Flowers 1–2 on filiform leaf-opposed peduncles scattered along the branches; peduncle usually c. 1 cm long, rarely up to 3 cm; bracts 1–3 mm long, linear or linear-lanceolate; bracteoles inserted at or near the top of the pedicel, linear.
Standard elliptic-obovate to subcircular, white becoming flushed red outside or rarely yellow, apically pubescent outside; wings exceeding the keel; keel 3–6 mm long, abruptly rounded with a practically straight tapered beak.
Leaves estipulate, sessile, 3-foliolate; leaflets 6–14 × 1.5–3(5) mm, oblanceolate to narrowly elliptic-oblong, ± pointed, sparsely to quite densely pilose on both surfaces.
Calyx 3–7 mm long, shortly appressed to rather coarsely pubescent; lobes narrowly attenuate-triangular, usually twice as long as the tube.
Pod subsessile, 1–1.6 cm long, cylindrical, spreading pubescent outside and also inside (at least along lower suture), 6–8-seeded.
Seeds 2–2.5 mm long, oblique-cordiform, smooth.
