Corolla purple-red, nearly as long as calyx; standard obcordate, base attenuate, long clawed; wings elliptic, shortly clawed; keel slightly falcate, longer than wings, curved, long clawed. Stamens diadelphous. Legume narrowly oblong, slightly falcate, flat, 5-12 x ca. 2.5 mm, lower suture undulate, upper suture straight, 3-5-jointed; articles nearly quadrate, with short, hooked hairs, reticulate veined"  (Flora of China online).

"Creeping herb; much-branched, somewhat mat-forming; leaves of 3 leaflets, the lower leaves sometimes unifoliolate; leaflets obovate, to obcordate, rounded and emarginate at tip, mostly less than 1 cm long, up to 9 mm wide, sometimes with 2 white marks; flowers few in fascicles, opposite leaves, pedicels 3-8 mm long, lengthening in fruit to just over 1 cm; puberulent; corolla reddish-violet or pale pink, standard obovate, 4-5 mm long; pods up to 17 mm long, about 2.3 mm broad, 3-7-jointed, indehiscent"  (Stone, 1970; p. 332).
