Very large tree. Young parts evenly densely pale golden pubescent, fugaceous except on stipule, panicle, sepals and parts of petals exposed in bud; leaf undersurface and petiole persistently pinkish to cream lepidote (young tree excepted). Twig c. 4 by 3 mm towards apex, stout, somewhat compressed, becoming smooth to slightly rugulose, terete, pale brown; stipule scars short, horizontal, obscure. Buds to 4 by 3 mm, broadly ovoid, acute. Stipules to 4 by 3 mm, ovate, obtuse, caducous. Leaves 7-18 by 4.5-8 cm, ovate to elliptic, thickly coriaceous; base broadly cuneate to obtuse; apex obtuse, acute or with to 1 cm long stout acumen; nerves 15-20 pairs, slender, rather straight, at to 90° at the base, to 50° near the apex; secondary nerves slender, subreticulate; midrib obscure and depressed above, prominent and terete beneath; petiole 2-4 cm long, terete, stout. Panicles to 20 cm long, terminal or axillary, somewhat compressed, singly branched; branchlets to 7 cm long, lax, bearing to 4 flowers; bracteoles unknown. Flower bud to 10 by 5 mm, lanceolate.

Can be grown by seedlings. Seeds needs soaking.
