Tree 15-25 m. Twigs 4-10 mm diameter, early to rather late glabrescent, hairs dark rusty, 0.5-1.2 mm; bark finely striate or not, not flaking, lenticels usually present. Leaves coriaceous, elliptic to oblong-lanceolate, 14-35(-40) by 4—10.5(—13) cm, base rounded or short-attenuate, apex acute-acuminate, often to 2(-3, in sapling shoots) cm caudate; upper surface drying dull olivaceous-brown, minutely rugose-pustulate, lower surface late glabrescent or with persistent ± evenly sized, spaced, rather harsh, dark brown hairs 1-1.5 mm long, when shed rough with thickened hair bases; dots absent; midrib ± flat above, late glabrescent, but indumentum usually persistent towards base; nerves 11-30 pairs, ± straight, 50-70° to the midrib, 5-15 mm apart, thin and sunken above, lines of interarching regular and prominent; venation lax, sunken and clearly visible above, giv-ing the blade a ± bullate appearance; petiole 2-12 by 2.5-4.5 mm, not or hardly winged; leaf bud stout, 3-6 cm long, with harsh hairs 1-1.5 mm long. Inflorescences with woolly hairs 1-1.5 mm long, 2 or 3 times branched, rather many-flowered; in male and female: 4-10 by 2-9 cm, peduncle up to 1.5 cm long; bracts (broadly) ovate, acutish, 3-5 mm long, caducous; flowers ± solitary (in female) or in loose clusters of 2-6, perianth 2-lobed, with stellate(-dendroid) hairs 0.1-0.3 mm, pedicel slender, with coarse hairs 0.4-0.7 mm, not articulated. Male flowers: pedicel 2-3.5 mm long; buds somewhat com-pressed, in lateral view subcircular, 1.5-3 by 3-4 mm, the basal part thick and coriaceous, the remainder collapsed when dry and perianth then often saucer-shaped or wrinkled, above the anthers opening by a minute pore-like slit less than 1 mm wide; lobes and apical part of perianth 0.2(-0.4) mm thick; androecium consisting of a coriaceous ± el-lipsoid column 0.8-1.1 mm long, with 2 small anthers, each 0.2(-0.3) mm at the apex (Plate 2: 36). Female flowers: pedicel (1.5—)3—5 mm long; buds broadly ellipsoid-ovoid, 3.8-4 by 3.5-4 mm, cleft 1/5-1/10, with a minute pore-like slit above the stigmas; ovary ovoid-subglobose, 2.5-3 by 2.5 mm, with dense hairs 0.1-0.3 mm; style erect, glabrous, 0.2-0.8 mm long; stigma 2-lobed, 0.2-0.3 mm long. Fruits 3-10 per infructescence, ellipsoid, apex acute, sometimes acuminate, 3-5 by 2-3 cm, minutely pubescent at least at the base, pericarp woody-coriaceous, 4-7 mm thick, usually with paler, small or coarse lenticels or tubercles; fruiting pedicel 2-7 mm long; perianth not persistent.
