Tree 10-25 m. Twigs 2.5-5 mm diameter, early or late glabrescent, hairs rusty, 0.1-0.4 mm long; bark coarsely striate, with a tendency to crack longitudinally and to flake; lenticels ± absent. Leaves coriaceous, (elliptic-)oblong, 4.5-12 by 2-5 cm, base (short-) attenuate, apex rounded to subacute; upper surface drying olivaceous-brown, lower surface rufous, glabrous, but midrib remaining pubescent for some time; dense dots present; midrib somewhat raised above; nerves 5-12 pairs, thin and almost flat above, late glabrescent, lines of interarching indistinct; venation invisible on both surfaces; petiole 6-12 by 1.5-2.5 mm, late glabrescent; leaf bud 7-13 by 2-3.5 mm, with dense grey-brown to rusty hairs 0.1-0.4 mm. Inflorescences with dense rusty hairs 0.2-0.3 mm; in male: usually twice branched, not many-flowered, 2-3 by 0.5-1 cm, peduncle 1 cm long; in female: once branched, 2-3 cm long, glabrescent; bracts elliptic-oblong, 1-3 mm, pubescent, caducous; flowers in male in clusters of 3-5, perianth 3-lobed, glabrous, pedicel towards the base with hairs 0.1 mm or less, not articulated. Male flowers (submature): pedicel 1 mm long, slender; buds globose, 0.8 by 0.8-1 mm, cleft (2/3-) 3/4, lobes 0.2 mm thick; androecium (depressed-)globose, 0.4-0.5 by 0.5 mm, ± circular in cross section (Plate 3: 82); thecae 10 or 12 (see note 1), sessile, towards the apex incurved and concealing a shallow, narrow, apical cavity in the column, 0.2(-0.3) mm deep; androphore narrow, 0.1 mm long. Female flowers not seen. Fruits 2-4 per infructescence, ovoid, 2-2.3 by 1.7-1.9 cm, glabrous, finely granulate; pericarp 1.5 mm thick; fruiting pedicel 2 mm long; perianth not persistent.
