Robust perennial, usually with several erect sparingly branched stems, usually 1-2(-3) m tall; stems hollow, ribbed, appressed pubescent. Leaves 3-foliolate; leaflets linear-lanceolate, oblanceolate-elliptic, elliptic or obovate, mostly 2-14(-20) x 1-6 cm, thinly to densely appressed pubescent beneath; petiole shallowly and broadly grooved, (0.7-)2-6 cm long. Stipules linear-lanceolate, (3-)6-9 mm long, deflexed. Racemes shortly and stoutly pedunculate, up to 20-50 cm long, sub-densely many-flowered; bracts linear-lanceolate, caudate, (6-)8-11 mm long; bracteoles inserted on the upper half of the pedicel, filiform, 2-5 mm long. Calyx 9-12 mm long, subglabrous to appressed pubescent; lobes triangular, ± as long as the tube or a little longer. Standard subcircular, yellow, veined and suffused with maroon or purple at the base inside, veined and sometimes diffused outside, glabrous except sometimes at the apex outside; wings oblong-obovate, longer than the keel, dark marked at the base; keel rounded about the middle, with a short incurved twisted beak, 1.2-1.5 cm long. Legume shortly stipitate, broadly oblong-clavate, 4.5-6.5 x 1.5-2 cm, usually glabrous (occasionally hairy in Ethiopia), ±26-34-seeded. Seeds oblique-cordiform, with the narrow end strongly incurved, ±4 mm long, smooth or papillose around the hilum, iron-grey.
A tall herb or shrub. It grows 1.8 m high. It is stiffly erect with few branches. It has some fine hairs. The stem has some ribs. The leaf stalk is 4 cm long. The leaflets are broadly oval. They are 9 cm long by 5 cm wide. They have a blunt tip with a small point. There are many large flowers. They are in 45 cm long groups at the ends of branches. They are yellow. The fruit is a pod 5 cm long by 1.5 cm wide. It becomes more broad towards the end.
