Large shrub or tree, 4.5–10(–21) m. tall, laxly branched and with ± spreading crown; bark grey or brown, ultimately rough and flaking in small pieces. Branchlets with a persistent or evanescent yellowish or off-white matted tomentum or practically glabrous. Leaves 10–30 cm. long; stipules oblong, up to 8–15 mm. long, caducous or rather persistent; lateral leaflets 4–8(–9) on either side of rhachis, elliptic-lanceolate to ovate or elliptic-oblong, 3–7.5 cm. long, 1.5–3.5 cm. wide, bluntly pointed, broadly cuneate to rounded or cordate at base, glabrous to tomentose; lateral nerves ± 6–10 on either side of midrib, ultimately prominulous above. Panicles produced in profusion from precocious to full-leaf stage, much branched, spreading, ± 5–13 cm. long, many-flowered; axes often with indumentum grading from tomentose on peduncle to subglabrous on pedicels, but sometimes sparsely hairy or glabrous overall; bracts linear-lanceolate to oblong or oblong-oblanceolate, 1.5–3 mm. long, fugaceous; bracteoles, at top of 2–4(–6) mm. long pedicel, oblong to broadly elliptic, 1–2 mm. long. Calyx 3.5–4.5(–5) mm. long, reddish, glabrous. Corolla 5–7.5 mm. long, white or cream, turning yellowish, fragrant; standard oblong-obovate to obovate or broadly elliptic with a well-developed claw, glabrous; petals all practically the same length. Stamens (8–)9–10, united or very rarely in 2 phalanges. Fruit oblong, narrowed to the pointed or shortly rounded apex, narrowed to the ± 0.8–1 cm. long stipe, 6–11 cm. long, 1–2 cm. wide, papery, reddish-brown, glabrous, obscurely veined, 1–3-seeded.
