$ 0. f. 2 microphylla Dec., 0. fruticòsa Asso.- Leaf-

lets small, obovate, and serrated. (Dec.) The
species is a native of sunny places in the Alps
of Gallo-provincia, Dauphiné, &c.; the variety of
the mountains of Aragon. (Dec. Prod., ii. p.161.)
Introduced in 1680. A shrub not unfrequent
in botanic gardens, and sometimes growing to
the height of 4 ft. It is, perhaps, the only species
worth planting in an arboretum. It produces
its purplish red flowers in May and June. There
is something remarkably singular and attractive
in all the shrubby species of the genus Ononis ;
and this variety certainly belongs to one of those
species which are most deserving of cultivation,
Under favourable circumstances it has exceeded
6 ft. in height, flowering abundantly. Price of
plants, in London, Is. 6d. each.

300 plain yellow, the other with the standard yellow, streaked with red : the last is the 0. pinguis of Lin. Sp., 1009., and of our Hortus Britan. nicus, No. 17561. This species seldom exceeds 18 in, in height in a wild state, or 2 it. in a state of culture. In British gardens, this species is very commonly introduced in collections as a herbaceous plant; and very properly so, because, practically speaking, all plants technically ligneous, which do not, in a state of cultivation, exceed the height of 18t. or 2 r., may with propriety be called in to increase the number of spe. cies which

can be planted together and treated as herbs. It would surely be ridiculous to omit from herbaceous collections thyme, hyssop, sage, germander, lavender, rosemary, rue, wormwood, southernwood, iberis, alyssum, mitchella, the British heaths, and a great many others that might be mentioned, merely

because, not dying down to the ground every year, they are considered by botanists as shrubs, and consequently fit for introduction into an arboretum.

App. i. Olher suffruticose Species of Onònis. 0. pedunculàris Lindl. (But. Reg., t. 1446., and our fig. 301.) is a small shrub, not more than a foot high, introduced in 1829, from Teneriffe, with fragrant white and rose-coloured flowers. It is usually kept in a frame. It would do, with a little protection, for rockwork. It is in Messrs. Young and Penny's collection.

O. crispa L., O. hispánica, 0. vaginalis L., O. arachnoidea La. peyr., o. longifolia Willd., o. falcàta Willd., 6. ramosissima Desf., Ó. tridentàta L., 0. angustifolia Lam., and o. fatida Schousb., are other species of Ononis varying in height from 1 ft. to 3ft., and usually kept in frames or cold-pits; but which, if protected in severe weather, would be very ornamental for rockwork. Descriptions of them will be found in our Hortus Britannicus, and in Don's Miller.

Other species of Ononis marked in catalogues as herbaceous, are nearly as suffruticose as those last mentioned; and, where the object is to extend a collection, there are several that may be introduced in the arboretum. Indeed it may be safely assumed that, where several species of a genus are ligneous or suffruticose, all the species of that genus are more or less so, and may, by culture, be prevented from dying down to the ground during winter; provided that genus has been formed on natural principles.

Description. Large deciduous shrubs, natives of North America. Leaves impari-pinnate, having many pairs of leaflets that have transparent dots in their disks, and, usually, minute stipules at their base. The leaves have deciduous stipules. The flowers are disposed in lengthened spiked racemes, usually grouped at the tips of the branches; of a blue-violet colour. (Dec. Prod., ïi. p. 256.) The species are highly ornamental on account of their

. leaves, and more especially of their long spikes of flowers; which, though, when taken separately, they are small, and imperfect in regard to form, are yet rich from their number, and their colours of purple or violet, spangled with a golden yellow. The plants are not of long duration; and are liable to be broken by wind; for which reason they ought always to be planted in a sheltered situation. They produce abundance of suckers, from which, and from cuttings of the root, they are very readily propagated. The several sorts that are in the garden of the London Horticultural Society, and in the arboretum of the Messrs. Loddiges, appear to us only varieties of one and the same species.

grows to the height of from 9 ft. to 12 ft. In Britain, it produces its long close spikes of fine, rich, very dark, bluish-purple flowers in June and July. It was introduced into Britain in 1724, by Mark Catesby; who states that the inhabitants of Carolina, at one time, made a sort of coarse indigo from the young shoots. It is now a common shrub in Eu. ropean gardens; and Thunberg is said to have observed it in those of the

Island of Nipon, in Japan.

A native of Louisiana, on the banks of the Missouri and the Mississippi; producing its dark blue flowers in July and August. Introduced in 1812, by Lyon, but not common in col. lections. This sort, like every other kind of Amorpha (and indeed like all ligneous plants, the wood of which is not hard and compact, and the duration of which is consequently but temporary), requires to be well cut in every year, or otherwise to be planted in very poor, dry, sandy soil. Nothing but cutting in shrubs of this description in soils where they grow freely, will either make them assume handsome shapes, or preserve their vitality for any length of time. The same may be said of the peach, the almond, the hydrangea, the ribes, and many other soft-wooded trees and shrubs.



ROBI'NIA Lin. The Robinia, or LocusT TREE. Lin. Syst. Diadelphia

Decándria. Identification. Dec. Mém. Lég, 6.; Prod., 2. p. 261. ; Don's Mill., 2. p. 237. Synonymes. Pseudacàcia Tourn. Insl., t. 417. ; Moench Meth., 145.; Robinier, Fr.; Robinie, Ger. Derivation. Named in honour of Jean Robin, a French botanist, once herbalist to Henry IV. of

France, author of Histoire des Plantes, 12 mo, Paris, 1620; printed with the second edition of Lonicer's History of Plants. His son Vespasian was sub-demonstrator at the Jardin des Plantes in Paris, and was the first person who cultivated the Robinia Pseud-Acàcia in Europe.

Description. Deciduous trees, natives of North America, where one of the species is highly valued for its timber. In Europe, all the species are much prized both for their use and beauty. They are readily propagated by seeds, large truncheons of the stem and branches, cuttings of the roots, or by grafting; and they will grow in any soil that is not too wet. Their roois are creeping, and their branches very brittle : they grow rapidly, but are not generally of long duration, Their rapid growth is a property that they have in common with all trees and plants the principal roots of which extend themselves close under the surface; because there the soil is always richest : but the same cause that produces this rapidity at first, occasions the tree to grow slowly afterwards, unless the roots are allowed ample space on every side; since, as they never penetrate deep, they soon exhaust all the soil within their reach. For this reason, also, such trees are objectionable as hedgerow trees, or as scattered groups in arable lands; their roots proving a serious impediment to the plough, and the suckers thrown up by them choking the corn crops. Roots, on the other hand, which penetrate perpendicularly as well as horizontally, belong to more slowly, but more steadily, growing trees, which always attain a larger size in proportion to the extent of ground they occupy.

Tree, Amer.; the Bastard Acacia; Robinier faux Acacia, Acacia blanc, Carouge des Américains,

(Acàcia vera), from its prickly branches and pinnated leaves, which resembled those of that tree. It was named the locust tree by the missionaries, who were some of the first collectors, and who fancied that it was the tree that supported St. John in the wilderness. It is not, however, a native of any other part of the world than North America. The name Carouge, is the French word for carob hean, the locust tree of Spain ; which, being also a native of Syria, is, probably, the true locust of the New Testament. f'be German name of Schotendorn is composed of schote, a pod, or le.
