Bark grey, smooth or rugose with red-brown lenticels; inner bark white or dark red to brown; sapwood white; heartwood bright yellow. Fresh leaves dark green with yellowish veins. Branchlets terete to slightly angular, brownish puberulous in the distal parts, glabrescent. Leaves: rachis 1.5-4.5 cm, glabrous to very scarcely puberulous, gland raised, (sub)urceolate, with a narrow orifice, 2-4 mm in diameter; pinnae 1 pair, 2.5-8 cm, scarcely puberulous; petiolules 2-7 mm, glabrous; leaflets 1.5-2 pairs per pinna, proximal pair alternate, distal pair opposite, chartaceous, drying brownish, c. equal-sided, ovate-elliptic, elliptic, or obovate-elliptic, 5.5-22 by 3-12 cm; base symmetrically, asymmetrically cuneate, or rounded, apex obtuse, tip acuminate, upper surface glabrous, lower surface with scattered hairs, glabrescent; principal lateral veins 3-6 per leaflet-half, strongly arching, non-parallel, connected by secondary and tertiary lateral veins which form some trabeculate anastomoses, reticulation prominulous above, prominent beneath. Inflorescences terminal, densely rusty puberulous, consisting of pedunculate glomerules aggregated into panicles, 25 by 10-20 cm; glomerules slightly elongated, consisting of c. 5-12 sessile or subsessile flowers; floral bracts ovate or oblong, acute, c. 1.5 mm, puberulous. Flowers (tri- or) pentamerous, bisexual, fragrant. Calyx green, funnel-shaped, 3.1-4 mm, scarcely or densely puberulous; teeth 3-5, unequal, rounded, 1-1.3 mm. Corolla green or whitish, narrowly funnel-shaped, 6.5-8 mm, tube glabrous, lobes 5, unequal, narrowly ovate or oblong, acute, 2-3 mm, puberulous at the apex and often with papillose margins. Stamens white, c. 12 mm, tube shorter than the corolla-tube. Ovary solitary, glabrous. Pod brown outside, light brown within, straight, turgid, to 16 by 4 cm, only very slightly constricted between the seeds, woody-rigidly coriaceous, glabrous, with inconspicuous veins, dehiscing along both sutures. Seeds brown, bitruncate, subcylindrical, c. 12-35 mm in diameter, 10 mm high. [from Flora Malesiana]

Primary and secondary lowland rain forest, lower montane forest, riverine forest, regrowth; on sandstone, soils recorded as black or brown, terrain flat or sloping; altitude 0-1550 m.

The seeds are edible after boiling or roasting. When crushed the seeds (which are stored in coconut-oil) are used against mosquito and snake bites.

Borneo, but also found in Java and New Guinea where it was probably planted.
