    Leaves
    Leaves 18–22 cm long; petiole 2–3 cm long, rachis 9–11 cm long, hispid-glandular; petiolules 5–6 mm long, appressed-pubescent; leaflets 3–4 on each side of the rachis, alternate, 2–9 × 2.5–4 cm, ovate or elliptic to obovate, usually abruptly and shortly acuminate, often slightly emarginate at the apex, thin and stiff, deep green and glabrous on upper surface (when mature), paler and sparsely strigulose beneath; lateral nerves in 7–12 pairs, reticulation rather close, conspicuous on both surfaces; stipules caducous.

    Inflorescences
    Inflorescence (in East African material) of panicles in axils of upper leaves, 10–19 cm long, with a few lax rather spreading primary branches, many-flowered; bracts 1–3 mm long, lanceolate to ovate, caducous; bracteoles 3–6 mm long; pedicel small and narrow.

    Fruits
    Pod 1-seeded, stipitate, circular, 14.5 cm in diameter (Mozambique material); wing papyraceous, undulate and flaccid, sparsely pubescent, sometimes with a few scattered bristly hairs, asymmetric at the base, style-insertion bent down overlapping the stipe and producing a deep narrow sinus, thickened-umbonate over the seed, quite glabrous (when ripe).

    Distribution
    Also in SE Tanzania.
    Ecology
    Coastal and riverine forest; 0–600 m.
    Conservation
    Conservation notes: Within the Flora Zambesiaca area known from only a single collection, and from only a few collections overall. Probably best assessed as Vulnerable B1.

    Corolla
    Corolla 11–13 mm long, cream or yellow, fragrant; standard broadly ovate; wings broadly expanded, enveloping the keel and nearly as long as the standard.
