Shrubs to small trees, up to 10 m high, bole up to 3 m high, dbh up to 15 cm; flowering branches 1-3 mm thick, sericeous, glabrescent. Indumentum short (< 0.5 mm long) simple hairs, mainly sericeous, dark brown and yellow or yellow only. Outer bark smooth to fissured, very hard. Stipules triangular, 0.8-2 by 0.3-0.6 mm, outside hairy, inside glabrous, usually late caducous. Leaves: petiole 2-3.5 mm long, flattened above, hairy; blades ovate to elliptic, 3-25 by 1.7-8 cm, length/width ratio 2.2-3.9, papery to coriaceous, brownish green when young, generally drying light green, base shortly attenuate to cuneate, margin entire, flat, apex long acuminate, often mucronulate, upper surface glabrous except for some hairs on basal part of midrib (and nerves), lower surface somewhat hairy, mainly on venation, venation generally slightly raised above but midrib flat, raised beneath, nerves 5-7 per side. Inflorescences terminal (or subterminal when several, probably due to sympodial length growth), up to 52 cm long, green, hairy, pistillate flowers single; bracts 0.8-1.5 by 0.25-0.5 mm, glabrous inside. Buds green. Flowers 5-merous, green to white; calyx with 5 lobes, 0.8-1.3 mm deep, lobes triangular, 0.4-0.6 by 0.4-0.7 mm, glabrous inside; petals 5, elliptic, cucullate, as deep as high, 1-1.2 by 0.8-1.3 mm, 1-1.5 mm deep, glabrous, midrib strongly thickened inside, often furrowed outside. Staminate flowers 3.6-4 mm diam.; pedicel 6.3-9 mm long; stamens 10 in two whorls, of different length, filaments glabrous, c. 0.5 or 0.5-0.7 mm long, often band-like in lateral view, often S-shaped; anthers 0.4-0.5 by 0.4-0.5 mm, thecae separated, ± parallel, horizontal because of S-shape filaments, cream to light yellow; pistillode 0.7-0.8 by 0.5-1 mm diam., glabrous. Pistillate flowers 2.5-3 mm diam.; pedicel c. 0.4 mm long, elongating in fruit up to 2.5(-4) mm; ovary c. 1.2 by 1.3 mm, very shallowly 5-lobed with central furrow due to imprints of petals, 2-locular, stigmas c. 0.5 mm long, completely split several times. Fruits laterally flattened ovoid drupes, often with 2 ridges along edges, 9-9.5 by 6.2-7.2 by 5.5-7.1 mm, somewhat hairy, wall thin, woody, c. 0.4 mm thick, very light green to pale whitish green when immature. Seeds seen immature, c. 8.5 by 5.5 by 1 mm.
