An undershrub 20 to 60 cm high, erect or slightly scandent, the stem 
grayish or brownish, 3 to 4 mm in diameter, glabrous, smooth, simple, or 
very rarely with one or two branches, the younger parts densely puber- 
ulent. Leaves trifoliolate, the common petiole and rachis 5 to 10 cm 
long; stipules lanceolate, acuminate, 5 to 7 mm long, striate, puberulent; 
stipels acicular, puberulent, 3 to 5 mm long ; leaflets subrhomboid, oblong- 
ovate to elliptic-ovate, chartaceous or submembranaceous, glabrous on the 
upper surface, the lower somewhat puberulent on the veins and reticula- 
tions, the apex rather strongly subcaudate acuminate, the base triangular- 
acute, the terminal leaflet equilateral 9 to 20 cm long, 5 to 7.5 cm wide, 
the lateral ones one-half to two-thirds as large, and somewhat inequi- 
lateral at the base, the rachis prolonged 1 to 3 cm beyond the insertion 
of the lateral leaflets; nerves prominent on the lower surface, a pair 
of opposite or alternate ones leaving the midrib at 5 to 10 mm above 
the base and extending to or above the middle of the leaflet, the lateral 
nerves above the subbasal pair 4 or 5 on each side of the midrib, curved- 
ascending, ultimately anastomosing, the reticulations distinct, rather 
lax; petiolules puberulent, 2 to 4 mm long. Inflorescence terminal, of 
simple racemes, or rarely forming a 2- or 3-branched panicle, 10 to 
20 cm long, puberulent. Flowers white, about 7 mm long, in pairs, the 
bracteoles ovate-lanceolate, strongly acuminate, 1.5 mm long, the pedicels 
about 2 mm long. Calyx 3 mm long, puberulent, 2-cleft, the upper lobe 
with two minute teeth, the lower divided into three ovate-lanceolate, 
strongly caudate-acuminate, 1.5 mm long teeth. Standard orbicular- 
obovate, about 6 mm long, 5 mm wide, rounded, base narrowed to the 
short claw; wings about 2 mm wide, united to the keel. Yexillary 
filament free throughout. Ovary stipitate, lanceolate, narrowed at both 
ends, viscid-puberulent, with a single ovule. Pod not articulated, com- 
pressed, lanceolate-acinaciform, narrowed at both ends, stipitate, the 
apex prominently acuminate, somewhat falcate or nearly straight, the 
upper suture usually straight, the lower curved, scahrous-puberulent, 
indehiscent, strongly reticulate, the pericarp coriaceous, 2 to 3 cm long, 
4 to 5 mm wide. Seed solitary, brown, glabrous, narrowly oblong,
