Root somewhat cylindrically tuberous, perennial. Stem herbaceous, pros- 
trate, branching in every direction, about 2 feet, long, glabrous. Leave s 
digitate, generally by fours, leaflets lanceolate, very acute, the lower one 
sometimes obovate, all entire, glabrous and dotted; common petiole 1 — 2 
inches long, partial petioles scarcely one line long. Stipules lanceolate, 
very acute, deciduous. Flowers in long (4 — 8 inches) simple, axillary 
spikes, somewhat distichous on the spike. Bracteas 2 at the base of each, 
flower, covering the bud and nearly enclosing the expanded flower, lan- 
ceolate, ciliate, acuminate, attached to the stem near its summit. Calyx 
4 cleft, the upper segment broad, emarginate, all fringed. Corolla yel- 
low, the vexillum and keel longer than the wings. Siemens monadelphous, 
the stameniferous tube divided to the middle, the segments alternately 
longer. Anthers 5 round, 5 oblong. Lomentum 2 — 4 jointed, joints 
nearly round, rugose and hispid. In its artificial character this plant is 
very nearly allied to the genus Hedysarum, where it was formerly placed. 
In habit it is very distinct.
