Leaves 12–28 cm long; petiole 3–5 cm long; rachis 8–20 cm long, tomentellous; petiolules 1–1.5 mm long; leaflets (5)6–10 on each side of the rachis, (1.5)2–6 × 1–2.5 cm, elliptic to narrowly elliptic or oblong-ovate rarely obovate, ± asymmetric at the base, acute to rounded or sometimes obtuse at the apex, recurved at the margin, broadly obtuse to rounded, rarely subcordate at the base, coriaceous, glabrous on upper surface, puberulous beneath; midrib impressed above, prominent beneath; lateral nerves in 4–7 pairs, scarcely visible on upper surface, slightly prominent beneath; stipules 3–7 mm long, linear, falling early.
Inflorescence a very dense to lax racemose panicle 6–36 cm long, borne precociously on leafless stems, occasionally also in the axils of last season’s leaves, fulvous-or rufous-tomentellous; bracts 2–3.5 mm long, linear, falling early; bracteoles minuscule or absent.
Standard 9–10 mm long, suborbicular, somewhat reflexed, broadly emarginate, claw c.3 mm long; wings as long as the standard, auricle ciliolate, claw 4 mm long; keel petals broader than the wings, sparsely puberulous, auricle ciliolate, claw c.5 mm long.
Pod 1-seeded, 5–8.5 × 2–2.5 cm, rounded at the apex, broadly obtuse or cuneate at the base, densely fringed with plumose hairs on the margins, particularly the upper, otherwise pubescent-glabrescent, indehiscent.
Flowers 10–12 mm long, white or cream with the standard at least partly purple, clustered on nodes or on very short pedicels; pedicels 3–7 mm long.
Deciduous tree up to 10 m tall; crown irregular; bark rough, grey to dark brown, longitudinally fissured.
Calyx 4–5.5 mm long, puberulous; upper teeth shallow, rounded, the others obtuse or acute, c.1 mm long.
Ovary 6–8-ovulate, 7–8 mm long, sessile, densely rusty-sericeous; style 2–3 mm long, incurved.
Stamens c.8 mm long, 9 connate in the basal 3–4 mm, the upper one free.
Seed 12–18 × 9–10 × 1.5 mm, reniform; testa reddish-brown, smooth.
