Characteristics

Virgate perennial herb or subshrub with a number of ascending stems to 60 cm tall, branched above, appressed pubescent to tomentellous. Leaves shortly petiolate, 3-foliolate; leaflets narrowly oblong-elliptic to elliptic or oblanceolate to obovate, mostly 8-25 x 3-10 mm, appressed pubescent to sericeous at least beneath. Stipules narrow, variously developed. Racemes mostly well developed, with a number of flowers laxly to rather closely arranged towards the top; bracts linear to linear-lanceolate, 2-6 mm long; bracteoles on upper part of the pedicel, filiform, small. Calyx 6-7 mm long, appressed pubescent; lobes narrowly attenuate-triangular, longer than the tube. Standard elliptic or elliptic-obovate, yellow, glabrous or with small scattered hairs near the apex outside; wings a little shorter than the keel; keel strongly rounded and crested behind the small beak, 7.5-8.5 mm long. Legume shortly stipitate, obliquely obovoid to oblong-ellipsoid, ±8-11 mm long, sericeous, 2-4-seeded. Seeds oblique-cordiform, ±3.5 mm long, smooth, brown.
