A much-branched round-topped tree up to 27 m. high.. Young stems with a conspicuous rusty-brown tomentum.. Leaves: petiole 8–32(–45) mm. long; lamina very variable in shape, broadly elliptic or elliptic to broadly ovate or lanceolate, 3–14 cm. long, 2–6(–8) cm. wide, cuneate, rounded, truncate or shallowly cordate and usually somewhat asymmetrical at the base, acute to acuminate or obtuse; upper and lower surfaces often pubescent when very young but quickly glabrescent; stipules broadly ovate to oblong, up to 15 × 4 mm., golden-brown, striate (see Faulkner 730).. Flowers in axillary racemes often aggregated towards the ends of branches into leafy pseudopanicles; infiorescence-axes tomentose with rusty-brown hairs; bracts oblong-concave, 2–4 mm. long, caducous; pedicels 6–18 mm., with rusty-brown indumentum; bracteoles ovate or lanceolate to elliptic or oblong, 2–4.5 × 1–2.2 mm., with rusty-brown tomentum, usually inserted immediately below the calyx but occasionally up to 4 mm. distant from it.. Calyx 8–13 mm. long, glabrous except for a small tuft of hairs at the apex (in marked contrast to the bracteoles), at anthesis splitting down 2 sides into 2 separate halves.. Petals white, the standard with a yellow or orange blotch near the base; standard 14–21 mm. long; wings and keel-petals 12–17 mm. long.. Stamen-filaments glabrous; anthers 1–1.5 mm. long.. Ovary glabrous, black.. Pods (7–)9–14 × (1.8–)2.5–5 cm., somewhat woody, pale straw-coloured.. Seeds lenticular, up to 18 × 14 × 5 mm., reddish-black.. Fig. 10, p. 54.
Dry evergreen and riverine forests; coastal forest and bushland; thickets and savannah, usually at elevations up to 400 metres, but occasionally to 900 metres.
