Leaves shortly petiolate, 3-foliolate; leaflets mostly 2.5–5(6) × 0.8–1.8(2.4) cm, lanceolate to elliptic or obovate, the upper ones often longer and proportionally narrower, glabrous to sparsely pilose above, subappressed pilose beneath; stipules simple or 2–3(5)-fid, up to 5–13 mm long, with both the simple stipules and segments linear-subulate. Flowers numerous in sessile heads; bracts basally fused to the pedicel, spreading from just below the calyx, 3-fid with linear segments up to 10–13 mm long; bracteoles basally fused to the calyx tube, the free part directed forwards, 8–12 mm long, linear. Calyx 7–10(12) mm long, deeply divided, slightly 2-lipped, pilose; lobes subulate, caudate, 4–5 times as long as the tube. Standard elliptic-obovate to subcircular, yellow, finely veined or reddish flushed with age, glabrous except along the midvein outside; wings ± as long as the keel; keel 7–9 mm long, subangular, narrowly beaked.
