Rootstock with a pluricipital root-crown, with numerous, short, ligneous subterranean stolons. Stems of the current year 0.5−4 cm, densely covered with appressed, medifixed, white hairs 1–1.2 mm. Stipules membranous, 3−5 mm, shortly adnate to the petiole, those of loser leaves connate hifg up, those of upper leaves shortly connate, covered with white hairs, with some black hairs mixed in. Leaves 3−7(−10) cm; petiole 1.5–4 cm, slender, with the rachis loosely to densely hairy like the stem. Leaflets in 2−4(–6) pairs, narrowly obovate to narrowly elliptic, 5−11 × 1.5−3(–4) mm, acute to subobtuse, on both sides rather densely to densely covered with appressed, medifixed hairs c. 1 mm. Peduncles 3–6 cm, white hairy. Racemes subumbellate, loosely 2−5-flowered. Bracts membranous, (1–)2−3.5 mm, narrowly ovate, acuminate, white hairy. Pedicels 1−1.5 mm, white hairy. Calyx 9−12 mm, tubular to campanulate-tubular, with appressed. ± medifixed, white or white and black hairs 0.8–1 mm; teeth subulate, c. 3 mm. Petals pale yellowish or white, keel violet-tipped. Standard 18−24 (–28) mm; blade 8−10 mm wide, obovate, retuse, at the base gradually narrowed. Wings 15−20 (–23) mm; blades narrowly oblong, obliquely retuse, ± as long as the claw. Keel 13−18(−20) mm. Ovary with a stipe c. 2 mm, white hairy. Legumes with a stipe 1−2 mm, narrowly oblong, straight to slightly curved, 18−23 mm long, 4−5 mm high, 2−2.5 mm wide, compressed laterally, keeled ventrally, narrowly grooved dorsally, bilocular; valves coriaceous, densely covered with asymmetrically bifurcate, ascending, flexuose, tangled white hairs up to 2 mm. Chromosome number 2n = 32 (KNJASEV, M.S., KULIKOV, P.V. & PHILIPPOV, E.G., l.c.).
