Tree 4-25 m. Twigs 2.5-4(-8) mm diameter, blackish brown, early or late glabrescent, hairs harsh, deep rust coloured, 0.3-0.6 mm; bark coarsely striate, sometimes tending to flake; lenticels coarse and conspicuously pale. Leaves (strongly) coriaceous, elliptic-oblong to oblong-lanceolate, 8-17(-26) by 3-6(-10) cm, base rounded to (short-)attenuate, apex rounded to subacute; upper surface glabrous (glabrescent), but base of midrib late glabrescent, drying olivaceous, yellowish, or dark-brown, lower surface pale brown to chocolate, not much contrasting with the upper surface; dots absent, but usually with conspicuous pale yellowish hair scars (lens!); midrib above relatively broad, raised; nerves 8-15 pairs, above sunken, flattish, or slightly raised, lines of interarching fairly regular, sometimes distinct; venation lax, indistinct on both surfaces; petiole 6-16 by 2-3.5(-4) mm, leaf bud 10-20 by 3-4 mm, with hairs 0.3-0.6 mm. Inflorescences below the leaves, with dense, shaggy hairs 0.5-1 mm long; in male: 2 or 3 times branched, not many-flowered, (1.5—)3—10 by (1—)2—5 cm, peduncle 0.5-2 cm long, the flowers in clusters of (l-)2-6; in female: ± few-flowered, 2-4 cm long; bracts broadly ovate-ellipsoid, 3-7 mm long, densely pubescent, caducous; flowers with perianth 3-(or 4-)lobed, glabrous (glabrescent), pedicel puberulous in the lower half, not articulated. Male flowers: pedicel 2-3 mm long; buds ± obovoid (immature) to ellipsoid, 2.5-3.5 by 2-2.5 mm, glabrous, cleft 1/3-1/2, slightly collapsing on drying, lobes 0.3 mm thick; androecium ± sessile, obovoid to truncate-ellipsoid, 2-2.8 by 1.4-1.6 mm, in cross section sub-triangular (Plate 3: 74); thecae 24-28, 2-2.8 mm long, almost completely sessile (anthers free at apex for only 0.1 mm or less), column with a narrow apical hollow or slit to 1/5-1/3; androphore narrow, (0-)0.1-0.3 mm long, hidden by the anthers. Female flowers: pedicel 1.5-2 mm long, basally with hairs 0.2 mm; buds broadly ovoid-ellipsoid, 2.5-3 by 2-2.5 mm, cleft 1/3-1/2; ovary ovoid-ellipsoid, 2 by 1.5 mm, glabrous, stigma 0.2 mm high, minutely 2-lobed. Fruits l-4(-8) per infructescence, ellipsoid, apex rounded to acutish, 3-4.2 by 1.6-2.4 cm, glabrous, drying grey-brown to dark brown, without or with a few tuberculate lenticels; pericarp 2-4 mm thick; fruiting pedicel 3-5 mm long; perianth not persistent.
