Large buttressed tree with dark brown, fissured, flaky bark. Young parts at first densely dotted with minute adpressed hair tufts, fugaceous on all but stipule outside and leaf bud; stipule persistently shortly pubescent within. Twig c. 1 mm ø apically, slender, much branched, terete, rugulose or smooth, glabrous; stipule scars narrow, slightly paler at first, almost or completely amplexicaul, ± ascending. Bud to 7 by 2 mm, fulvous pale grey, lanceolate, compressed, acute. Stipule to 20 by 3.5 mm, hastate, acute, fugaceous. Leaves 6-10 by 3-5 cm (rarely much smaller in exposed places), ovate, coriaceous; base obtuse; acumen to 6 mm long; margin sometimes slightly revolute; nerves 15-18 pairs, slender, hardly or not elevated beneath, dense, at 35°-40°, curved towards the margin, sometimes with prominent axillary pore-like domatia; tertiary nerves very slender, densely scalariform, diagonal to nerves; midrib raised beneath, obscure and depressed above; petiole 1.7-3 cm long, slender, geniculate. Panicle to 11 cm long, terminal or axillary, slender, lax, +-terete, shortly densely persistently cream to pale grey pubescent; singly or doubly branched, the branchlets short, bearing to 10 secund flowers; bracteoles to 3.5 by 2 mm, ovate, obtuse, sparsely pubescent outside, glabrous within. Bud to 5 by 2.5 mm, narrowly ovoid, subacute. Calyx densely pale grey pubescent outside, glabrous within; 3 outer lobes narrowly deltoid, subacute, slightly revolute; 2 inner lobes smaller, acute, not revolute. Petals pink, oblong-lanceolate, pubescent on parts exposed in bud. Stamens 15, the inner 5 slightly longer than the others; filaments broad at base, rather abruptly tapering and filiform distally; anther oblong; appendage to connective over twice as long as anther, reaching almost to style apex. Ovary narrowly ovoid, shortly pubescent, longer pubescent towards apex; stylopodium indistinct; style filiform, somewhat shorter than ovary, glabrous but for shortly pubescent base. Fruit calyx sparsely puberulent, more densely so at base; 3 longer lobes to 6 by 1.3 cm, chartaceous, spatulate, narrowly obtuse, c. 3.5 mm broad above the c. 7 by 5 mm deltoid saccate thickened base; shorter lobes to 3 by 0.3 cm, subequal, linear, similar at base. Nut c. 20 by 8 mm, narrowly ovoid, shortly pubescent towards the apex, otherwise glabrous; style remnant acute.
