Ascending and spreading annual, much branched from the base, with the lower branches mostly long and decumbent, sometimes to 0.6(-l) m tall, usually much smaller; branches covered, often thinly, with rather long hispid spreading hairs. Leaves 3-foliolate; leaflets linear-lanceolate to lanceolate or oblanceolate, with the lower ones sometimes elliptic or obovate, mostly 1.5-7 x 0.4-1.7 cm, thinly appressed pilose beneath; petiole shorter than the leaflets. Stipules subulate to linear-lanceolate, caudate, 3-9 mm long. Racemes up to 8-16(-25) cm long, long and slenderly pedunculate, with few to many laxly arranged flowers; bracts subulate, 1-2 mm long; bracteoles usually inserted at the base of the calyx, less than 1 mm long. Calyx 3-4 (-4.5) mm long, subglabrous to appressed pubescent; lobes acuminately triangular, at least slightly longer than the tube. Standard subcircular, yellow, reddish brown veined outside; wings shorter than the keel to ± as long; keel rounded below the middle, with a short straight or less commonly incurved beak, 5-7(-9) mm long. Legume sessile, subglobose-ellipsoid to broadly ellipsoid to rarely oblong-ellipsoid, 1-1.3(-1.7) x (0.6-) 0.7-0.8 cm, usually mottled brown, puberulous, ±20-24-seeded. Seeds oblique-cordiform, 2.5-3 mm long, often slightly rugulose, reddish brown.
