Very tall, buttressed tree. Twig, bud, petiole and stipule persistently shortly evenly pale rufous pubescent, leaf nervation beneath sparsely so, glabrescent. Twig c. 1 mm ø apically, slender, much branched, at first frequently rugulose. Stipules to 3 by 1 mm, narrowly elliptic, acute, fugaceous. Leaves pink when opening, 5-13 by 2-6 cm, ovate, chartaceous, undulate; base broadly cuneate to obtuse; acumen to 1.5 cm long; nerves 7-9 pairs, slender but prominent beneath, at 50°-65°; tertiary nerves subreticulate; midrib somewhat depressed above, prominent beneath; petiole 8-12(-16) mm long, short. Panicle to 10 cm long, terminal or axillary, terete, densely persistently buff to pale rufous pubescent; singly branched, branchlets to 2 cm long, bearing to 6 ± distichous flowers; bracteoles to 2 by 1 mm, oblong, obtuse, shortly pubescent, fugaceous. Bud to 5 by 3 mm, lanceolate. Sepals ovate, shortly densely pubescent on parts exposed in bud; outer 3 acute, inner 2 shortly acuminate, relatively broader, shorter, thinner at the margin. Petals cream with a pink base, narrowly oblong, strongly contorted, sericeous on parts exposed in bud. Stamens 15, in 3 unequal verticils, the longest reaching the style apex; filaments compressed and gibbous at base, tapering and filiform below the small broadly ellipsoid anthers; appendage to connective somewhat longer than anther, slender, glabrous. Ovary ovoid, densely pubescent; style columnar, pubescent in the basal 1/2, otherwise glabrous. Fruit pedicel to 2 mm long, slender. Calyx shortly sparsely pubescent; 3 longer lobes to 9 by 2 cm, spatulate, obtuse, c. 4 mm broad above the to 10 by 6 mm ovate saccate thickened tuberculate base; 2 shorter lobes to 6 by 0.5 cm, narrowly spatulate, acute, similar at base. Nut to 1.8 by 1.2 cm, narrowly ellipsoid, densely buff pubescent, acute.
Can be grown by seedlings. Seeds needs soaking.
