Erect shrub or tree 2-20 m. Twigs (l-)2-4 mm diameter, sometimes ± angular, at first with rough, rusty, grey-brown, or yellowish brown hairs 0.5-2 mm long, glabrescent; bark striate or fissured, cracking, later on coarsely or finely flaking, or not. Leaves membranous or thinly coriaceous, oblong to (ob)lanceolate (broadest below the middle in subsp. latericia), 8-30 by 1.5-9 cm, apex acute(-acuminate), base attenuate to rounded, drying brown or greenish above; lower surface glabrous, grey(-brown) or whitish, not obviously papillate; dots absent; midrib raised above (when dry reddish in subsp. ridleyi, pale brown or whitish in subsp. albifolia); nerves 9-25(-30) pairs, raised; venation faint or distinct; petiole (5—)10—18 by 1.5-3.5 mm. Inflorescences: sessile, brachyblast simple, warted or furcate, up to 10 mm long, in male 3-20-flowered, female 2-10-flowered; flowers with pale brown to rusty hairs 0.2-0.7 mm long; perianth 3-(or 4-)lobed, red inside. Male flowers: pedicel 2-6 mm long, bracteole caducous, median to subapical; buds depressed obovoid (subsp. albifolia) or depressed globose, 3-3.5 by (3-)4-4.5 mm, cleft 2/3-4/5, lobes 0.5(-l) mm thick; staminal disc circular, flat, ± convex, or low-mammillate, 2 mm diameter; anthers 9-12, shortly stiped, 0.5 mm long, horizontal, not touching; androphore 1 mm long. Female flowers: pedicel to 1.5 mm long, bracteole subapical; buds much larger than in male, obovoid, 5-8 by 4-5 mm, cleft 1/3-2/3, lobes 0.5-1 mm thick; ovary subglobose to ovoid, 2.5-3 mm long; the stigma subsessile, ± 2-lobed and each lobe again deeply (3-)4-6-serrate. Fruits 1-4 per infructescence, broadly ellipsoid to obovoid, sometimes subglobose, apex rounded, (l-)1.5-3 by 1-2.5 cm, with rough hairs 1-2 mm long; dry pericarp (l-)2-3 mm thick, the fruiting pedicel 2-5 mm long.
