Tree 10-20 m. Twigs 3-5(-10) mm diameter, late glabrescent, hairs dense, 0.2-0.3 mm long; bark grey (-brown), finely striate, not flaking; lenticels many, not conspicuous. Leaves chartaceous to coriaceous, elliptic-oblong to (obovate-)oblong, 13-21 by 4-9.5 cm, base attenuate, apex acute-acuminate or bluntish; upper surface drying dull olivaceous to brown, lower surface pale brown, glabrous or with persistent hairs 0.2-0.3 mm long on and near the midrib and lateral nerves; dots absent; midrib ± raised above, early glabrescent; nerves 11—14(—18) pairs, above flat or ± sunken, lines of interarching regular, not distinct; venation hardly visible on both surfaces; petiole 8-13 by 2.5-3.5 mm; leaf bud 10-15 by 2.5-3 mm, with dense hairs 0.2-0.3 mm long. Inflorescences behind the leaves, with hairs 0.2-0.3 mm; in male: about 3 times branched, many-flowered, 3-10 by 2-6 cm, peduncle 0.2-0.7 cm long; in female: few-flowered, 1-2 cm long; bracts not seen, caducous; flowers solitary or in loose clusters of up to 5, glabrous, perianth 3-lobed, pedicel ± articulated. Male flowers: pedicel 1-3 mm long, slender; buds ellipsoid(-obovoid), 3-4(-5) by 2-2.5 mm, apex rounded, base ± attenuate to rounded, cleft 1/5-1/4, lobes 0.2-0.3 mm thick; androecium long-ellipsoid, apex truncate to rounded, subcylindrical to ± triangular, 2-3 by 1.1-3 mm (Plate 2: 47); thecae 20-24, almost entirely sessile, mutually appressed, free apices to 0.1 mm, column at apex narrowly hollowed or cleft to 0.3 mm, androphore narrow, to 0.1 mm long. Female flowers (Sinclair 1958): pedicel stout, 3 mm long; buds long-ellipsoid, 5-6 mm long; ovary 2.5-3 mm long, glabrous, stigma sessile, bilobed. Fruits up to 3 per infructescence, ovoid-ellipsoid, apex obtuse to acutish, base broadly rounded, 2.2-2.4(-3) by 1.6-2 (-2.5) cm, glabrous, drying bright brown, without lenticels or warts; pericarp 3 mm thick; fruiting pedicel 3-5 mm long; perianth persistent (always?).
