Tree to 20 m high, 50 cm in diameter. Bark smooth, yellowish, greyish
or pale ochre, or white with brown horizontal ridges, sometimes scaly; sapwood pale yellow to whitish,
heartwood dark yellowish. Branchlets sometimes hollow and inhabited by ants (very often by red
fierce tailor-ants). Branchlets terete, glabrous. Leaves: rachis 4-15 cm, glabrous,
glands oblong or rhomboid, hardly raised or cushion-shaped, without raised margins, 3-5 mm;
pinnae (1 or) 2 pairs, c. 5-15 cm, glabrous, glands obtriangular or rhomboid, flat, sessile, without
raised margins; petiolules c. 6-8 mm, glabrous; leaflets 2-4 pairs per pinna, opposite, rigidly chartaceous,
drying dark green above, bright green beneath, ovate, ovate-elliptic, elliptic, or obovate-elliptic,
c. equal-sided, 3.5-20(-37) by 3-9(-18.5) cm, base symmetrically rounded or broadly
cuneate, apex shortly and obtusely acuminate, both surfaces glabrous; principal lateral veins 6-8 per
leaflet-half, c. parallel, strongly oblique, slightly arching, some of the secondary lateral veins forming
trabeculate anastomoses; reticulation prominulous above, prominent beneath. Inflorescences
terminal and axillary at the distal leaves, yellowish sericeous in the distal parts, glabrescent, consisting
of pedunculate glomerules aggregated into panicles, c. 50 by 30 cm; glomerules consisting of 2-6
(sub)sessile flowers; floral bracts orbicular, obtuse 0.5-1 mm, sericeous. Flowers pentamerous, bisexual.
Calyx yellow or yellowish-green, broadly campanulate, 1.5-2(-4) mm, scarcely sericeous;
teeth triangular acute, 0.5-1 mm. Corolla yellow or yellowish-green, campanulate, 4.5-5(-9) mm,
sericeous; lobes elliptic-lanceolate, acute, reflexed, 2-2.5(-4) mm. Siamens white, c. 6 mm, tube
equalling the corolla-tube. Ovary solitary, glabrous. Pod yellowish or red-brown outside, reddish-orange
within, curved into a circle 4.5-8 cm in diameter, valves 2-3.5 cm wide, coriaceous, not sinuate,
often spirally twisted after dehiscence, glabrous, inconspicuously veined, dehiscing along both
sutures. Seeds black with a bluish bloom, ellipsoid, c. 17-21 by 10-11(-15) mm.
Primary and secondary rain forest, common at forest margins and along rivers and creeks; soil sandy or
clayey, brown or black, but also on or near limestone; altitude 0-600 m.
Roots used as fish poison. The wood is locally used for construction
purposes. Pounded leaves used against lice.
