ROSES (continued) Natural Order Rosace&. Genus Rosa

For the characters of the Genus, history and descriptions of the cultivated kinds, together with lists of hybrids and garden varieties, the reader is referred to vol. i. pp. 149-164.

The grower of Roses has to combat the attacks of numerous enemies, not only among insects, but the more insidious depredations of fungoid parasites. Among INSECTS, various species of Greenfly (Aphis) are most in evidence, swarming in thick masses round the extremity of the growing shoots, and sucking sap continually. This constant drain upon the tenderest portions of the plant has a prejudicial effect upon the character of the branches formed from these shoots, and an effort must be made to get rid of the pests. Whatever is attempted in this direction must be thorough, for the fecundity of the Aphis is so astonishingly great and rapid, that a single individual left upon a Rose-tree is sufficient to ensure a swarm round every shoot a day or two later. Many remedies are in use, such as solutions of tobacco, quassia, soft soap, and numerous patent prepara- tions. All these are good, but in using them care must be taken to thoroughly syringe the plants a few hours later with clean water, or the remedy will prove worse than the disease. Our own experience is

that when the succulent growing tips of the branches have been much attacked by these pests, they do not develop into healthy wood, and that the heroic remedy is the best—that is, to cut off the infested shoots and put them on the fire at once. That is a certain end to the insects, whereas many of the washes merely stupefy for the time, and the Greenfly revive to found new colonies, But not only does the Aphis injure Roses by its direct attacks, its sticky secretions provide a suitable material in which the low fungus Capnodiwm may flourish. Although this does not appear to attack the tissues of the Rose, its growth is unsightly, and clogs the breathing pores of the plant. The Lace-wing fly (Hemerobius) and the Lady-bird (Coccinella) should be encouraged, for their larve live entirely by sucking Greenfly dry. The larve of various species of Saw-fly (Lenthredo) and of moths innumerable feed upon the leaves, and these must be got rid of by hand-picking, which is at once more efficacious and more economical than the application of sticky messes to the stems. Several species

KERRIA 167

Fig. 1 is a section through the flower, and Fig. 2 shows the comb-like stipules at the base of the leaf-stalk, and the paired hook-prickles below. It occurs also with rosy and purple flowers.

Plate 80 illustrates one of the numerous forms of R. indica, the var. semyperflorens or Monthly Rose, with solitary flowers at the tips of the branches. The figure is about one-half the natural size.

Plate 81 is a drawing of R. lutea, var. punicea, the Austrian Briar, or Nasturtium Rose (Rose Capucine), so called on account of the resemblance in colour to the flowers of Tropwolum. Fig. 1 is a section through the flower after the fall of the petals.

Plate 82 shows a flower and buds of R. centifolia, var. muscosa, the Moss Rose, with its shaggy calyx and unequal prickles. The remarkable stipules are also well represented.

Plate 83 is a reduced drawing of the Hybrid Perpetual Baroness Rothschild, about one-half of the natural size.

Plate 84 gives further representation to the class of Hybrid Perpetuals in General Jacqueminot, drawn of the natural size.

In the Plate which forms the frontispiece to the present volume of this work, there will be found a representative of the Noisette section of Roses William Allen Richardson, a hybrid of recent production, but already a great favourite.

KERRIA Natural Order Rosacea. Genus Kerria

KERRIA (named in honour of W. Kerr, a botanist of last century). A genus of only one or two species of shrubs, native of China. Kerria japonica is frequently cultivated on account of its handsome orange- yellow flowers, abundantly produced at almost all seasons. It is an erect-growing plant, 5 or 6 feet high, with slender dark-green branches, and bright green, smooth, alternate leaves, which are oval-lance-shaped, sharply and doubly toothed. The flowers are of similar structure to those of Spirwa, with five petals and numerous stamens. But the form almost solely cultivated in this country is the double variety, flore pleno. The flowers are produced singly at the end of little side-shoots all along the upright branches, and are about an inch and a half across. It was

introduced about the year 1700. Cultivation, K. japonica (Japanese) is usually trained against walls. It succeeds in any good loamy soil, and is repro-

168 FLOWERS OF GARDEN AND GREENHOUSE

duced by means of cuttings taken from the young shoots. These are usually struck under a hand-light, but in many districts they will strike quite well if merely inserted where it is desired to grow them. Many years ago, noting the abundance of Kerria in the cottage-gardens of a village among the Surrey sandhills, we asked the sexton what it was “Oh,” said he “it’s just the J aponica. You just break off a bit and stick it in, and it grows.” Such was the rough method in practice there, but it was highly successful, and K. japonica flourished in every garden. It may also be propagated by layering the branches, or by dividing the plants. There is another variety (foliis variegatis) in which the leaves are prettily variegated with several shades of white, yellow, and green. Kerrias are sometimes. referred to as members of the genus Corchorus, but quite erroneously; the latter belonging to the Natural Order TILIACE.

WHITE KERRIA Natural Order RosacE&. Gents Rhodoty pos

Ruoporypos (Greek, rhodon, a rose, and typos, a type or model). A genus comprising but one Species, closely allied to and resembling Kerria, on which account it is called Rhodotypos Kerrioides (Kerria- like). It differs from Kerria, however, in the calyx lobes and the petals being four in each case, and the carpels one to four instead of five toeight. Itis a tall-growing shrub, about 15 feet high, with both branches and leaves in fours (decussate). The flowers are white, terminal and solitary, appearing in April. The plant was introduced from Japan m 1866. For cultivation, see Kerria,

BRAMBLES Natural Order RosacE&. Genus Rubus

Rusus (the old Roman name, derived from ruber, red). A genus or Prsing about a hundred Species of generally twiggy and prickly, trailing shrubs, of which our native Bramble or Blackberry (Rubus fruticosus) ane La taken as the type. They have conspicuous five-petaled flowers, white or pink, grouped in panicles or corymbs; and leaves simple oF a tetas ; They are chiefly grown for the sake of the multiple fraits, which are in many species juicy and edible. Several species, however are grown for the flowers or ornamental foliage, and it is only with these

that we are at present concerned. The species are abundant in the Northern Hemisphere, and a few occur in the Southern.

RuBus BIFLORUS (two-flowered). Chiefly grown on account of its pure white stems and branches, which are tall and covered with strong, recurved prickles. The leaves are broken up into three or five oval leaflets, which are inclined to be lobed, are doubly-toothed, downy above and covered with white wool beneath. The flowers are white, in axillary clusters of two or three; May. Fruit large, globose, golden yellow. Introduced from temperate Himalaya (1818). This has a very ornamental appearance when trained up a dark- coloured wall.

R. LACINIATUs (torn). Stems nearly round, straggling, well armed ;

prickles with dilated base. Leaves divided into three or five deeply- dissected leaflets. The flowers are white or rosy, in loose panicles; the petals three-lobed at the apex; June to September. Fruit large, black. This species, variety, or hybrid, which is of garden origin, and its true relationships unknown, is a very ornamental subject for scrambling over a fence or tree-stump. It may even be planted in a bed by itself and given a few tree-roots to grow around. R. oporata (fragrant). Stem erect, 3 to 5 feet high, devoid of spines, but covered with purple, glandular bristles. Leaves lobed, minutely toothed. Flowers rosy purple, 2 inches across; petals rounded ; June to August. Fruit reddish, flat and broad. Introduced from North America (1700).

R. ROSHFOLIUS (Rose-leaved). Stems erect, or nearly so, with scattered hooked prickles. Leaflets, five or seven, oval-lance-shaped, doubly and deeply toothed. Flowers white, solitary or in loose panicles ; August. Fruit orange-red. Himalaya (1811).

R, SPECTABILIS (showy). Salmon Berry. Stem erect, 5 to 10 feet high, unarmed or spiny. Leaves three-lobed, or divided into three egg- shaped leaflets, saw-toothed. Flowers very large, bright red, produced solitarily or in pairs, from the axils; May. Fruit egg-shaped, large red. Introduced from North America (1827).

Most Rubi are hardy, although even our tough Black- berry (R. fruticosus) occasionally receives a severe check through late frosts in early summer. Most garden soils will be found suitable for them, the chief care needed being to keep them within bounds by judicious cutting-back. They may be propagated from seed, - by layering the lower shoots, or by pegging down the tips of the long, arching ones, and covering slightly with earth. They soon root, and may then be separated and re-planted.

170 FLOWERS OF GARDEN AND GREENHOUSE

ALMOND, PLUM, AND CHERRY TREES Natural Order Rosacez. Genus Prunus

Prunus (the old Roman name for the Plum-tree). A genus comprising about eighty species of shrubs or trees with simple alternate leaves, white or red flowers, which are honeyed and disposed in corymbs, or racemes, or produced solitarily. There are five lobes to the calyx, five petals, fifteen to twenty stamens, and a single carpel. The species are natives of the Northern temperate regions, and rare in the tropics. Four species are indigenous to Britain. Most of the species are cultivated for the sake of the juicy fruit (Plums, Peaches, Cherries, etc.); those mentioned below are suggested on account of their showy flowers. atowy: The genus Prunus includes some of the most anciently cultivated of plants. Respecting the origin of some of these, such as the Almond, the Peach, and the Apricot, there has been much dispute. Persia and Northern Africa were formerly considered to be the natural home whence these desirable fruits have spread; but the generally accepted belief of modern botanists is that the Peach and Apricot are natives of China, and the Almond is indigenous to Southern Europe and the Levant. The Almond (P. Amygdalus), cultivated from very early periods, came to us by way of North Africa at some date prior to 1548, and somewhere about the same period we introduced the Apricot (P. : Armeniaca) from the Levant. Of the Peach (P. Persica) we have D0 certain records earlier than 1562; it appears to have come to us from Persia, where it had then been in cultivation for at least twelve hundred eae for Theophrastus in 3.0. 322 speaks of it as a Persian fruit, and 1b 1s suggested that he became acquainted with it through Alexander's expedition to Persia. The Almond is only grown in this country for the sake of its flowers, but on the Continent for its fruit; in favourable Seasons it ripens these in the South of England. : Principal Species, /RUNUS AMyGpaLus (Almond). Almond-tree. A ee a te from 10 to 30 feet high, with oblong-lance-shaped Patines ely toothed. Flowers pink or rosy (sometimes white), ped iced in abundance before the leaves, in March.

P. Avium (bird). Gean or Wild Cherry. Tree, 20 to 40 feet high, with stout trunk, and stout rigid branches curving upwards. Leaves pale green, downy beneath, on long stalks, and hanging down. Flowers in small umbels, drooping, the soft petals widely spreading; April or May. Fruit somewhat heart-shaped, black or red, bitter or sweet, but not acid ; juice staining. Native.

P. CERASUS (supposed native of Cerasus, in Pontus). Dwarf Cherry. A bush or dwarf tree, 6 or 8 feet high, with red bark, numerous suckers, slender drooping branches, and smooth, blue-green, coarsely-toothed leaves with short stalks. The flowers erect, in small umbels; the firm white petals notched, and not spreading widely ; April or May. Fruit round, red, with acid juice. A native.

P. Lavrocerasus (Cherry Laurel). Common Laurel or Cherry Laurel. A fine evergreen foliage shrub or tree, 6 to 10 feet high, with large, glossy, oval-lance-shaped leaves, dull beneath. The flowers in an erect raceme shorter than the leaves; April and May. Introduced from the Levant (1629). A number of varieties are to be found in our shrubberies, the chief differences being in the size or shape of the leaves. Var. latifolia is probably the best

P. LUSITANICA (Portuguese). Portugal Laurel. Evergreen shrubs 10 to 20 feet high, with oval-lance-shaped leaves, and white flowers in erect axillary racemes, longer than the leaves; June. Introduced from Portugal (1648). The var. myrtifolia has small leaves, and is of more compact growth.

P. Persica (Persian). Peach. Tree, 15 feet high, with smooth, lance-shaped, saw-toothed leaves, and pale or dark red flowers, smaller than those of P. Amygdalus, appearing in April or May. Fruit fleshy, covered with a velvety skin. The var. levis (Nectarine) has firmer, plumper fruit with smooth skin.

P. TRILOBA (three-lobed). Shrub, about 6 feet high, with three-lobed leaves. Flowers large, white or rosy, generally double, appearing before the leaves; March. Introduced from China (1857).

On a well-drained loamy soil all the species of Prunus will do well. Their roots run very near the surface, and, consequently, so deep a soil is not required as by many shrubs and trees of equal size. With some species there is a strong disposition to throw up numerous suckers, which are often a nuisance, and must be taken off. It is not advisable to use these suckers for propagation. Stocks for budding or grafting are usually raised from seed, which should be sown

hide A rich loamy soil, with a subsoil of an open character, is the most suitable for the genus Pyrus; they will not

succeed where the subsoil is clay. The species may be grown from seeds, which should be carefully selected from good healthy trees. Varieties should be propagated by means of buds or grafts. Cuttings may also be struck, but it is neither a reliable nor a speedy method; yet we have Se ‘ald good results from the mere careless sticking-in of apple the a gray any art being practised.

pinnately cut leaves, and red or white flowers. These are grouped in corymbose cymes, and consist of a pitcher-shaped or bell-shaped calyx with a contracted mouth and five spreading lobes; five petals inserted at the mouth of the calyx; many stamens, and one to five carpels. The latter are below and attached to the calyx-tube, and in association with it they develop into an egg-shaped or globose fruit consisting of a bony stone containing the seed or seeds, invested with a thin layer of flesh and a thick, coloured rind.

ica Thorns are most commonly used for hedging, and

there is nothing better for the purpose ; much of the beauty of our country in spring is due to this use. But Thorns that are allowed to develop naturally and form a round head are a magnificent sight when covered with their snowy blossoms. They thrive in almost any soil, light or heavy, and will survive any ill-treatment. - Whether grown as hedge, bush, tree, or choice pot-plant, the flowers come freely. They may be raised from seeds or cuttings, and the special varieties grafted or budded

Ds tena vigorous stocks of the common.species. The seeds may be sown

in drills or furrows, in well dug soil. This may be done soon after the seeds are ripe, or in the following spring; the drills being made about an inch and a half deep. For raising on a large scale, it is advisable to make a little heap of the “haws” soon after they are ripe, in order to root away the fleshy portion ; they are then mixed with sand and buried at a depth of five or six inches, where they are left till the next autumn, and then sown. They do not germinate rapidly, and a succession of young plants may be raised from the one sowing for several years. The seedlings are removed when about a year old, the roots shortened with a sharp knife, and transplanted in their permanent stations. They may be trained over walls, grown as standards, or kept for several years as pot-plants.

PHOTINIA ARBUTIFOLIA (Arbutus-leaved). Californian May-bush. A tree, from 10 to 20 feet high, with oblong- lance-shaped, saw-toothed leaves, and panicled white flowers; July. The leaf-stalks and young branches are bright red. Introduced from California (1796).

P. JAPONICA (Japanese). Loquat, or Japanese Medlar. A tree, from 10 to 20 feet high, with large oblong, wrinkled leaves, downy beneath. Flowers white, in drooping racemes; November. Fruit oval, “the size of a small apple,” pale orange tinged with red, of a sub- acid flavour not unlike that of an apple; ripening in spring or early summer. The tree is sufficiently hardy to withstand our ordinary winters out of doors, but one of extra severity kills. Owing to the late flowering period the fruit cannot be ripened out of doors, but as a pot-plant in the stove it ripens easily. Introduced to Kew from China (1787).

P. SERRULATA (toothed). Chinese Hawthorn. A tree, 10 to 20 feet high, with large oblong, toothed leaves, and small white flowers in flat terminal corymbs; April to July. Introduced from China (1804).

Photinias are well suited for training against walls outside, where they can be given slight protection in very severe weather. They should in any case be given a sheltered position, and a light loamy soil. Propagation is effected by means of cuttings, or by grafting upon stocks of Pyrus Cydonia. The cuttings should be taken about three inches long from the side-shoots, inserted in sandy soil and covered with a bell-glass. Grafting is practised for out- door growth, and the method adopted is that known as cleft-grafting. April is about the best time for the operation, and the graft should be contrived as near the ground as possible.

The Potentillas are nearly allied to the Fragarias, or Strawberries, and have very similar flowers; they are chiefly distinguished by the character of the receptacle upon which the fruits (achenes) are developed. In Potentilla this is small and dry, but in Fragaria it is large and juicy. Most of the British species are neat and pretty, and in the early days of gardening in this country were probably more cultivated than they are now; but more than two hundred and fifty years ago we began to introduce exotic species. The first of these was P. grandiflora from Siberia (1640), and P. recta from South Europe in 1648, followed in 1680 by P. monspeliensis from France, and P. opaca from South Europe. The year 1822 saw the introduction of three good species _ from Himalaya—P. atrosanguinea, P. nepalensis, and P. splendens. In cultivation many hybrids have been produced, chiefly by crossing atrosanguinea and P. nepalensis, and these are in greater request than the original species. :

Sieeati pede pertins POTENTILLA ALBA (white). Stems weak, trailing; the

lower leaves of five leaflets, the upper with three. Flowers nearly an inch across, white with an orange ring near the centre; February to August. Native of the European Alps.

P. ATROSANGUINEA (dark-blood.) Silvery Cinquefoil. Stems hairy, branching, about 2 feet high. Leaves trefoils; the leaflets saw-toothed, and covered with silvery down beneath. Flowers 1} to 2 inches across, of a beautiful dark crimson colour; May to July. Plate 85.

P. comarum (arbutus-like). Marsh Cinquefoil. Stems more or less creeping, purple-brown. Leaflets five to seven, pinnately arranged, coarsely saw-toothed, pale beneath; stipules large. Petals dark purple- brown, smaller than the purplish sepals; June and July. Fruits many achenes, disposed on a crimson, dry, spongy cone, like the fruit of Arbutus. A native of our bogs and marshes.

P. rruTICOSA (shrubby). Stem shrubby, with flaking bark, 2 to 4 feet high. Leaflets three or five, lance-shaped, margins turned back, and untoothed; hairy. Flowers few, 14 inch across, rich yellow, in terminal cymes; June and July. Bracts lance-shaped. Native of Britain.

P. NEPALENSIS (native of Nepal). Very similar to P. atrosanguined, differing chiefly in the character of the radical leaves, which have five leaflets instead of three. Flowers in June and July.

_P. pyrenaica (Pyrenean). Stems 1 to 1} foot. Radical leaves long-stalked, with oblong leaflets, toothed only towards the tips; stem- leaves short-stalked, three- to five-lobed. Flowers large, deep yellow; petals very round, overlapping ; June to August.

History.

182 FLOWERS OF GARDEN AND GREENHOUSE

Radical leaves, with slender footstalks, and five pinnate leaflets. Stem- leaves with three leaflets, few, almost stalkless. Flowers few, 1 inch across, white; May and June. A native of Europe and Wales.

P. RUSSELLIANA (Russell’s). A hybrid, probably the offspring of P. atrosanguinea x nepalensis. Stem 1 foot. Leaves trefoils. Flowers nearly 2 inches across, of a rich blood-red colour; July to September. Many other hybrids and varieties will be found in the lists of good firms.

The Cinquefoils succeed as a rule in ordinary garden soil, but they prefer one that is sandy in character. The most appropriate situation for most of the species is the rock-garden or a stony bank. P. comarum, however, is used to a marsh habitat, and it would be well to give it a damp position and mix peat or cocoanut-fibre with the soil about its roots. They come readily from seeds or by dividing the roots; in the case of hybrids, of course, the latter method of propagation must be relied upon.

AVENS Natural Order Rosacea. Genus Gewin

GEUM (the old Latin name, said to be derived from the Greek geuo, to give to taste, the roots of Geum urbanum being aromatic). A genus of about thirty erect-growing, hardy, perennial herbs. They have large dissected radical leaves, of which the terminal leaflet is always much larger than the others, The stipules grow to the leaf-stalk. The honey ed grow solitarily or in corymbs, and are white, yellow, or red in colour. Like Potentilla, the calyx has, in addition to its five lobes, as many little bracts immediately below it. Petals five; stamens many, crowded; carpels numerous with thread-like styles. When these carpels have developed into a round head of achenes, the styles in some species have become hooked hairs, which catch in the fur of animals, and so secure distribution. The Species are found throughout the temperate and cold regions of the earth.

Two species of Gewm are indigenous in Britain: G. urbanwm, common in every wood and hedgerow, and @.

rivale, less plentiful by the sides of streams. The former has small

yellow flowers, and is apt to become a troublesome weed when introduced to the garden; but G. rivale was probably transplanted from its native streams at an early date. Of the exotic species, the white-flowered @. album, introduced from North America in 1730, was probably the first to be cultivated here. G. strictum, from the same quarter of the globe, was introduced in 1778, G. pyrenaicum from the Pyrenees, 1804. G. chiloense, the species most frequently cultivated, came from Chile in 1824. Several others are of more recent introduction, such as G. rheticum, thought to be a natural hybrid between G. montanwm and G. reptans, discovered in the Engadine in 1886. cionibeuiiad GEUM CHILOENSE (Chilian). Scarlet Avens. Stems glandular, about 2 feet high. Radical leaves interruptedly pinnate, leaflets lobed and boldly toothed. Stem-leaves three-parted, deeply cut. Flowers scarlet and copper-coloured, 14 inch across, in leafy terminal panicles; May to August. Plate 86. “This is often known in gardens by the incorrect name of G. coccinewm, which belongs to a distinct species. There is a very handsome var. flore pleno, with dazzling scarlet double flowers.

A genus of great importance to the gardener, nearly every one of the one hundred and sixty species being beautiful and suitable for cultivation, Mostly perennial, a few annual, herbs. Leaves variable, the radical ones frequently forming a rosette from which the flowering stems arise; stem-leaves usually alternate. The base of the leaf-stalk becomes a sheath, partially enclosing the next newer one. The flowers are white or yellow, rarely red or purple; honey producing, and the stamens ripening before the pistils. The calyx is tubular, with five lobes. Petals five; stamens ten, occasionally five ; ovary two-celled, two-lobed, two-styled. Fruit a two-beaked, two-valyed capsule, with many small rough seeds.

beta cctece Most of the species being perennial and tufted, are "most readily propagated by divisions. The rootstock of S. umbrosa sends out so many branches that it forms dense masses from which tufts may be cut, and these root readily without flagging. The smaller mossy kinds are as readily increased, but in their case the divided portions should be kept moist and in the shade until firmly rooted. Those with runners, like S. sarmentosa, should be pegged down in pots and rooted before separating from the parent. As a rule, the Saxifrages thrive best on rock-gardens, but a few (indicated in above list) are natives of marshy ground, and for these provision should be made by a liberal admixture of peaty soil in their compost. A very beautiful effect may be obtained by forming a special Saxifrage garden on the rockery principle, with S. wmbrosa and S. cotyledon occupying the heights, where their abundant and graceful panicles show to perfection. The mossy section would grow between and over the stones at various heights, according to size and robustness, whilst moisture-loving kinds could be accommodated at-the foot. The half-hardy kinds should be kept moder- ately dry during the winter, and care must be taken to prevent moisture gathering in the dense foliage at this period. They are all among the most easily cultivated of plants. The annual species sow themselves. | Description of Plate 87 represents Saxifraga sarmentosa, or Creeping. Plates 87 to 89.

panicles. The fertile flowers are small, but others develop their sepals enormously, at the expense of the sexual organs, and consequently are barren. In a normal flower the petals are four or five ; calyx five- toothed; stamens eight or ten; styles four or five. The species are chiefly Asiatic, but a few come from North America; the latter are more hardy, but less ornamental than those from Asia.

The Hydrangeas as garden plants are comparatively modern, H. arborescens, the species with which we have been longest acquainted, having been introduced from Virginia in 1736, and H. radiata from the same locality fifty years later. Both these species have greenish white flowers ; but in 1790, Sir Joseph Banks made us acquainted with a pink-flowered species by his introduction of H. Hortensia from China. This, in one or other of its varietal forms, has been popular in cultivation ever since. In more recent years new varieties of this species have been imported from Japan, in addition to those raised by selection in our own gardens, and new species have been discovered. Amo these are H. paniculata (1874), H. Thunbergii (1874), H. petiolaris (1876), and H. scandens (1879)—all from Japan. The likeness subsisting between. these showy balls of sterile blooms and those of Vibwrnum, or Guelder Rose, is very striking ; and one is not greatly surprised to learn that the same causes produce similar results in Orders as widely separated as are SAXIFRAGEZ and CApPRIFOLIACER,

HYDRANGEA ARBORESCENS (tree-like). Stems 4 to 6 feet. Leaves oval, inclined to heart-shaped, the upper ones lance-shaped, coarsely toothed, pale and covered with minute down beneath. Flowers greenish white, in rather flat corymbs, and with an agreeable scent ; July and August.

H. Horrensia (a former name of the genus). Common Hydrangea or Hortensia. Stems 2 to 5 feet high. Leaves broadly oval, saw-toothed. Flowers large, pink, white or blue, according to the nature of the soil, variable in size and number of parts, but disposed in large globular corymbs ; fertile individuals few ; April to September. Plate 90. There are several varieties of this species, among them var. Inndleyi (includ- ing the garden vars. roseo-alba and cwrulescens), with the outer flowers only radiate, white, rosy or blue; var. otaksa, with nearly all the flowers sterile; var. stellata, flowers yellowish green, turhing to rose-colour, all sterile; var. variegata, leaves variegated red or yellow.

: H. PANICULATA (panicled). Somewhat similar, but leaves often in

threes, downy ; flowers small, white, in a dense panicle a foot long; June to September. When well-grown all the flowers are sterile and pure white, in an enormous panicle. :

H. PETIOLARIS (stalked). Stem slender, branching, rooting into its support, like ivy. Flowers white in broad flattened cymes, 6 to 8 inches across; April and May. Requires the protection of a cool greenhouse.

H. QUERCIFOLIA (oak-leaved). Stems 4 to 6 feet. Leaves large, oval, lobed and toothed in a similar manner to those of the Oak. Flowers greenish white, or pink, in large flattened corymbs; June to August.

H. Tuunserei (Thunberg’s). Stems 2 to 3 feet high. Leaves smaller. Flowers blue or rosy, in terminal cymes; June; half-hardy.

Hydrangeas are readily propagated in summer by means of cuttings, or by taking off the suckers that grow up from the base of the stems. The plants require a sheltered position out of doors, and a rich, moist soil. Should the soil be light and poor, con- siderable improvement may be effected by mixing in decayed cow-manure. H. paniculata forms a shrub 3 feet high and produces in summer enormous panicles of white flowers; the old stems require to be cut down to the ground every year as soon as the flowers are over. In the South of England near the sea they are common garden bushes, so well do they thrive. To our mind, such bushes, four or five feet high covered with enormous corymbs of flowers, are better worth looking at or having than the more fashionable but stiff pot specimens, with a single stem upon which grows a big head of flowers, out of proportion to the size of its support. For this method of culture in pots, cuttings are placed singly in pots and brought on in a frame, which is kept close and warm, and there left through the summer. In early autumn they must be gradually hardened, and finally placed outside with full exposure to the sun. With this treatment the wood will ripen and the leaves fade. This is the signal for withholding the water that has hitherto been given in abundance ; and as the pots dry they should be removed to a cool house and wintered dry. Between the middle of January and the middle of February they should be turned out and repotted in five- or six-inch pots, using a mixture of equal parts loam and cow-manure. Increase the temperature and give water, and growth will at once commence. If the cuttings were taken from the tops of robust shoots they will soon show the flower-buds under this treatment; and as these begin to increase 2 size, artificial manure should also be given until the big corymb is well expanded. For bush plants in the garden the treatment is much simpler. Old plants that have flowered may be cut down, but a number of young shoots will break from the base. When partially ripened these may be : removed, and they will readily root; they may then be planted straight

into the border, and if well-watered and manured will soon form large flowering clumps. As a rule, where the soil is well-drained they surv!V°

DEUTZIAS Natural Order SAxIrRAGEX. Genus Deutzia

DEUTZIA (name given by Thunberg in honour of his friend Johann Deutz). A small genus, comprising only about seven species, of deciduous shrubs of a very ornamental character. They have opposite, stalked and toothed leaves, oval or lance-shaped, and covered with star-shaped hairs. The flowers are white or pinkish, scentless. Petals five; stamens ten, five long and five short; the filaments often dilated, and three-lobed near the extremity, the middle lobe bearing the anther, Ovary three- or four-celled, with as many erect thread-shaped styles. Capsule globular, leathery, opening by several slits in the middle. Natives of India, China, and J apan. They are spring-flowering shrubs, but by forcing, flowers are obtained from J anuary onwards.

: EUTZIA CORYMBOSA (flowers in corymbs). Stems 5 feet high. Leaves oblong or lance-shaped. Flowers white, corymbs panicled. Native of Himalaya.

D. CRENATA (round-toothed leaves). Stems slender, 4 to 8 feet. Leaves broad, lance-shaped, with rigid teeth ; rough to the touch. Flowers white, in panicles or racemes. The ordinary form is better known in gardens as D. scwbra, but there is a true D. scabra (not cultivated); it is also known as D. Fortunei, but these are mere garden names. There are two double varieties: flore pleno, with pink and white flowers; and purpurea plena, with flowers of a deeper tint. Native of Japan.

D. STAMINEA (prominent stamens). Stems 3 feet high. Leaves broad, lance-shaped, woolly beneath. Flowers white, fragrant ; corymbs many-flowered; May and June. Native of Himalaya.

Deutzias are hardy shrubs in the South of England, and may be grown in the border, but a wintry spring is likely to spoil that season’s floral display so far as these plants are concerned. It has, therefore, been customary to grow them more as pot-plants, and as subjects for forcing in order that their flowers may be available in the first days of the year. They are not particular as to soil or position, but a rich loam is the most suitable. For potting this should be improved by the incorporation of well-rotted cow- manure and sharp sand. Cuttings should be taken from the lateral shoots, and slipped off with a heel. These may be rooted in a shady border or in a cold frame. In autumn they should be potted if required for indoor use, or planted out in the shrubbery border. Those in pots should be placed in cold frames, where they will gradually develop during the winter, and from which they may be taken in succession and brought into a higher temperature gradually. They do well between 45° and 50°, producing leaves as well as flowers, whereas at a higher temperature the flowers precede the leaves. For foreing “D. gracilis stands unrivalled, but the same plant should not be forced two seasons in succession.

JAPANESE SPIREA

Natural Order SAxrrRAGEH Genus Astilbe

ASTILBE (Greek, a, without, and stilbe, lustre or brightness, from the 4 : smallness of the flowers). A small genus of branching herbs, with slender stems and compound leaves. The flowers are similar to those

of the genus Sazifraga. Stamens eight or ten; earpels three. They

are natives of Asia and North-East America. As garden plants they are distinctly modern, all having been introduced during ‘the present century. Astilbe japonica may be said to have a_ history, which ee

consists, however, of a record of its being bandied about from one genus

to another. Formerly regarded as a species of Spirewa, it was not only

JAPANESE SPIREA (ASTILBE JAPONICA) S 2/, Nat. size PL. 92

JAPANESE SPIREA 193

called S. japonica but S. barbata also. It has also been described under the name of Hoteia japonica, and may be found in gardens and in florists’ catalogues under either name, but its correct designation is Astilbe japonica.

ASTILBE JAPONICA (Japanese). Stems 1 to 2 feet high. Leaves compound, of nine to twelve lance - shaped or narrow-oval leaflets with toothed edges; the leafstalks hairy at the joints. The flowers are small, white, associated in dense racemed panicles; May and June. Native of Japan. Plate 92. There are several varieties in cultivation. One of these, var. Joliis purpurea, has purplish stems and leaves; another, var. variegata, has the leaves prettily marked with yellow, and denser panicles. .

A. RIVULARIS (growing by rivulets).. Stems 3 feet high. Leaflets Six or nine, oval, double-toothed, hairy. Flowers creamy to reddish; July and August. Native of Nepal.

A. RUBRA (red). Stems 4 to 6 feet high. Leaflets six, oblique, heart-shaped, toothed. Flowers rosy, in dense panicles; J uly to September. Native of India.

A. THUNBERGIT (Thunberg’s). Stems sub-shrubby, somewhat downy, 20 inches high. Leaves unequally pinnate; leaflets oval, toothed, of a yellowish hue. Flowers white, small, in erect pyra- midal panicles; May. Introduced from Japan within the last twenty years.

Principal Species,

The species mentioned are most suitable for damp places, although they will grow anywhere if freely watered and well-manured. Without these conditions, they may leaf freely, but their panicles of ‘flowers will be thin and insignificant, and the foliage liable to turn brown at the edges. A. rubra should be turned out of doors only in summer. They are all well-suited for pot- culture, and A. japonica and A. Thunbergii are much used for forcing. Propagation is effected in spring by division of the clumps, the portions being planted out in partial shade, in heavily-manured soil. In autumn, if required for decorative purposes, these should be taken up and potted in equally rich soil, the pots being then plunged into ashes or cocoa-nut fibre. When the new roots have had time to fill the pots, the plants may be successively brought into heat and forced into’ blossom early in the new year. From the time growth commences, water must be given in abundance, and to ensure a sufficiency the pots should stand in deep saucers of water. Large numbers are imported from the Continent every year for greenhouse or table decoration, and very commonly after they have served this purpose they are allowed to dry

GRASS OF PARNASSUS Natural Order Saxirracex. Genus Parnassia

PaRNAssIA (from Mount Parnassus, Dioscorides having named the common species Grass of Parnassus). A genus of about a dozen slender, erect perennial herbs, with entire, chiefly radical, leaves and solitary flowers, large in proportion to the plant. The floral parts are in fives, the petals thick and enduring. They are distributed throughout the Arctic and Temperate regions of the globe.

PARNASSIA PALUSTRIS (marsh-loving) is a native of our own bogs and wet moors. It attains a height of about 6 inches only. The leaves are heart-shaped, mostly radical, and these have long footstalks. The stem-leaves are stalkless, and only one to each stem, about half-way between rootstock and flower. The flowers are about an inch across, the leathery petals white, strongly veined with green; August and September.

Grass of Parnassus should be provided for in the garden by : utilising a damp-hollow, digging out the ordinary soil and filling in with peat. Here may be grown a number of bog-loving plants of considerable beauty, such as the Bog-bean (Menyanthes), Sundews (Drosera), Bog-Asphodel (¥, arthecium), and others. Parnassia may be propagated by seeds or by division of the rootstock.

plants have no right to this title, which is the botanical name for the Lilacs. All the species are worth growing, but the best-known and most widely cultivated is—

PHILADELPHUS CORONARIUS (garland), the Common Syringa, or Mock Orange. A bush with straight stems, 4 to 10 feet high. Leaves oval, saw-toothed, with the flavour of cucumbers both to the taste and smell. Flowers white, fragrant, in racemes, of which the terminal flower is five-parted; May. A native of Asia, but cultivated in this country for three hundred years. There are a number of varieties, some of which may be briefly mentioned. Vars, jlore pleno and primuleflorus have double flowers; var. Soliis-argenteo-variegatis has the leaves edged with white; var, foliis-aureis has golden-yellow leaves; var. nanus is a dwarf form.

P. GRANDIFLORUS (large-flowered). Stems slender, 6 to 10 feet high. Leaves nearly round, with irregular teeth ; downy when young. Flowers large, white, fragrant; June. Introduced from United States (1811).

P. MICROPHYLLUS (small-leaved). Stems and branches slender, erect. Leaves small, lance-shaped or oblong, not toothed. Flowers white, at end of shoots, solitary or in groups of three. Native of New Mexico (1883).

These plants thrive in ordinary garden ‘soil. Some of them soon grow into large shrubs unless well cut back each year. After the flowers have faded the flowering-stems should be cut away ; this will allow the new growths to ripen better, thus assuring a finer display of bloom next year, and will prevent the bush getting too large and unsightly. Propagation may be accomplished in spring by separating the suckers that shoot up around the base; or by taking cuttings from young shoots and striking them in a frame or under a

Ries (from Ribas, an Arabic name for some medicinal plant). A genus including between fifty and sixty species of hardy shrubs, with scattered, stalked leaves, solitary. Calyx tubular or bell-shaped, four- or five-toothed, often coloured ; petals minute, scale-like, in the throat of the calyx. Stamens four or five ; styles two. Fruit a globose berry. Natives of the Northern Temperate regions and the Andes; four species British. Several species are well known in gardens on account of the juicy fruit they produce, viz. R. grossularia, the gooseberry ; R. rubrum, the red currant; and R. nigrum, the black currant ; but with those we have no concern here, for their flowers are insignificant. The only species we shall describe are grown on account of their ornamental flowers, though the fruit of the first is very desirable.

CRASSULAS Natural Order CrassuLacEx. Genus Rochea

RocHEA (name commemorative of M. de la Roche, a French botanist). A genus comprising about four species of fleshy shrubs, with opposite fleshy leaves, connate at the base, quite entire. The flowers are borne in terminal umbellate cymes; white, pink, or searlet in colour. The calyx is five-lobed, the corolla tubular, salver-shaped, five-parted. Stamens five; carpels five. The species are restricted to the Cape of Good Hope. -

Rochea coccinea, the only well-known species, was first brought to England in the year 1710 from Table Mountain, South Africa; R. odoratissima came from the same neighbourhood in 1793, R. jasminea in 1815, and R. versicolor a couple of years later, None of these can be said to be widely grown by amateurs, though the professional growers turn out large quantities of R. coccinea and Rh. jasminea in bloom for decorative purposes. The reason for this neglect is to be found in the necessity for a hot-house in order to grow them well—unless one is a cottager, and possesses one of those deep window recesses where so many good things thrive.

RocHEA coccinea (scarlet). Stems 1 to 3 feet high. Leaves ovate-oblong, half-clasping the stem. Flowers searlet, an inch long ; June to August. Plate 93. : ____ RB. gasminea (Jasmine-like). Stems leaning upon the ground.

which the characters of the two are happily combined are now well known in gardens. They have pink, red, pale pink, and variegated flowers.

R. oporatissiMa (fragrant). Stems erect, 12 to 20 inches high, rough, sometimes branched. Leaves narrow-lance-shaped or awl-shaped. Flowers creamy white, pale yellow, or rosy, an inch long, sweet-scented, in many-flowered cymes; June and J uly.

R. VERSICOLOR (changeable). Stems erect, branched, 2 feet. Leaves lance-shaped, sheathing, with fringed edges. Flowers red, white within with the exception of a red margin, the colour from which gradually spreads all over the interior; in terminal umbels; fragrant at evening; May to September. .

The suggestions to be given under this head apply to the closely-allied genera of Rochea and Crassula, which are alike in general structure and habitat. They should all be grown in pots, for they need to be wintered in a greenhouse and kept dry. The soil that suits them best is a compost of sandy loam, three parts, to one part each of well-rotted manure, leaf-mould, and small brick rubbish. : They are propagated by seeds, but chiefly from cuttings taken in July. These should be laid in the sun for a couple of days at least before potting, in order to allow the cut portion to dry. This accomplished, insert in three-inch pots and place in the greenhouse in a dry and sunny position. Here they should remain until the following spring, when, as soon as growth commences, they should be shifted into larger (five-inch) pots. When again well established, check the growth by nipping out the growing point, and withhold water for a couple of days. This treatment produces a series of lateral shoots which will all bear flowers. By further stopping, these may each be made to send out branches until a bush has been formed sufficiently large to satisfy the grower, but with each stage in this process a shift should be made to a correspondingly larger pot, and the shoots must be tied out to neat little sticks. After flowering each shoot requires to be cut back until not more than two inches long, and when growth has again started cut back the longest roots and re-pot, giving them fresh sojl but no larger pots. Water should now be given sparingly, only in sufficient quantity to keep the soil moist until the new roots have got well hold of it. During the growing peri they should have sufficient water, but it needs to be given with care, and the drainage must be perfect. During winter it is essential that 10 more water than suffices to prevent the flesh shrivelling be given to them.

SICKLE CRASSULA Natural Order CrassuLacex. Genus Crassula

CRASSULA (from Latin, crassus, thick, from the leaves). A genus com- prising about one hundred and sixteen species of fleshy shrubs and herbs, mostly South African, and requiring greenhouse treatment in this country. The description of Rochea applies to Crassula, except that in the former genus the petals are united to form a tube, whilst in Crassula they are free throughout their length or united only at the base.

From the commencement of the eighteenth century, when Crassulas began to be introduced from the Cape, we have kept up a very steady importation of new species from the same source every few years, and yet very few of the species are at all widely grown. We might indeed go further and say only one species is fairly well known—C. falcata. This is the most striking from the floral standpoint, but several others are worthy of cultivation, if only for their ornamental or grotesque appearance. C. perfoliata appears to have been the first introduced (1700), C. falcata ninety-five years later, with many others in between and since, one of the latest being C. alpestris (1878).

CRASSULA ARBORESCENS (tree-like). Stems round, erect, 2 to 3 feet. The opposite leaves are flat and roundish, ending in a little hard point, glaucous, dotted above. Flowers large, rosy, in panicled cymes; May.

The species are distributed throughout the West and South of Europe, the whole of Africa, Mexico, and temperate Asia.

The plants now brought together by botanists into the genus Cotyledon were formerly separated into the genera Cotyledon, Echeveria, Pachyphytum, Pistorinia, and Umbilicus. The remembrance of this fact may obviate some confusion. One solitary species is indigenous—Cotyledon umbilicus, the Navelwort, confined chiefly to the Western coasts. Among the earliest of the foreign species to be introduced was C. orbiculata, two hundred years ago, from the Cape, whence also came C. hemispherica in 1731, and C. fascicularis in 1759. Four years before the beginning of this century C. cwspitosa was introduced from California; whilst the well-known C. gibbiflora (1826), C. seewnda (1837), and C. retusa (1846) all came from Mexico. There are numerous hybrids in cultivation.

This is a hardy native of neat habit, suitable for growing in the crevices of old walls, where its singular flowers have a pretty effect.

Cotyledons make handsome pot-plants for decorative purposes, and are invaluable where ornamental bedding is carried out. They require winter protection, but in most cases the shelter of a dry frame, covered with mats in severe weather, is sufficient. Some, however, like C. gibbiflora, must be kept almost dry in a dry, warm house during the winter. The great danger to be guarded against in plants of this character is damping-off from too much moisture at the roots, or from drip upon the leaves. A well-drained sandy loam is the best for successfully growing Cotyledons. Many of the species and varieties are suitable for window-gardening. Propagation is sometimes effected by seeds (necessarily so in the case of annual species), but usually by cuttings and divisions, or by detaching -leaves and striking them. Cuttings should be taken early in summer, and they should be allowed to dry at the severed part before putting them into a close, cool frame until rooted. Early in autumn these cuttings should be potted in sandy - loam and placed in the greenhouse. Some of the species produce few or no offshoots, and from these leaves must be carefully pulled off without injury in autumn. These are laid on dry sand in pans in a warm house. No water should be given until tiny plants have formed at the edge of

STONECROPS Natural Order CRASSULACEH. Genus Sedum

SEDUM (Latin, sedeo, to sit, from the half-recumbent habit of some of the species). A large genus of succulent herbs, usually with alternate leaves and white, yellow, pink, or blue flowers in cymes. The calyx is four- or five-lobed ; petals separate, four or five; stamens four or five; carpels four or five, distinct or joined at the base, styles short. The fruits are follicles. The one hundred and twenty known species are distributed through the Temperate and Arctic regions of the Northern Hemisphere, and a few in America. . No less than eight species of Sedwm are indigenous to Britain, and having regard to the neat habit of most of these, and the fact that we began introducing exotic species three undred years ago, it is no wild shot to surmise that from very early times our wild Sedums found place in our gardens. On the garden walls, the fanciful grottoes, and the roofs of garden sheds they would have their place, as we may gather from their names of Wall Pepper and Small Houseleeks; besides being used for bordering, for which purpose S. aere and similar dwarf forms are so suitable. The first foreign species to be introduced was S. Anacampseros from the a Continent in 1596, followed by another European species, S. Cepwa, 1640. 8. Aizoon, an old-fashioned garden plant, came from Siberia in 1757. 8. Ewersii, one of the best, though rather tender, is also Siberian (introduced 1829); whilst the somewhat similar 9. Sieboldii came from Japan in 1836. Principal Species, SEDUM ACRE (acrid). Wall Pepper, or Biting Stone crop. Stems 3 to 5 inches. Leaves thick, oval-oblong, blunt, humped at the base ; closely laid one on another in six series: : Flowers yellow, about half an inch across; June and July.

In the garden they will grow almost anywhere, in the driest parts of the rock-garden, in the sunny border, or as parts of geometrical designs in ornamental bedding. Tender species like S. Siebuldii and S. Ewersii must be potted and given greenhouse protection. For potting, a loamy soil should be used, and a stone or two plunged in it, as they like to develop their roots round them. Propagation may be effected either by seeds, cuttings, or divisions. Cuttings may be taken at any time, but division of the clumps should be performed in spring to preserve their neat and regular appearance.

Sempervivums require no more special treatment than do Sedums. They all like a sandy soil, and they do not mind if it is hot and dry. Droughts have little terror for them. They are, therefore, very suitable for the driest coigns of rockwork old walls, old roofs, and so forth. The more tender greenhouse species must have some care taken of them during the winter, but in the middle of summer they may be turned out to decorate the beds or borders with advantage to both plants and beds. They are increased by seeds or divisions. Most of them produce offsets, and these, if separated, will soon send out independent roots and grow. Several of the species found in Madeira, i.e. S. arboreum, S. dorami, etc., are handsome greenhouse plants thriving in a strong loamy soil.

MYRTLE Natural Order MyrtacE&. Genus Myrtus

Myrtus (Myrtos, the old Greek name). An extensive genus comprising about one hundred species of stove and greenhouse trees or shrubs. They vary greatly in size, from the dwarf M. nwmmularia, which spreads along the ground in the Falkland Isles, to the 30-feet tree of M. coriacea. The leaves are opposite and feather-veined, in some cases fragrant. The flowers consist of a top-shaped calyx-tube with four or five lobes ; an equal number of spreading petals ; twice as many, or an indefinite number of stamens; an ovary one- to six-celled, with simple style and stigma. The fruit is a dry or fleshy berry. The species are distributed throughout Tropical, Extra - tropical, and Western South America, Australia, New Caledonia, New Zealand, and the Mediterranean region.

208 FLOWERS OF GARDEN AND GREENHOUSE

One species of Myrtus has been held in great esteem from the most ancient times, and regarded as sacred to Venus. Of this, the typical species, M. communis, the Greeks wove the leafy shoots into wreaths for the victors in the Olympic games, and in other ways dignified it. To-day it is esteemed on account of the perennial freshness and fragrance of its varnished leaves, and the brightness of its sweet-scented flowers. Although none of the species is hardy throughout Britain, M. communis endures the winter tempera- ture of the extreme South and South-West of England. Even in other parts it may last for several years, and attain considerable size, but a little extra severity in the winter kills it right off. The Common Myrtle was introduced to Britain from Southern Europe in 1597, and other sepa have been brought from China, South America, and the West Indies since, but M. communis is the only one in general cultivation. Principal Species, YRTUS cOMMUNIS (common). Common Mpyrtle. Stem branching, 3 to 10 feet high. Leaves oval or lance- shaped, entire, glossy, marked with transparent dots.

POMEGRANATE Natural Order LyTHRARIEZ. Genus Punica

Punica (from the ancient name Maluwm punicum, or Punic Apple, pro- bably derived from punicans, ruddy). A genus comprising one solitary species, whose description will render unnecessary our usual divisions of matter. It has been in cultivation from very early times, the cool and refreshing pulp being greatly valued in warm climates. It appears to be a native of Persia and the neighbouring region, whence it has been introduced into the Tropics, and there widely cultivated. Our own country received the plant in the year 1548, and it was formerly far more widely grown here than is the custom at present. As it is very rarely that fruits ripen, or that even the flowers properly develop here, it is not to be wondered that more manageable plants have in a measure ousted it from our gardens. a. UNICA GRANATUM (grains). Stem woody, 20 to 30 "feet high. Leaves oblong or lance-shaped, entire, without the dots noticed in Myrtus. Flowers usually scarlet, occasionally white or yellowish ; calyx thick and fleshy at first, afterwards leathery, top- shaped, with five to seven lobes; the petals agree in number with the lobes of the calyx—except, of course, in the double varieties; June to September. Fruit about 3} inches across, with a tough leathery rind of a golden hue suffused with red. This rind contains a great quantity of tannin, and is made use of ‘in preparing morroco-leather. The fruit is singular from the fact that it is built up of two series of carpels, one above the other. The contained seeds are separately invested with a coating of clear pulp. In the typical form this is sweet to the taste, but in some of the varieties it is acid or astringent. There is a variety with large double flowers. This flowers annually on a south wall out of doors at Kew. There is also a whitish double-flowered variety. P. nana is much smaller in all respects, and scarcely exceeds 5 or 6 feet. The leaves are much narrower, flowers smaller, and the fruit _ searcely larger than a walnut. It was introduced from the West Indies _ as a distinct species in the year 1723. | _ P. nana is grown as a pot-plant for the conservatory, ae and on a wall in the open air at Kew. In some parts of Germany P. nana is grown in the form of little bushes a foot high, and made to flower profusely in autumn. It is used as a decorative plant for Il.—12

In other parts of the country, large pots or tubs are more suitable for it, as these may be kept in the greenhouse and put out of doors in hot sunny weather. The soil for potting should be a rich loam, the richer the better. It may be propagated by means of cuttings, layers, or suckers. Description of e extremity of a flowering shoot of Punica te10l.

CUPHEAS Natural Order LYTHRARIEZ. Genus Cuphea

CupHEA (Greek, kyphos, curved, from the shape of the flower). A genus comprising about a hundred greenhouse herbs, often viscid. Leaves oval or lance-shaped, entire, opposite, rarely whorled. Flowers axillary, scarlet, purple, or white, consisting of a long curved calyx-tube, which is brightly coloured, produced below in a short rounded spur, and above into six primary teeth with sometimes six smaller ones. The six petals, too, are small, and sometimes absent altogether. There should be twelve stamens, to agree in number with the other parts, but the twelfth one _ has been suppressed in development. Capsule two-celled, with long slender style. The species are natives of Tropical and Sub-tropical America.

Cuphea viscosissima, the stickiest of Cupheas, was introduced from North America in 1776; C. procumbens from Mexico in 1816, C. Melvillei from Guiana in 1823, C. miniata from Mexico in 1843, C. ignea, also from Mexico, in 1845. Among the more recent introductions may be mentioned C. hookeriana (1877) and C.

Principal Species.

212 FLOWERS OF GARDEN AND GREENHOUSE

Although Cupheas require greenhouse treatment they eon are very sanity ear All those mentioned above are evergreen perennials, except C. lanceolata, which is biennial. Seeds should be sown in pans in January or February and placed in gentle heat. As soon as the seedlings are large enough to handle they should be potted singly in good rich loamy soil, and shifted as growth renders necessary, until they have become nice bushy plants in six-inch pots. When the pots are well filled with roots give liquid manure. If preferred, they may be bedded out in the open air during their first summer, and taken into the greenhouse later. They may also be increased by means of cuttings, struck in March or April in bottom heat. Old plants cut down will produce a number of new shoots from the roots, and if these are taken off and grown in a cool place during the summer they will be kept small and occupy little space in the greenhouse for their first winter, yet make admirable blooming plants for the next season.

C. RHOMBOIDEA (rhomboid) is a less interesting form with smaller purple flowers, the petals of a rhomboid shape.

The Clarkias are easily raised from seeds sown annually in the open border, either between March and May or in the autumn. They are not particular as to the character of the soil, but if this is rich the flowering will be profuse. They do not transplant well; they should therefore be sown thinly where they are to bloom, and be thinned out to a distance of ten or twelve inches. Autumn-sown plants begin to flower much earlier than those that were sown in spring. Description of Upper portion of Clarkia pulchella with buds, flowers, _ Flate103. and capsules.

EVENING PRIMROSES AND GODETIAS Natural Order ONAGRARIE. Genus Gnothera

CENOTHERA (Greek, oinos, wine, and thera, hunting ; classical name given to some plants whose roots were eaten to provoke the appetite for drink). A genus with about a hundred species, with rare exception, herbs. The leaves are alternate. Flowers solitary, or in leafy spikes or racemes, borne in the axils; large, honey-yielding, white, yellow, red, or purple. Calyx-tube four-angled, four-lobed. Petals four, stamens eight, ovary four-celled, style threadlike, stigma round or four-lobed. With one exception all the known species are natives of America, and but for @ few Tropical species these are confined to the Temperate regions. The extra-American species is a native of Tasmania. Enothera biennis, the Common Evening Primrose, and the best known of all the species, was introduced from North America in the year 1629. It has taken so kindly to British soil that in many places it is thoroughly naturalised and grows wild, whilst it has become one of the commonest of plants in cottage-gardens. &. mollissima was the next arrival, from Argentina, in 1732, followed by . fruticosa, from the United States, five years later. @. parviflora and G. pumila both came from North America in 1757 ; the large-flowered . grandiflora was introduced from North America in 1778; and é. odorata from Patagonia in 1790. The latter, which is well known 1) gardens, has become naturalised on the coasts of Somerset and Cornwall.

EVENING PRIMROSES AND GODETIAS 215

Many others have been introduced during the present century, among them the species formerly separated under the name of Godetia, and which are still known as such in gardens. Of these, @. Romanzovii was the first, from North America in 1817, followed by @. acaulis from Chili in 1821, @. amena from North-West America in 1826, E. vinosa from _ California in 1835, and @ Whitneyi from California in 1870. The principal reasons for formerly separating them were found in the fact that the Evening Primroses opened their flowers only after the sun had gone down, and were yellow or white in colour; whereas the Godetias were open all day, and were of various shades and combinations of rose and purple as well as white. These grounds of separation are now regarded as insufficient. The following species are perennial, except where otherwise stated.

CENOTHERA ACAULIS (stemless). Dwarf, 6 inches high. Leaves all radical, forming a rosette, deeply cut in a pinnate manner. Flowers large, white, turning red as they fade; May to

September. (Godetia acaulis.)

: CE. AM@NA (pleasing). Stem semi-erect, branching, 1 to 2 feet. Leaves slender, lance-shaped. Flowers rosy, each petal with a crimson spot; May to September. Annual. Plate 105 (Godetia amena). The var. rubicunda has erect stems, 2 fect high, with lilac-purple flowers; it _ is one of the parents of the numerous garden Godetias.

CE. BIENNIS (biennial). Zhe Evening Primrose. Stem _ erect, branched, 2 to 5 feet. Radical leaves broadly lance-shaped, stem-leaves more slender, faintly toothed and finely downy, especially the midrib. Flowers large, pale yellow, fragrant; June to October. Biennial. The var. grandiflora has much larger flowers than the type.

CH. CALIFORNICA (Californian). Rootstock creeping, horizontal; stems 2 feet. Flowers large, fragrant, varying white to pale pink with yellow centre; July.

CH. ExIMIA (choice). Stems 9 to 12 inches high. Leaves lance- shaped, downy, deeply but irregularly toothed. Flowers very large, white; July. Native of Rocky Mountains (introduced 1870).

CE. MISSOURIENSIS (native of Missouri). Stem prostrate, unbranched, 1 foot high. Leaves lance-shaped, margins and nerves downy. Flowers large, yellow; calyx spotted red; June to August. Introduced from United States (1811). The var. latifolia, with broader leaves, is the more desirable form ; it is represented on Plate 104 (B).

CE. oporaTA (perfumed). Stems sub-shrubby at base, branched, 1 to 2 feet high. Leaves lance-shaped, slightly toothed, and wavy. Flowers yellow, becoming red as they fade; April and May. Biennial.

CE. Romanzovit (Romanzow’s). Stems erect, 1 foot high. Leaves broad-lance-shaped. Flowers violet; June to September. (Godetia Romanzovii.)

CE. speciosa (showy). Stem sub-shrubby, 2 to 3 feet high. Leaves

broad-lance-shaped, deeply saw-toothed, almost pinnate, downy beneath. Flowers white, reddening as they fade; March to September. Plate 104 (A). CE. Warrneyi (Whitney’s). Stem 12 to 18 inches high. Leaves broad-lance-shaped. Flowers rosy, crimson-blotched, very large, very numerous; June to September. Annual. (Godetia grandiflora.) The var. concolor has white flowers; var. flammea, crimson flowers.

Under cultivation the @odetia section has produced "several good hybrids and garden varieties which are among the best of hardy annuals, though not nearly so widely known and grown as they deserve. In purchasing seed of these they must be asked for as Godetias. Duchess of Albany has white flowers, 3 or 4 inches across ; the Duchess of Fife also has white flowers; Lady Albemarle, a spreading dwarf plant, with showy crimson flowers ; Satin Rose, similar to the last mentioned, but with brilliant rosy flowers ; Princess of Wales, somewhat taller, with ruby-crimson flowers; The Bride, free flowering, white and carmine.

The cultivation of @notheras is a simple matter; they may be said to be everybody’s plants, for any person may grow them; they only require an introduction into the garden and they will sow and grow themselves. It is true they have some slight pre- ference in the matter of soils, and this is in the direction of those of a sandy nature. The dwarf Godetvas are very suitable for the herbaceous border, and they may be backed by some of the taller-growing species, such as &. biennis or @. speciosa. The tall, coarse-growing sorts are quite at home in the wild garden ; those that are small and of creeping

habit are suitable for the rock-garden. The annuals must, of course, be raised from seed sown out of doors in spring. The biennials are best sown as soon as the seed is ripe. Ifsown in March they will often flower in the following autumn, but this is not so desirable. Summer- or autumn-sown plants produce only a rosette of radical leaves their first season, and lay up much material in their thick tuberous root upon which they can draw next year for a profuse display of flowers. The perennials may be propagated by root-division as well as by seeds, and a third course is open in the taking of cuttings in spring and striking them in a cold frame. Some of the more compact, dwarf kinds, as well as the Godetias, make capital pot-plants for the cool greenhouse or conservatory.

FUCHSIAS Natural Order ONAGRARIEH. Genus Fuchsia

FUCHSIA (name commemorative of Leonhard Fuchs, a sixteenth-century German botanist). A genus consisting of about fifty species of shrubs or small trees. Leaves oval or lance-shaped, usually opposite, occasionally in whorls of three. Calyx fleshy, coloured, tube produced above the ovary, limb split into four lobes. Petals four, often of different colour from the calyx. Stamens eight, on long slender filaments. Style twice the length of stamens, with head-like stigma. Ovary crowned with eight honey-secreting glands. Fruita pulpy berry. With very few exceptions the species are natives of Central and Southern America; those that are not American come from New Zealand.

The first discovery of the Fuchsia was made by Father Plumier, who consecrated it to the memory of Fuchs, and published the name in 1703, calling his new species Fuchsia triphylla. The history of the introduction and popularisation of this genus has been often told. The story goes that about the year 1788 a sailor who had returned from South America brought with him a growing slip, which he presented to his wife or his mother. This was put in the window and carefully tended in honour of the absent one. In due time

it flowered, and there passed by the house a Mr. James Lee, who was a member of a firm of nurserymen still existing at Hammersmith. Struck by the newness of form and habit, he knocked at the door and offered to purchase the unknown plant, but was at first refused. By perseverance and the gradual increase of the amount offered until it reached a figure that was irresistible to the poor woman, he succeeded at last in carrying off the prize; then “kept it dark,” and struck cuttings as rapidly as possible, until he had a large stock when next year he put it upon the market, and realised—it is said—a profit of £300 upon his investment. This was probably Fuchsia coccinea, now known as a form of F. macrostema. Eight or ten years later another species—I. lycioides— was introduced ; and these remained the only representatives of the genus in our gardens until 1823, when another variety of F. macrostema, known as gracilis, was introduced. In the next few years several others were discovered, including F. venusta, F. thymifolia, and F. arborescens, all American species. The beautiful F. fulgens came from Mexico in 1830. The pretty, creeping F. procumbens, grown so much for the sake of its large crimson berries, is one of the New Zealand species (introduced 1874). F. penduliflora from tropical America is another recent (1879) introduction. These are the principal natural species, but from the early part of the present century Fuchsias have been so widely cultivated, have sported and been crossed to such an extent, that it is not always an easy matter to refer garden specimens to their proper types. In addition some distinctly new forms, such as F. corallina and F. dominiana, have been evolved by horticultural skill. princtpetipetion: FUCHSIA CORALLINA (coral-red). Stems woody, 20 feet high in suitable places; young stems red. Leaves with reddish upper sides, dark crimson beneath; in whorls of four or five. Flowers pendulous; calyx crimson, corolla dark plum-colour ; May to October. Grows luxuriantly in South-West England. Of garden origin.

F. CORYMBIFLORA (bunch-flowered). Stem branched, 4 to 6 feet. Leaves broad-lance-shaped, with red midrib; opposite. Flowers scarlet in terminal clusters; June to September. Native of Peru (1840).

F. FULGENS (shining). Stem 4 to 6 feet. Leaves heart-shaped-oval, toothed, shining; opposite. Flowers scarlet, large; calyx tapering; petals very short; in drooping terminal racemes; June to September. Plate 107.

F. MAcRosTEMA (large-stamened). Stems branched, 6 to 12 feet. Leaves oval, toothed, three in a whorl. Calyx scarlet, petals purple ; July to October. There are several good varieties of this: var globosa has the unopened flowers of a somewhat globular form ; sepals

The var. gracilis has very slender flowers, a character specially noticeable in the unopened bud. Both these forms are represented on Plate 106. F. coccinea is also a variety with dark crimson flowers. All the forms of F. macrostema are hardy in the warmer parts of England.

F’. PENDULIFLORA (hanging-flowered). Leaves large (3 to 4 inches long), oval, smooth. Flowers trumpet-shaped, rich crimson, shaded with maroon, 3 or 4 inches long; March. Native of tropical America (1879).

F. PROCUMBENS (trailing). Stems trailing. Leaves round, small. Flowers small, erect, calyx-tube yellow, corolla blue; May to October Berries large, crimson, remaining attached during the winter; very ornamental. :

F. SPLENDENS (splendid). Stem 6 feet. Leaves heart-shaped. Flowers orange-scarlet, tips of sepals green ; May and June. Greenhouse. Native of Mexico (1841)

I, TRIPHYLLA (three-leaved). Stems 1 to 2 feet. Leaves small, purplish beneath, bronze-green above. Flowers similar to those of F fulgens, petals shorter than sepals; brilliant orange-scarlet, in terminal racemes. Native of West Indies.

These are exceedingly numerous, and a list of only the best would fill many pages. As in similar cases, we can but give a brief selection from among the best to serve as a suggestion; but it must be remembered that many new varieties are put upon the market every season, and all such lists should be supplemented by the catalogue of a good trade grower. For our purpose it will be well to classify them first under the respective heads of Single- and Double- _ flowered, and then under the colour of calyx and corolla.

Fuchsias of all kinds are most readily propagated by cuttings, which root with freedom at nearly all times. For this purpose cutoff portions of the growing shoots that give no sign of flower buds. These should be put in pans of light soil and moist warm frames. When the young plants are rooted transfer them to beds of light, but very rich soil, in which they will come on rapidly if treated to abundant moisture; or pot them singly, with the same treatment as regards soil and moisture. When the pots are well filled with roots, liquid manure may be given freely ; and abundance of water should never be withheld. For the obtaining of new varieties hybridisation must be carefully attended to, the flowers marked, and the ripening of the berries watched. The seeds are embedded in pulp, which must be washed away, and the seeds sown at once. To obtain a suitable soil that is at once rich and light, dried cow-dung should be mixed with double the quantity of loam, neither being fine] y powdered. With such a compost the best results will be obtained, but all the same Fuchsias will do well in almost any garden soil. Except in the extreme south and west of our islands, Fuchsias out of doors must be cut down on the approach of hard weather, and the stump covered with a little heap of dry coal-ashes to keep off the frost. Pot-plants should be wintered dry and in a cool place.

GAURAS Natural Order ONAGRARIEH. Genus Gaura

Gaura (from the Greek gawros, proud or superb). A genus of about twenty annual or perennial herbs or shrubs with simple, alternate leaves varying in outline. The flowers agree in general with @nothera, but the calyx-tube is three- or four-angled, the petals more slender, white or rosy, turning red when fading; the fruit a hard woody nut with three or four prominent angles, and usually four-celled. As a rule the petals have a tendency to take the same upward direction; and the flower-cluster is a long terminal spike-like raceme. The species are natives of the warmer portions of North America.

Only one of the Gauras may be said to be a cultivated plant, and that we fear is but slightly known, and seldom seen. This is the species figured in Plate 108.

GAURA BIENNIS (biennial). Stems 4 to 6 feet high. Leaves oblong- lance-shaped, slightly toothed. Flowers irregular; sepals purple tipped ; petals white, then reddish, irregularly arranged; August to October. Introduced from North America (1762).

The seeds are sown, in March, in pans of light sandy soil, and these placed in gentle heat; or out of doors in a sunny border in May. When sufficiently grown the seedlings should be planted out at distances regulated by the erect or climbing habit of the species. They do best in light soils with a sunny position; otherwise requiring no special treatment. Where it is desired to grow the perennials as perennials, they must be lifted early in October and wintered in a cool greenhouse. In handling the plants, care should be taken to avoid being stung by the hairs, which are similar in their action and effects to those of our native Stinging Nettles.

MENTZELIAS Natural Order LoasEx. Genus Mentzelia

MENTZELIA (named in honour of Christian Mentzel, a botanist of Brandenburg, 1622-1701). A genus of herbaceous plants, with coarsely toothed, alternate or nearly opposite leaves, and orange or white flowers, which in most species expand only under direct influence of the sunshine, though several on the contrary wait until evening before opening. They differ from Loasa chiefly in the absence of the large scales from between the petals, the flatness of the latter, the more numerous stamens, and in the seed-vessel being untwisted. The plants, though not free from hairs, do not sting. The species are all American.

The most familiar species of Mentzelia are better known under the name of Bartonia, in which genus certain of them were formerly comprised. The plant figuring in seedsmen’s catalogues as Bartonia aurea is more correctly named Mentzelia Lindley. The first species to be introduced was M. aspera from the United States

PASSION-FLOWERS 225

PASSION-FLOWERS Natural Order PasstFLOREX. Genus Passiflora

PAssIFLORA (Latin, passio, passion, and floris, a flower). A large genus —one hundred and twenty species—of herbs and shrubs, chiefly climbers, with alternate, lobed, or entire leaves, and undivided tendrils. Flowers - produced in the axils, solitary or in racemes. The calyx-tube is short and urn-shaped with four or five lobes, often coloured on the inner face. The petals agree in number with the calyx-lobes, and alternate with these in the expanded flower, but are more deeply coloured. Inside these, and springing from a ring surrounding the base of the column, is a whorl of filaments, forming what is known as the corona. These are quite distinct from the stamens, and are really appendages to the petals. There are four or five stamens whose anthers are connected with the filaments by their middle. The ovary and stamens are supported by a stout column termed the gynophore, and from the summit of the ovary three styles with dilated stigmas radiate. The genus is chiefly American. Passijlora incarnata, the May Apple, from the Southern United States, appears to have been the species first introduced to English gardens, or more correctly to English green- houses, for it is a tender plant. P. lawrifolia, from the West Indies, and P. suberosa, var. minima, from Curacoa, followed in 1690. P. cerulea, the well-known and fairly hardy species, arrived in 1699 from Brazil. From this period new species were frequently being introduced, though many of these had no special horticultural interest; but in 1768 P. quadrangularis, the Granadilla, was brought from Nicaragua; in 1815 P. racemosa, the parent of several good hybrids, came from Brazil ; _and five years later the showy P. coccinea was introduced from the same country, whence also came P. alba (1830) and P. raddiana (1831). P. amabilis, another red species, from South America, appeared here in 1848. P. Innesii, a fine hybrid, was produced in 1870 by crossing P. alata and P. macrocarpa. Several species produce edible fruit, viz. -P. alata, P. edulis, P. lawrifolia, P. macrocarpa, P. maliformis (Sweet Calabash), and P. quadrangularis. These all mature their fruits

Passifloras are propagated by cuttings or seeds. The new shoots are taken off when about 6 inches long, with a heel of old wood, and these will be found to root quite easily if planted separately in small pots filled with sandy soil. Cuttings of P. cerulea will strike out of doors, but it is a more certain method to keep them in a close frame, or covered by a bell-glass in the greenhouse. All the species, except P. cwrulea, require greenhouse or stove treatment for successful flowering, and should be planted in a large pot, tub, or a shallow border. If there is no restriction of the roots these will wander to great distances and send up suckers where not desired. We have known them to penetrate foundations and send up shoots inside the dwelling-house against which they were planted. They are thirsty plants, but good drainage is a necessity. Turfy loam with an admixture of peat and sand will be found to suit them admirably, though ordinary garden soil will give good results. They all enjoy a liberal allowance of sunlight ; they are therefore adapted for training under the roof-glass of an unshaded greenhouse or conservatory. P. cerulea forms an excellent sereen.

BEGONIAS Natural Order Becontace”. Genus Begonia

BrGoNIA (name given in honour of Michael Begon, a French patron of botany). An extensive genus comprising about three hundred and fifty species, chiefly succulent herbs or under shrubs, and a few climbing plants, many of them having perennial tuberous rhizomes. Their leaves are more or less unsymmetrical, entire or lobed or toothed ; often hand- somely blotched with white and veined with red. The flowers are in many cases large and showy, bright coloured, white, yellow, scarlet, or rosy, the anthers and stigmas borne in separate flowers. The male flowers have four sepals, the female five. Stamens numerous, the filaments sometimes united at their base. Styles two to four, the stigmas branched or twisted. The fruit a capsule, frequently with wings, seeds minute. The species are distributed through moist tropical lands, and are especially abundant in South America. mistory The earliest species of Begonia introduced to our green- "houses were shrubby, and came from the West Indies and thereabout. Begonia nitida is the first of which there is any record, and it was introduced from Jamaica jn 1777. It is still a popular

in 1816. And so on, the new species coming in fairly rapidly ; but in 1858 the beautiful foliage-Begonias began to assert themselves with the introduction of B. rex. But the great impetus to Begonia-growing was given a few years later, when the tuberous-rooted species were introduced from South America. Among these should be mentioned B. boliviensis and B. Pearcei from Bolivia (1865), B. Clarkii, B. roseflora, B. Veitchtt, all introduced from Peru in 1867, and B. Davisii from Peru in 1876. Some of these have come from great altitudes in the Andes, B. Veitch, for instance, being found at an elevation of 12,000 feet above sea-level. From such forms magnificent hybrids have been raised, far exceeding the parent species in size and brilliance, and sufficiently hardy to serve as bedding plants, It is interesting to note, however, that, so far, all attempts to effect a cross between the shrubby section and these Andean tuberous species have failed. Possibly, at no very distant date, the

It is necessary that the natural ‘species mostly ‘cultivated should be known, but in recent years the garden hybrids have become far more important than their parents from the horticultural point of view. These exhibit great advance in the form, size, and colour of the flowers. They are at present very numerous, and the list is being extended every year. A few of the best may be briefly mentioned :—

ASCOTENSIS is one of the finest; the beautiful pink flowers borne in large clusters. In the South of England this may be used for bedding purposes.

GLOIRE DE ScEAUX. Upright habit, with bronzed leaves and numerous large, flat pink flowers, which appear in winter.

Incramu. Of dwarf habit, with dark foliage and reddish-pink flowers. Suitable for outdoor culture in warm situations.

KNowsLEYANA. Of more vigorous habit, with blush-tinted flowers, very serviceable for cutting during the first months of the year.

Paut Bruant. Very free bloomer; flowers of a soft pink hue.

President Carnot, Gloire de Lorraine, Triomphe de Lemoine, and the bedding varieties of B. semperflorens are other forms that may be recommen

Garden Hybrids.

Begonias are, as a rule, easily cultivated if one or two essential requirements are observed. The tropical species require a temperature of not less than 55° in winter, and a minimum of 65° in summer. A considerable number may be grown in an ordinary greenhouse, and some are suitable for cultivation ca the open air during the warm months of the year. The tropical species require shade in very bright weather, and a liberal allowance of fresh air at all times. ‘They all prefer a light, loamy, well-drained soil. They are propagated by means of cuttings inserted at any time, April being most preferable, as cuttings rooted at that time make large plants by the winter, when Begonias of the shrubby or evergreen section have most value. Some

of them ripen seeds freely, and from these a stock of plants is easily raised. Much interest and pleasure may be derived from crossing one species with another, the fact that the flowers are unisexual favouring hybridisation. Many valuable garden-plants have been raised within the last ten years in this way.

The Rea section and all its allies, such as heracleifolia, decora, Rajah, ete., are readily propagated by means of leaves. They are cut across the principal nerves, and, as a rule, from every cut a plant is developed, if the leaves are pegged down flat on sandy soil, and placed in a close frame till the plantlets are large enough to be potted Separately. B. rex is a most useful plant for shady borders in green- houses or cool ferneries, It is often used to decorate back walls, which are first covered with wire netting, supporting soil or sphagnum-moss, in which the Begonias are planted at intervals. The rea-socotrana hybrids have the double merit of being handsome foliage plants as well as having beautiful flowers, B. socotrana requires to be started in brisk heat in August, and grown in a tropical house close to the glass till it flowers in December. The hybrids between it and the Andean Begonias require similar treatment,

greenhouse is best for them at. this stage. When they have grown to touch each other, they should be planted singly in pots in light rich soil. If intended for bedding, five-inch pots are large enough for the final shift, but if wanted for the greenhouse, larger pots still should be given. Choice varieties are multiplied: by means of cuttings taken from the tubers in spring when the shoots are a few inches high. Seeds of a good strain of these plants are easily obtained from a Begonia specialist, or selected tubers may be procured cheaply and started in February. The tubers should be wintered dry in a frost-proof frame or shed.

MAMILLARIAS Natural Order Cactrx. Genus Mamillaria

MAMILLARIA (Latin, mamilla, a little breast, from the breast- shaped tubercles). A large genus (about three hundred species) of succulent perennials, with cylindrical or globular stems covered with numerous tubercles of variable shapes, spirally arranged, and bearing radiating cluster of spines at their apex. The plants in this genus are never tall, one foot being an extreme height, the more general stature being from 3 to 6 inches. The flowers are produced towards the summit of the plant, usually in a zone, each starting from the axil of a tubercle. They are tubular in form, both calyx and corolla coloured rosy, yellow, or white. The stamens are numerous, attached to the side of the tube; the style thick, long, and terminated by a three- to seven- rayed stigma. Fruit a smooth berry, containing many seeds. The

species are confined chiefly to Mexico, Brazil, Guatemala, and the warmer parts of North America, a few West Indian.

Mamillaria simplex, a native of Tropical America, was introduced from the West Indies as far back as 1690, but for more than a century it appears to have been the sole representa- tive of the genus cultivated here. This is, perhaps, not to be wondered at, when we consider that even to-day the growers of Cacti are not very numerous, and the demand for specimens not very pressing. M. pusilla was introduced from the West Indies in 1820, and a few others in the earlier years of the century; in 1827 a half-dozen Chilian species were introduced, and a number of Mexican species in 1835, including J. angularis, M. bicolor, M. eurrhifera, and M. haageana. M. Lehmann, M. sulcolanata, and M. rhodantha, other Mexican species, came in the following year, and the succession of new forms has been maintained since, some remarkable species being of quite recent date. Among these may be mentioned M. fisswrata (Mexico, 1885).

MAMILLARIA BICOLOR (two-coloured). Stem somewhat club-shaped, 8 or 10 inches high, 2 or 3 inches in diameter, branched near base; covered with dark green tubercles, which are partly hidden by the abundant close-set and spreading spines, which give the whole plant a cobwebby appearance. Flowers small, purple.

M. GRAcILis (slender). Stem cylindrical, not more than a couple of inches high, and half an inch thick. Tubercles small; spines white, spreading. Flowers large, pale yellow. Native of Mexico.

M. PECTINATA (comb-like). Stem conical, or more or less globular, 3 inches high ; tubercles short, with rosettes of white spines. Flowers yellow, 2 inches across, fading in about two hours after opening. Mexico.

M. PUSILLA (small), Stem globular, an inch high, with conical greyish tubercles, Spines white and brown. Flowers yellow, tinged with rose.

Some growers graft the more delicate species upon small rooted plants of Cereus. They are easily raised from seeds if these are sown on sandy soil, and placed in a sunny warm position, pricking off the seedlings as soon as they are large enough to handle. Most of the species develop offsets which may be removed and treated as cuttings. Description of Two species are figured—A, Mamillaria ‘pusilla, and Plate 116.

20URCe THISTLES Natural Order Cacrem. Genus Cereus

Cereus (Latin, wax, or pliant; in allusion to the wax-like fleshiness of the young shoots, or to the pliant stems of some species). A large genus (two hundred species) of succulent stove or greenhouse perennials whose soft flesh contains a woody core. The stems are mostly long and angular, studded with rosettes of spines. The flowers are large and showy, tubular in form, composed of a large number of sepals and petals, most of which are brightly coloured. The stamens also are very numer- ous, united to the walls of the tube. The style is thread-like, divided at the summit. The species are distributed chiefly throughout Central and South America and the West Indian Islands.

The genus Cereus has been represented in this country “exh for more than two hundred years, several species having been introduced in 1690: C. flagelliformis from Peru, C. hexagonus from Surinam, 0. lanuginosus and C. triangularis from the West Indies. Ten years later there came from Jamaica our first examples of C. grandiflorus. A few additional species turned up in the eighteenth century, beginning with C. tetragonus (1710) from South Armerica, and including C. heptagonus and C. repandus from the West Indies, C. peruvianus from Peru, and C. Royeni from South America—all in 1728. _ Several others were introduced towards the close of last century, but _ _ most of the species were unknown in our greenhouses until the present century, during which some of the finest have been introduced. Not many of these, however, may be easily obtained, and we content our- selves with describing a few species only.

PHyLLocactus (Greek, phyllon, a leaf, and Cactus) is a genus of about a dozen species, natives of Tropical America: shrubby epiphytes, generally clinging by means of their roots to the trunks of gigantic forest trees, and remarkable for their flat blade-like stems, the absence of true leaves, and for the large size and rich colours of their beautiful flowers. . They share with Epiphyllum the favour of cultivators in this country who do not care for Cacti generally. Many hybrids have been raised from them, and there are several hundreds of named varieties known. All are easily grown in light soil in a sunny position in a warm greenhouse, and often a success in room windows. They are easily multiplied by means of cuttings inserted in small pots in sandy soil or from seeds sown in spring.

described in being open and not tubular. The flowers are succeeded by pear-shaped or egg-shaped spiny fruits; those of some species being known as Prickly Pears, and greatly esteemed for their sweet, cooling, juicy pulp. The species are natives of the tropical and warm portions of America, but some have been introduced to and become naturalised in Southern Europe, the Canaries, and Northern Africa—hence its name of Barbary Fig.

Opuntia vulgaris, the hardiest of the tribe, and a native of Mexico, ete., was introduced from Southern Europe in that golden year from which we date so many horticultural novelties, 1596. Nearly a century passed by before another species was added to our green- houses; this was 0. cwrassavica from Curagoa in 1690. 0. ficus-indica from Mexico, and 0. Tuna, from the West Indies, were introduced in 1731, O. nigricans from South America in 1795, and many less popular species during the present century. 0. Z’wna, by reason of its prickly nature, is largely grown as a hedge-plant, as well as for rearing the valuable Cochineal insect. The same species, as well as 0. ficus-indica and O. decumana, is also much cultivated on account of its juicy fruits (Prickly Pears). From these fruits sugar and water-colours have been prepared, and from them the Mexicans make a beverage called Colinche.

O. Rarinesquii (Rafinesque’s). Plant spreading, 1 foot high; joints pear-shaped, flattened. Leaves spreading, a few small spines and a long one in some of the axils. Flowers yellow, often with red centre. Introduced from North America (1868).

O. Tuna (American-Spanish name). Stem 20 feet high in old plants; joints with tufts of four to six spreading yellow spines. Flowers dull reddish orange; July. Fruit pear-shaped, 2 or 3 inches long, rich carmine in colour and fleshy.

M. echinatum and M. tricolorum appeared fifty years later, and M. violacewm and M. cymbifolium in 1820 and 1822 respectively. Many less familiar forms came in between, and there has been a steady procession of new forms all through this century. J. edule is grown for its pleasant fruit. The leaves of M. pugioniforme are said to be a good substitute for Spinach, and those of M. tortuosum to be chewed as a narcotic by the Hottentots. M. cystallinwm is burnt in great quantities for the use of the glassmaker. A peculiarity of the seed-vessels must be noted. These shrivel up and imprison the seed, but on the approach of the rain that fits the ground for their germination, the vessel becomes plump and turgid. The seeds are thereby pressed out.

UMBELLIFEROUS FLOWERS Natural Order UMBELLIFERZ

This important Natural Order of plants, comprising one hundred and fifty-two genera and about thirieen hundred species, is singularly poor in garden flowers, though its contributions to the kitchen-garden are neither few nor unimportant. Most of those that appeal to the horti- culturist do so not on account of their flowers, but of their much-dissected and handsome foliage. Several species of Hryngium (allied to our native Sea-holly) are occasionally cultivated for the sake of their stiff glaucous leaves and heads of small blue flowers. <Astrantia major, the Black Masterwort, with pink and white flowers, is a showy border perennial. The Australasian genus TJ'rachymene contributes a single annual species, T. cerulea, with bright blue flowers. The genus Ferula is sometimes represented in beds bordering lawns by single specimens of F. communis, the Giant Fennel, whose finely divided foliage forms dense tufts, 3 or 4 feet high and wide, from which rise the flower-stems 3 feet higher. F. tingitana and F. glauca are also cultivated like F. communis as foliage plants. The genus Heraclewm, represented on our roadside wastes and hedge-banks by the Hogweed (H. sphondyliwm), includes several noble species that have been introduced to our shrubberies and wild-gardens from abroad. The most frequently seen is H. villoswm, or, as it is more generally but less correctly named, H. gigantewm. It grows to a height of 10 or 12 feet, but is quite out of place ina small garden, or indeed any place where it has not plenty of room to show itself. It is a native of the Caucasus.

A few other genera are occasionally represented in gardens, but on the whole the Order has very little interest for the gardener, though it has much for the botanist.

FATSIAS 245

FATSIAS Natural Order ARALIACEH. Genus Fatsia

Fartsta (the J apanese name). A small genus comprising only three species of shrubs with large, handsome, palmately-lobed leaves, and small greenish flowers arranged in umbels. Petals five, stamens five, stigmas five. The flowers are very similar to those of the Order UMBELLIFERA. The species are confined to North-West America, J. apan, and Formosa.

The Fatsias are of recent introduction to British gardens, F. horrida, from North-West America, making its appearance only in 1829 and F. papyrifera in 1852. The last named is rather tender in this country, and used chiefly in what is called sub- tropical gardening, but in its native country it has something more than horticultural value. It is the plant from which the Rice-paper is made. It is said to attain its full size in less than a year, when the stems are cut down and left to soak in running water for several days to loosen the bark. Then the cylindrical mass of pith is removed, cut into lengths, and revolved against the edge of a sharp knife, which cuts it into a thin even sheet. ;

FATSIA HORRIDA (rugged, in allusion to its spines and prickles). Stems 6 to 12 feet high, armed with yellow spines. Leaves palmately-lobed, the general outline being heart-shaped ; prickly. Flowers in terminal panicles of umbels; August.

F. saponica (Japanese). Stem erect, 3 to 5 feet. Leaves large and leathery ; digitately lobed. Flowers small, in umbellate panicles; July and August. There is a var. variegata with white margins and blotches; var. reticulata has golden-yellow veins, and var. variegata-awrea has markings of a rich yellow hue. Also known as Aralia Sieboldii.

F. PAPYRIFERA (paper-bearing). Rice-paper Plant. Stem erect, branching above, 6 to 8 feet high. Leaves large, five- or seven-lobed. Flowers in drooping panicles; July and August. Young plant downy, afterwards smooth.

Fatsias are chiefly grown in pots for greenhouse or indoor decoration; sometimes turned out in the beds in summer, ‘They succeed best in a compost of which sandy loam forms the base, and to which is added peat, leaf-mould, and sand. They require plenty of water, but free drainage must be provided. Propagation is effected by cuttings either of the root or stem, pieces about two inches long being inserted in pots of sandy soil and placed in bottom heat, when

a spent hot-bed, plunging the pots up to the rim in ashes or in the spent hot-bed (taking care that drainage is perfect), giving plenty of water,

and mulching the tops to protect the roots. The shoots should be

pinched back, and when the pots are well filled with roots liquid manure should be given. In potting a liberal quantity of crocks should be allowed, as efficient drainage is of the utmost importance; and the compost should consist of equal quantities of fibrous loam, sand, and leaf-mould, with the addition of a little peat.

Stopping the shoots should not be practised later than the end of August. As soon as the weather begins to turn cold they should be removed to the greenhouse, where they will do well through the winter in a temperature between 50° and 60°. They are propagated by means of cuttings taken from the new shoots, not necessarily at a joint, for they readily root from any part. The compost mentioned above, covered with a good layer of sand, should be used, the cuttings inserted rather closely in the pots, covered with a bell-glass, and placed in bottom heat. They require a close moist temperature of about 75°, and in this they will be rooted in about three weeks.

be kept both cooler and drier during the winter, otherwise they will not sufficiently ripen their wood. The most suitable soil is a compost of fibrous peat and leaf-mould, with a plentiful addition of silver sand. Although abundance of light is necessary for their successful growth, they must be protected from the direct rays of the sun in summer, Propagation is effected by means of short cuttings, inserted singly in pots of the compost named, and plunged in bottom heat, in a close and shaded frame; transferred to five-inch pots when rooted, and placed in the stove with a high temperature and kept moist.
