J* R. h. 2 nana Dec. is a plant hardly a foot high, found in pine woods
in Carolina.

of Virginia and Carolina, it grows, according to Pursh, to a considerable
shrub , whereas the species is a low straggling plant.

1st edit., vol. V . , has the leaflets large, and ovate-roundish; and the
branches and peduncles glabrous, and without prickles.
The species, and the different varieties, are shrubs or low trees, with tortuous
and very brittle branches, and leaves and flowers nearly twice the size
o f those o f Robinia Pseùd-ricàcia. They form singularly ornamental shrubs
for gardens ; but, as standards or bushes, they can be only planted with safety
in the most sheltered situations. When grafted standard high, and trained to
a wire pai-asol-like frame, supported on a rod or post 6 or 8 feet high, few
plants are equal to R . h. macrophylla in point of brilliant display.

Derivation. Caragan is th e name of C. arborescens among th e Mongol T a rta rs .
Gen. Char. Calyx short, tubulous, 5-toothed. Corolla obtuse, straight ; the
wings and vexillum about equal in length. Stamens diadelphous. Style
glabrous. Stigma terminal, truncate. Legume sessile, young ones compressed,
a t length somewhat cylindrical and many-seeded, mucronate by the
style. Seeds somewhat globose. (Don’s Mill.)
Leaves compound, abruptly pinnate, alternate, stipulate, deciduous ;
stipules usually spinescent. Flowers mostly yellow.
Trees or shrubs, natives o f Siberia and of the E a s t. Leaves with the leaflet!'
mucronate, and the petioles either with a bristly or a spiny p o in t; their flowers
axillary, each on a distinct pedicel, usually several together, pale yellow,
except in C. jubàta, in which they are white tinged with red ; their stipules
usually become spines. They are all ornamental or curious, and o f the easiest
culture in any common soil ; propagated by cuttings o f the roots or by seeds.
The dwarf and pendulous-growing species, when grafted standard high on C.
arboréscens, form very singular trees.
