The legume in all the species of the genus we have seen, is, unless when 
very old, more or less pubescent ; and we, therefore, place no dependence on 
that as a character: we have seen so many intermediate forms between our two 
varieties, that we ought perhaps to have united them. R. microphylla, Heyne 
in Wall. L. n. 5497, appears to be this species grown in a more arid soil ; 
and R. ternuicaulis, Wall. L. n. 5495, seems merely a more luxuriant form 
with longer racemes than usual. We suspect there are very few good a" 
cies in the whole genus; nor are we able to point out any satisfactory cha- 
racter by which to distinguish some of the West Indian species, and one be- 
ore us from Juan Fernandez, from the present. 
5. Bracteas oblong-lanceolate, longer than the pedicel, thin-foliaceous, somewhat 
rmanent: calyx-segments longer than the corolla: legume oblong, a little 
onger than the calyx. 
734. (4) R. densiflora (DC.:) twining, all over pubescent except the co- 
rolla: leaves trifoliolate ; leaflets softly pubescent on both sides, dotted co- 
piously on the under and sparingly on the upper with minute brownish resi- 
nous glands, acute or slightly acuminated, lateral ones obliquely broad-ovate, 
terminal rhomboid : racemes axillary, almost sessile, bracteated, short, dense, 
many-flowered ; bracteas oblong-lanceolate, acuminated, a little shorter than 
the calyx, and with the calyx sparingly villous and dotted: calyx-segments 
narrow-lanceolate, subulate, longer than the glabrous corolla : legume oblique- 
ly-oblong, shortly pointed, 2-seeded, dotted, pubescent and villous.—DC.

Subgen. 2. PHYLLOMATIA. Calyx cleft to near the base: segments almost 
equal, oval-oblong, obtuse, foliaceous, about the length of the corolla. Keel 
faleate, Ovary 1-2-ovuled. Legume sessile, a little longer than the calyx, 
slightly compressed, obliquely roundish-oval or oblong, shortly pointed, 
l-2-seeded. Seeds with a large bifid fleshy carunculus. 
735. (5) R. (Ph.) rufescens (DC.:) diffuse or scarcely twining, densely 
haat fonts Sextet aded, prominently reticulated under- 
neath with the nerves and veins: racemes slender, usually elongated, few-

nearly as long as the legume, elliptic-oblong, obtuse: legume lens-shaped, 
Short-pointed, 1-seeded, pubescent.—DC. prod. 2. p. 887; Wight! cat. n.
