Description
Straight-boled, monopodial tree, up to 42 m high; bole to c. 20 m, 150 cm in diameter. Bole sometimes with buttresses to 1 m high, rounded. Bark pale brown to fawn with redbrown lenticels arranged roughly horizontally. Thin, hard outer bark, oriuige inner bark, exudate scanty; sapwood medium hard, white to cream, heartwood chocolate-brown. Branchlets ridged, with reddish brown lenticels and very prominent leaf-scars, sparsely rusty puberulous. Stipules to c. 2.5 mm, erect when young, soon recurved and thorn-like, often caducous. Leaves: rachis 9-38 cm, sulcate, tomentose or glabrous, with gland(s) c. 1-1.5 cm above the base and below the junctions of the distal pairs of pinnae, circular to elliptic, usually raised, cushion- shaped or flat, 1-4 mm long, distal glands smaller; pinnae 5-13 pairs, 5-12 cm, tomentose, with gland(s) just below the junctions of the 1-4 distal pairs of leaflets; circular with slightly raised margins, c. 0.3 mm in diameter; leaflets 9-18 pairs per pinna, opposite, sessile, subcoriaceous, elliptic-oblong, unequal-sided, 0.8-2.3 by 0.3-1 cm, base asymmetrically truncate to half truncate/half cuneate, apex rounded, mucronate; both surfaces glabrous; main vein distant by c. 3/8 of the width of the leaflet from the front margin. Inflorescences composed of pedunculate corymbs aggregated into terminal or axillary panicles, puberulous or sometimes glabrescent; peduncles in umbels of 4 or 5, 2-3.5 cm, bearing corymbs consisting of 20-25 pedicellate flowers. Flowers dimorphic, pentamerous, bisexual. Calyx green, funnel-shaped to narrowly campanulate, sericeous, (3-)4(-5) mm; teeth triangular, acute, c. 0.3 mm. Corolla whitish, funnelshaped, sericeous, 6-8 mm; lobes elliptic-ovate to triangular-ovate, acute, 2-3 mm. Stamens greenish, especially towards the top, c. 20-25 mm, tube to c. 3.5 mm, shorter than the corollatube. Ovary sessile, glabrous, 3.5-4 mm. Pod golden yellow, oblong-linear, straight, strongly flattened, c. 6-30 by 4-5 cm, indehiscent, but valves breaking up irregularly; valves thinly chartaceous-membranous, glabrous, veins inconspicuous, reticulation visible over the seeds only. Seeds yellow, ovate, strongly flattened, c. 1 1 by 7.5 by 1 mm, narrowed at the hilum; areole elliptic(-obovate), pleurogram not parallel to the margin of the seed, open towards the hilum.

Ecology
Primary and secondary lowland rain forest, common in alluvial forest (but rarely collected), often on podsolized sands; altitude 10-240(-500) m. The broad and papery pods are probably well adapted for wind dispersal.

Distribution
Peninsular Malaysia, Sumatra, Borneo, Philippines.

Uses
The dark brown heartwood perhaps makes this an excellent timber tree, but the wood may be too soft to be useful.

Local names
Borneo: Berangan, Sansan lang.
