Rootstock with a pluricipital root-crown.. Stems several to many, branched at the base, ascending to erect, slender, 6–15 cm, terete, rather densely hairy. Stipules c. 2 mm, triangular, shortly connate behind the stem, sparsely hairy. Leaves 2–4 cm; petiole 1–1.5 cm, with the rachis hairy. Leaflets in 5–9 pairs, elliptic to narrowly elliptic, (3–)7–13 × (1.2–)1.5–8 mm, rounded to widely retuse or emarginate, on upper side sparsely hairy to subglabrous, on underside rather densely hairy, sometimes densely hairy on both sides. Peduncles 2–4 cm, slender, rather densely hairy. Racemes loosely to rather densely 5–20- flowered. Bracts brownish-membranous, narrowly triangular, 0.5–1(–2) mm, with white and sometimes few black hairs, at the margins with subbasifixed hairs. Pedicels c. 1.5 mm, white hairy. Calyx turbinate-campanulate, 3–5 mm, slightly obliquely cut at the mouth, loosely to rather densely covered with white hairs, sometimes with few black hairs mixed in; teeth subulate, 1–1.5(–2) mm, hairy on inner side. Petals pale purplish to purple. Standard 9−11 mm; blade 4–5 mm wide, elliptic, slightly to deeply emarginate, at the base gradually narrowed. Wings 8–8.5 mm; blades narrowly oblong, distinctly emarginate, 5 × 1.2–1.5 mm; auricle c. 0.5 mm, claw 3−3.5 mm. Keel 6–7 mm; blades obliquely elliptic, with widely curved lower edge and ± slightly convex upper edge, subacute, 3 × 1.8−2 mm; auricle minute, claw 3–3.5 mm. Stamen-tube truncate at the mouth. Ovary sessile, narrowly oblong, sparsely white hairy; style glabrous. Legumes sessile, obliquely erect, narrowly oblong, slightly curved, slightly to distinctly torulose, 11–16 mm long, 3–3.5 mm high and 1.5–2 mm wide, keeled ventrally, slightly grooved dorsally, shortly acuminate, bilocular; valves thin but tough, rather densely covered with appressed, symmetrically to asymmetrically bifurcate to partly subbasifixed white hairs 0.3–0.5 mm, partly glabrescent with age.
