Perennial tree, 3-4 m high; single stemmed; young stems and growing points glabrous or sparsely white-pubescent. Leaves palmately compound with 3-5 pinnae; pinnae narrowly ovate or narrowly obovate, apex acute, base acute, shortly acuminate or rounded, margins entire or toothed in upper half; upper surface glabrous, occasionally sparsely pubescent and glandular; lower surface pubescent and glandular, chartaceous; petioles glabrous or sparsely white-pubescent, petiolules sparsely pubescent. Inflorescence a compound dichasium. Flowering time Nov.-Jan.
Leaves (4)5-foliolate, petiole 3–5 cm long, grooved at the base; median petiolules 0.3–1 mm long; leaflets 6–10 × 2.5–4 cm, elliptic, narrowly ovate to narrowly obovate, rounded and shortly acuminate to acute at the apex, cuneate at the base, entire, drying dark green and somewhat darker above, sparsely pubescent or glabrous and gland-dotted above, pubescent and gland-dotted beneath, nerves raised beneath.
Fruit an obovoid nut, c. 3 × 4 cm, truncate at the apex and sharply tipped with remains of the style, almost fully enclosed in the enlarged calyx, brownish to black at maturity; fruiting calyx bell-shaped, pubescent, not gland-dotted.
Calyx campanulate, 5-lobed, not gland-dotted, tomentellous becoming puberulous or glabrescent outside, accrescent in fruit; tube 2.5–3.5 mm long; lobes 1–2 mm long, tomentellous outside and sparsely puberulous inside, spreading.
Corolla 10–20 mm long, ± puberulous outside, gland-dotted; tube white, c.1.8 mm, funnel-shaped; lobes white or pale mauve, at obtuse angle to tube, middle lower lobe 6–9 mm long.
Tree (2.5)3–7(9) m tall; bark fissured, light to dark grey; young branches and new growth densely puberulous to shortly pale yellow-tomentose.
Inflorescences axillary of ± sturdy compound dichasia, 6–15 cm long, white-tomentose; bracteoles 0.5–0.8 cm long, linear-spathulate.
Ovary obovoid, rounded at the apex, gland-dotted, puberulous except near the base; style c. 7–10 mm long.
Stamens clearly exserted from corolla tube; filaments with glandular hairs.
