XXV. LEGUMINA‘CEE: CARACA NA. 237 
Varieties. 
a1 R.h. 2 nana Dec. is a plant hardly a foot high, found in pine woods 
in Carolina. 
% R. h. 3 rdsea Pursh has the leaflets for the most part alternate, and 
the branches smoothish. In its native habitats, on the high mountains 
of Virginia and Carolina, it grows, according to Pursh, to a con- 
siderable shrub, whereas the species is a low straggling plant. 
2% R, h. 4 macrophylla Dec., R. grandiflora Hort., figured in Arb. Brit., 
Ist 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 tor- 
tuous and very brittle branches, and leaves and flowers nearly twice the size 
of those of Robinia Psetd-Acacia. 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 parasol-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 the name of C. arboréscens among the Mongol Tartars. 
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 com- 
pressed, at length somewhat cylindrical and many-seeded, mucronate by the 
style. Sceds somewhat globose. (Don’s Mill.) 
Leaves compound, abruptly pinnate, alternate, stipulate, deciduous ; 
stipules usually spinescent. Flowers mostly yellow. 
Trees or shrubs, natives of Siberia and of the East. Leaves with the leaflets 
mucronate, and the petioles either with a bristly or a spiny point; their flowers 
axillary, each on a distinct pedicel, usually several together, pale yellow, 
except in C. jubata, in which they are white tinged with red ; their stipules 
usually become spines. They are all ornamental or curious, and of the easiest 
culture in any common soil ; propagated by cuttings of the roots or by seeds. 
The dwarf and pendulous-growing species, when grafted standard high on C. 
arboréscens, form very singular trees.
