as with vines, and all weak leaders removed, so that strong wood only is left. When grown in pots, they must be started in brisk heat. They are easily increased by cuttings prepared from the half-ripened wood; these should be placed in sandy soil, in a brisk bottom heat, when they will soon root. Scale, red spider, and mealy bug are the only insects likely to infest the plants, and recipes for their destruction will be found under each individual name.

FIG. 269. FLOWERING BRANCH OF BOUGAINVILLEA SPECTABILIS.

> B. glabra (smooth).* fl., inflorescence panicled, smaller than that of B. speciosa, each branchlet producing cordate-ovate acute rosy[206] bracts, in threes. Summer. l. bright green, smooth. Brazil, 1861. This is by far the best species for pot culture, and forms a very showy plant when well grown.

> B. speciosa (beautiful).* fl., bracts large, cordate, delicate lilac rose, produced in immense panicles, which, in well grown specimens, are so freely produced as to entirely shroud the whole plant. March to June. l. ovate, very dark green, covered on the upper surface with small hairs. Stems branched, abundantly furnished with large recurved spines. Brazil, 1861. (F. M. i., 62.)

> B. spectabilis (showy). fl., bracts of a dull brick-red, shaded with scarlet. South America, 1829. It is very difficult to obtain bloom on this plant; and when flowers are produced, they are extremely ephemeral. The species is, for all practical purposes, much inferior to either of the foregoing. SYN. Josepha augusta. See Fig. 269.

BOURBON PALM. See Latania.

BOUSSINGAULTIA (named after Boussingault, a celebrated chemist). ORD. Chenopodiaceæ.

FIG. 270. FLOWERING BRANCH OF BOUVARDIA.

BOUVARDIA (named after Dr. Charles Bouvard, formerly superintendent of the Jardin du Roi, at Paris). ORD. Rubiaceæ. Handsome greenhouse evergreen shrubs. Peduncles terminal, three-flowered, or trichotomous and corymbose; corolla funnel-shaped, tubular, elongated, beset with velvety papillæ outside, and a four-parted, spreading, short limb. Leaves opposite, or in whorls; stipules narrow, acute, adnate to the petioles on both sides. These extensively cultivated plants are among the most useful for conservatory or greenhouse decoration (see Fig. 270. for which we are indebted to Messrs. Cannell and Sons), and the flowers are largely employed in a cut state. Perhaps only two are fragrant, viz., jasminiflora and Humboldtii. Cultivation: Presuming the grower to be commencing with young rooted cuttings, these should be potted off into a mixture of good fibrous loam, leaf soil, and sand, in equal proportions, to which may be added a small quantity of peat; they should then be placed in a temperature of from 70deg. to 80deg. until fully established in the small pots. It is necessary at this stage to stop the young plants back to the first joint, and as they continue to make fresh breaks, to keep on pinching them back during the whole period of cultivation, or until sufficiently bushy plants are produced. Many growers neglect stopping far too much, the result being ill-shaped and almost flowerless plants. The pinching, of course, can be regulated by the time the plants are required to flower; and it is unwise, in most cases, to stop them after the end of August. When the small pots are well filled with roots, the plants should be shifted into the flowering pots, viz., large 48-sized, which are quite commodious enough to grow very fine plants, a similar compost as in the first potting, with a little Standen's manure added, being used, and good drainage provided. A cool greenhouse, with a damp bottom for the pots to rest upon, and with a moist atmosphere, is the most suitable place in which to grow them during late spring and early summer, the moist air being very desirable as an effectual check to red spider, a pest very fond of the foliage, which it permanently disfigures. A cold pit or close frame is better during the summer months, as a moist atmosphere and cool bottom are then certain. Ventilation may be effected during the greater part of the day by tilting the lights below, and on fine nights they may be removed altogether. During bright sunshine, shading will be beneficial. All through the period of active growth, it is absolutely necessary that the plants should receive plenty of water, or they will surely suffer; and when the pots are filled with roots, occasional doses of manure water will be beneficial. Many cultivators plant them out about the end of June, in favoured situations, or in spent hotbeds, when they make very vigorous growth; and, if carefully pinched and watered, fine specimens are obtained. These are lifted in early autumn, with a good ball, potted, and kept shaded for a few days until the roots are again active, when they are taken to the house in which they are intended to bloom, and an enormous supply of flowers is secured. We have also seen Bouvardias planted out permanently in beds, in prepared pits, in which the winter temperature was not less than 55deg., with very satisfactory results; the quantity of bloom being very great. Of course, with the last-named treatment, it is essential to give the plants a rest and hardening-off after flowering, and when they are started into fresh growth to keep them well pinched and watered. Bouvardias are liable to the attacks of red spider and green fly. The former stands little chance of existence if the plants are kept well supplied with moisture; the latter may be destroyed by fumigating with tobacco. Mealy bug are also troublesome, and should be sponged off with a solution of Gishurst's Compound. Propagation: After flowering, and a slight rest and hardening-off, the old plants should be cut back, placed in heat, in a stove or cucumber pit, and freely syringed, which will cause them to break freely, and produce a good supply of cuttings. When the young shoots are from 1½in. to 2in. long., they are in the best condition for striking. It is not necessary that they should be cut off at a joint, as they will root from any surface of the stem; and, working economically, it is wiser to cut them off just above the first joint, as other shoots will speedily break out, which may, in their turn, be taken. Pots about 5in. across should have previously been prepared for the cuttings, by being well drained and filled with a mixture of good fibrous loam, leaf soil, and coarse sand, in equal parts, with a copious supply of sand upon the surface, into which the cuttings should be dibbled pretty thickly. A good[207] watering must be given without wetting, and thereby injuring, the foliage. The pots should be plunged in the cutting case, or in any bottom heat of about 70deg. or 80deg., and covered with a bell glass. All that is then necessary is to keep them moist and shady during sunshine, until they are rooted, which, as a rule, is effected in three weeks' time. When well established, they may be removed from the case, gradually hardened off, and finally potted singly into small thumb pots.

BRASSAVOLA (named in honour of A. M. Brassavola, a Venetian botanist). ORD. Orchideæ. A genus of epiphytal orchids, requiring the heat of an intermediate house. Flowers large, usually with narrow acuminate greenish petals and sepals, and a white lip, which is sometimes broad; column having a pair of great falcate ears on each side of the front, and eight pollen masses. Leaves solitary, succulent. They are of easy culture on blocks of wood, with a little moss, suspended from the roof. Water should be plentifully given during the growing season; at other times, a very small quantity will suffice. About seventeen or eighteen species have been introduced, of which the following only are worth growing:

> B. acaulis (stemless). fl. large; sepals and petals long, narrow, greenish and creamy-white; lip large, heart-shaped, and pure white; base of tube spotted with dull rose. September. l. very narrow, rush-like. h. 4in. Central America, 1852. (P. F. G. ii., 152.)

Vera Cruz, 1837. A very handsome fragrant species, somewhat difficult to flower, but this obstacle may be overcome by liberally growing during the proper season, and giving it a severe dry rest. (B. M. 4033.)

> B. lineata (lined).* fl. large, very fragrant; sepals and petals creamy-white; lip large, pure white. l. long, terete, channelled above, tapering to a point, very deep green. South America, 1850. (B. M. 4734.)

BRASSIA (named after Mr. William Brass, who was sent by Sir Joseph Banks to Cape Coast and the neighbouring districts as a botanical collector, at the end of the last century). ORD. Orchideæ. A genus of tropical American orchids, very nearly allied to Oncidium, with which, indeed, Reichenbach unites it. From this genus, however, Brassia may be distinguished by its simple inflorescence, elongated tail-like sepals, and short column, which is quite destitute of the side lobes or ears that form a marked feature in the species of Oncidium. There are about seventeen species, of which many are not sufficiently attractive to deserve the cultivator's attention. They will succeed either in pots or in baskets, the drainage of which must be perfect. They require to be potted in good fibrous peat, broken in pieces not less in size than a walnut, placed in the warm end of a Cattleya or Brazilian house, and supplied liberally with water during summer. In winter, they must still be kept in a tolerably warm place, and given sufficient water to keep the pseudo-bulbs from shrivelling. It is useless to dry off until shrivelling takes place, for experience assures us that when a plant shrivels it is generally safe to assume that it has been tried beyond its powers of endurance, and that its constitution has given way. Propagated by dividing the plants, when growth has commenced.

> B. antherotes (brilliant).* fl. 7in. in diameter from tip to tip of the sepals; sepals and petals yellow, brownish-black at the base, narrow, ⅛in. broad, tapering; petals 1½in. long; lip triangular, yellow, barred with brown; spike strong, about 2ft. in length. Tropical America, 1879.

> [210]

> B. caudata (tailed).* fl., sepals and petals yellow, barred with brown, from 4in. to 6in. long; lip broad and yellow, spotted with greenish-brown. When the plant is large and healthy, it produces numerous drooping spikes, 18in. long, and many-flowered. h. 1ft. West Indies, 1823 (B. R. 832.)

> B. Gireoudiana (Gireoud's). fl., sepals and petals bright yellow, spotted and blotched with deep red, produced in many-flowered scapes of singular and beautiful flowers during spring and early summer. This species much resembles B. Lanceana, but has larger flowers. Costa Rica. (R. X. O. 1, 32.)

FIG. 275. SINGLE FLOWER OF BRASSIA LANCEANA.

> B. Lanceana (Lance's).* fl., sepals and petals lanceolate and tapering, bright yellow, blotched with brown, or sometimes with deep red; lip wholly yellow, slightly spotted at the base, and much waved, deliciously fragrant; scapes radical, many-flowered.

L. longissima (long-sepaled).* fl., sepals deep orange-yellow, blotched and spotted, especially towards the base, with reddish-purple, and lengthened out into tail-like appendages, which, in well-grown examples, measure 7in. in length; petals about 2½in. long and ¼in. broad at the base, marked in the same manner as the sepals; lip about 3in. long, pale yellow, dotted and spotted towards the base with purple. August and September. Costa Rica, 1868. A magnificent variety.

> B. maculata (spotted).* fl. large; sepals and petals pale yellow, irregularly spotted with brown; the former being short compared with those of the other species; lip white, spotted about and below the centre with brown and purple. Spring and early summer. Jamaica, 1806. See Fig. 276. (B. M. 1691.)

> B. m. guttata (spotted).* fl. on spikes 2ft. or 3ft. long; sepals and petals yellowish-green, blotched with brown; lip broad, yellow, spotted with brown. May to August. Guatemala, 1842. SYN. B. Wrayæ. (B. M. 4003.)

> B. verrucosa (warty-lipped).* fl. large; sepals and petals greenish, blotched with blackish-purple; lip white, ornamented with numerous little green protuberances or warts, hence the specific name; scape many-flowered. May and June. Guatemala.

BRAVOA (named after Bravo, a Mexican botanist). ORD. Amaryllidaceæ. A pretty little graceful bulbous[211] plant, hardy in very sheltered positions, but in exposed situations requiring a slight protection in winter. It is an admirable plant for cool-house culture, and delights in a compost of light rich loam, leaf mould, and sand. Propagated by offsets, which are obtainable in autumn; or by seeds, which should be sown as soon as ripe.

BREVOORTIA COCCINEA. See Brodiæa coccinea.

FIG. 277. FLOWERING BRANCH OF BREXIA MADAGASCARIENSIS.

BREXIA (from brexis, rain; the large leaves afford protection against rain). ORD. Saxifrageæ. Excellent stove trees. Flowers green, in axillary umbels, surrounded by bracts on the outside. Leaves alternate, simple, dotless, and furnished with minute stipules. Stems nearly simple. They require a compost of two parts loam and one of peat, with the addition of a little sand, to keep the whole open. A liberal supply of water must be given at all seasons. Cuttings, with their leaves not shortened, strike readily in sand under a hand glass, in heat; or a leaf taken off with a bud attached will grow. Leaves as in accompanying illustration (Fig. 277), and long, narrow, spiny-toothed ones, are often produced on the same plant. Probably the two species enumerated below are simply forms of one. Well hardened off, strong growing plants of B. madagascariensis are very suitable for sub-tropical gardening.

> B. madagascariensis (Madagascar).* l. obovate or oblong, entire, while young minutely gland-toothed. h. 20ft. Madagascar, 1812. See Fig. 277.

BRICKS. In England, the standard thickness of brick walls is a Brick and a-half, that is, the length of one brick and the breadth of another. Thirty-two paving bricks, laid flat, will form one square yard of flooring; if set on edge, eighty-four will be required for the same space. The best Bricks for walls are those termed Stocks, which are well burnt. Grizzells and Place Bricks, being only partially burnt, are soft and not durable. In various parts of the kingdom, different clays and methods of manufacture cause a disparity in the weight and appearance of the finished article. Several forms are made to suit various purposes, but the standard size is 9in. long by 4½in. wide, by 2½in. thick, although, since the remission of the duty, some slight variations occur, owing to shrinkage and other causes. Fire Bricks are made of a particular kind of clay, which will stand intense heat when once burnt, and are used in furnaces and other places where durability under great heat is a desideratum. Fire-clay should always be used in place of mortar in building with these.

BRILLANTAISIA (named after M. Brillant). ORD. Acanthaceæ. A very small genus of erect, branching, stove evergreen shrubs. Flowers large, in terminal panicles; corolla ringent; upper lip falcate and overarching, with a trifid apex, the lower one large, spreading, shortly trifid. Leaves ovate-cordate, on long petioles. For culture, see Barleria.

> B. owariensis (Owarian).* fl. violet-blue; cymes sub-sessile, loose; panicles terminal. March. l. large, opposite, petiolate. h. 3ft. Western Africa, 1853. This plant, in its habit of growth, resembles some of the largest species of Salvia. (B. M. 4717.)

BRISTLES. Stiff hairs.

BRISTLY. Covered with stiff hairs.

BRISTLY-TOOTHED. Furnished with teeth like bristles, or with the teeth ending each in a bristle.

BRIZA (from briza, to nod). Quaking Grass. ORD. Gramineæ. A genus of ornamental hardy grasses. Panicle loose; calyx two-valved; corolla two-valved, awnless; exterior one ventricose, interior small and flat. Fruit adnate with the corolla. These extremely graceful plants delight in a soil composed of loam, leaf soil, and peat. Seeds may be sown in spring or autumn. For decorative purposes, the branches should be gathered as soon as full grown, and loosely placed in flower-stands, to dry. Tufts of these plants look extremely pretty on the rockery, or amongst hardy ferns.

> B. gracilis (graceful). Synonymous with B. minor.

> B. maxima (greatest).* fl., spikelets oblong-cordate, thirteen to seventeen-flowered; panicle nodding at the end. June and July. l. long, linear-acuminate. h. 1½ft. South Europe, 1633. See Fig. 278.

June and July. l. pale green, short, narrow. h. 8in. England (but very rare). An exceedingly pretty little annual or perennial grass. SYNS. B. gracilis and B. minima. See FIG. 279. (S. E. B. 1775.)

> B. spicata (spiked). A recent introduction from Brazil, described as being very graceful and quite distinct, having erect spikes about 8in. in height.

BROADCAST. A method of sowing seeds by means of the hand, scattering them over the surface of the ground as equally as possible. It is now superseded, for the majority of garden and field crops, by drilling, which not only economises the quantity of seed used, but greatly facilitates subsequent weeding and thinning out.

BROCCOLI (Brassica oleracea botrytis asparagoides). A cultivated variety of the Cabbage, having the young inflorescence condensed into a fleshy, edible head (see Fig. 280). To grow this popular vegetable successfully, it is necessary to have rich soil of a good depth, in an open situation, where the plants can have plenty of sun and air to keep them sturdy. They succeed the autumn Cauliflower, and are in season from November till May.

Soil. In preparing ground for Broccoli, trench, in the autumn, to the depth of from 1½ft. to 2ft., and during the process work in a liberal dressing of rotten farmyard manure. Ground which has carried a crop of Celery is very suitable for the strong-growing kinds, as, by planting where the Celery rows have been, the necessity of trenching is, to a great extent, obviated. Smaller kinds, however, need to be planted closer in order to obtain a profitable crop.

Cultivation. At the beginning of May, prepare seed beds on a south border, and sow the earlier and sprouting kinds. The later varieties would, perhaps, be best sown in April, but they must not be put in early and allowed to remain too long in the seed bed. Sow thinly, to get the plants as sturdy as possible; and, to prevent clubbing, work in a little soot or wood ashes on the surface of the beds. Care must also be taken to pick off the club excrescences at planting time, should there be any, and to destroy the grub inside. Clubbing is not so frequent in ground which has been well trenched, and where the plants are not allowed to suffer from drought. Showery weather should be selected for transferring them to their permanent quarters. If it is desired that they should succeed potatoes, they may be planted between every two alternate rows, and the latter crop can be removed when ready. Broccoli succeed best where the ground is firm, and not recently dug or manured. Planting with a crowbar is preferable to digging the ground afresh. If grown by themselves, a distance of from 2ft. to 3ft. should be allowed between the rows, and an equal distance from plant to plant. Some of the early varieties will, in favourable seasons, follow the later Cauliflowers, while the latest will not be fit for use until the following spring. The heads should be cut as soon as they are large enough; they will keep good for a week in a cold place, while a day or two might open them too much if allowed to remain on the plants. Broccoli which have to stand the winter are liable to injury from severe frosts, and some method of protection is necessary. Two plans are recommended for both large and small gardens, and either or both may be adopted, as found convenient. The first is to apply a covering of fern or other dry protective material, not using too much, but giving sufficient to break the rays of the sun, which, perhaps, do as much harm as the actual frost. The other plan is to take up the plants as soon as the flowers can be seen, and lay them in under a hedge or wall until required for use. In sheltered positions, or where there are trees to break the force of the wind, the covering with dry litter during severe weather will generally be found sufficient; still, a little precaution in lifting will frequently save a valuable crop. Broccoli should never follow a crop of any other kind of cruciferous plants, particularly Cabbage.

FIG. 280. BROCCOLI.

Sorts. Veitch's Self-protecting Autumn, Purple and White Cape, Grange's Early White, and Snow's Winter White. These are the best for autumn and mid-winter supplies. A good selection for spring and late purposes is Mitchinson's Penzance, Knight's Protecting, Cooling's Matchless,[213] Purple Sprouting, Model, Willcove, Leamington, and Cattell's Eclipse.

BRODIÆA (named after J. J. Brodie, a Scotch cryptogamist). SYN. Hookera. ORD. Liliaceæ. Pretty, slender, hardy, or in some positions only half-hardy, bulbs. The flowers are usually borne in large clusters or umbels; the prevailing colour is blue; coccinea is, however, an exception, the flowers being scarlet. The scape is usually straight and slender, but strong. Leaves from two to four in number, enveloping the part of the scape beneath the surface, and procumbent thereon. Most of them are of easy culture in rich sandy loam; if grown in pots, a mixture of loam, leaf soil, and sand, suits them well. Increased freely by offsets, which should be left undisturbed with the parent bulbs till they reach a flowering state, when they may be divided and replanted in autumn.

FIG. 282. BROMUS BRIZÆFORMIS.

BROMUS (from bromos, the Greek name for a wild oat). Ord. Gramineæ. B. brizæformis (see Fig. 282) is an elegant biennial grass, with drooping panicles of spikelets,[214] about as large as those of Briza maxima. It grows about 2ft. high, and is of very easy culture in common garden soil. Sow seeds outside in patches, in July, thinning out the plants when necessary. There are numerous other species belonging to this genus, but the above-mentioned is the only one worth growing in gardens. It forms a beautiful object in the mixed border, or among ferns.

BRONGNIARTIA (in honour of Adolphe Brongniart, a distinguished botanist, and one of the editors of "Annales des Sciences Naturelles"). ORD. Leguminosæ. Handsome greenhouse evergreen sub-shrubs, clothed with silky villi. Flowers large, purple; pedicels twin, axillary, one-flowered. Leaves impari-pinnate, with many pairs of leaflets, the terminal one not remote from the rest. They require a compost of sandy loam, leaf soil, and fibry peat, with perfect drainage. Cuttings of the young shoots, if firm at the base, will root if dibbled in sand, under a bell glass, in a cool house.

Cuttings of ripe wood, with their leaves on, root if placed in sand, in moist heat.

> B. Alicastrum. fl., catkins globose, stalked, twin, axillary. fr. coated. l. ovate-lanceolate. h. 6ft. Jamaica, 1776.

BROUGHTONIA (named after Mr. Arthur Broughton, an English botanist). ORD. Orchideæ. A very compact-growing stove evergreen, allied to Lælia, succeeding best if suspended from the roof on a block of wood, with a little moss; it requires a free supply of heat and water when in a growing state. Propagated by dividing the plant. The colour of the flowers is very distinct.

> B. sanguinea (blood-coloured).* fl. blood-coloured, rather large, disposed in a terminal panicle; scape divided; column distinct, or at the very base united with the unguiculate lip, which is lengthened at the base into a tube, connate with the ovarium. Summer. l. twin, oblong, seated on a pseudo-bulb. h. 1½ft. Jamaica, 1793. (B. M. 3076.)

BROUSSONETIA (named after P. N. V. Broussonet, a French naturalist, who wrote numerous works on Natural History). ORD. Urticaceæ. Ornamental fast-growing, deciduous, Mulberry-like trees. They require rather good open garden soil, and prove hardy in situations which are not very exposed. Propagated by suckers and cuttings of ripened wood, inserted in autumn, in a cool house; and by seeds, sown when ripe, or kept till the following April.

> B. papyrifera (paper-bearing).* The Paper Mulberry. fl. greenish, diœcious; males in pendulous, cylindrical catkins, each flower in the axil of a bract; females in peduncled, axillary, upright globular heads. May. l. simple, alternate, exstipulate, variously lobed or entire, hairy, large. h. 10ft. to 20ft. China, 1751. There are several varieties, differing in the shape and character of the leaves. (B. M. 2358).

BROWALLIA (named in honour of John Browall, Bishop of Abo, who defended the sexual system of Linnæus against Siegesbeck, in a book entitled "Examen epicriseos," &c., 1739). ORD. Scrophularineæ. A genus of handsome shrubs or herbs. Flowers blue or white, axillary and terminal; corolla salver-shaped, resupinate from the contortion of the peduncle; tube fifteen-nerved, ventricose at top. Leaves alternate, stalked, ovate in outline. They thrive best in a rich, open, sandy soil. To have strong plants in bloom by Christmas and after, seeds should be sown in July, in pans or pots of light rich sandy soil, and kept in a close frame, or hand light, where they can be shaded till germination takes place. When large enough to handle, the seedlings may either be pricked out, three in a pot, or potted singly, according to the size of the specimens required. In the former way, they form fine masses for conservatory or greenhouse decoration, or to cut from; and in the latter, they are very suitable for window recesses, &c. After potting, they should be stood in a pit or frame, and syringed every morning and evening, to ward off attacks of insect pests. An abundance of well-diluted liquid manure is required as soon as the flower-buds appear. To keep the plants dwarf and bushy, it will be needful to stop them about three times during the remainder of the summer and autumn, keeping as near the glass as possible; they should be housed by the end of September. These elegant little greenhouse annuals are unrivalled for affording choice, neat sprays for bouquets during the winter and early spring months, or for growing as pot plants, to furnish warm greenhouses or sitting-room windows. Many of the species and varieties are largely employed for summer decoration of the flower garden, with highly satisfactory results; for this purpose, seeds should be sown in gentle heat early in spring, and the plants transferred to the flower borders late in June, or early in July, having been previously encouraged in pots, and well hardened off.

> B. abbreviata (shortened). fl. light red; pedicels shorter than the calyx; calyx campanulate, with teeth as long as the tube. l. oval, hairy when young, quite glabrous when mature. 1852. (R. G. 94.)

> B. demissa (low).* fl. of a bright but pale blue colour, sometimes red or purple; peduncles axillary, one-flowered, downy. June. l. ovate-oblong, acuminated, oblique at the base. h. 6in. to 1ft. Panama, 1735. (B. M. 1136.)

FIG. 283. BROWALLIA ELATA, showing Habit and Flower.

> B. elata (tall).* fl. deep blue; calyx beset with glandular hairs; peduncles axillary, one or many-flowered. July. l. oval, acuminated. h. 1½ft. Peru, 1768. Of this extensively-grown species there are two varieties, one with white flowers, and the other, grandiflora, with pale blue, both of which are well worth growing. See Fig. 283. (B. M. 34.)

> B. grandiflora (large-flowered).* fl., corolla with a greenish-yellow tube, which is clothed with glandular villi, and a white or very pale lilac limb; peduncles one-flowered, axillary, racemose at the tops of the branches.

[215]

BROWNEA (named after Patrick Browne, M.D., author of a History of Jamaica). ORD. Leguminosæ. Very handsome stove evergreen trees or shrubs, allied to Amherstia. Flowers of a rose-scarlet colour, rising in fascicled heads from the axillary buds. Leaves abruptly-pinnate, when young flaccid, and with the leaflets revolute at the edges; leaf-bud long and stipulaceous. All the species are well worthy of the most extensive cultivation. A mixture of loam, peat, and sand, is a soil well adapted for them, and great care should be taken not to over-water the plants in winter, as too great a supply will be sure to kill them. Propagated by cuttings, taken from ripened wood, planted in a pot of sand, and placed under a hand glass, in a moist heat.

> B. Ariza (Ariza).* fl. richest scarlet, produced in a large, globular, drooping head of immense size.

BRUNFELSIA (named after Otto Brunfels, of Mentz, first a Carthusian monk, and afterwards a physician; he published the first good figures of plants in 1530). SYN. Franciscea. ORD. Scrophularineæ. Elegant free-flowering stove evergreens. Flowers sweet-scented; corolla large, funnel or salver-shaped, with a long tube, and a flat, five-lobed, obtuse, nearly equal limb. A light rich soil, or a compost of loam, leaf soil, and peat, is necessary to grow these plants successfully. Propagated by cuttings, planted in sand, and placed under bell glasses, in a moderate heat. When rooted, they should be placed in small pots, in a compost somewhat more sandy than that already mentioned. While growing, they require to be kept in a moist stove temperature, and should be hardened by placing them in a drier, and somewhat cooler, temperature after each growth is completed; the pots should be changed as often as the roots become thick around the ball of earth. The larger plants flower freely, and should be slightly pruned in annually, before commencing their new growth, thus securing neat and compact specimens. Repotting should be effected directly they have done flowering. The plants should then be placed in a temperature ranging from 60deg. to 68deg., and both the roots and foliage liberally supplied with water. When flowers appear—about October or November—the syringing must be less frequently performed. At this period, if it be desirable to prolong the flowering season, the plants should be removed to a temperature of about 48deg. A few administrations of weak liquid manure during the growing season are of great value.

> B. acuminata (taper-pointed-leaved).* fl. bluish-violet, few, sub-cymose, terminal. April. l. oblong, acuminated, attenuated a little at the base, glabrous; bracts lanceolate, acuminated, glabrous. h. 1ft. to 2ft. Rio Janeiro, 1840. (B. M. 4189.)

> B. americana (American).* fl. first yellow, then white, very sweet-scented; axillary flowers solitary, terminal ones numerous. June. l. obovate, elliptic, acuminated, longer than the petioles. h. 4ft. to 6ft. West Indies, 1735. There are narrow and broad-leaved varieties of this species. (B. M. 393.)

BRUNIA (named after Corneille de Bruin, better known under the name of Le Brun, a Dutchman, a traveller in the Levant). ORD. Bruniaceæ. Elegant little greenhouse evergreen Heath-like shrubs, more or less branched, with the branches in whorls, erect or spreading. Flowers capitate, furnished with three bracts each, or sometimes deficient of the two lateral ones. Leaves small, closely imbricate. They require a compost of peat and sand, with a little leaf soil added, firm potting and good drainage. Cuttings of young shoots root freely in sand, under a hand light, in summer.

> B. nodiflora (knot-flowered).* fl. white; heads globose, size of a cherry, on the tops of the branches. July. l. lanceolate, awl-shaped, trigonal, acute, smooth, closely imbricate, not ustulate at the apex. h. 1ft. to 3ft. Cape of Good Hope, 1786. See Fig. 284.

BRUNIACEÆ. An order of much-branched Heath-like shrubs, usually having small leaves, which are crowded and entire. Flowers in terminal heads; petals five, alternating with the lobes of the calyx. The typical genus is Brunia.

BRUNONIA (named after Robert Brown, the most eminent botanist of his time). ORD. Goodenoviæ. A stemless greenhouse perennial herb, with the habit of Scabiosa, downy from glandless simple hairs. Flowers distinct, with a whorl of five membranous bracts; corolla blue, marcescent. Radical leaves quite entire, spathulate; scapes undivided, each bearing one head; head hemispherical, lobate; lobes involucrated by foliaceous bracts. It thrives in a compost of decayed manure, or leaf soil and peat, with a little loam added; thorough drainage is necessary. Propagated by divisions, in early spring, previous to repotting.

> B. australis (southern)* is the only species known to be in cultivation. h. 1ft. New Holland, 1834. (B. R. 1833.)

BRUNSVIGIA (named after the noble House of Brunswick). ORD. Amaryllideæ. Very showy greenhouse bulbous plants, from the Cape of Good Hope. Flowers red, on very long pedicels. Bulbs large. Leaves broad, horizontal; perianth with an evident longer or shorter tube, curving upwards, funnel-shaped, deeply six-parted, deciduous; segments sub-equal, many-nerved, flat, and recurved at the apex; stamens on the tube much curved upwards; scape appearing in summer without the leaves; umbels many-flowered. Propagation is effected by offsets, of which the large bulbs produce but few. These, when secured, may be removed after reaching some considerable size, carefully potted in a mixture of sandy loam and peat, with good drainage, and kept tolerably warm and close until established; water must be given but sparingly until root-action has commenced. The best place for growing the offsets into a flowering size is on a shelf near the glass, in a temperature of from 50deg. to 55deg. With an abundance of water while growing, and kept dry while semi-dormant, thus allowing them a rest, the bulbs will speedily increase in size; but it may be years before flowers are produced. Culture: This may be divided into two periods—one of growth, and one of rest. After the latter period, they should be allowed to start into fresh growth, without stimulation, and, as soon as started, liberal supplies of water should be given, and a genial temperature of from 60deg. to 65deg. maintained, to make them grow vigorously. Good-sized pots are also necessary, with a mixture of loam, peat, and sand, in equal parts. They are usually confined to the greenhouse, or warm conservatory, but are sometimes successfully grown in a south border at the base of a wall, planted out in a pit, upon which the lights may be placed in winter, and matted if necessary, as they cannot endure frost. A good depth of soil, consisting of fibrous loam, peat, and sand, in equal proportions, with good drainage, should be prepared. In all cases, the bulbs should be planted somewhat deeply. One of the most satisfactory methods of ensuring the flowering of these plants consists in subjecting the bulbs, when at rest, to a hot dry heat of 70deg. or more, which thoroughly ripens them; but, after this treatment, it will be necessary to encourage the after-growth to the fullest possible extent.

FIG. 285. BRUSSELS SPROUTS.

BRUSSELS SPROUTS (Brassica oleracea bullata gemmifera). A cultivated variety of the Cabbage (Fig. 285). Leaves blistered. Stems covered with small, close[217] heads. To secure this vegetable in its best form, it must be grown on deeply-worked and rich ground. In addition, the seeds should be obtained from a good source, as there are many spurious stocks in cultivation. Plenty of room must be allowed the plants to develop, and the tops and leaves should not be removed till after the sprouts are gathered; dead leaves, of course, excepted. It is a bad plan to plant Brussels Sprouts amongst potatoes or other crops, as they become unduly weakened, and never give such good returns as when grown by themselves.

Soil and Cultivation. In February, and early in March, sow thinly in a cold frame, or carefully prepare seed beds on a warm south border. As soon as the plants are large enough, prick them off into prepared soil, to grow on; about the end of April, transplant into a piece of rich ground, which has been previously prepared for them, setting in rows from 2ft. to 3ft. asunder, and 2ft. apart in the rows. The earlier the plants are put out, the better; and they should be watered-in when planted, so that they receive as little a check as possible. They must be kept clear of weeds, and earthed up as soon an they get a good size. During severe frost, some light dry litter may with[218] advantage be thrown over them for protection; and the less they are interfered with when frozen, the better.

Sorts. The Imported is the best strain for general use; other good sorts are: Sutton's Matchless, The Aigburth, and Scrymger's Giant.

BUDDING. This process consists of taking an eye or bud attached to a portion of the bark, and transferring it to another and different plant; it is an operation almost confined to woody plants, but has been practised with more or less success upon herbaceous perennials. The stock should not be budded unless the sap is in circulation, which is assured if the bark will detach itself easily, when gently lifted, from the wood.

There are many ways of performing the different systems, in preparing and inserting the Buds, &c., and all may prove more or less successful if undertaken when the Buds and stock are both in a suitable condition. The principal methods are Shield or T-budding, including the Circular, Square, and Inverted forms; Flute or Tube-budding, and Annular or Ring-budding.

The first-named method, which is fully described below, is very extensively practised for propagating Roses and stone fruits. It is also coming more in use for the propagation of many other fruit trees, including Apples and Pears, especially new or scarce varieties, as the great advantage of making use of many more of the eyes, to form separate trees, is thereby attained. In large nurseries, where skilful propagators are employed, thousands of trees are annually budded, the majority of them with very successful results. It is, in most cases, preferable to purchase established fruit trees, as cultivators require the produce much quicker than they could get it by propagating trees themselves. The same system of Budding is, however, applicable for increasing Roses; and this may be adopted with every chance of success by even a cottager, if he takes the necessary care in performing the work.

Rare varieties of ornamental deciduous trees are largely propagated in this way; for instance, many of the Acers, Elms, Horse Chestnuts, &c. Evergreen shrubs, such as Rhododendrons and Hollies, are also rapidly increased in some establishments by this means.

In the case of fruit-frees, plump wood Buds must be selected, from medium-sized branches. On some sorts these are scarce, the majority being Flower-buds, and it is rather difficult to distinguish between them at the Budding season. The best time for the operation is from June to the end of August; but surrounding influences, condition of Buds, stocks, &c., must be taken into account. Clean cuts, with gentle and skilful handling, are even more important in the Budding of stone fruits than of Roses or other plants, and the ties should be lightly but firmly made. In all cases, the operation must be performed as quickly as possible, as both Bud and bark are injured if exposed to the air for any length of time.

FIG. 287. FIG. 288.

To proceed with the ordinary system of Shield-budding, the stock (see Fig. 287 a) should first have a longitudinal and[219] a transverse incision made in the bark, the former about 1in. long. Next, the Bud should be prepared, removing half the leaf (see Fig. 288). Hold the branch with the left hand, and pass the knife from about ½in. below, gradually upwards and inwards under the Bud, bringing it out in a similar way at a somewhat shorter distance above. A portion of wood will also be taken out, and this is generally removed the opposite way to that in which the Bud has been cut. By skilful Budders, it is removed by a sort of twitch from either end. Great care must be taken not to pull out the base or root of the Bud at the same time, as this would render it useless. Should the whole come out together, leaving a hollow place under the eye of the Bud, it must be thrown away, and another prepared. The Bud being ready, loosen the bark at the point where the incisions meet, with the ivory knife handle, and insert it by means of the piece of leaf attached. It must then be tied in with soft matting or bast, to exclude air, but not tight enough to injure the bark. Shading from bright sun is advisable for a few days afterwards, and, as soon as the union takes place, the ties must be frequently examined, and loosened if necessary. Some prefer Budding late in the season, in order that the Bud may remain dormant during the winter, and breaking stronger the following spring. Occasionally, they are inserted in spring, just at the commencement of growth. The stocks of the Summer-budded trees should only be allowed a moderate amount of foliage during the autumn, and should be cut back to the established Bud before growth commences in spring.

Square and Circular Shield-budding consists in cutting out a piece of bark of either shape from the stock, and inserting another piece of exactly the same size, containing a Bud, and covering with a bandage, or piece of sticking plaster, all except the eye. This mode is seldom made use of. Inverted T or Shield-budding is preferred in the south of France for propagating Orange-trees, but is not otherwise much used. The only difference is that the transverse incision is made below, instead of above, the other, and the Bud inserted upwards, making it fit with the bark at the point where the stock is cut across.

FIG. 289.

Flute-budding is sometimes used, and answers well for some trees (see Fig. 289). A cylinder of bark is removed from the stock, and one of a similar size from the scion. containing Buds, is fitted in its place, being carefully made air-tight by means of a bandage or grafting wax. Some prefer splitting the hark, as shown in the illustration. and laying it over the tube or cylinder; but the parts cannot be fitted so well as when it is removed.

Ring Budding. By this mode, it is not necessary to cut off the top of the stock. A ring of bark may be removed from any convenient part (see Fig. 290 b) and replaced with one containing eyes (see Fig. 290 a). The latter should be taken from a little larger branch than the stock, as the bark could then be made to fit better. As in Flute-budding, air must be excluded by means of adhesive paper and bandages or grafting wax.

Budding operations may be performed at any time during the season; but dull cloudy weather, and morning or evening, are most suitable. If the branch, containing Buds, cannot be obtained as required for use, the ends may be placed in water, to keep them fresh; but unnecessary delay should be avoided.

FIG. 290.

FIG. 291.

Stocks for Budding upon. For the Cherry, the Wild Gean, and seedlings from the Morello. make capital stocks for tall trees and those of moderate growth; and the Mahaleb, or Perfumed Cherry, for small trees for pots, bushes, pyramids, or cordons. For the Plum, the Mussel, Mirabelle, Magnum Bonum, St. Julian, &c., are mostly used for stocks, the Mirabelle being best for small trees. Peaches and Nectarines are generally budded on the Mussel, St. Julian, or Mirabelle Plums; the last are best for dwarfs. The Apricot is budded on the Mussel or Mirabelle Plums, for small plants; and the St. Julian Plum for standards. In France, the Damas Noir, or Black Damask, and the Cerisette, are also used. They should all be raised from seeds, and not from suckers. Seeds for raising plants for stocks may be sown as soon as ripe; but where quantities are used, the stones are thrown into heaps, so as to slightly ferment during winter. In the spring, they are sown in drills or beds, and transplanted the next year in rows 2ft. or 3ft. apart. and 10in. or 12in. from plant to plant. The dwarfs are generally budded the second year, and the standards the third or fourth. Dwarf trees are budded from within a few inches of the[220] ground to 1ft. above; standards and riders from 3ft. to 9ft.; cordons, pyramids, &c., can hardly be budded too low.

Rose Budding. Propagation of Roses by Budding is very extensively practised both with standard trees and dwarf plants. It is perhaps easier and more certain to succeed with these than with fruit trees; but the mode adopted is precisely the same—that of the shield-shaped Bud with the core, or root, and the bark attached. For standards, the common briar of the Dog Rose is the best. The earlier these are obtained and planted in November, the better, as roots are then formed at once. For dwarf plants, the Manetti stock is mostly used, being easily obtained and had in proper condition almost at any time when Buds are ready. Plants on this stock do not succeed in all soils, and suckers are also very liable to be produced. Budding on the seedling briar is attended with good results, and is practised more than hitherto. The De la Grifferaie stock is also used, more for Tea Roses than others, and is considered by some to produce better plants than the Manetti. The shoots on standard briars should be reduced to about three of the strongest, selected as close together as possible, and near the top, the briars having been previously cut back the desired height at planting time. Two Buds are sufficient for a good head; but, for certainty, three may be inserted. Fig. 291 represents a tall briar with three shoots; a shows the shoot slit for the Bud; b, the Bud inserted; c, the Bud tied in. Fig. 292 is a branch showing Buds, the lowest ones of which are most suitable, being in firmer wood. Those at the top are often useless. Fig. 293 represents a Bud taken from Fig. 292, a, b, and Fig. 294 gives an idea of how the wood is removed. As previously remarked when describing the system, experienced Budders remove the wood from either end. Fig. 294 shows its removal from the lower end.

FIG. 292.

FIG. 293. FIG. 294.

Budding as close as possible to the main stem is most desirable. Raffia grass is superior in every way for tying, which should be performed as soon after the Bud is inserted as possible. It requires much care, and, of course, the Bud itself must be entirely free. As soon as the Buds swell, the tying material should be loosened, and the top of the stock cut back to the level of the budded shoot. By Budding late, the Buds lie dormant till the next spring, and the necessity of tying the young shoots is dispensed with for that season. The shoots of the briar in advance of the Rose Buds must be cut back, as shown in Fig. 295, so soon as the Buds are safely established. The Manetti and other dwarf stocks are budded on the main shoot nearly close to, or underneath the ground, and if low enough to cover part of the rose stem when grown, the latter often roots as well and assists the stock. Being small, they may be grown in pots and removed to the required position at any time.

FIG. 295.

Dog Roses, used for standards, are usually collected from hedgerows, and sold at about 8s. per hundred. Manetti stocks are increased by cuttings, which, after making one season's good growth, will be fit for use. Briars are raised from seed, which may be collected from hedges, and sown in the autumn, in drills. The seedlings should be transplanted the first year after sowing, and the following season they will be ready for working.

BUDDING KNIVES. The best Budding Knives are those manufactured by Messrs. Saynor and Co., and Messrs. G. Hall and Son. They are made with handles of ivory, shaped in different ways at the end, for the purpose of opening the bark, in order to insert the Bud. Some of the blades are made with the edge rounded at the point, so as to cut the bark without the knife entering the wood underneath (see Figs. 296 and 297). Others, which may be used for Budding, and are much better for ordinary use for cutting flowers, &c., are made with the edge of the blade carried to a point, as in ordinary knives (see Figs. 298 and 299). Another form has the handle made of some other material, and a piece of ivory inserted for opening the bark; this is represented in Fig. 300. The first-named is the best, if required for Budding only; the second is the most useful for ordinary purposes, and answers admirably for Budding as well. None of the other shapes have any material advantages over these.

BUDDING KNIVES.

BUDDLEIA (named after Adam Buddle, who is so often mentioned in Ray's "Synopsis"; his collection of dried British plants is preserved in the British Museum). ORD. Loganiaceæ. A large genus of stove, greenhouse, or half-hardy shrubs. Flowers small, often tomentose, axillary, spicate, capitate, or thyrsoid; calyx equally four-toothed; corolla tubular-campanulate, regular; limb spreading, four-toothed. Leaves opposite, reticulately veined. Branches quadrangular.

[221]

The species most extensively grown is B. globosa, which, among all our other shrubs, is quite unique; but it is only in the southern or favoured counties of England where it can be fairly termed hardy. It is readily propagated by cuttings or by seeds. The latter should be sown in a gentle heat the spring following the ripening, when they will vegetate pretty freely. With careful treatment and nurturing in pots for the first winter, in a frost-proof pit or house, they may soon be grown into elegant plants. Cuttings of the ripened wood, put in under bell glasses or hand lights, in a cool but frost-proof pit, will root slowly during the winter. They will root all the surer and quicker if each cutting has a heel of older wood attached to that of the current year's growth. They are best inserted in fine sand or in very sandy soil, and require but little water until rooted. As soon as fairly calloused over or rooted, their further progress may be much advanced by potting them off, and plunging them in a bottom-heat of 60deg. or 65deg. This is by no means an essential to secure success, but it hastens it, and promotes growth in an extraordinary manner. The surface temperature should range about the same as the bottom-heat. Under such treatment, the plants will be quite fit to place out about the middle of July. A warm, sheltered situation should be chosen, and a light, rich soil prepared for them; and if dry weather ensues, they only require water. South or west walls are, without doubt, the best situations for them. In all cool or unfavourable localities, much may be done to ensure success by planting on a dry bottom, and on poorish soil. A loose, free-and-easy style of training suits the plants best. This enables them to yield a great number of their peculiarly formed, distinct, and beautiful flowers; whereas, anything like a close, trim course of pruning or of training reduces the flowers to the lowest number.

Throughout the southern parts of England, and, indeed, in many places in the north, B. globosa makes an excellent bush for the shrubbery. It is only during severe winters that it gets badly cut.

For the other presumably hardy species much the same plan as the foregoing may be adopted. The greenhouse and stove kinds may have the same routine of culture usually employed with plants requiring similar temperatures.

BUDS, FLOWER. These are developed like Leaf-buds, from which they differ chiefly in containing one or more incipient flowers within the leaves—the flowers being wrapped up in their own floral-leaves, within the ordinary leaves, which have their outer covering of scales. If a Bud be gathered from a Lilac or Horse-chestnut very early in spring, all the rudiments of the future flowers and leaves will be found within it, though the Bud itself may not be more than half-an-inch long, and the flowers not larger than the points of the smallest pins.

BUDS, LEAF. These consist of rudimentary leaves, surrounding a growing vital point, and appear like a collection of scales arranged symmetrically one above the other. Leaf-buds universally originate in the horizontal or cellular system, and are formed under the bark at the extremity of the medullary rays, and at the margin or on the surface of leaves, whether perfect or rudimentary. Deciduous trees lose their leaves, but in the axil of each a little Bud previously forms, from which fresh leaves expand the following spring. In some cases, as in the Horse-chestnut, the Buds are covered with a gummy exudation. In Privet-trees, Leaf-buds are generally smaller and more elongated than Flower-buds.

BUETTNERIA (named after David Sigismund Augustus Byttner, once a Professor of Botany in the University of Göttingen). ORD. Sterculiaceæ. Erect or scandent stove or greenhouse shrubs. Flowers small, usually dark purple; calyx and corolla valvate; umbels simple, disposed in something like racemes or panicles, rarely in corymbs. Leaves simple. All are of easy culture in a compost of loam and peat. B. dasyphylla, hermanniæ-folia, microphylla, and scabra, are occasionally met with, but they are hardly worth growing.

BUETTNERIEÆ. A section of Sterculiaceæ.

BUFF-TIP MOTH (Pygæra bucephala). This large and beautiful Moth is very common in many districts; it is easily recognised by the buff-coloured tips of the fore-wings—whence its common name; the head, and body between the wings and abdomen, are ochreous. According to Newman's "British Moths," "the caterpillars, when full grown, are about an inch and three-quarters long, and sprinkled with silky hairs; the general colour yellow, with black head, black lines running from the head to the tail, interrupted by a transverse orange band on each ring, and a black horny plate above the tail segment." They feed on the leaves of the Lime, Elm, and Oak, among other trees, and apparently the only remedy is that generally adopted in exterminating caterpillars, viz., to shake the branches which are infested, when the pest will be quickly dislodged, and fall to the ground. Miss Ormerod is of opinion that "as the caterpillars come down the tree to the ground for their change to chrysalids, it might be worth while to throw a few spadefuls of gas-lime, or of anything they would not cross, in a circle at about a yard from the tree; or a rough band of any material soaked in tar, or tar and oil, which would keep wet longer, would stop them from straying off ... and they might be cleared in sufficient numbers so as to considerably lessen future attack." This plan of prevention deserves a trial in any place where the destructive caterpillars of these Moths abound. It is almost a hopeless task to destroy them altogether when once established on the trees, such specimens as large Oaks being often almost or wholly denuded of foliage.

BULBIFEROUS. Bearing bulbs.

BULBINE (from bolbos, a bulb). ORD. Liliaceæ. A genus of rather pretty hardy, or nearly hardy, herbaceous or bulbous plants, allied to Anthericum. Flowers showy, fragrant; perianth with spreading segments. Leaves somewhat fleshy, narrow. Stems short. They are all of easy culture in a compost of sandy loam. The bulbous-rooted species are increased by offsets, and the herbaceous sorts by suckers and divisions. The only species which can be grown satisfactorily in the open air is B. annua. All the others should be grown in the greenhouse, but may be placed in the open during the summer months.

> B. annua (annual). fl. yellow; scape racemose. May, June. l. fleshy, subulate, rounded. h. 9in. Cape of Good Hope, 1731. An annual species, the seeds of which should be sown in a gentle heat during spring, and the seedlings may be transplanted to the open when large enough to handle. SYN. Anthericum annuum. (B. M. 1451.)

> B. caulescens (caulescent).* fl. yellow. March. l. fleshy, rounded. Stem shrubby, erect, branched. h. 2ft. Cape of Good Hope. 1702. A shrubby species, which should be propagated by cuttings, placed under a hand glass. SYN. B. frutescens. (B. M. 816.)

> B. frutescens (shrubby). Synonymous with B. caulescens.

BULBOCODIUM (from bolbos, a bulb, and kodion, wool; referring to the woolly covering of the bulbs). ORD. Liliaceæ. TRIBE Colchiceæ. A very pretty little bulbous plant, much resembling the Crocus, from which it differs principally in having a superior ovary and six stamens. It is amongst the earliest of spring-flowering plants, the flowers preceding the foliage; and, like the majority of bulbs, delights in rich sandy loam. In such positions, they multiply rapidly from offsets. It is a good plan to take up the bulbs, divide, and replant them every second year, selecting in autumn, and renewing the soil or planting in new positions. Few plants prove more welcome in the garden, in February, than B. vernum, either in beds, patches, or masses.

FIG. 301. BULBOCODIUM VERNUM.

> B. vernum (spring).* fl. violet-purple, with a white spot on the claw; long, tubular, funnel-shaped, two to three from each bulb; preceding the appearance of the leaves. Very early spring. l. usually three in number, broadly strap-shaped, concave, and surrounded at the base by well-developed sheaths. Bulb black, oblong. h. 4in. to 6in. Spain, 1649. See Fig. 301. There is a variety with the leaves striped white, which is also desirable.

BULBOPHYLLUM (from bulbos, a bulb, and phyllon, a leaf; referring to the leaves issuing from the apex of the pseudo-bulbs). SYNS. Anisopetalum, Bolbophyllum, Tri-brachium. ORD. Orchideæ. Of this rather large genus of orchids but few are worth cultivating except as curiosities. Racemes long or spike-like, very rarely one-flowered or sub-umbellate; sepals usually nearly equal and free; lip jointed to the foot of the column. They are of easy culture when grown on small blocks of wood with a little moss, and suspended in a warm part of the house; the roots require a good supply of water. Propagated by dividing the pseudo-bulbs.

The following comparative few of the aggregate number of species already introduced are really all that are worth the cultivator's attention; what the botanist often regards as being very pretty, &c., does not always appear such in the eyes of the grower.

> B. barbigerum (bearded).* fl., sepals and petals greenish-brown; lip covered with dark-coloured hair, and so loosely attached at the base as to be moved with the slightest breath. Sierra Leone, 1835. A curious dwarf-growing plant, with dark green leaves and pseudo-bulbs. (B. R. 1942.)

> B. Beccarii (Beccari's). fl. light brownish and painted with violet; lip brown, with a violet hue, proceeding from a rhizome at the base of the leaf (just below the small pseudo-bulb), and at once turning downwards; racemes dense, cylindrical, nodding. l. three, 25in. long, 18in, across, very thick. Rhizome 20in. long. Brazil, 1879. A remarkable and gigantic climbing species; the odour of this plant is intolerably fœtid and the leaves are larger than those of any other known orchid. This species requires plenty of heat. (B. M. 6517.)

> B. reticulatum (netted-leaved).* fl. in pairs, white, striped inside with purple; lip spotted with the same colour. l. somewhat heart-shaped, with the nerves of a deeper green than the rest of the leaf, giving it a beautifully reticulated appearance. Brazil, 1866. Perhaps the handsomest of the genus. (B. M. 5605.)

> B. saltatorum (dancing). fl. greenish-brown, lasting some time in perfection. Winter. h. 6in. Sierra Leone, 1835. (B. R. 1970.)

> B. siamense (Siamese).* fl. pale yellow, striped with purple; lip yellow, streaked with purplish lines. A very pretty species, closely allied to B. Lobbi, but with longer and stouter leaves. Pseudo-bulbs ovate. Siam, 1867. Should be grown in a pot of peat and sphagnum.

BULBOSTYLES (from bolbos, a bulb, and stylos, the style). ORD. Compositæ. A. small genus of stove evergreen plants, now referred to Eupatorium.

BULBS. A Bulb is formed upon or beneath the ground, and is a swollen stock, consisting, in the first place, of a more or less fleshy disk, which below gives rise to the roots; secondly, of more or less fleshy coats, or scales, borne on the disk; thirdly, of a more or less central shoot, equally borne by the disk, protected by the coats or scales already mentioned, and formed of rudimentary leaves and flowers. In some instances, small Bulbs, called Cloves, are formed at the base of the scales of the original Bulb; these are destined to reproduce the plant. Shallot and Garlic are good examples. Bulbs are, in fact, storehouses, husbanding the strength and energy acquired by the plant during one season, for the exigencies of the next. They are classified under two sections—Scaly and Tunicated. In the former, the scales of the Bulb are imbricated, as in the Lily; in the latter, they form continuous coatings, one within the other, as in the Hyacinth, &c. In several Lilies, young Bulbs are found growing in the axils of the leaves, when they are known as Bulbils. Bulbs is also a popular term given to Dutch Flower Roots, mostly arriving here in the autumn for spring flowering. Crocus, Colchicum, Cyclamen, Gladiolus, and several others, are not Bulbs, but Corms. The flowering season varies according to the different sorts of Bulbs. The majority may be lifted and kept tolerably dry during the resting period; but they wither and become exhausted if not replanted at the proper time, thereby causing many failures. Dutch Bulbs generally arrive in September, and the best results are obtained from those potted or planted at once, although some for succession may be kept in reserve up till the beginning of November. The failure in cultivating imported Liliums and other Bulbs may be often caused by their long-continued confinement in a dry atmosphere, whereby their vitality is often almost lost. The roots of some Bulbs are nearly always, more or less, in action, and these, especially, should not be kept out of the ground for any length of time.

BUNCHOSIA (from bunchos, the Arabic name for Coffee; in allusion to the similarity between the seeds of this genus and those of Coffee). ORD. Malpighiaceæ. Ornamental greenhouse evergreen shrubs, nearly allied to Malpighia, but having the racemes of flowers axillary. Fruit fleshy, indehiscent, externally smooth, and containing two or three seeds. They thrive best in a compost of loam, peat, leaf soil, and sand, in about equal proportions. Cuttings of ripened shoots will root in sand under a bell glass, in moist bottom heat, taking several weeks to do so. Good drainage is essential, both in striking cuttings and in the cultivation of the plants.

See Fig. 302, for which we are indebted to Messrs. Veitch and Sons. (B. M. 6403.)

BURCHARDIA (named after H. Burchard, M.D., a botanical author). ORD. Liliaceæ. An ornamental greenhouse herbaceous perennial, allied to Androcymbium. It thrives best in sandy peat, or peat mixed with a little loam. Propagated by offsets or divisions, made just previous to potting, in spring. It is best to repot annually. Good drainage should be allowed, and the plant must not be potted too firmly.

> B. umbellata (umbelled). fl. white, green. August. h. 2ft. New Holland, 1820.

BURCHCHELLIA (named after W. Burchell, a botanical traveller in the Cape of Good Hope, and in Brazil). ORD. Rubiaceæ. A stove evergreen shrub from the Cape of Good Hope. Flowers scarlet, disposed in heads at the tops of the branches, sessile upon a villous receptacle, intermixed with small distinct bracteoles; and each head is propped up by the ultimate pair of leaves; corolla of a clavate-funnel-shape. Leaves ovate, acute, a little cordate at the base, petiolate; stipules interpetiolar, broad, cuspidate at the apex, deciduous. It grows well in a rich light soil, or a mixture of turfy loam, turfy peat, and sand. Cuttings, not too ripe, root readily if planted in sand, and placed under a hand glass, in a gentle heat.

BURLINGTONIA (named after the "amiable and accomplished" Countess of Burlington). ORD. Orchideæ. A small genus of epiphytal orchids, all of which are beautiful and eminently well worth growing. They may be grown upon small blocks of wood, or in rustic baskets, suspended from the roof of the plant stove, where, if liberally treated with water, and a genial moisture in the air during the growing season, very little else will be required to ensure health and vigour. In the dull days of winter, they should be watered less frequently, but the plants must not be allowed to exhibit the slightest signs of distress from drought, or the consequences may be fatal to their health. When fastening these plants to blocks of wood, a little sphagnum should be used, for experience proves that they thrive best when their thin white roots can escape and hang exposed to the air. If growing them in baskets, it is preferable first to fasten them securely upon small pieces of bare cork, then to fill the basket, and finally to cover the whole thinly with a layer of sphagnum.

FIG. 303. FLOWER-SPIKE, PSEUDO-BULB, AND LEAF OF BURLINGTONIA DECORA.

Generally speaking, this genus is not a difficult one to cultivate; its great enemy is a small white scale, which secretes itself in the sheathing bases of the leaves. Here it rapidly multiplies, to the great detriment of the plants; the leaves soon turn yellow at the base, and drop off; the whole plant looks sickly, and soon dies, or else requires a very long time and much trouble to achieve its recovery to health. To prevent this, the bases of the leaves must be carefully looked into every time the plants are taken down to be dipped in water; and, should the slightest sign of this pest appear, a thorough washing with soft soap and tepid water must be given, repeating the operation every day until all traces of the insect are removed. Red thrip are also apt to work much mischief[225] with these plants. They take up their abode in the same way as the white scale, and if not speedily removed or destroyed, soon make sad havoc. To put a stop to the ravages of this pest, a wash should be given, as before recommended, and after the soap has been rinsed out of the base of the leaf, a little tobacco powder should be sprinkled into the hollows, and allowed to remain for a day or two before brushing it off. This process will, however, cause a somewhat dirty appearance, but it will ensure ultimate health and vigour. Propagated by dividing the plants.

> B. Batemanni (Bateman's).* fl. white, deliciously-scented; lip beautiful mauve. A very pretty South American species, resembling B. candida.

> B. candida (white).* fl. snowy-white, with a slight stain of yellow on the upper part of the lip, in substance and appearance like white satin, trimmed with gold; large, sweet-scented, in gracefully drooping three to four-blossomed racemes, produced from the axils of the leaves. April and May, lasting about three weeks in perfection, and sometimes having a second flowering season. l. one or two in number, dark green, and firm in texture. h. 1ft. Demerara, 1834. A very compact species, well suited for basket culture; it should never be allowed to get dry. It may be distinguished from other species by having a single row of tubercles, forming a ridge upon each side of the slightly hastate lip. (B. R. 1927.)

> B. decora (comely).* fl. white or rose-coloured, spotted with red; lip pure white; scapes erect, five to ten-flowered. Winter. Brazil, 1852. This species differs entirely from B. candida, inasmuch as it possesses a long slender-rooting stem, from different parts of which arise small oval pseudo-bulbs, each bearing a leaf; a lesser leaf appears at the base of a bulb, and from the axil of this the scape springs. It is a rather straggling but nevertheless beautiful species, and is best grown fastened upon long strips of cork, a little sphagnum being used in the operation; whilst, to prevent the plant getting too much "away from home," the young growths should be twisted back as they advance, and the practice continued until the pseudo-bulb is ultimately left near the centre, or in any spot which may appear bare. It likes strong heat and a very moist atmosphere, when growing; but during the period of rest, it should be kept cool and dry. See Fig. 303. (B. M. 4834.)

> B. d. picta (painted).* A beautiful variety, differing from the type in having shorter and more acute leaves; flowers produced in greater profusion, rose-coloured, beautifully mottled and blotched with dark purple. October. Brazil. (B. M. 5419.)

> B. fragrans (fragrant).* fl. very gratefully fragrant, disposed in erect racemes. April, remaining in perfection about three weeks. l. long, rigid, dark green. Habit compact. Brazil, 1850.

> B. pubescens (downy). fl., sepals and petals snow-white; distinguished by the somewhat hastate lip, which has three yellow ridges on each side, and also by the downy column. November. h. 6in. Brazil, 1850.

> B. rigida (rigid).* fl. purplish-white, spotted with pink on the lip; produced in heads. h. 1ft. Brazil, 1838. A handsome plant, but difficult to flower. (L. S. O. 36.)

> B. venusta (charming).* fl. white, slightly tinted with pink; produced in heavy pendulous clusters at various seasons of the year; lip stained with yellow. l. rigid, dark green. Brazil, 1840. It forms a compact mass, and requires less heat than the kinds previously described. It is often confounded with B. pubescens, from which it may be distinguished by its larger and more loosely arranged flowers, by its smooth column, by the lip not being hastate in shape, and by the numerous shallow ridges borne near the base upon each side. (L. S. O. 2.)

BUR MARIGOLD. See Bidens.

BURNET (Poterium Sanguisorba; from poterion, a cup; being used in cooling drinks). ORD. Rosaceæ. A native perennial. The leaves are sometimes used in soups, and with Borage in cooling drinks; they are also put in salads. The foliage only being useful, keep the flower-spikes removed, as this tends to increase the luxuriance of the plants. It thrives in any light soil. Propagated by division.

BURSARIA (from bursa, a pouch; the capsules very much resemble those of the Shepherd's Purse). ORD. Pittosporaceæ. A handsome, much-branched, greenhouse evergreen shrub, forming a very pretty object when covered all over with its elegant white blossoms. It thrives well in a compost of sandy loam and peat, in equal proportions. Young cuttings will root freely in sand, under a bell glass, with a little bottom heat.

> B. spinosa (thorny).* fl. white, small, disposed either in lateral or terminal panicles. July to December. l. small, oblong-cuneated, entire. h. 10ft. New Holland, 1793. (B. M. 1767.)

BURSERA (named after Joachim Burser, a disciple of Caspar Bauhin). ORD. Burseraceæ. Stove balsam-bearing trees. Flowers polygamous, or hermaphrodite; calyx small, four to six-toothed; petals four to six, spreading, generally valvate in æstivation; stamens eight to twelve; disk annular, with usually six to ten teeth; drupe oblong, covered by a three-valved succulent rind, containing three to five nuts. They thrive in a compost of loam and peat. Propagated by cuttings, placed under a glass, with bottom heat.

> B. gummifera (gum-bearing). fl. whitish, hexandrous; racemes terminal and axillary. l. deciduous, usually impari-pinnate; leaflets ovate, acute, membranous. h. 60ft. West Indies, 1690.

> B. serrata (serrate).* fl. whitish, decandrous; panicles axillary, shorter than the leaves. l. impari-pinnate, with three to five pairs of broad-lanceolate, bluntly-acuminated, serrulated leaflets; petioles and pedicels pubescent. h. 25ft. India, 1818.

BURSERACEÆ. An order of shrubs or trees, abounding in resinous juice; with opposite compound leaves, full of pellucid dots, and axillary and terminal fascicles of flowers. Fruit indehiscent, somewhat drupaceous. The genera best known are Amyris, Balsamodendron, Boswellia, Bursera, and Canarium.

BURTONIA (named after D. Burton, a plant collector for Kew Gardens). ORD. Leguminosæ. A genus of handsome greenhouse dwarf Heath-like shrubs, natives of West Australia. Flowers axillary, often thickly gathered at the ends of the branches; corollas rich purple; keel generally of a deeper colour, and the standard having sometimes a yellow blotch at its base. Leaves simple or trifoliolate, sessile, usually awl-shaped. They thrive well in a mixture of loam, peat, leaf soil, and sand, in equal proportions, with thorough drainage; but care must be taken not to give them too much water, as they require to be kept moderately dry, and are difficult to preserve in a living state. Young cuttings root freely in a pot of sandy soil, in a cool house, with a bell glass placed over them; but some of the species produce seed in abundance, which are the best means of increasing them.

> B. conferta (cluster-flowered).* fl. violet. July. l. simple, very much crowded, six to eight lines long, linear-subulate, with revolute margins, and are, as well as the branches, smooth. h. 2ft. 1830. (B. R. 1600.)

> B. minor (smaller). A synonym of Gompholobium minus.

> B. pulchella (beautiful). A synonym of B. scabra.

> B. scabra (rough).* fl. purple; peduncles axillary, bi-bracteate. April. l., leaflets glabrous, linear-mucronate. Branches puberulous. h. 2ft. 1846. SYN. B. pulchella. (B. M. 5000.)

BUTEA (commemorative of John, Earl of Bute, once a munificent patron of botany). ORD. Leguminosæ. A genus of very ornamental stove evergreen unarmed trees. Racemes many-flowered; flowers three together, on short pedicels, and furnished with two bracteoles each, under the calyx; corolla deep scarlet; down on the calyces usually black and velvety. Leaves pinnately-trifoliate; leaflets large, ovate, roundish, stipellate. For culture, &c., see Erythrina.

> B. frondosa (leafy). fl. 2in. long. l., leaflets roundish, obtuse, or emarginate, rather velvety beneath. Branches pubescent. h. 40ft. India, 1796. (B. F. S. 176.)

> B. superba (superb).* l., leaflets roundish, obtuse, velvety[226] beneath. Branches glabrous. Coromandel, 1798. This approaches the preceding species, from which it differs mainly by its scandent habit, and not by any botanical characters. (B. F. F. 143.)

BUTOMACEÆ. An order of aquatic plants, now usually included under Alismaceæ.

BUTOMUS (from bous, an ox, and temno, to cut; in reference to the sharp leaves, which injure the mouths of cattle that browze upon them). Flowering Rush. ORD. Alismaceæ. A very handsome hardy perennial aquatic, of extremely easy culture on the margins of ponds or muddy banks. Propagated by divisions of the roots, in spring.

BUXUS (from pyknos, dense; referring to the hardness of the wood). Box Tree. ORD. Euphorbiaceæ. A genus of hardy evergreen shrubs or small trees. Flowers unisexual, monœcious; male flowers, calyx of four minute segments, stamens four, inserted under the rudiment of a pistil; female flowers singly, at the tips of groups of male ones. Fruit, a regma, leathery, beaked with the styles. Leaves simple, opposite, exstipulate, evergreen. These well-known plants thrive in any light, well-drained soil. Seeds should be sown in similar situations as soon as ripe. Cuttings, made of the young shoots, from 4in. to 6in. in length, inserted in a shady place, in August or September, root readily. Layers of either young or old wood, made in autumn or early spring, will make good plants. They can also be increased by suckers and division.

> B. balearica (Balearic).* l. yellowish-green, oblong-elliptical, emarginate, coriaceous, about 2in. long, with a cartilaginous margin. h. 15ft. to 20ft. South Europe, 1780. This is a handsome species. The cuttings will require a shelter in winter, and in exposed situations it will be better to afford the plants protection.

> B. sempervirens (evergreen).* Common Box. l. oval-oblong, retuse, convex, coriaceous, shining; stalks slightly hairy. h. various. England. There are numerous forms of this popular shrub: argentea, silver-variegated; aurea has its leaves variegated with a golden colour; marginata has leaves with a golden margin; myrtifolia has small, oblong, narrowish leaves; obcordate-variegata is a variegated variety, with obcordate leaves, from Japan; suffruticosa is the form usually cultivated for edgings, its leaves are small, obovate, this is readily increased by divisions, and requires to be planted firmly, in order to keep it dwarf.

BYRSONIMA (from byrsa, a hide, and nimius, much used; because the bark of some of the species is used in tanning, in Brazil). ORD. Malpighiaceæ. Ornamental stove evergreen trees or shrubs. Flowers racemose, terminal, simple or branched. All the species thrive very well in any light soil, or a mixture of loam and peat. Cuttings made of half-ripened shoots will root freely in sand, under a hand glass, in a moist bottom heat.

> B. altissima (tallest).* fl. white; racemes clothed with rufous hairs. July. l. ovate-oblong, covered with rufous down beneath, but beset with bristles above, which are fixed by the centre. h. 60ft. Guiana, 1820.

> B. chrysophylla (golden-leaved).* fl. yellow; racemes simple. August. l. oblong, short, acuminated, acute at the base, rather wavy on the margin, and revolute, smooth above, clothed beneath with silky down, which is of a rusty golden colour. h. 14ft. South America, 1823.

> B. coriacea (leathery-leaved). fl. yellow, sweet-scented; racemes densely spiked, pubescent, erect. May. l. ovate, acute, quite entire and smooth. h. 30ft. Jamaica, 1814.

> B. verbascifolia (Verbascum-leaved). fl. yellow; racemes terminal. July. l. lanceolate-obovate, quite entire, downy on both surfaces. h. 6ft. Guiana, 1810.

BYSTROPOGON (from byo, to close, and pogon, a beard; in reference to the throat of the flower being closed up with hairs). ORD. Labiatæ. Greenhouse evergreen sub-shrubs, nearly allied to Mentha. Flowers small, in dichotomous, sub-corymbose, or panicled cymes; or else disposed in dense spicate whorls. Bracts lanceolate or subulate. This genus contains easily cultivated species, which are, however, of no value for garden purposes.

CABARET. The French name of Asarum europæum.

CABBAGE. The common name for Brassica; but especially applied to the plain-leaved hearting garden varieties of Brassica oleracea. To obtain good tender Cabbages in early spring and throughout the summer, it is necessary that they should be planted on rich, deeply-trenched ground, in a position free from the shade of fruit or other trees. Stable dung or good farmyard manure is best for this crop, and should be applied when trenching is being done, burying the manure a spit below the surface. Cabbages should not be planted successionally on the same ground, nor should they follow any of the other species of Brassica, if it can be avoided. A warmer position, not too much sheltered to make the plants tender, will be found beneficial for the earliest spring crop. This should not be planted too soon in autumn, as the plants are more subject to run to seed, especially if the winter be mild. The several forms of Cabbage are well known, being so[227] much cultivated by cottagers as well as gardeners. None of those forming close hearts will bear severe frost, but the Savoys are improved by a little in the early autumn. The Coleworts are very useful in winter, being perhaps the hardiest of all; and, as the hearts do not get so close and hard as the Savoy and other Cabbages, the frost, unless it is very severe, does not injure them so much.

Cultivation. The crop obtained in April and May is usually the most important one, young Cabbages being then much appreciated by everyone. The time for seed-sowing varies in different localities, from the third week in July to the middle of August. The first date would probably prove suitable for the northern parts of the country; and the latter would be early enough for the south. The seed should be sown thinly in beds of rather light, well pulverised soil, afterwards covering these with netting, to protect the seed from birds. The plants will be ready, in most cases, for placing out during September, or as soon as the ground can be cleared of other crops and prepared for their reception. The Early Battersea, or one of its many allied sorts, is best for sowing at this season; and, when planting out, an allowance of 2ft. apart each way will be sufficient. Seed should again be sown on a mild hotbed in February, and occasionally afterwards, for succession; and a second crop may be obtained from the plants put out in autumn if they are allowed to remain. Drumhead and other strong-growing sorts, sown in spring, will require from 6in. to 1ft. more space when planted out. These are not, however, of such good quality as the smaller-growing varieties.

Savoys. The seed of these should be sown in March or April, according to the locality, in the same way as described above, in seed beds; and the after treatment is also very similar. The young plants must not be allowed to starve in the seed bed, but should be kept watered, and planted out in June and July, choosing dull weather for the operation. The ground should occasionally be hoed between the plants, to keep the surface open and destroy weeds. Distances of from 15in. to 30in. between the plants, according to the variety, must be allowed. See Fig. 305.

FIG. 305. SAVOY CABBAGE.

Coleworts. Seed of these should be sown about the end of June, and planted out 1ft. apart on a sheltered border, when large enough. Rosette is one of the best varieties; but the early Cabbages are often grown and used as Coleworts before they have had time to form close hearts.

FIG. 306. EARLY YORK CABBAGE.

Pickling Cabbage. The Red Dutch is the variety generally grown for pickling, and is probably the best to keep its colour when so treated. Seed should be sown in August, to stand the winter, and again in February for a succession; only a few plants will, in the majority of cases, be required, as, if liberally treated, they grow to a good size.

FIG. 307. OXHEART CABBAGE.

Sorts of White Cabbage. These are extremely numerous, and selections or improved forms are of annual appearance. Some of the old types are, however, still much cultivated. The following are a selection of the best sorts for general purposes: Atkins' Matchless, Carter's Heartwell, Early Battersea, Early York (see Fig. 306), Ellam's Early Dwarf, Enfield Market, Little Pixie, Oxheart (see Fig. 307), St. John's Day (see Fig. 308), Sugarloaf, Wheeler's Imperial, and Portugal or Couve Tronchuda. The last-named variety was introduced from Portugal some years ago, where it is[228] much grown. It has a large midrib, and does not form very close hearts. It is very tender when cooked, and is only suitable for culture in summer. Under the name of Gilbert's Cabbage Broccoli, or Chou de Burghley, a variety of Cabbage was recently distributed which produces, if left long enough, hearts resembling Broccoli. Although there are different opinions as to its merits, it is said to be very tender when cooked, and is considered a decided acquisition.

Of Savoys, the best are: Drumhead, Dwarf Green Curled, Early Ulm, Large Late Green, and Tom Thumb.

FIG. 308. ST. JOHN'S DAY CABBAGE.

Insects, &c. The majority of the Cabbage tribe is attacked by a very large number of different caterpillars and other pests, both above and below ground. The plants in their young stages are always a prey for snails and slugs, and often require a dusting of soot and lime as a protection. When planting out, many of the plants are often found with a protuberance at the root, caused by an insect, and termed "clubbing." Those so injured should be thrown away if they can possibly be spared, and the others dipped in a thick solution of soot water. This is the worst kind of disease the Cabbage tribe is subject to. The caterpillars of several moths and butterflies are very destructive in summer, often eating through the hearts of Cabbages and Cauliflowers, and so rendering them totally unfit for use. Hand-picking, or dusting with lime, is apparently the only means of diminishing the numbers of these pests.

CABBAGE CATERPILLARS. Large Cabbage White (Pieris brassicæ). From May to July, and again in September and October, this, the most common of our butterflies, may be seen in great numbers, frequenting gardens, lanes, and fields, being especially numerous where Cabbages are growing. Their beautiful yellow eggs are laid singly on the under surface of the leaves, and securely fastened by a natural glue; from these, in due time, issue the small, but destructive, "green caterpillars." Shortly after birth, they become quite green in front and yellow behind. They then get hairy and dotted over with black; they have eight pairs of feet, of which the three front ones only are "true" legs, or those which ultimately develop into the legs of the butterfly. They change their skin several times, and at each moult become larger in size. When full grown, they are about 1½in. long, of a light green or bluish hue above, and yellow beneath; along the back of the adult caterpillar is a conspicuous yellow line, edged on each side with black dots.

FIG. 309. CATERPILLAR AND CHRYSALIS OF LARGE CABBAGE BUTTERFLY.

The chrysalis, or pupa, is commonly found on window-ledges, palings, walls, and similar places; but is sometimes attached to the plant (see Fig. 309). It is a rather curious object, of the colour of stone, and prettily chiselled. It is fastened to the plant by the tail and by a belt of silk round the middle.

FIG. 310. LARGE WHITE CABBAGE BUTTERFLY.

FIG. 311. SMALL WHITE CABBAGE BUTTERFLY AND CATERPILLAR.

The perfect male insect has the body black and wings white on the upper side, except the tips of the fore-wings, which are black and crescent-shaped; and on the upper edge of the hinder wings there is a black spot. On the under side, the fore wings are white with yellow tips, and two black patches on each; the hind wings are yellow, with small black markings. The antennæ are alternately black and yellow, with the club black above and yellow beneath. The female (see Fig. 310) differs[229] from the male in having two large black spots on each of the fore or upper wings, and a spot on the inner margin.

The Small White (Pieris rapæ, see Fig. 311) has two broods in the year, the first batch about April, and the second in July. The eggs are always placed on the upper side of the leaf, and are hatched in from ten to thirteen days, the caterpillars becoming full grown in about three weeks after emerging. The colour of the caterpillar is dark green, with a fine line of yellow, and a row of yellow spots down the sides. The chrysalis is attached by the tail and a band of silk to the place selected by the caterpillar, and varies greatly in colour, although generally it is of a whitish-brown.

Cabbage Moth (Mamestra brassicæ). Newman, in his "British Moths," thus describes the Cabbage Moth: "The antennæ are rather long and slender, and scarcely ciliated in either sex; the fore-wings are dark, smoky, grey brown, mottled and marbled with confused markings, both darker and paler; the orbicular spot is inconspicuous, but decidedly to be traced; the reniform stigma is delicately outlined with white or whitish-grey, and has a pale anterior disc, in which the same pale grey colour predominates; the hind wings are dark, smoky brown with rather pale base, and rather darker crescentic discoidal spot and wing-rays; the head, thorax, and body have the same colour as the fore and hind wings." The eggs are laid on Cabbages, or similar plants, and are hatched in a few days. The caterpillars are very voracious, feeding by day and night, and, what is worse, they spoil with their excrement, in the case of Cabbages, more than they eat. They are of a dark colour, with a kind of marbling, more or less distinct, on the back, the effect being produced by a triangular mark containing two white dots on each of their segments. On being disturbed, they roll themselves into a tight ring, and so remain until they suppose that danger is over. They descend into the earth for change to smooth red-brown chrysalids, and remain there till the following spring. If the chrysalids were collected and destroyed during the autumn and winter digging, much injury would be obviated through the succeeding spring and summer.

The destruction of these pests is a very troublesome matter, as the grubs of the last-named kind bore into the heart of the cabbage. Hand-picking is the only sure method. Anything emitting a distasteful odour will also keep them at bay. Miss Ormerod recommends throwing gas-lime over the plants, but it must be previously weakened by a few months' exposure. The following remedy may also be recommended:

Paraffin, or Coal Oil. Mix one ounce of oil with a gallon of soapsuds, and water the plants with the mixture before the caterpillars appear. If any have appeared, an application at the rate of two ounces to the gallon will generally clear them off. Of course, this operation must not be performed less than a month previous to cutting the cabbages, on account of the smell. Soapsuds alone will also clear caterpillars from most smooth-leaved subjects if frequently applied.

CABBAGE FLY (Anthomyia brassicæ). Among the injurious insects which infest Cabbages, none commit greater havoc to both stem and root, than the maggots of the Cabbage Fly. "They are whitish, cylindrical, and legless, tapering to the head, and blunt at the tail, which has short teeth on the lower margin, and two brown tubercles in the middle. When full grown, they are about ⅓in. long. They then leave the plants, and turn, in the earth, to pupæ, with a few black spots at the head, and short teeth at the tail, inside which the flies form, and emerge in about a fortnight or three weeks. The fly is of an ashen-grey colour, and smaller than the Onion Fly, which it much resembles. The male is of a darker grey, and has a short black stripe along the back between the wings, with a curved one on each side of it, and one black stripe along the abdomen" (Ormerod). The presence of these maggots may be easily detected by the flagging and change of colour of the leaves. The infested plants should be immediately removed and destroyed. The following remedy will be found beneficial:

Lime. Hot lime should be soaked in water for about twenty-four hours. When clear, the infested Cabbages should be well washed with the liquid. Superphosphate of lime may also be applied with advantage.

CABBAGE GALL WEEVIL (Ceutorrhynchus sulcicollis). This is a pretty little beetle, about three-quarters of a line or one line in length. Its colour is dark, but the insect is really of a coppery hue; on the thorax and head are rather large depressions; the wing-cases vary in colour from green to greenish-blue, or even black, and along the entire length of the elytra are parallel lines or holes, as may be seen with the aid of an ordinary lens. This insect, which causes much damage to plants of the Brassica family, is, in some places, very difficult to eradicate. It is also very destructive to other crops, and, therefore, any effectual remedy is valuable. The following methods may be recommended:

Carbolic Acid. Mix 1oz. Calvert's No. 5 carbolic acid with two gallons of soapsuds, and add sufficient loam or clay to make a thin paste. Dip the roots of the whole of the plants into this before they are set out. Well stir the mixture, and put the plants out in a damp soil, so that watering will not be necessary.

Paraffin, or Coal Oil. This, applied in the same manner as recommended for Carbolic Acid, is also very good.

Guano, Superphosphate of Lime, and Nitrate of Soda. A good dressing of either of these, given after the ground is dug, and in wet weather, about a month before the plants are put out, has been found very beneficial; but, although preventatives, they do not totally clear the crop from insects for the season.

Soot and Lime. Take equal parts of air-slaked lime and soot, and mix together. Set the plants with a trowel, and, having placed some soil over the roots, throw in a little of the mixture, filling up the hole with soil.

CABBAGE MOTH. See Cabbage Caterpillars.

CABBAGE PALM. See Euterpe oleracea.

CABBAGE POWDERED-WING (Aleyrodes brassicæ). A small four-winged powdery fly, closely allied to the Aphides. As implied by its name, this pest infests the various sorts of Cabbages. It is more particularly prevalent in autumn. Its presence may be readily detected by the partial discoloration of the leaves attacked. The head and body between the wings are black, with yellow variegation; abdomen yellow or rosy; wings white and mealy (whence its common name), the upper pair each having a darker spot, near the centre. Its destructive power resides in the rostrum, or sucking-tube, with which its head is furnished.

Remedies. The only effectual means of exterminating this pest is to destroy the leaves, preferably by burning. If its presence is detected early, an application of tobacco water, or diluted soft soap, may prove beneficial.

CACTEÆ. A large order of succulent plants, with remarkable spines clustered on the cylindrical, angular, two-edged, or leafy stems. Flowers very variable, showy or minute, usually solitary, sessile, rarely in fascicles, ephemeral; petals disposed in two or more series, hardly distinguishable from the inner sepals, and sometimes united with them; sepals numerous, united and adnate a great length to the ovarium. Fruit fleshy, one-celled, many-seeded. Well-known genera are Cereus, Melocactus, Mammillaria, Opuntia, Pereskia, and Rhipsalis.

CACTUS (from kaktos, a name used by Theophrastus to describe a spiny plant). This generic term is popularly applied to all members of the extensive family Cacteæ, which order may be distinguished by the following characteristics: Calyx composed of many sepals, usually indefinite in number, the inner series not readily distinguishable from the petals, united and adnate a great length to the ovary; with the tube smooth in the genera Mammillaria, Melocactus, and Rhipsalis; or with the lobes of the sepals crowning the fruit, and having the tube scaly, as in the genera Cereus, Opuntia, and Pereskia. Petals disposed in two or more series, hardly distinguishable from the inner sepals, and somewhat united to them; sometimes irregular, and disposed in a long tube at the base, but distinct at the apex, as in the genera Mammillaria, Melocactus, and Cereus; sometimes equal and distinct to the very base, forming a rotate corolla, as in the genera Opuntia, Pereskia, and Rhipsalis. Stamens indefinite, disposed in many series, more or less cohering with the petals or inner sepals; filaments slender, filiform; anthers ovate, versatile, two-celled. Ovarium obovate, fleshy, one-celled. Fruit fleshy, one-celled, many seeded, either smooth and crowned by the calyx, or covered with scales, scars, or tubercles, and umbilicate at the apex. This order contains fleshy or succulent shrubs, very variable in habit and size. Flowers very variable, showy, or minute, usually solitary, sessile, rarely in fascicles, ephemeral, expanding by night or day. Leaves usually wanting, but, when present, small, caducous, and terete, rarely flat and expanded, sometimes alternate and disposed in a spiral order, always glabrous and fleshy. Prickles or bristles disposed in fascicles, rising from the axils of the leaves. In the leafless genera, the fascicles of spines are disposed on the angles of the stem, rising from tubercles. Stems usually angular, winged, or regularly beset with tubercles, rarely terete, usually jointed; joints compressed. A group of Cacti is shown at Fig. 312, for which we are indebted to Herr Fr. Ad. Haage, jun., of Erfurt, Germany. See Cereus, Disocactus, Echinocactus, Epiphyllum, Leuchtenbergia, Mammillaria, Melocactus, Nopalea, Opuntia, Pelecyphora, Pereskia, Phyllocactus, and Rhipsalis.

Cultivation. Perhaps no class of plants more easily accommodate themselves to a general system of treatment, than do these; although certain genera would undoubtedly thrive better than when subjected to the lower temperature, suited to the requirements of those coming from cooler regions. Notwithstanding that nearly all the species are natives of the western hemisphere, they occur in various geographical and altitudinal areas, in which the temperature is proportionately lessened or increased, as the case may be; yet, presuming a special house is set apart for their culture, the majority of the species may be happily suited therein. The warmest end of the structure should be selected for the tropical kinds; while those found in cooler regions may be grown in the other portions of the house; even those which are hardy in our climate are really best wintered in a house or frame. Granted that several species will endure our winter outside, it is yet necessary to give them the shelter of a friendly ledge of the rockery, or frame, or to cover them in their permanent position with a hand light, or sheet of glass, in order to prevent the ill-effects of excessive moisture. Generally, a winter temperature of from 50deg. to 55deg., and a summer one of from 70deg. to 80deg. during shade, or in sunshine up to 90deg., will be found advantageous. When thus treated, it will be necessary to keep the tropical species, on the whole, very dry during the winter. As regards soil, potting, and general treatment, all may be treated alike, except Epiphyllum, Disocactus, and Pereskia (which see). Some growers give them the protection of a house in winter, and stand them outside during the summer, which is not, however, a very commendable plan, as, in consequence of the very variable character of our climate being especially prejudicial to several of the tender and more delicate species, the often excessive amount of moisture they would receive, will produce a weakly state of health in many, while others will be lost. It is far better if their culture is attempted at all, to give them the proper treatment. The numerous species and varieties found on the Rocky Mountains are a most interesting series, and may be well managed in a cold frame facing south, arranging them on shelves as close to the glass as possible, and keeping them very dry through the winter. If the weather is very severe, the lights should be matted. One of the best collections of these in the country, is in the possession of E. G. Loder, Esq., Floore House, Weedon, Northampton, where a great number are admirably grown in frames, and under a large ledge of the rockery outside. Amateurs may grow quantities of handsome Cacti either in dwelling rooms near the window, or in small frames or greenhouses. As they are slow growing, not much space will be occupied; at the same time, a great deal of interest will be centred in their culture. As regards watering and insect pests, they are but little trouble. Miniature Cacti, of numerous kinds, are now often sold in small pots, and most attractive little subjects they prove.

[See larger version]

Soil, Drainage, and Potting. Good ordinary fibrous loam should form about one-half of the compost, the other half should be made up of sand, broken bricks, and lime rubbish in equal quantities; the whole to be carefully mixed together, and not used until it is moderately dry. It is[231] absolutely necessary to ensure perfect drainage; a good "stopper" should, therefore, be placed over the hole at the bottom of the pot, and about one-third of its depth filled with draining material. The best time for potting is during February and March. Turn out the plants, and remove nearly all the old soil from the roots, taking away any dead or decaying roots which may be observable. Place some of the roughest soil next the crocks, and gradually fill the pots with the finer material, well working the same amongst the roots; finally press the soil moderately firm. Do not water for a few days after potting, but syringe every evening, especially if the weather be fine; a little extra heat may be given after potting, to excite new, healthy growth. It will not be necessary every year to repot specimens in large vessels. A good top-dressing, with an occasional dose of weak liquid manure, is all they will require for several seasons.

Watering. This must be discriminately managed, especially during the winter; for, whatever their treatment as regards temperature during that season, they must be studiously watered, and anything like a saturated condition of the soil should be avoided. If the temperature is brisk, a little water may be given once a week, or perhaps not quite so often. If the plants are subjected to very cool treatment, water must be sparingly administered during November, December, and January; after which, they should be examined weekly, and very carefully attended to. During the summer months, when in active[232] growth, they will not suffer if watered twice a week; and, on bright afternoons, light syringings may be advantageously given.

Propagation. Three methods are adopted, viz., by cuttings or offsets, grafting, and seeds; the former is the plan generally adopted. The cuttings or offsets should be removed with a sharp cut, and laid upon a sunny shelf until the wound is healed and roots are emitted, when they should be potted in sandy soil, and placed with the others. They will thrive freely if kept syringed. Grafting is resorted to with delicate kinds, which, from some reason or another, will not grow freely except upon the stock of a stronger species; and, by this means also, such delicate kinds can be kept from the damp soil, which frequently causes incipient decay. The stocks usually employed are those of Cereus tortuosus, C. peruvianus, &c., according to the species intended for working; they readily unite with each other. If the scion and stock are both slender, wedge-grafting should be adopted; if both are broad, it is best to make horizontal sections, placing them together and securing in proper position by tying with matting, but not too tightly, or the surface may be injured. Propagation by seeds is not often adopted, as it is a very slow method; they should be sown in very sandy soil, and placed in a semi-shady position until germination commences, when they may be exposed, and very carefully watered.

CALABASH-TREE. See Crescentia Cujete.

CALABA-TREE. See Calophyllum Calaba.

CALADENIA (from kalos, beautiful, and aden, a gland; in reference to the disk of the labellum being finely beset with glands). ORD. Orchideæ. A genus of pretty greenhouse terrestrial orchids from New Zealand and Australia. They should be kept in a cool frame or greenhouse, and carefully watered, when not in a growing state. A compost of peat, loam, and sand, in equal parts, suits them well. Over thirty species are enumerated, but probably none are seen out of botanic gardens.

CALADIUM (derivation of name doubtful; probably of Indian origin). ORD. Aroideæ. Stove perennials, chiefly grown for the great beauty and varied hue of their leaves. Spathe hood-like, rolled round at the base; spadix, upper portion entirely covered with stamens, but ultimately becoming bare at the extreme top, provided with blunt glands or sterile stamens in the middle, and ovaries beneath; anthers shield-shaped and one-celled; ovaries numerous, two-celled, with from two to four ascending ovules in each cell. Leaves upon long petioles, more or less sagittate, ovate, and usually very richly coloured. Fruit a one or two-celled berry, with few seeds. They are all of easy culture, and grow freely in a humid atmosphere. In March, when the tubers have been kept dry or rested for some time, they may be started into growth again, in small pots, placed in a stove or pit, where a night temperature of from 60deg. to 65deg. is maintained, and syringed daily once or twice at least. As soon as indications of activity are presented, they may be shifted into 4in., 5in., or 6in. pots, or larger ones may be used if good sized specimens are required. If the tubers should be in large pots, it is best to turn them out, dividing if necessary, and placing all the crowns in small pots, from which they can be removed when root action and growth are resumed, and they require more room. Large tubers, if sound, may be divided, and the pieces placed in pots of such sizes as it is desired to grow them in.

Soil. Turfy loam, leaf mould, turfy peat, and a little well decomposed manure, in equal parts (not broken up too fine), with a good sprinkling of sharp sand, form an excellent compost, the whole being well incorporated together. Thorough drainage must be insured, as these plants require an abundance of water. After potting, they should be placed in a stove temperature, and kept well moistened by syringing two or three times daily. If accommodated with mild bottom heat at this time, they will make much[233] freer and more vigorous growth than if otherwise treated. Water sparingly at first, but as soon as the leaves expand, increase the supply; and, when the pots are well filled with roots, apply clear liquid manure at every other time of watering. As the season advances, the temperature and humidity of the house should be increased. During bright sunshine, Caladiums should be slightly shaded for a few hours in the middle of the day, with some thin material, just to break the fierceness of the sun's rays; but the more they are exposed to the light at other times during growth, the brighter, richer, and more beautiful will the foliage be. As soon as the plants have attained a good size, some of them should be placed in the coolest part of the house, and partially hardened off; they may then be taken to the conservatory, allowing them a situation free from currents of cold air, and giving water only when really necessary. They may remain here for some time, but care must be taken to return them to the stove before they suffer from cold.

Small neatly grown specimens make beautiful ornaments for table decoration, and their suitability for exhibition purposes is well known, and largely taken advantage of. Towards autumn, and as the foliage begins to fade, the supply of water should be gradually lessened, until all the leaves die down; the pots should then be placed under the stage in the stove, where they can be looked to now and then, and a little water given if required. By no means allow the tubers to get dried up, as is often done; for, if so, they will frequently rot away inside; whereas, kept in a semi-moist condition, even the most delicate can be preserved. In this state, they may remain until the following season. Caladiums will not endure a very low temperature; from 55deg. to 60deg. is as low as they can be safely kept. Very few of those known as "true species" are grown, being superseded, for general decorative purposes, by the numerous hybrids which have been raised of late, principally from C. bicolor.

FIG. 315. CALANDRINIA MENZIESII, showing Flower and Habit.

CALANDRINIA (in honour of L. Calandrini, an Italian botanist, who lived in the beginning of the eighteenth century). ORD. Portulaceæ. A rather large genus of fleshy, glabrous, annual or perennial, herbaceous plants, some fourteen or fifteen species growing in Australia, the rest occurring in the New World. Flowers usually rose or purple, solitary, or in terminal umbels or racemes. Leaves quite entire, radical or alternate. Only four or five species are cultivated in this country; these are treated as half-hardy annuals—with the exception of C. umbellata, which is best treated as a biennial—and as such they are extensively grown in small gardens, with most satisfactory results. They should be sown in the spots where they are intended to flower, as transplantation, unless performed with more than ordinary care, will considerably check their growth or result in loss. Their flowers only expand during bright sunshine, and, consequently, they are less grown than they otherwise would be. The plants thrive in[236] a light sandy soil. C. umbellata may be sown in a pan, placed in a cold frame, in May or June; and when the plants are large enough to handle, they should be potted off, or placed out in colonies where they are to bloom.

> C. discolor (two-coloured). fl. bright rose, with a yellow tuft of stamens in the centre, 1½in. across; raceme long. July, August. l. fleshy, obovate, attenuated at the base, pale green above, purple beneath. h. 1ft. to 1½ft. Chili, 1834. (B. M. 3357.)

> C. grandiflora (large.flowered).* fl. rosy, about 2in. across; calyx spotted; raceme simple, loose. Summer. l. fleshy, rhomboid, acute, petiolate. Stem suffruticose. h. 1ft. Chili, 1826. (B. R. 1194.)

> C. Menziesii (Menzies').* FL. deep purple-crimson, from ½in. to 1in. across, terminal and axillary, solitary. June to September. l. elongated, spathulate, much attenuated at the base. Stems much branched, prostrate. California, 1831. SYN. C. speciosa. See Fig. 315. (B. R. 1598.)

> C. nitida (shining). fl. rose-coloured, about 2in. across; raceme leafy, many-flowered. Summer. l. oblong-spathulate, sub-acute, glabrous, attenuated at the base, 1in. to 2in. in length. h. 6in. Chili, 1837. A very pretty hardy annual, forming a tuft from 4in. to 6in. across.

> C. speciosa (showy). A synonym of C. Menziesii.

FIG. 316. CALANDRINIA UMBELLATA, showing Flower and Habit.

> C. umbellata (umbellate).* fl. of a dazzling magenta-crimson, about as large as a sixpence; corymb cymose, terminal, many-flowered. Summer. l. radical, linear, acute, pilose. h. 6in. Peru, 1826. A very charming half-hardy biennial. See Fig. 316. (P. M. B. 12, 271.)

Other species occasionally met with are: compressa, micrantha, and procumbens; they are, however, inferior to those described above.

CALANTHE (from kalos, beautiful, and anthos, a flower). ORD. Orchideæ. SEC. Vandæ. A very handsome genus of stove terrestrial orchids. They may be characterised as robust-growing plants, producing large, broad, many-ribbed, or plaited leaves, which are, with one or two exceptions, evergreen, and long spikes, bearing many flowers, distinguished by their calcarate lip, which is attached to the column, and by the eight thick, waxy pollen masses adhering to a separate gland. Calanthes should be special favourites with amateurs, as, in the first place, they produce an abundance of showy flowers, which last a long time in perfection; and, secondly, because they are so easily managed. In potting these plants, it will be necessary to depart from the usual style of potting orchids, and, instead of elevating them above the rim of the pot upon a cone of peat and sphagnum, they must be kept below the rim, as in potting ordinary plants. In place of the usual soil and moss, these plants should have a mixture of loam, leaf mould, and peat, broken up rough, to which may be added some silver sand and dried cow manure. During the growing season, they require abundant supply of water, and in winter even this element must be administered freely to the evergreen kinds; whilst the deciduous ones, on the contrary, enjoy a thorough rest after blooming. Good drainage is essential to all. Little more need be said upon the cultivation of Calanthes during the summer months. When growing, they enjoy strong heat and plenty of moisture; but, when growth is complete, a cooler situation is most beneficial. They are subject to the attacks of various insects, which must be continually searched for, and, when found, destroyed; for, if neglected in this particular, the bold and handsome leaves will be much disfigured, and rendered far from ornamental. Propagated by suckers and divisions. About forty species are known, of which the following are a selection:

> C. curculigoides (Curculigo-like). fl. beautiful orange-yellow, disposed in an erect spike. Summer and autumn. l. large, evergreen, plaited. h. 2ft. Malacca, 1844. (B. R. 33, 8.)

> C. Dominyi (Dominy's).* fl., sepals and petals lilac; lip deep purple. This fine hybrid is a cross between C. Masuca and C. veratrifolia. (B. M. 5042.)

> C. furcata (forked). fl. creamy white, very freely produced; spikes erect, 3ft. long. June to August. Luzon Isles, 1836. An excellent exhibition plant.

> C. Masuca (Masuca).* fl., sepals and petals deep violet colour, with an intense violet-purple lip; numerously produced on spikes 2ft. long. June to August. India, 1838. (B. M. 4541). The variety grandiflora differs from the type in its greater size both of spike and individual flower; the gigantic spikes are from 3ft. to 4ft. high, and continue blooming for three months.

> C. Petri (Peter Veitch's).* fl. whitish-yellow. Said to be very like C. veratrifolia, but bearing leaves a little narrower, and a system of five curious sulcate yellowish calli on the base of the lip, without the single lamella and teeth which are proper to that species. Polynesia, 1880.

> C. pleiochroma (many-coloured). fl. whitish, purplish, ochre, orange. Japan, 1871.

> C. Regnieri (Regnier's). fl., sepals and petals white; lip rosy-pink; middle lobe short, wedge-shaped, and emarginate. Pseudo-bulbs jointed, Cochin China. fausta is a fine variety, with the base of the tip and column a warm crimson.

> C. Sieboldii (Siebold's).* fl. yellow, large; spikes erect. l. broad, dark green, plaited. h. 1ft. Japan, 1837. An elegant evergreen dwarf-growing species. (R. H. 1855, 20.)

> C. Textori (Textor's). fl. cream-white, washed with violet on the petals and column, as well as on the base of lip, where the calli are brick-red, changing later on to ochre-colour, excepting the white-lilac base of sepals and petals and the column; lip very narrow. Japan, 1877.

FIG. 317. SINGLE FLOWER OF CALANTHE VEITCHII.

> C. Veitchii (Veitch's).* fl. rich bright rose, with a white throat; spikes often attaining a height of 3ft., and bearing an immense quantity of flowers.

(B. M. 5375.)

> C. veratrifolia (Veratrum-leaved).* fl. pure white, except the green tips of the sepals and the golden papillæ on the disk of the labellum; spikes 2ft. to 3ft. high, freely produced on well-grown plants. May to July. l. 2ft. or more long, dark green, broad, many-ribbed, with wavy margins. India, 1819. See Fig. 318. (B. M. 2615.)

[237]

FIG. 318. SINGLE FLOWER OF CALANTHE VERATRIFOLIA.

> C. vestita (clothed).* fl., sepals and petals pure white, numerously produced in a many-flowered, nodding spike. l. deciduous. Pseudo-bulbs large, whitish, h. 2½ft. Burmah. (B. M. 4671.) The varieties of this species are very numerous.

> C. v. igneo-oculata (fire-eyed).* fl., base of the column purplish, over which is a dazzling fire-colour, the blotch in the base of the lip of the same colour. Borneo, 1876.

> C. v. nivalis (snowy).* fl. pure white, entirely destitute of any colour on the lip. Java, 1868.

> C. v. rubro-oculata (red-eyed).* fl. delicate white, with a blotch of rich crimson in the centre; upwards of 2in. across; spikes long, drooping, having a white downy covering, and rising from the base of the silvery-green pseudo-bulbs, when the latter are without leaves. October to February.

> C. v. Turneri (Turner's).* fl. pure white, with rose-coloured eye, larger, and produced on longer flower-spikes than the other kinds; form of flowers more compact. Java. This is considered by some authorities, to be a distinct species.

CALATHEA (from kalathos, a basket; in reference to the basket-shaped stigma, or to the leaves being worked into baskets in South America). ORD. Scitamineæ. This genus of very ornamental-leaved stove plants is distinguished from Maranta by mere botanical characters; and the two genera are often confounded. Flowers in terminal spikes, bracteate; perianth six-cleft, outer segments lanceolate, inner ones blunt and irregular; stamens three, petal-like. Leaves large, springing from the contracted stem, near the root. They delight in a rich, loose, open soil, consisting of peat, loam, and leaf soil, in about equal proportions, with the addition of a good sprinkling of sand, to keep it open and porous. The mixture should be used in a rough, lumpy state, so that the roots, which are of large size, may be able to travel with freedom. Nearly all the species admit of easy increase by division. July is a favourable time to set about it, or it may be carried out any time between that and the spring months. In order to make the necessary separation without damaging the roots, the plants should be shaken out from the soil, when they may be divided into as many pieces as there are separate crowns. Whether an increased stock be desired or not, Calatheas require fresh soil annually; and, if not reduced by division, they become much too thickly foliaged to properly develop, unless they are shifted into larger-sized pots, which can always be done if large specimens are required. When making divisions, see that each crown is well furnished with roots, so that they may at once commence sending up fresh young foliage. Although Calatheas require an abundant supply of water while growing, a stagnant moisture is most injurious; good drainage is, therefore, essential. To have the leaves in fine, healthy condition, plenty of atmospheric moisture must be maintained during their growth; and, if syringing is resorted to for the purpose of securing this, clear soft water should be used, or an unsightly deposit will be the result, by which the beauty of the plants, unless they are frequently sponged, will be spoiled. These plants require, in addition to plenty of moisture, moderate shade during the summer, as they dislike strong sunshine, and may, therefore, be grown among ferns, under creepers, in situations that would be of little use for other purposes. Calatheas are not subject to insects if properly supplied with water while growing, and a sufficiently moist atmosphere is at all times maintained; but, if either of these are lacking, red spider soon put in an appearance, and quickly disfigure the leaves.

CALATHIAN VIOLET. See Gentiana Pneumonanthe.

CALCARATE. Spurred, or having a spur.

CALCEOLARIA (from calceolus, a little slipper, in allusion to the form of the corolla; the form calceolarius, shoemaker, probably chosen to include a reference to F. Calceolari, an Italian botanist of the sixteenth century). Slipperwort. ORD. Scrophularineæ. A genus of hardy or half-hardy shrubs, sub-shrubs or herbs. Peduncles one or many-flowered, axillary or terminal, corymbose; corolla with a very short tube; limb bilabiate; upper lip short, truncately rounded, entire; lower lip large, concave, slipper-shaped. Leaves opposite, sometimes three in a whorl, rarely alternate.

SHRUBBY SECTION. In addition to the widely-known utility of this class for bedding purposes, they are fine decorative plants when well grown, and useful alike in conservatory or dwelling house. It will be found more convenient to grow these in a pit or frame, as in such places they are less liable to the attacks of fly, and make sturdier growth. If large plants are required, cuttings should be taken in August, placed in a cold frame facing[239] the north, in sandy soil, and, when rooted, potted off into 3in. pots. They should then be placed in a light sunny frame, where they may remain until the middle of February. The points should then be pinched out. When the plants break, they must be shifted into 48-sized pots. If there are from four to six breaks to each plant, it will be sufficient; but, should such not be the case, the plants must be stopped again, when the requisite number will probably be obtained. Directly the roots touch the pots, the plants should be transferred to 7in. or 8in. pots, in which they will flower, and the shoots must be tied out so as to develop fully. Every effort should be exerted to keep the foliage green to the base of the plants, and they should be fumigated on the first appearance of green fly. As the flower-spikes are thrown up, weak liquid manure, applied two or three times a week, will prove beneficial. For potting, the following compost is most suitable: One-half good fibrous loam, one-eighth thoroughly rotted manure, and the remainder leaf soil, with enough sharp sand to keep the whole open. During frosty weather, of course, it will be necessary to protect the frames with mats, and to water judiciously, to avoid damping. Those plants intended for bedding will not require to be repotted, but should be inserted, about 3in. apart, in sandy soil, in a cold frame. The tops must be taken off early in March; and from the middle of April to the middle of May, they may be planted out where they are to remain. Should frosty weather, accompanied by drying winds, ensue, the plants will require the protection of inverted flower-pots, with pieces of slate or crock placed over the holes. A good soil, abundantly enriched with rotten manure, is most desirable for them.

FIG. 321. HERBACEOUS CALCEOLARIA.

Varieties. These are very numerous. The best of them are the following: BIJOU, dark red, very free; GAINE'S YELLOW, rich deep yellow, extremely free; GENERAL HAVELOCK, crimson-scarlet, very fine; GOLDEN GEM, bright yellow, perhaps the best; SPARKLER, crimson-gold, dwarf; VICTORIA, dark maroon, very attractive.

HERBACEOUS SECTION. These, like the preceding, are very useful, both for house and conservatory decoration (see Fig. 321). A packet of seed from a first-class firm will, if properly managed, produce a good percentage of excellent flowers. The seed may be sown from June to August, when large batches are required (when only one sowing is made, July will be the best month), on pans of light, sandy soil, which should be soaked with water before sowing. Care must be taken to make the surface of the soil level, and also to sow the seed as evenly as possible. It is better not to cover with soil, but a sheet of glass should be laid over the pan, which must be placed in a shady part of the greenhouse or cold frame until the young plants show the first leaf. The glass can then be gradually removed. When large enough to handle, the seedlings must be pricked out, about 2in. asunder, in pans or boxes, and placed in a close, shaded situation. As soon as of sufficient size, they must be placed singly in 3in. pots, returned to the frame, kept close for a few days, and as near the glass as possible, to make them sturdy. When necessary, they should be shifted into 5in. pots, in which they may be kept through the winter; or the later batches may be placed in small pots. By the end of October or early in November, the plants will be strong and fit for wintering; at this stage, the best place for them is in a dry, frost-proof pit, or on an airy shelf of the greenhouse, giving them sufficient water to prevent flagging. All dead leaves must be removed. On the first appearance of green fly, the plants should be fumigated with tobacco. From the end of January onwards, in order to encourage growth, the plants should be removed into 7in. or 8in. pots, giving plenty of drainage, and a compost consisting of one-half good light fibrous loam, one-fourth thoroughly decayed sheep manure, and one-fourth leaf soil, to which must be added sufficient coarse sand to keep the whole open. After potting, the plants must be again placed in the same position, and, as they require it, plenty of room given. Careful attention to watering is necessary, as they must not be allowed to get dry. Air must be given on all suitable occasions. The flower-stems, as they require it, should be supported with small neat sticks. About May, the plants will commence to bloom, and continue to do so for a couple of months. The best flowers should be selected, and cross-fertilised with a camel-hair pencil, in order to produce a good strain of seed for future sowing. The attention of horticulturists appears to be almost wholly confined to the innumerable hybrids raised from amplexicaulis, arachnoidea, corymbosa, integrifolia, purpurea, thyrsiflora, and a few others. Very few pure species are seen in cultivation, although most of them are well worth growing.

A genus of stove, greenhouse, or nearly hardy evergreen shrubs, closely allied to Petræa. Flowers inconspicuous, disposed in axillary cymes; corolla-tube short, with the limb four-lobed. Fruit a very ornamental small juicy berry or drupe. The following mode of culture has been recommended: "After the old plants have been cut back in the spring, and started into growth, the young shoots will strike as readily as a Fuchsia, and with exactly the same treatment. In order to make good plants, short-jointed cuttings should be selected; and, as soon as these are struck, they should be potted into 2½in. pots, using a compost of equal parts loam and peat, with a little charcoal and river sand. When they commence to grow, after being potted, remove to a pit or house with a temperature ranging from 60deg. to 75deg. Pinch out the tops of the plants as soon as they have three pairs of leaves, and whenever each of the laterals has made two pairs of leaves, pinch out their points, and continue this operation with all the rest of the shoots till the beginning of August, at the same time keeping off all the flower-buds. The next shift will be into 4in. or 5in. pots. They should always have plenty of light and air, but more especially after they come into flower."

CALLISTACHYS. See Oxylobium.

CALLISTEMMA. See Callistephus.

CALLISTEMON (from kallos, beauty, and stemon, a stamen; in most of the species, the stamens are of a beautiful scarlet colour). ORD. Myrtaceæ. Handsome greenhouse evergreen shrubs or trees, having the inflorescence rising from the old branches in crowded spikes, as in the species of Melaleuca, but with the stamens free, as in Metrosideros. Leaves elongated, stiff, alternate, usually lanceolate. All the species of this genus are very ornamental and neat in habit. They are well adapted for a conservatory. The soil best suited for them is a mixture of loam, peat, and sand. Ripened cuttings strike root in sand, under a hand glass; seeds are frequently produced on large plants, and these may also be used to increase the stock, but they do not produce flowering plants for a considerable time; whereas plants raised from cuttings, taken from flowering plants, come into flower when small.

CALLUNA (from kalluno, to sweep, from the use of the plant in brooms). Common Ling; Heather. ORD. Ericaceæ. A small hardy spreading shrub, very common throughout Northern and Central Europe. Corolla campanulate, four-lobed, shorter than the calyx. For culture, see Erica.

> C. vulgaris (common).* fl. disposed in long, terminal, spicate racemes. July to September. l. trigonal, obtuse, very short, imbricating in four rows, having the margins revolute and the base sagittate. h. 1ft. to 3ft. Britain. There are numerous very ornamental varieties of this species, which are admirably adapted for planting in borders and clumps. The white-flowered (alba, Serlii, and Hammondi), flesh-coloured (carnea), and double-flowered varieties (fl.-pl.) are all well worth growing in shrubberies; aurea and argentea, with gold and silver coloured shoots, are also very ornamental. The value of the common form can scarcely be over-estimated for planting on barren hill sides or spaces; it affords excellent shelter for game, and food for bees.

CALLUS. The new formation at the end of a cutting before it puts forth roots; when the Callus is formed, it shows that the cutting is in a healthy state.

CALOCHILUS (from kalos, beautiful, and cheilos, a lip; referring to the beauty of the labellum or lip). ORD. Orchideæ. Interesting greenhouse terrestrial tuberous-rooted orchids, allied to Epipactis. Sepals yellowish-green; lip purple, covered with rich brown hairs. For culture, see Bletia.

> C. campestris (field). fl. greenish and brown. April to June. l. narrow, oblong, pointed. Stem leafy, slender, terete. h. 9in. Australia, 1824. (B. M. 3187.)

> C. paludosus (marsh).* fl. very similar in colour to those of C. campestris, but rather larger. May and June. l. rather broader. h. 9in. Australia, 1823. (F. A. O., part 4.)

CALOCHORTUS (from kalos, beautiful, and chortos, grass; referring to the leaves). Mariposa Lily. ORD. Liliaceæ. Handsome bulbous plants. Flowers showy, on erect scapes; perianth deciduous; three outer segments sepaloid, three inner ones much larger and broader, and bearded on the inside. Leaves ensiform. Bulbs tunicated. These have not, hitherto, been generally grown in the open air with much success; but in warm[245] localities and sheltered positions, they may be flowered outside. A frame, in a sunny situation, is the best possible place for their cultivation. Here they may be fully exposed to the sun and air, during mild weather, through the winter; and, when expedient, they may be protected from excessive moisture, as that is the primary cause of failure, rather than cold, for they are perfectly hardy, and capable of enduring all the frost we are likely to get. From May onwards, the lights might be wholly removed. From the end of June to August, the bulbs will be in bloom, when, if necessary, the flowers should be fertilised to secure seed; and when the capsules are forming, material assistance would be given by placing the lights on again, allowing plenty of air. Assuming that fresh bulbs are being planted, they should be in the soil early in the autumn, as nothing is more prejudicial than keeping them dry through the winter. A good depth of soil should be provided, composed of fibrous loam, leaf soil, and sand, in equal proportions, in a well-drained position. The bulbs must be planted 3in. deep, and some sand placed about them; they may be left undisturbed for years. Of course, where no frame can be provided, they may be planted in a well-drained, sunny position in the same soil. They are also easily managed in pots, but it is necessary to pot in the autumn, and keep in a frame. Through the winter, they must never be allowed to get dry, until the leaves are withering in the autumn, when water may be withheld.

Propagation. This may be effected by seeds or offsets, and by the tiny bulbs frequently produced on the upper portion of the stem. Sow seeds in pans, in a cool house or frame, as soon as ripe, or in the early part of the year, and keep the plants close to the glass during their early stages, as they are very liable to damp off. Sow thinly, so as to enable the young plants to pass a second season in the seed pots or pans. Early in the third season, pot off and plant out singly, encouraging them to grow freely. Propagation by offsets is the most usual method. With liberal treatment, most of the species increase pretty freely. The offsets are best removed when the plants are in a dormant state. They may be either grown in pots or pans, or planted out in pits or frames, until they reach flowering size. During the season of rest, it is the safest plan, with those in pots, to keep them in the earth in which they were grown.

FIG. 335. CAMASSIA ESCULENTA.

CAMASSIA (from Quamash, so called by the North American Indians, who eat the bulbs). SYN. Sitocodium. ORD. Liliaceæ. A small genus (two species) of handsome bulbous plants. Perianth of six segments, slightly connected at base, and spreading out horizontally, but not equally.[250] Leaves narrow, about 1ft. long, grooved down the inside. They thrive best in a sheltered, partially-shaded situation, but will do fairly well in almost any ordinary good garden soil. A compost of loam and leaf mould, with a liberal mixture of sharp sand, suits them best. They need not be disturbed for several years; but a top-dressing of rich soil or well-rotted manure may be given yearly. Propagated by offsets and seeds. The plants are so hardy that they ripen seeds in warm situations. These may be sown as soon as ripe, or the following spring, either in a warm situation out of doors, or in pots or boxes, under glass. The young plants make rapid progress, and should remain for at least two years in the seed beds. The best time for final transplanting is in February. Offsets are produced very freely, and should be removed either when in a dormant condition, or just previously to starting into fresh growth, and arranged in clumps or lines, placing a little sand about them.

CAMELLIA (named in honour of George Joseph Camellus or Kamel, a Moravian Jesuit and traveller in Asia, who wrote a history of the plants of the Isle of Luzon, which is inserted in the third vol. of John Ray's "Historia Plantarum"). Japanese Rose. Including Thea. ORD. Ternstrœmiaceæ. A genus of elegant hardy or nearly hardy evergreen shrubs or trees. Flowers large; sepals five or six, gradually passing from bracts into petals, the latter slightly cohering at the base; stamens numerous. Leaves coriaceous. By close attention to a few particulars in the management of these beautiful plants, much disappointment may be avoided, and a succession of flowers obtained from October till the following July. The fact of the buds frequently dropping off, deters many would-be growers from attempting the culture of the Camellia. Dryness of the atmosphere, and want of water at the roots, are generally the primary causes of failure; the remedy for these evils rests with the cultivator. The roots are apt to get matted together, compressing the earth around them into a hard ball, impervious to water; hence attention is necessary to see that the water poured into the pot thoroughly moistens all the soil. In order to form handsome plants, they should be trained with single stems to rods, and pruned, so as to make them throw out side branches from every part of the stem; they must not be placed too close to each other on the stage, or when planted out. A liberal supply of water is always necessary, but especially so during the flowering period. Plants that are required to flower early may remain in the warm house till they commence to blossom, when they should be removed to a cold place, such as the back of a greenhouse, giving them plenty of light. Those kept in a hothouse or vinery during summer, will flower in the beginning or middle of October; and a large plant, having from fifty to one hundred buds, will continue in flower till the month of January. Those that are removed early, will blossom in January, and so succeed the others. The plants that have finished flowering should be brought back to the hothouse, where they will begin to make new wood, and be ready to come in succession next season. By thus shifting the plants from a warm to a cold situation, a regular succession will be secured from October to July. The soil should be kept constantly moist, and in the summer months the leaves occasionally syringed. Camellias flower best when kept in small pots or tubs. In order to raise and exhibit these handsome plants to the best advantage, they should be grown in a separate house, of ample height, as they never look so well as when 6ft. or 8ft. high, trained in a conical form, with branches from the root upwards; and the plants should be raised near to the glass on a movable stage, which should be lowered as they grow. In summer, they may either be placed in the open air in a sheltered spot, or the glass roof of the house can be taken off. The hardier sorts, such as the Double-red, Blush, and Pæony-flowered, succeed in the bed or border of a conservatory, if the roof can be taken off in summer, so as to admit air. If this cannot be managed, they are better grown in portable pots or boxes. The most suitable time for shifting Camellias is directly after flowering; they should then be put into a vinery or hothouse, where there is a little heat; or the warmest part of a greenhouse. They will soon begin to make new wood, where they should be allowed to remain, amply supplied with water, till they form their flower buds, at the extremity and sides of the young growth. A few should then be removed to a cold place, and shaded during strong sunshine. In a few weeks afterwards, others may also be transferred, so as to have a regular succession of flowering plants.

Propagation. The red Camellias are generally propagated by layers, but cuttings will also succeed; the single red Camellia being raised by either cuttings, layers, or seeds. This latter forms suitable stocks on which to inarch or graft the rarer kinds. The ripened shoots of the preceding summer should be taken off in August, cutting them smoothly at a joint or bud. Two or three of the lower leaves should be taken off, and the cuttings planted firmly in the soil with a dibble. Some growers use peat earth and sand to strike in, while others prefer a loam mixed with sand and peat. The pans containing the cuttings should be kept in a plant or cold frame, without being covered with glasses, but shaded during powerful sunshine. In the following spring, such as have struck will begin to push, when they need to be placed in a gentle heat. The following September or October, the rooted plants will be fit to pot off, and in the second or third spring they may be used as stocks. Inarching or grafting is done in early spring, as soon as growth commences. When this process is completed, care must be taken to fix the pot containing the stock so that it may not be disturbed during the connection of the scion with the parent plant. The grafting being clayed over, is then covered with moss, to prevent its cracking. When independent grafting is resorted to, the[251] mode called "side grafting" is generally employed, as in the case of Orange-trees; but the operation of tongueing is generally omitted, as tending to weaken the stock. Liquid or other manure is not required; nor is it desirable to apply it, as it often, sooner or later, causes the destruction of the plants. As a rule, insects do not trouble this class of plants; but scale will sometimes appear, and can easily be removed by hand. Thrips occasionally put in an appearance, but a little smoke will quickly get rid of them.

FIG. 339. GROUP OF CAMPANULAS.

CAMOENSIA (named in honour of Luis Camoens, a celebrated Portuguese poet). ORD. Leguminosæ. A genus containing a couple of handsome species. C. maxima is the largest-flowered leguminous plant known. It thrives well in rich loam and leaf mould. Cuttings root in sandy loam, in bottom heat, if placed under a bell glass. It has not yet flowered in this country. The other species has not been introduced.

> C. maxima (greatest).* fl. cream-colour, yellow, 1ft. long, in short axillary racemes. Angola, 1878. (T. L. S. 25, 36.)

CAMOMILE. See Chamomile.

CAMPANEA (from campana, a bell; alluding to the shape of the flowers). ORD. Gesneraceæ. Stove herbaceous climbing perennials, the only one at present introduced being C. grandiflora. For cultivation, see Gesnera.

> C. grandiflora (large-flowered).* fl. in axillary tufts, at ends of long, axillary, and terminal peduncles; corolla white, lined and dotted with crimson. June. l. opposite, oval, acuminated, oblique, soft, crenated, stalked. Plant hairy. h. 2ft. Santa Fé, 1848. (R. H. 1849, 241.)

CAMPANULA (diminutive of campana, a bell; in reference to the shape of the flowers). Bell-flower; Slipperwort. ORD. Campanulaceæ. A genus of mostly perennial—rarely annual or biennial—herbs. Flowers blue or white, for the most part pedunculate, usually racemose, rarely spicate or glomerate. Radical leaves usually different in form from the cauline ones, especially in size. All the species of this genus are elegant when in flower (see Fig. 339), and are very largely grown. The dwarf varieties make excellent subjects for pot culture, rockeries, or the fronts of borders. A rather rich sandy loam, with plenty of drainage, suits these plants. The forms of C. pyramidalis may be kept in cold frames during the winter, and firmly repotted in summer, the crown of the plant being kept just a trifle raised above the soil, or they are at times liable to damp off, through the water lodging around the necks. During hot weather, the pots should be plunged in a bed of ashes. Campanulas are easily raised from seeds, which should be sown in spring.

General Culture. As a rule, few plants are so easily cultivated as these. The strong-growing kinds may be grown with the greatest success in ordinary garden soil, well enriched with manure, while the alpine kinds are easily managed on the rockery. Sow seeds of the annuals in April, and of the biennials in June, in the open, or in a cold frame. The perennials are chiefly propagated by dividing the roots, or by young cuttings, in spring—the latter is by far the best method of propagation with many of the species—or by seeds. Those kinds requiring special treatment are particularised, and those suitable to the rockery are so designated. Perennials, except where otherwise mentioned.

CANKER. This is a disease presenting very serious difficulties, principally in the cultivation of Apples and Pears. Both the trees and fruits, especially of some varieties, are, in many localities, so far injured as not to be worth cultivating. What causes the disease is not at all times known; indeed, it is, in most cases, but imperfectly understood. Were the causes better known, the remedy might generally be much easier found. Some of the primary causes are cold and undrained soil, severe and careless pruning, extreme variations of temperature, and excessive growth, made late in the season, when it has not sufficient time to get well ripened. Trees that are badly Cankered may often be improved by lifting, and replanting in improved or better-drained soil. Immediately the disease is detected in young trees, by the cracking of the bark or the skin of the fruits, measures should be taken to find the cause, if possible, and avert its progress. Some Pear-trees, in various localities, will not produce fruit without Canker in the open garden, but they will do so when planted against a wall; and as such may be the very best varieties, trees should be placed in the latter position. The removal of large branches, late in spring, will sometimes produce Canker, at the point where mutilation has taken place; and it may be caused by severe late pruning, which induces the growth of soft shoots that are almost certain to be injured by severe frosts. The difference in the seasons, as regards the amount of moisture, is one that can scarcely be provided against. One spring may be favourable to rapid growth, and the following may be most unfavourable, thereby arresting the natural flow of the sap until the latter part of the summer, when excessive growth will probably take place. Such checks invariably produce Canker. At times, the disease seems caused by the punctures of insects, in an early stage, on the stems or branches. In such instances, a thorough[261] cleansing, and a smearing of quicklime, made into a wash, often proves successful. Strong tobacco water will destroy insects, and a weak solution of sulphuric acid is also fatal to lichens and mosses, which should never be allowed to obtain a footing. The chief preventatives, therefore, are: Planting in well-drained soil; avoiding the use of any rank manure, to cause excessive growth; changing the old, or adding new, soil to injured trees; careful pruning, and the encouragement of early growth in spring, and subsequent well ripening in autumn.

FIG. 359. CANNA INDICA, showing Habit, Flowers, and Leaves.

CANNA (derivation uncertain; according to some, from cana, the Celtic name for cane, or reed). Indian Shot. ORD. Scitamineæ. A large genus of stove herbaceous perennials, very extensively employed in sub-tropical and other methods of summer gardening. Flowers spathaceous; anther attached to the edge of the petal-like filament. Leaves very ornamental. Few plants are more easily grown, or more quickly propagated. Seeds of many of the finer sorts may be bought cheaply from respectable seedsmen. These should be sown in heat, in February or March. A warm house or cucumber pit is the best place for sowing the seeds, which are very hard. If soaked in tepid water for twenty-four hours, germination will be materially stimulated. A mixture of sand and leaf mould is best for them, and a covering of 1½in. or 2in. of earth is not excessive. They should be sown thinly, in pans. As Cannas are gross, and have somewhat brittle roots in a young state, it is a good plan to sow the seed singly in small pots. This method preserves all the roots intact, and prevents any check in potting off or dividing the plants out of seed pans or boxes. When this is not done, the plants must be potted off singly, as soon as they have formed two leaves, 3in. pots being used for the first shift. The soil can hardly be too rich and porous. Equal parts rotted dung, loam, and sand, with a little peat, form a capital mixture for them. The plants must be kept in a growing temperature of 60deg. or so, during their earlier stages, and shifted as required into larger pots. Under proper management, the roots will fill 6in. pots by the middle or end of May. They ought not to be planted out till the end of May or the first week in June. Should fairly rich soil and a sheltered place be selected for them, they will not only grow, but flower freely during the late summer and autumn months. Cannas are also very effective indoors, either for greenhouse or room decoration. For these purposes they may be grown on in 8in., 10in., or even 12in., pots, with rich soil, and placed either in a stove, intermediate house, warm or cool conservatory, window, or room. Liberal supplies of manure water will be of very great benefit. Propagation is also effected by means of divisions; they form a root-stock very like some of the commoner and more free-growing Irises, each portion of which, with bud and roots attached, may be converted into an independent plant. The best mode of procedure is to divide the root-stock in early spring, when the pieces may be placed in 4in. pots at once; and, if plunged in a bottom heat of 60deg. or so, they will quickly resume root action and grow rapidly. They may also be propagated by division without bottom heat. Those who grow large quantities seldom put their plants in pots at all. Stored in pots or boxes for the winter, they are divided and placed singly in similar positions in the spring, and transferred from such vessels into the open air. The best open site for Cannas is in a sheltered spot, with a good depth of rich soil, and plenty of moisture. In such a position, their noble leaves are not so much injured by rough winds. After flowering, or at the end of the season, they may be lifted and stored away in boxes, or in pots of earth, in dry, frost-proof sheds, or under greenhouse stages during winter. In warm, sheltered situations, with dry[262] bottoms, they winter safely in the open, provided their crowns are covered with 1ft. of litter or cocoa fibre refuse. But where the soil is wet and cold, or the situation bleak and unprotected, they should be lifted and stored away, as already described.

CANNABINACEÆ. This order, of which the genus Cannabis (Hemp) is the type, is now merged into Urticaceæ.

CANNABIS (from the Greek word kannabis, used by Dioscorides, and that from Sanskrit canam). Hemp. ORD. Urticaceæ. A small genus, of but little ornamental value. Flowers racemose, diœcious. Nut two-valved, within the closed calyx. The undermentioned species is a hardy annual, of easy culture in ordinary garden soil. Propagated by seeds, sown in spring.

> C. sativa (cultivated). fl. greenish. June. l. on long stalks; leaflets from five to seven, long, lanceolate, acuminated; margins serrated. h. 4ft. to 10ft., or even 20ft. India, &c. This plant is cultivated very extensively for the sake of its valuable fibre. Well-grown plants have rather an ornamental appearance during the summer months. See Fig. 361.

CANNON-BALL TREE. A common name for Couroupita guianensis (which see).

CANSCORA (from Kansgan-Cora, the Malabar name of C. perfoliata, as yet unintroduced). SYN. Pladera. Including Phyllocyclus. ORD. Gentianeæ. Small, erect, simple or branched, stove or greenhouse annuals. Flowers stalked or sub-sessile. Leaves opposite, sessile or amplexicaul. Corolla funnel-shaped, with a four-cleft, unequal limb; the two outer segments equal, two lower ones combined a greater distance. Stems tetragonal. C. Parishii requires similar treatment to Balsam, and grows best in a soil to which chalk or limestone débris is added.

> C. Parishii (Parish's). fl. white. l. opposite, perfectly connate, so that the united two apparently form an exactly orbicular leaf. h. 2ft. Moulmein, 1864. Greenhouse. (B. M. 5429.)

CANTUA (from Cantu, the Peruvian name of one of the species). SYN. Periphragmos. ORD. Polemoniaceæ. Very pretty erect, branched greenhouse evergreen shrubs. Flowers in corymbs, at the termination of the branches, rarely solitary and axillary. Leaves entire or almost pinnatifid, alternate, petiolate, elliptic, acuminated, or cuneate-oblong, glabrous, or downy on both surfaces when young. They are of easy culture in a compost of turfy loam, leaf-mould, and sand, if good drainage is allowed. Propagated by cuttings, placed in sand, under a hand glass. In the western parts of England, these plants—particularly C. buxifolia—thrive remarkably well in sheltered situations.

CAPPARIDEÆ. An order of herbs or shrubs, rarely trees. Flowers clustered, or solitary; sepals four to eight, imbricate or valvate; petals four, arranged crosswise, sometimes, but rarely, five, or eight, rarely absent. Leaves alternate, very rarely opposite, stipulate or exstipulate. The order is distributed throughout the tropical and warm temperate regions of both hemispheres, the frutescent species being largely represented in America. There are about twenty-three genera—the best-known being Capparis, Cleome, and Cratæva—and about 300 species.

CAPPARIS (kapparis, old Greek name used by Dioscorides, from Persian kabar, Capers). Caper-tree. ORD. Capparideæ. Greenhouse or stove evergreen shrubs, of considerable beauty. Calyx four-parted; petals four; stamens numerous; succeeded by a berry. They thrive best in a compost of well-drained sandy loam. Cuttings of ripe shoots will root in sand, under a hand glass, in moist heat. This genus contains about 120 species, but it is very doubtful if more than six are to be found under cultivation in this country.

CAPRIFOLIACEÆ. A rather large order of shrubs or herbs, often twining. Flowers terminal, corymbose, or axillary; corolla superior, regular or irregular. Leaves opposite, exstipulate. Well-known genera are: Linnæa, Lonicera, Sambucus, and Viburnum.

CAPRIFOLIUM. See Lonicera.

FIG. 364. FRUIT OF LONG AND ROUND CAPSICUMS.

CAPSICUM (from kapto, to bite; on account of the biting heat of the seeds and pericarp). ORD. Solanaceæ. Shrubs or sub-shrubs, rarely herbs. Peduncles extra-axillary, one-flowered. Leaves scattered, solitary, or twin, and quite entire. Many of the species, although possessing considerable beauty, are but rarely grown, either for decoration or for the use of their fruit; consequently, we confine our specific enumeration to the Common Capsicum, the Bird Pepper or Chili, and the Bell Pepper. The first two of these have long been in cultivation, for use either in a green state for pickles and for making Chili vinegar, or ripened and ground as Cayenne Pepper. Some sorts are exceedingly ornamental for greenhouse decoration in winter, if plants are well grown in rather small pots, and the fruit ripened under glass. The varieties producing small pods are the hottest, and consequently best suited for making Cayenne Pepper. These are generally called Chilies. All other varieties of Capsicum have a more or less pungent flavour, and those bearing larger pods are more profitable for use in a green state. The fruits of all are either red or yellow when ripe, and are of various sizes and shapes. Some are produced and stand erect on the upper side of the branches; others hang underneath. Fig. 364 represents hanging fruits of Long and Round Capsicums, the shapes of which are produced by both red and yellow varieties.

Cultivation. Being natives of tropical countries, Capsicums cannot always be depended upon to thoroughly ripen in the open air; but a good crop of green fruits may generally be obtained by preparing the plants early in the season, and planting out in a warm situation.

Sow the seeds in February or early in March, in pots or pans, placing them in heat; and so soon as the plants are large enough, pot off singly into 3in. pots, still keeping them in heat until well rooted. Place them into 6in. or 7in. pots before they become starved; and gradually harden off and plant out about 2ft. asunder, in June. The fruits ripen better if the plants are placed against a south wall and tacked on to it. The safest plan to obtain a crop of ripe fruits is to cultivate under glass. Pots of 7in. diameter are large enough. Rich soil must be used, and any spare frames are suitable in summer. Plenty of water and frequent syringings should be applied, as the plants are very liable to injury from red spider and other insects if this is in any way neglected. The fruits will keep some time after being ripe, but are never better than when fresh gathered; they may, however, be kept on the plants for a considerable period.

Sorts. Chili, Long Red, Long Yellow, Small Red Cayenne, Round Red, and Round Yellow. Good ornamental varieties are: Little Gem, a very dwarf variety, of comparatively recent introduction, covered with small, erect, red pods; and Prince of Wales, free fruiting, with hanging bright yellow pods.

> C. annuum (annual). Common Capsicum. fl. white, solitary. June. Petioles glabrous. fr. oblong, pendulous, and erect, red or yellow, variable in shape. h. 1ft. to 2ft. South America, 1548.

> C. grossum (large). Bell Pepper. fl. white. July. India, 1759.

CAPSULAR. Like a capsule.

CAPSULE. A dry dehiscent seed vessel or fruit.

CARAGANA (Caragan is the name of C. arborescens among the Monguls). Siberian Pea-tree. ORD. Leguminosæ. Very ornamental hardy deciduous trees or shrubs. Flowers usually yellow, axillary, either solitary or crowded, but always single on thin stalks. Leaves abruptly pinnate, the midrib ending in a bristle or spine; leaflets mucronate. They are well adapted for shrubberies, and are of the easiest culture in sandy soil. Propagated by cuttings, made of the roots, or by seeds; the low-growing shrubs by seeds and layers. Caraganas are generally increased by grafting on C. arborescens, which is easily raised from seed, sown when ripe or in spring.

> C. Altagana (Altagana). fl. yellow; pedicels solitary. April to July. l. with six to eight pairs of glabrous, obovate-roundish, retuse leaflets; petiole unarmed. h. 2ft. to 3ft. Dahuria, 1789. Shrub.

April. l. with two pairs of leaflets, approximating the top of the petiole, obovate-cuneated; stipules membranous; petiole furnished with a short spine at the apex. h. 2ft. to 3ft. Siberia, 1752. Shrub. (S. B. F. G. 3, 227.) There are one or two varieties of this species.

> C. jubata (bearded).* fl. white, suffused with red, few; pedicels solitary, very short. April. l. with four or five pairs of oblong-lanceolate, lanuginously-ciliated leaflets; stipules setaceous; petioles somewhat spinose. h. 1ft. to 2ft. Siberia, 1796. Shrub. SYN. Robinia jubata. (L. B. C. 522.)

Contact the Foundation as set forth in Section 3 below.
1.F.
1.F.1. Project Gutenberg volunteers and employees expend considerable effort to identify, do copyright research on, transcribe and proofread works not protected by U.S. copyright law in creating the Project Gutenberg™ collection. Despite these efforts, Project Gutenberg™ electronic works, and the medium on which they may be stored, may contain “Defects,” such as, but not limited to, incomplete, inaccurate or corrupt data, transcription errors, a copyright or other intellectual property infringement, a defective or damaged disk or other medium, a computer virus, or computer codes that damage or cannot be read by your equipment.
1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right of Replacement or Refund” described in paragraph 1.F.3, the Project Gutenberg Literary Archive Foundation, the owner of the Project Gutenberg™ trademark, and any other party distributing a Project Gutenberg™ electronic work under this agreement, disclaim all liability to you for damages, costs and expenses, including legal fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH DAMAGE.
1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a defect in this electronic work within 90 days of receiving it, you can receive a refund of the money (if any) you paid for it by sending a written explanation to the person you received the work from. If you received the work on a physical medium, you must return the medium with your written explanation. The person or entity that provided you with the defective work may elect to provide a replacement copy in lieu of a refund. If you received the work electronically, the person or entity providing it to you may choose to give you a second opportunity to receive the work electronically in lieu of a refund. If the second copy is also defective, you may demand a refund in writing without further opportunities to fix the problem.
1.F.4. Except for the limited right of replacement or refund set forth in paragraph 1.F.3, this work is provided to you ‘AS-IS’, WITH NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.
1.F.5. Some states do not allow disclaimers of certain implied warranties or the exclusion or limitation of certain types of damages. If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.
1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the trademark owner, any agent or employee of the Foundation, anyone providing copies of Project Gutenberg™ electronic works in accordance with this agreement, and any volunteers associated with the production, promotion and distribution of Project Gutenberg™ electronic works, harmless from all liability, costs and expenses, including legal fees, that arise directly or indirectly from any of the following which you do or cause to occur: (a) distribution of this or any Project Gutenberg™ work, (b) alteration, modification, or additions or deletions to any Project Gutenberg™ work, and (c) any Defect you cause.
Section 2. Information about the Mission of Project Gutenberg™
Project Gutenberg™ is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.
Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg™’s goals and ensuring that the Project Gutenberg™ collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg™ and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.
Section 3. Information about the Project Gutenberg Literary Archive Foundation
The Project Gutenberg Literary Archive Foundation is a non-profit 501(c)(3) educational corporation organized under the laws of the state of Mississippi and granted tax exempt status by the Internal Revenue Service. The Foundation’s EIN or federal tax identification number is 64-6221541. Contributions to the Project Gutenberg Literary Archive Foundation are tax deductible to the full extent permitted by U.S. federal laws and your state’s laws.
The Foundation’s business office is located at 809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up to date contact information can be found at the Foundation’s website and official page at www.gutenberg.org/contact
Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation
Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.
The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.
International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.
Section 5. General Information About Project Gutenberg™ electronic works
Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support.
Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.
Most people start at our website which has the main PG search facility: www.gutenberg.org.
This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
