Tree to 30 m, but often much less; bole to 60 cm diam., sometimes fluted at base or with buttresses to 1 m tall, 30 cm out. Bark pale brownish grey, smooth and lenticellate to scaling, brittle; inner bark pale yellowish brown, sometimes mottled; sapwood pale yellow; heartwood red-brown with sour smell. Twigs angled and cicatrose, often dull purple-tinged when young, leafy ones 5–7 mm diam. Apical buds stiletto-like. Leaves to 67 cm long, ± imparipinnate with a scar next to the ‘terminal’ leaflet, 4-or 5(–6)-jugate; petiole c. 15–22 cm, 3–5 mm diam., flattened adaxially, glabrescent; rachis 2–3 mm diam., glabrescent. Leaflets 18–23 by 6–12 cm, oblong-ovate, sometimes narrowly so, ± glabrous, sometimes sparsely hairy on venation abaxially, leathery, subsessile, base ± asymmetric, acute to subcuneate, apices acute to (long-)acuminate, costae 7–13 on each side, squarrose at origin, looping but scarcely joining at margin, sometimes yellowish in sicco; petiolules 0–5 mm. Inflorescences 8–25 cm long, spicate to scarcely branched, squarrose, axillary to ramiflorous, axes sparsely hairy, subsessile cymules 1–7-flowered; bracts c. 1 mm long, subtriangular. Flowers fragrant (honeysuckle, Mabberley). Bracteoles minute. Calyx c. 4 mm long, apically cupular, basally a pseudopedicel, ± puberulent without, olive-green, margin 4-(or 5-)toothed, valvate. Petals 4 (5), c. 5–7 by 2 mm, elliptic-oblong, valvate to apically imbricate, puberulent without, yellowish, sometimes pinkish apically. Staminal tube glabrous, off white, weakly hairy without, margin 8– (or 10–) toothed; anthers (6–)8(–10), c. 1.5 mm long, elliptic-ovate, yellow, ± included. Disk c. 1–1.5 mm tall, not exceeding ovary, glabrous, margin irregularly c. 8–12-toothed. Ovary (2– or) 3-locular, hairy, each locule with 2 collateral ovules; style cylindical, furrowed, hairy, pale green; stylehead subcapitate, with basal annulus, white to pale orange. Capsule c. 4 cm long, 5 cm diam., globose to fig-shaped, often veiny or wrinkled, orange-red (black in sicco), dehiscent; the pericarp with white latex. Seeds 1–6, c. 25–35 mm long, 15–20 mm across, elliptic to suboblong, shiny brown-orange, (?) sarcotestal.

A mid-canopy tree in undisturbed mixed dipterocarp and sub-montane forests; common on hillsides and ridges, but also along rivers and on alluvial sites; growing on clay to ultrabasic soils; at elevations up to 2,000 metres.

Can be grown by seedlings.
