Tree 10-40 m. Twigs subterete or ± angular, l-2(-2.5) mm diameter, early glabrescent, hairs 0.1—0.5(—1) mm; older twigs sometimes becoming longitudinally cracked or slightly flaking; lenticels not conspicuous. Leaves chartaceous, ovate-oblong to oblong-lanceolate, 8-20 by 2.5-7 cm, base cuneate or ± rounded, apex acute-acuminate (very tip often ± blunt); upper surface olivaceous or brown, lower surface pale, glabrous; papillose; dots absent; midrib somewhat raised above, lateral nerves 8-14 per side, at 60-70° to the midrib, flat or sunken above, not much raised and sometimes hardly visible below, lines of interarching faint, venation little raised, faint or contrasting below; petiole 8-15 by 1-2 mm; leaf bud 8-12 by 2-3 mm, hairs 0.1-0.5 mm. Inflorescences sometimes below the leaves, glabrescent; in male: either (sub)sessile (as in Knema) or peduncle slender to 18 mm, ending in a single or forked scar-covered brachyblast, 1-5 mm, with clusters of 5-10 flowers, buds subequal in size; female inflorescences: similar, sessile or peduncle to 10 mm, 1-5-flowered; flowers with short or long hairs. Male flowers: pedicel shorter than the perianth, 2-3 mm, bracteole (sub)persistent or caducous; buds cleft 1/3-1/2; androphore (sub)glabrous or thinly pubescent, shorter than the synandrium; thecae 12-16; see further under the subspecies. Female flowers: pedicel shorter or longer than the perianth, 1.5-4 mm; buds ovoid(-ellipsoid), 3-4.5 by 2-3 mm, apex narrowly rounded, cleft 1/3-1/2, lobes 0.3 mm thick; ovary ovoid-oblong, 2-2.5 by 1(—1.5) mm, pubescent, hairs 0.1-0.2 or 0.5-0.8 mm. Fruits solitary or paired, ovoid-ellipsoid, 3-4 cm long, hairs ± long or short, brown; pericarp 3-5 mm thick; seeds not seen; fruiting pedicel 2-4 mm.
Well drained ridge forest and sloping forest; on stony, volcanic, clayey, or serpentine-derived soils; at elevations up to 600 metres.
