Tree 6-25 m. Twigs 2.5-5 mm diameter, grey-brown, early glabrescent, hairs greyish brown, 0. l(-0.2) mm; bark coarsely longitudinally striate, not flaking; lenticels small, rather inconspicuous. Leaves membranous or thinly chartaceous, (elliptic-)oblong, 15-27 by 5.5-9.5 cm, base attenuate, apex acute-acuminate; upper surface glabrous, drying olivaceous-brown, lower surface brown, not conspicuously contrasting in colour with upper surface, early glabrescent; dots absent; midrib raised above; nerves 11-19 pairs, raised above; venation lax, indistinct on both surfaces; petiole 10-20 by 2-2.5 mm, leaf bud 10-15 by 2-3 mm, with grey brown hairs 0.1 (-0.2) mm. Inflorescences with rather dense stellate hairs 0.1 mm long; in male: 2 or 3 times branched, not very many-flowered, 8 by 4-5 cm, peduncle 1-1.5 cm; flowers in clusters of 2-5; in female: 2-5 cm long, twice branched, fewer-flowered; bracts ovate-oblong, 4 by 2 mm, with dense hairs 0.2 mm long, caducous; flowers with perianth 3-(or 4-)lobed, glabrous, pedicel glabrous or sparsely pubescent (hairs 0.1 mm), articulated. Male flowers: pedicel 2-3 mm long; buds broadly ellipsoid or obovoid, 2-3 by 1.8-2.5 mm, apex rounded, base short-attenuate, slightly tapering, cleft 1/3 to 1/2, not or slightly collapsing on drying, lobes thick, 0.3 mm, towards the base to 0.8(-l) mm thick; androecium (including the broad, shortly tapering, 0.2-0.5 mm long androphore) ellipsoid to ellipsoid-oblong, (1.4-) 1.7-2 by 0.8-1 mm, in cross section subtriangular to subelliptic (Plate 3: 87); thecae 14-18, slightly curved, 1.2-1.8 mm long, free apices (0.2-)0.3-0.5 mm. Female flowers: pedicel 2-3 mm long; buds broadly obovoid, 2.5 by 2.5 mm, cleft c. 1/3; ovary ellipsoid, 1.8-2 by 1.3-1.5 mm, glabrous, stigma 2-lipped, 0.3 mm high. Fruits 1-5 per infructescence, ellipsoid, 4.3-6.5 by 3-4.5 cm, glabrous, drying rusty-brown, finely granulate, not or inconspicuously warted or lenticellate; pericarp 4-11 mm thick; fruiting pedicel 2-7 mm long; perianth not persistent.
