Large tree up to 40 m. Bark grey or brown; sapwood whitish. Young branchlets much thickened, rufous-sericeous, becoming glabrous. Leaves spirally arranged, crowded at the thickened ends of the branchlets, rufous-tomentose when young, later sparsely appressed-pubescent or nearly glabrous, shining above, rather sparsely appressed-pubescent and sometimes minutely verruculose beneath, usually opaque, obovate-cuneate, 15-40 by 4½-18 cm, rounded at the apex, narrowly cuneate below the middle and usually subcordate at the base; nerves 24-30 pairs, almost perpendicular to the midrib and rather closely spaced, domatia present but rather inconspicuous and not hairy; petiole thick, at first rufous-sericeous, becoming nearly glabrous, 5-10 mm. Flowers white, in axillary spikes 25-50 cm long; rhachis fulvous-tomentellous. Bracts filiform, 2 mm, soon caducous. ♂ Flowers numerous with appressed-pubescent stalks 3-5 mm long; hermaphrodite flowers few, sessile towards the base of the spike. Lower receptacle (ovary) fulvous-sericeous, 3-6 mm long, narrowed at the apex into a slender stalk above the ovary; upper receptacle nearly glabrous, shallow-cupuliform, 1 by 3 mm. Calyx-lobes glabrous or nearly so, ovate-acuminate, 2 by 1½ mm. Filaments glabrous, 3½-4½ mm; anthers ½-0.6 mm long. Disk barbate. Style glabrous, 4 mm. Fruit sparsely appressed-pilose or nearly glabrous when mature, ovoid or ellpsoid, sometimes slightly laterally compressed, sometimes rather obscurely 5-lobed, often shortly beaked at the apex, 3½-6 by 2.2-3 cm, showing in cross-section very irregular and sinuate sclerenchymatous tissue partly enclosing and partly surrounded by alveolar tissue and a band of corky tissue 2-3 mm thick round the outside.

A large tree up to 40 m tall. Trees often have many buttresses. The twigs are thick and have leaf scars which are prominent. The leaves are crowded at the thickened end of the small branches. Leaves are 22-36 cm long and 9-13 cm wide. They have no real leaf stalk. Flowers are small and white on many flowered stalks 22-30 cm long and near the end of branches. Flowers towards the base of the flower spike are female and the ones towards the end are male. The fruit is 3.5-6 cm long and 2.2-3 cm wide. They are oval and slightly flattened.
A tropical plant. They occur in primary rainforest up to 500 m altitude. This species occurs in Malaysia, Indonesia and the Philippines as well as Papua New Guinea. It is mostly known from the Western Province within Papua New Guinea.
