Rootstock long, branched, covered with castaneous-brown bark, branches ligneous, densely appressed white hairy. Stems of the current year 6–13 cm, often branched at the base, densely to very densely covered with white, sometimes at the nodes also with black hairs 0.8–1 mm. Stipules narrowly triangular, acuminate, 5–8 mm, adnate to the petiole for c. 2 mm, densely covered with white and often, especially near the base, also black hairy, sometimes soon glabrescent. Leaves 3–7 cm; petiole 0.7–1.2 cm, like the rachis loosely to rather densely hairy like the stem. Leaflets in 3–4 pairs, narrowly elliptic to narrowly obovate, 10–35 × 4–10(–12) mm, acute, on upper side sparsely hairy or nearly glabrous, on underside sparsely to loosely covered with strongly appressed hairs 0.8–1.5 mm. Peduncles 3–5 cm, sparsely white hairy to partly subglabrous. Racemes subglobose, 3–5 cm in diameter, 4–8-flowered. Bracts narrowly triangular, 4–7 mm, white and black hairy. Calyx at anthesis c. 12 mm, tubular, rather densely covered with basifixed to subbasifixed, spreading white hairs 1–1.5 mm and with strongly asymmetrically bifurcate, shorter, mostly subappressed to ascending black hairs; teeth subulate, 2.5–3 mm; calyx at fruiting time ovoid-inflated, 15–18 mm. Petals yellow. Standard 20–26 mm; blade 8–10 mm wide, obovate, widely retuse, at the base angularly passing into the short claw. Wings 18–23 mm; blades narrowly oblong, slightly retuse, 8–9 × 2–3 mm; auricle c. 0.6 mm, claw 13–15 mm. Keel 18–22 mm; blades obliquely elliptic, with widely curved lower edge ande sigmoid upper edge, obtuse, 7–8 × 3 mm; auricle acute, minute, claw 13–15 mm. Stamen-tube truncate at the mouth. Ovary sessile, narrowly oblong, white hairy; style hairy in lower third. Legumes sessile, narrowly oblong, 12–14 mm long, c. 3.5 mm high, keeled ventrally, scarcely grooved dorsally, abruptly attenuate into a beak 1–1.5 mm, bilocular; valves coriaceous, villous with spreading white and golden hairs, at the tip and sometimes also on the ventral side with shorter black hairs mixed in.
