Tree to 32 m high, stem diameter 68 cm. Branchlets terete, glabrous (or tomentellous). Stipules filiform, subulate, 1.5-2 mm, early caducous. Leaves: rachis 5-15 cm, glabrous to patently puberulous with one gland 1.5-2.6 cm above the base, additional glands above the junctions of the 2 or 3 distal pairs of pinna, circular, raised, flat to slightly concave, 0.5-0.8 mm in diameter; pinnae (2-)3-7 pairs, subopposite to opposite, puberulous or tomentose, 4-12 cm, glands at the junctions of the 6 or 7 distal pairs of leaflets, elliptic, slightly raised, concave, c. 0.3 mm; leaflets (5-)10-25 pairs per pinna, opposite, sessile, chartaceous, asymmetrically (elliptic-) oblong, lanceolate or subfalcate, 0.7-2(-2.7) by 0.25-0.6(-1.4) cm, base obliquely half rounded/ half cuneate, apex rounded to acute, mucronate, both surfaces sparsely appressed puberulous or glabrous, often with a few scattered hairs along the margins; main vein excentric, not parallel to the front margin, distant by about ⅓ of the width of the leaflet. Inflorescences consisting of pedunculate glomerules aggregated into terminal and axillary puberulous to shortly tomentose panicles; peduncles 2-5, fascicled, 1-3 cm, glomerules with c. 10-15 flowers. Flowers bisexual, sessile, uniform, pentamerous, fragrant. Calyx pale green, narrowly campanulate, 1-1.5 mm, puberulous to tomentose, teeth triangular-deltoid, c. 0.25 mm. Corolla pale green, tubular to narrowly funnel-shaped, 4-5 mm, puberulous to villous, lobes narrowly ovate or elliptic, c. 1 mm. Stamens white, to c. 6 mm, tube longer than the corolla-tube, often equalling the corolla. Ovary glabrous, 1-1.5 mm, sessile. Pod dark brown, flat, straight or slightly curved, oblong, 8.5-15 by 1.6-2(-2.8) cm, gradually narrowing in the stalk, dehiscing first along the ventral suture; valves thinly chartaceous, glabrous, with distinct marks over the seeds, veins inconspicuous. Seeds obovate or suborbicular, flattened, c. 7 by 5 by 1.5 mm; areole ovate-elliptic, 4 by 2 mm, the pleurogram not parallel to the margin, open towards the hilum.

A small tree. It grows 7-8 m tall. It has drooping branches. The young branches are slightly hairy. The bark is hard and grey. The leaves are twice divided and have two rows of leaflets and the leaflets are narrow. There are 7-8 pairs of first leaflets then 10-23 pairs of small leaflets. These leaflets are oblong and 0.7-1.8 cm long by 2-4.2 mm wide. They are asymmetrical at the base. The flower cluster is towards the ends of branches. The flowers are small, greenish yellow and occur in clusters in compound flowers. They have a thin pod. The pod is 8-12 cm long by 1.6-2.2 cm wide. It is dark brown. They contain 7-10 seeds.
Deciduous forests in dry localities, less commonly in savannah and evergreen forests, preferring open locations, such as forest margins, road and stream sides, and forest clearings, occasionally in shaded habitats, at elevations up to 800 metres.

It is a tropical plant. It is common and distributed from northern Luzon to southern Mindanao. It grows from sea level to 20 m altitude. It tends to grow in drier savannah locations.
Can be grown by seedlings. Seeds needs soaking.
