Stems ridged, densely pubescent, tomentose or strigillose (sometimes also villous-hirsute with scattered longer hairs), hairs ferrugineous or whitish; becoming terete, reddish-brown to grey, longitidinally striate, fissured, lenticellate below. Stipules 4-13 mm long, lanceolate to linear-attenuate or filiform, ± spreading or falcate-recurved. Leaves pinnately (11)13-25-foliolate; leaf axis 3-12 cm long, including petiole of 5-14 mm, extended 1-7 mm beyond lateral leaflets; stipels 0.5-1.5 mm long, filiform; terminal leaflet 6-20 x 4-10 mm, broadly obovate or elliptic, apex obtuse, rounded or truncate; laterals longer, oblong-elliptic to ovate; leaflets either sparsely to densely silky pubescent or tomentose on both surfaces (weak spreading hairs mostly unequally biramous to subsimple), or strigose to strigillose with appressed ± equally biramous hairs, hairs diverging at 20-45° from midrib; ± coriaceous, margins often retuse. Raceme 5-14 cm long, including peduncle of 16-60 mm, densely (15)20-60(80)-flowered; bracts 2-6 mm, lanceolate-attenuate or subulate; pedicels 2-4 mm long. Calyx 1.5-3 mm long, densely silky pubescent to tomentose with whitish or ferrugineous hairs; lobes lanceolate-subulate, ± equal to tube. Corolla 7-9 mm long, reddish-purple or deep crimson, rounded at apex in bud, drying purplish, back of standard indumentum whitish or ferrugineous pubescent. Stamens 6-7 mm long. Style 2-3.5 mm long, curving erect from a thickened style-base, becoming a slightly upturned beak in pod. Pod (19)24-34 x 2.5-4 mm, cylindrical, glabrous, spreading to reflexed.
