Erect branched shrub or subshrubby herb, rarely a small tree, 0.9-3.6(4.5) m tall. Stems leafy, densely pubescent or hirsute. Leaflets 3, 2.5-11(12) x 1-5(7) cm, oblong-elliptic or ovate-elliptic to oblong-lanceolate, acute to acuminate, rounded to truncate at the base, pubescent to villous above, pilose on the venation beneath; venation impressed above, strongly raised beneath so that the leaflet is often conspicuously rugose but this varies greatly; petiole 0.5-6(12) cm long; rhachis 1-15(20) mm long; petiolules 2-3 mm long; stipules reflexed, c. 8-15 x 5-7 mm, oblong, pubescent. Inflorescences terminal; rhachis 2-6(19) cm long; peduncle 2(6) cm long; pedicels 2-3 mm long; bracts large, soon deciduous, comose at the apex of the inflorescence, 8-20 x 4-14 mm, round to ovate, acuminate to cuspidate at the apex, appressed silvery pubescent. Calyx silvery to ferruginous, pubescent or pilose and with longer tubercular based yellowish hairs; tube 3-4 mm long; lobes 7-27 x 2-5 mm, lanceolate, the lowest usually the longest, the upper pair joined for ± half their length. Standard bright yellow veined with brownish-red, 1.5-2 x 1.2-1.4 cm, glabrous. Pods 17-20 x 7-8 mm, oblong, acuminate, densely clothed with yellow tubercular based bristly hairs and also some finer pubescence. Seeds dark blackish-red, 4 x 3 x 1.5 mm, reniform, compressed.
