Inflorescences axillary, 1-2-flowered; bracts 3-4 mm long, linear, with ciliate margins, caducous; peduncle very short; pedicels 1.2-2 cm long at anthesis. Hypanthium with reddish glands.

Petals orange to yellow, 14-16 x 7-9 mm, including a claw c. 2 mm long, obovate, slightly unequal. Stamens 10; three fertile with anthers 4-5 mm long and filaments 3-4 mm long, four fertile with anthers c. 2 mm long and filaments c. 2 mm long; two trumpet-shaped staminodes 3 mm long and one linear staminode c. 2 mm long.

Pod 13-20 x 0.5-0.7 cm, linear, falcately curved or straight, elliptic in section, acuminate at apex, tardily dehiscent along both sutures. Seeds olive-brown, c. 5 x 2-3 mm, rhomboid, with a linear areole on each broad face.
Herb or undershrub up to 1 m tall, rarely higher (2.5 m), usually foetid smelling, glabrous or thinly pubescent. Stipules setaceous, 10-15 mm, caducous. Leaves with 3 pairs of leaflets; petiole 1-4 cm; rachis 2-3 cm, with a subulate, 2 mm long gland between the lowest pair of leaflets. Leaflets obovate, shortly petiolulate; membranous, 1-6 by 0.5-4 cm, increasing in size distally, apex rounded and mucronate, base cuneate. Racemes axillary, 1-or 2-(or 3-)flowered on a very short peduncle; bracts linear, acute; pedicels 1.5-3.5 cmlong, elongating to 2-4.5 cm in fruit. Sepals subequal, ovate, 5 by 2-4 mm. Petals yellow-orange, unequal, short-clawed, 1-2 cm long. Stamens 7, nearly equal, filaments 1.5-2 mm, anthers 3 longer, 4 smaller 1.5-2.5 mm, opening by apical pores, the three larger anthers narrowed shortly below the apex like a bottleneck; staminodes 0-3. Pods linear, terete, falcate to straight, 13-23 by 0.4-0.7 cm. Seeds 20-30, ovoid-rhomboid, 5-6 by 2-4 mm with very narrow areoles 3-4.5 by 0.3-0.5 mm.
Herbaceous perennial or subshrub, erect or spreading, to 2 m high but often lower, sparsely pubescent on vegetative parts, calyx and ovary, soon glabrescent. Leaves 4–6 cm long including a channelled petiole 15–20 mm long; stipules lanceolate, acicular, somewhat persistent; leaflets in 2 or 3 pairs spaced 12–15 mm apart, obovate, 40–50 mm long, 20–30 mm wide, markedly increasing distally, obtuse and mucronate; glands 1 or 2, between the lowest leaflet pairs, erect. Inflorescence subumbellate, of 1 or 2 flowers, axillary; peduncle 2–4 mm long; pedicels 15–20 mm long; bracts caducous. Petals 8–10 mm long. Fertile stamens 7, with 3 adaxial staminodes; fertile filaments unequal, 1–4 mm long; fertile anthers unequal, 3–5 mm long, shortly beaked. Pod cylindric, 12–18 cm long, c. 3 mm diam., curved, entire. Seeds dull or lustrous, with a narrow, oblique areole.
An annual or perennial herb. Often it has a bad smell. It can be a shrub 0.6-2.5 m tall. It has slightly hairy stems. The leaf stalk does not have a gland but the axis of the leaf does. The leaf has leaflets in 3 pairs. They are oval and 1-6 cm long by 0.5-3.9 cm wide. The top of the leaf is rounded but with a sharp tip. It is wedge shaped at the base. The flower stalks have one or 2 flowers. The stalk for the flower cluster is very short, but the stalk for the individual flowers is 1-3.5 cm long. The flower petals are orange-yellow and 1-2 cm long. The fruits are thin slightly curved and tapering pods. They are 13-23 cm long and 4-7 mm wide. The seeds are brown. They are 4.5-6.5 cm long by 2-4 mm wide.
