Podlech & Zarre (2013), vol. I, p. 814Plants up to 20 cm tall, covered with appressed to subappressed hairs 0.3–0.5 mm. Stems 4–15 cm, prostrate to ascending, glabrous or sparsely, sometimes rather densely white hairy. Stipules 6–8 mm, high up vaginate-connate behind the stem, glabrous or sparsely ciliate at the margins. Leaves 3–4 cm; petiole 1–1.5 cm, hairy like the stem. Leaflets in 5–7 pairs, narrowly elliptic, 5–16 mm long, on upper side glabrous, on underside sparsely hairy, especially at midvein and margins. Peduncles 3–4 cm, in basal parts sparsely, toward the raceme rather densely white hairy. Racemes short, slightly elongated at fruiting time, densely 5–10-flowered. Bracts whitish-membranous, narrowly triangular, c. 5 mm, white and black or predominantly white hairy. Pedicels 0.5–1 mm, hairy. Calyx 6–7 mm, campanulate-tubular, black or white and black hairy; teeth subulate to narrowly triangular, 2–3 mm, black hairy on inner side. Petals whitish-pink, yellowish or bluish when dry, keel with a darker tip. Standard 12–14(–16) mm; blade 8–10 mm wide, slightly emarginate, gradually narrowed at the base. Wings 10–12 mm; blades 6–7 × 2.5−3 mm, distinctly widened toward the tip, unequally bilobed; auricle c. 1.5 mm. Keel 10–11 mm; blades obliquely obovate, c. 5 × 3 mm, obtuse; auricle c. 1 mm. Ovary with a stipe c. 3 mm, glabrous. Legumes with a stipe 8–10 mm, narrowly ellipsoid, nodding, 20–30 mm long, 7–12 mm high, unilocular; valves sometimes reddish, glabrous. Chromosome- number: 2n = 48 (JURTSEV, B.A. & ZHUKOVA, P.G., Bot. Dzhurn. 53: 1534. 1968; TAKHTAJAN 1990).
