Very large tree, up to 60 m high and 1 m or more in diam.; buttresses 1-3 m high, often very broad. Branchlets slender, pilose to glabrous. Leaves (1-)2-5-jugate, petioles, rhachis, petiolules and midrib pilose to glabrous. Leaflets ovate to oblong, (2-)4-15½ by (1-)2-5½(-6½) cm, charta-ceous; base obliquely rounded, decurrent; margin entire; apex shortly blunt-acuminate; nerves 7-12 pairs (angle 60-80° near base to 30-50° near apex), usually slightly curved, not arching except the apical ones. Inflorescences repeatedly branched from the base, densely glandular-tomentose and sometimes also pilose, 6 ones 10-30 cm long, branches 6-10 cm, slender, female ones 4-22 cm, branches 1-8.5 cm, less slender. Flowers male 2 mm long, ♀ 3 mm. Sepals and petals densely tomentose on either side. Stamens glabrous, in ♂ flowers often twisted. Pistil glabrous. Infructescences with a few fruits; calyx caducous. Fruits 5½-7½ cm long, wings 2-2½ cm broad. Seeds with broad, membranous wings, rounded at the base and acuminate at the apex.

An emergent tree, frequent in old, rarely in secondary, forests; mostly on dry ground, rarely in permanently inundated places, at elevations up to 150 metres, occasionally ascending to 400 metres.
