Description:
Softly woody herb, slender shrub or small tree, (1)2–6 m tall; glabrous throughout except for the calyx margin and inner surface of the calyx teeth. Stems greyish-green often tinged purplish-black, aculeate or completely without prickles. Leaves up to 45 cm long, the rachis aculeate or not; petioles up to 3.5 cm long; leaflets in 9–64 pairs, 0.7–4.4 cm × 2.5–13 mm (the basal pair sometimes much smaller than the others), oblong, obtuse to slightly emarginate at the apex, apiculate, slightly asymmetrical at the base, entire; stipules 0.9–2.9 cm × 2–5 mm, lanceolate to ovate-lanceolate, acuminate, slightly falcate, erect, caducous or occasionally rather persistent. Raceme 6.3–27.2 cm long (especially long in E Zimbabwe), 5–21-flowered; peduncle 1.6–10 cm long, aculeate (sometimes so densely so that the prickles fuse to form dentate ridges) or completely without prickles. Calyx 5–12 × 6–10 mm, the teeth 1–2 mm long, broadly acuminate. Standard deep yellow, flecked or spotted with violet or purple on the outer face, 1.6–2.6 × 1.7–2.5 cm, the blade first widening gradually from the claw and then very abruptly so that it is subcordate just below the middle, apically emarginate, appendages semicircular or broadly triangular and without free tips; wings yellow, 1.3–2.1 cm × 4–9 mm, with upper basal acuminate tooth slightly hooked or ± horizontal and with lamellate sculpturing in upper basal and central sections on outer face; keel greenish-yellow, slightly speckled with purple, 1.3–1.6 cm × 7.5–11 mm, the basal tooth usually large, horizontal, ± parallel to the petal-claw. Pod 14.5–31 cm × 3.5–8 mm, curved, long acuminate, thicker at the centre than at the sutures which are sometimes slightly constricted between the seeds particularly along the upper margin, 12–30-seeded. Seeds dark olive-brown to almost black, not mottled, 6–8 × 2.5–3.5 mm, 2–3 mm thick, subcylindrical to cylindrical; hilum in ± central circular pit surrounded by a white rim aril.
