Robinia, in memory of Jean Robin, herbarist to Henry IV., of France.

A North American genus of a few species of trees or shrubs, bearing a profusion of handsome, pea-shaped flowers, in long, pendent racemes, and elegant compound leaves.

Robinia pseaudacacia. - The Common Locust. - This is too well known to make it necessary to give a description.

Were it not forthe ravages of a species of borer, which at tacks this tree, oftentimes destroying them in a few years, it would be one of the finest in existence for the back-ground of a shrubbery. It is a rapid grower, elegant foliage, fragrant, beautiful flowers, in great profusion, and very hardy. The blossoms are butterfly or pea-shaped, white, with yellow in the middle, produced in June and July. The insects are so destructive to it, that the trees soon become disfigured, losing their limbs, in consequence of the many perforations made by these troublesome little creatures.

Robinia viscosa. - Clammy-barked Locust. - This is a small tree, with large pale-pink flowers. The branches are covered with a gummy substance that is unpleasant to the touch. It looks well with other trees and shrubs.

Robinia hispida. - Rose Acacia. - This is a beautiful flowering shrub, growing from three to ten feet high,bearing a great profusion of elegant rose-colored flowers, which are produced in dense, pendent racemes. The shrub commences flowering when only two feet high. It has long, rambling roots, which throw up numerous suckers. The branches are thickly clothed with stiff hairs. This is a very desirable species. The foliage resembles the other species.

Robinia crispa. - Crisp-leaved Robina. - This is a species or variety we imported last year, with others named below. It has very singularly curious and elegant leaves; they are compound, like all the others, each leaflet being curiously and uniformly contorted, giving to the foliage a very unique and rich appearance. The others were R. inermis; tertuoso, the branches all growing in a circular, zigzag style; mac~ rophylla, sophorafolia, ibia, volubilis, elcgans and grandi-flora. The style of the leaves in all is the same; only a few of them flowered, but all will be desirable, no doubt, for ornament, if they are not disturbed by the borers.

The new sorts are propagated by grafting on the common varieties.
