    Leaves
    Leaves 3-foliolate; leaflets mostly 1.5–8(11) × 0.3–2.5(3) cm, very variable, linear-lanceolate to elliptic or obovate, often varying up the stem, narrowest towards the top, appressed pubescent beneath, sometimes also above; petiole shorter than the leaflets; stipules (0.5)1–3 mm long, linear or subulate, often recurved.
    Inflorescences
    Racemes 5–40(60) cm long, usually with a long peduncle and numerous flowers crowded above (but sometimes peduncle shorter than the rhachis); bracts 1–3(5) mm long, subulate or linear-caudate, expanded at the base; bracteoles inserted at the base of the calyx or just below, 0.5–2 mm long, linear.
    Calyx
    Calyx 3–4(5) mm long, becoming basally truncate and deflexed against the pedicel, variously appressed or less commonly spreading pubescent; lobes narrowly attenuate-triangular, a little longer than the tube.
    Corolla
    Standard obovate-circular, yellow, veined reddish-brown or purplish; wings ± as long as the keel; keel (5)6–9.5(10.5) mm long, strongly rounded about the middle, with an incurved attenuate sharp beak, often lined and blotched purplish.
    Fruits
    Pod practically sessile, 12–24 × 3.5–5 mm, subcylindrical, usually rather densely appressed or spreading pubescent, 20–30-seeded.
