Leaves 2-5 cm; stipules 1-2 mm, shortly adnate to petiole, hairy; petiole 0.5-1.5 cm, with rachis slender, loosely to densely hairy like stem; leaflets in 5-7 pairs, narrowly elliptic, 4-11 × 0.5-2 mm, both surfaces loosely to densely covered with white hairs. Racemes capitate-umbellate, 4-8(-10)-flow­ered; peduncle 5-10 cm, loosely to densely hairy like stem; bracts 1-1.5 mm, white and black hairy. Calyx 8-10 mm, densely covered with ± asymmetrically bifurcate, subappressed, white hairs 0.5-0.8 mm (predominantly adaxially) and with more symmetrically bifurcate, shorter, black hairs (predomi­nantly abaxially); teeth 0.5-1.5 mm. Petals lilac; standard obo­vate, 20-22 × ca. 8 mm, apex emarginate; wings 18-20 mm; keel 16-18 mm. Legumes shortly stipitate, erect to obliquely erect or spreading, straight, 20-35 mm, 1.5-2 mm high, ca. 1 mm wide, with a straight, slender beak 1-2 mm; valves rather densely covered with appressed to subappressed, asymmetri­cally bifurcate, white hairs ca. 1 mm and with more symmetri­cally bifurcate, shorter, black hairs.
