A semi-woody shrub. It grows 2-4 m high. The leaves are compound. They have 3-5 leaflets each 5-11 cm long. The flowers are yellow. They are in groups 20-40 cm long at the ends of branches. The fruit are pods 4-5 cm long and contain 30-40 seeds.
Leaves 3–5-foliolate; leaflets 4–12 × 1.5–5.5 cm, elliptic, sometimes narrowly so, often acuminate, hairy at least beneath, discolorous, dark green above; petiole shorter than the leaflets; stipules 1–5 mm long, subulate to linear-caudate.
Standard elliptic, bright yellow, usually veined reddish-brown; wings markedly shorter than the keel; keel 1.2–1.7 cm long, rather strongly rounded about the middle, with a narrow beak incurved towards the tip.
Racemes mostly 10–30(40) cm long, rather shortly pedunculate, subdensely many flowered; bracts 2–8(10) mm long, subulate or linear-caudate; bracteoles at the base of the calyx, 2–8(10) mm long, linear-caudate.
Calyx 6–7 mm long, becoming basally truncate and deflexed against the pedicel, appressed puberulous to spreading tomentose; lobes narrowly triangular-acuminate, as long as the tube or longer.
Pod shortly stipitate, (3.5)3.8–5(6) cm long, narrowly cylindrical, sometimes shortly curved upwards at the tip, sparsely puberulous to densely spreading pubescent, 30–40-seeded.
Shrubby much branched perennial 1–4.5 m tall; branches variously appressed puberulous to spreading yellowish tomentose.
Seeds 3–4 mm long, oblique-cordiform, smooth, brown.
