p. 338.; Don's Mill., 3. p. 451. Derivation. Named by Dr. Wallich after his friend William Leycester, formerly chief judge of the principal native court under the Bengal Presidency; "who, during a long series of years, and in various parts of Hindoostan, has pursued every branch of horticulture with a munificence, zeal, and success, which abundantly entitle him to that distinction."
Description, &c. This genus appears to be intermediate between Caprifoliàceæ, and Rubiàceæ; but from the last it is distinguished by the want of stipules. (Don's Mill., iii. p. 451.) The only species known is a shrub, a native of the Himalayas.

827 bling, deciduous shrub, a native of the highest mountains which surround the valley of Nepal ; and of much more northerly situations, towards Gossainthan, at elevations of between 6000 ft. and 7000 ft., and even as high as 8000 ft., among forests of pine and oak. It is a most beautiful shrub when in a flowering state, from the contrast of the deep green hue of its stem and leaves, with the purple colour of its large bracteas and its berries. It was introduced into British gardens in 1824, and it flowered soon afterwards in the nursery of Messrs. Allen and Rogers, at Battersea, whence specimens were sent to the late Mr. Sweet, and to Mr. G. Don.
It is a rambling shrub, with the general appearance of a honeysuckle ; and it will probably prove somewhat tender in this country; but, as it is easily propagated by cuttings, or by seeds, which it produces in abundance, a stock of plants might easily be kept in readiness to provide for accidental losses. Trained against a conservative wall, it would have a splendid effect in autumn . There are young plants, raised in 1836, from Nepal seeds, in the Horticultural Society's Garden
OF THE HARDY LIGNEOUS PLANTS OF THE ORDER RUBIACEÆ.

A shrub, growing to the height of from 6 ft. to 8 ft. ; a native of North America, from Canada to Florida, in marshy places. It was introduced in 1735, and Alowers in July and August. It will grow in common garden soil, but prefers peat kept moist; and is propagated chiefly by seeds, but will also grow by cuttings and layers. It is an inter
esting shrub, from its curious round heads of flowers, and from the lateness of the season at which these appear. Price of plants, in the London nur

was collected by Berlandier. (Don's Mill., iii. p. 610.) Some other species of Cephalánthus are described in De Candolle's Prodromus and Don's Miller ; but they are natives of South America, the East Indies, or China, and are considered as requiring the green-house or the stove.
Half-hardy ligneous Plants belonging to the Order
Pincknèya pùbens Michx. (North Amer. Syl., 1. p. 260. t. 49.) and our fig. 830.), Pincknèya pubescens Pers., Cinchona caroliniana Poir., is a tree growing to the height of 20 ft., in Georgia, South Carolina, and other parts of North America. The branches and leaves are tomentose, and the flowers rather large, pubescent, and white, tinged with red. The tree divides into numerous branches, and is covered with large light green leaves, which are downy beneath, but it is not particularly ornamental. In America it is called Georgia bark, and was originally supposed to belong to the same genus as the cinchona, which it strongly resembles. It is interesting for the properties of its bark; which partakes of the same bitter qualities as that of the cinchona ; and which is employed successfully in the alleviation of the intermittent fevers which prevail in the country where it is a native. The wood is soft, and unfit for use in the arts. In England, the plant is generally kept in green-houses or cold-pits; but it will
830 thrive much better if planted in the free ground, and trained against a wall with a southern exposure. It requires a shady situation, and is said to thrive best in a mixture of sand and peat.

with a fig:; Dysoda fæ'tída Salisb. Prod., p. 60.; Sperma, coce fruticosa Desf. Hort. Par. ; is a native of China, Japan, and other parts of the East, where it forms a bushy shrub, growing to the height of 2 ft. or 3 ft., with small, dark green, shining leaves, a little deflexed; and flowers which are white within, and reddish without, and often single and double on the same plant. In Japan, it is frequently planted for hedges. It was introduced in 1787, and grows freely in our green-houses, in a mixture of loam, peat, and sand, flowering during the most part of the summer.
Plócama péndula Ait. ; Bartlingia scoparia Rchb. Icon. Erot., t. 11. į is a small, glabrous, much branched shrub, with the branches round, slender, and pendulous, and the leaves linear, filiform, and opposite. It is a native of the Canary Islands, where it grows to the height of 2 ft.; and was introduced in 1779, but has not yet flowered. Phyllis Nobla L. (Dill. Elth., p. 405. t. 299. f. 386.) has been an
831 + inhabitant of our green houses since 1699. It is a glabrous shrub, with round branches, and small greenish white flowers, which are produced in June and July
Anthospermum æthiópicum L. ; Ambraria Heisteri Walth. Hort., t. 9., Hort. Cliff., t. 27., Pluk. Alm., t. 193. f. 1. ; is a branched shrub, with small linear leaves, shining above, and whitish beneath. The male and female flowers are produced on different plants, the former being brownish, and the latter green. This is an evergreen Cape shrub, an old inhabitant of our green-houses, where it forms a dense fastigiate bush, sometimes as high as 4'it., and Aowering in June and July. it well deserves a place against the conservative wa)).
Rùbia fruticosa Ait., Don's Mill., 3. p. 643., Jacq. Icon. Rar., t. 25. ; R. fruticosa canadensis Poir.; is a native of the Canary Islands, where it grows to the height of 4 ft. or 5 ft., and produces its small yellowish flowers in September. It is chiefly remarkable for its leaves, which are from 2 to 6 in a whorl; and, as it is somewhat shrubby, it deserves a place against a conservative wall, or on dry rockwork
Bouvárdia Jacquini H. B. et Kunth Don's Mill., 3. p. 486.; B. triphylla Hort. ; Houstdnia coccínea Bot. Rep., t. 106. ; is a native of Spain, growing to the height of 2 ft. or 3 ft., with scarlet tubular flowers, with a tube about 9 lines long, which appear from April to November. It is a most desirable shrub, for turning out into beds and borders during the summer season, or for training against a low conservative wall. There are two forms of it in British collections, one with leaves much more pubescent than those of the other.
Manettia glabra Cham. et Schlect., Swt. Fl. Gard., 2d ser., t. 334. ; M. cordifolia Mart., Hook. Bot. Mag., t. 3202., Gard. Mag., ix. p. 107., and x. 238.; is an exceedingly elegant little twiner, with scarlet tubular corollas, and broad deep green leaves. It is a native of Buenos Ayres; and, Professor D. Don observes, will doubtless succeed well in the open border during summer.

HALF-HARDY PLANTS BELONGING TO THE ORDER CAMPANULACEÆ.
Mussckia aurea Dumort. ; Campánula aurea L., N. Du Ham., 3. p. 169., Bot. Reg., t. 57. ; is an evergreen suffruticose plant, growing to the height of 2 ft. or more, in Madeira and Teneriffe, among rocks. It is an interesting shrub, which may be compared to a miniature tree. The stem is simple, rather fleshy, marked by the scars left by the falling of the leaves, but furnished with a crown of leaves at top, and annual floriferous branches, which are disposei in a leafy pyramidal panicle. Leaves 3-6 in. long, pale green, shining. Peduncles 13.flowered,
Flowers erect. (Don's Mill., iii. p 772.) From the habit of this plant, it is better adapted for conservative rockwork, than for being trained to a wall; but it may be tried in both manners; for, as it ripens seeds freely, the loss of plants can easily be supplied.
