Podlech & Zarre (2013), vol. III, p. 2254Plants 3–16 cm tall, acaulescent, with appressed, medifixed hairs 0.3–0.5(−1), at the fruit with partly spreading and mostly asymmetric hairs. Rootstock up to 8 mm in diameter, very shortly branched. Stipules narrowly triangular, 3–5 mm, adnate to the petiole for 1–1.5 mm, densely hairy. Leaves 1.5–12 cm; petiole 0.5–4 cm, like the rachis grooved adaxially, rather densely to densely white hairy. Leaflets in (2–)4–8(–12) pairs, elliptic or ovate to widely obovate or nearly orbicular, 3–14 × 2.5–9 mm, widely rounded to slightly subacute, on upper side loosely or more rarely rather densely hairy, mostly spotted with minute dark reddish dots, on lower side densely hairy. Peduncles 1.5–9 cm, densely hairy, somewhat glabrescent with age. Racemes short, loosely 1–12-flowered, in fruit elongated. Bracts narrowly triangular, 2–4 mm, white hairy. Pedicels 1–2 mm, white hairy. Bracteoles linear, 0.5–2 mm, at the base of calyx, rarely absent. Calyx often dark reddish, 10–14(−17) mm, tubular, obliquely cut at the mouth, loosely to rather densely covered with white and black hairs, sometimes predominantly white hairy with few black hairs only; teeth unequal, subulate, 2–6 mm, densely white hairy on inner side. Petals yellowish ?, drying to violet. Standard 19–23 mm; blade slightly curved upward, 8–11 mm wide, widely oblong-obovate to widely elliptic, sometimes shortly narrowed toward the widely to narrowly rounded, scarcely emarginate tip, angularly passing at the base into the cuneate claw. Wings 18–21 mm; blades narrowly oblong, slightly to conspicously dilated upward, obliquely laterally emarginate, 8–9 × 3–4.5 mm; auricle 1–1.5 mm, claw 9–14 mm. Keel 16–19 mm; blades obliquely narrowly elliptic-curved with widely curved lower edge and distinctly concave upper edge, subacute, 7–8 × 2.5–3.2 mm; auricle very short, claw 9–13 mm. Stamen-tube ± truncate at the mouth. Ovary with a stipe 1–2 mm, linear, white villous; style glabrous. Legumes ± sessile, linear, slightly curved, narrowed at the base, 22–45(−52) mm long, (3.5−)4–5 mm high and c. 3 mm wide, keeled ventrally, slightly to distinctly grooved dorsally, tapering into a straight beak up to 5 mm, bilocular; valves brownish, sometimes indistinctly to distinctly reddish-mottled, partly across wrinkled-rugose, loosely to densely covered with appressed to adscending or even spreading, extremely asymmetrically bifurcate to basifixed, tangled hairs 0.7–1 mm.
