Leaves mostly crowded on very short axillary shoots, appearing fasciculate, 3-foliolate; leaflets oblanceolate, rarely obovate, up to 12–20 mm. long, 4–9 mm. wide, thinly pilose on both surfaces; petiole ± 5–17 mm. long.. Stipules attenuate-subulate, up to 3 mm. long.. Inflorescences of 2 sorts, both pedunculate terminal or leaf-opposed racemes, up to 4–13 cm. long, with few to numerous somewhat laxly arranged flowers, and also with 1–4 flowers on axes up to 2 cm. long apparently axillary from the leaf-clusters; bracts linear-caudate, ± as long as the pedicel or longer, 3–7 mm. long; bracteoles inserted on the upper part of the pedicel, filiform, up to 4 mm. long.. Calyx 5·5–8 mm. long, with the tube slightly protracted on the lower side, spreading pilose; upper lobes very narrowly attenuate-triangular, 2–3 times as long as the tube.. Standard broadly elliptic or suborbicular, yellow, veined reddish-brown and densely rather spreading pubescent outside; wings oblong-obovate, nearly as long as the keel; keel bent at right-angles in the lower half, with a narrow twisted beak, (8–) 10–12 mm. long, lanate along the upper margin.. Pod subsessile, ellipsoid or obovoid-ellipsoid, 8–16 mm. long, 6–9 mm. across, pilose outside and sparsely so inside, ± 8–10-seeded, rarely less..
