Trees 10–30 m tall, dbh 5–30 cm; bark grey to brown or red-brown, smooth or flaking into irregular small flakes; inner bark red to yellow brown; sapwood (pale) yellow or cream. Twigs slender, 2.2–3 mm diam, brownish, velutinous; terminal leaf buds lanceolate, 5–9 mm long, velutinous; hairs short, straight, appressed, light brown. Leaves alternate to subopposite, blades elliptic to lanceolate, (6.5–)9–31 by (2–) 3–13 cm, leathery, bright to dark green; apex blunt or acuminate; base cuneate; margins flat to recurved; secondary veins 9–13 pairs, curving and join near margins; tertiary veins reticulate to scalariform; upper surface glabrous, shiny, (dark) green when fresh, midrib sunken and velutinous, secondary veins sunken, tertiary veins distinct; lower surface sparsely to slightly hairy, pale green when fresh, drying brownish, midrib raised, densely hairy, secondary veins raised, tertiary veins distinct. Petiole 9–25 mm long, channelled to half terete, slender to swollen, sparsely hairy to velutinous. Inflorescence 35–160 mm long, not enclosed at base by bracts, velutinous, red; bracteoles linear, 0.5–5 mm long. Flowers hairy, green, cream or white to deep yellow; perianth tube c. 1 mm long, densely hairy; perianth lobes elliptic, 1.5–2 by 0.9–1.3 mm, apices rounded to acute, densely hairy. Stamens 9, 0.7–1.7 mm long, anthers about as long as filaments, yellow. Ovary c. 1 mm diam, glabrous; style c. 1 mm long.
