Vast buttressed tree. Young parts, twigs, buds, stipules, leaf undersurface, petiole, panicle, ovary and parts of petals exposed in bud densely persistently pale cream-brown pubescent; densely so at first on calyx, becoming sparsely so; young trees sparsely darker pubescent. Twigs 2-3 mm ø apically, ribbed and sometimes compressed at first, becoming terete, smooth; stipule scars short, pale, horizontal. Bud c. 2 by 1 mm, ovoid, obtuse; stipules to 10 by 4 mm, lanceolate, acute, ± fugaceous. Leaves (7-)9-18 by 3-7 cm (larger in immature trees), oblong-ovate, thinly coriaceous, cream below (mature trees); base obtuse to subcordate, ± unequal, apex shortly acuminate; nerves 19-23 pairs, slender but prominent beneath, +-applanate above, at c. 65°; tertiary nerves densely scalariform, hardly elevated beneath; midrib prominent beneath obscurely depressed above; petiole 8-12 mm long, slender. Panicles to 15 cm long, slender, somewhat lax, terminal or axillary; singly branched, branchlets to 3 cm long, bearing to 7 flowers. Flower buds to 6 by 3 mm, fusiform; sepals broadly ovate, the outer 3 acute, the inner 2 acuminate; stamens 15, unequal; filaments broadly compressed at base, tapering medially and filiform beneath the broadly ellipsoid anthers; appendages very slender, scarious near the apices, twice length of anthers; ovary ovoid, puberulent; style filiform, slender, twice length of ovary, glabrous. Fruit pedicel c. 1 mm long, slender; 3 longer calyx lobes to 10 by 1.5 cm, narrowly spatulate, obtuse, c. 5 mm wide above the 7 to 8 mm ovate saccate thickened base; 2 shorter lobes to 4.5 by 0.6 cm, linear, similar at base. Nut to 15 by 8 mm, ovoid, apiculate.
Can be grown by seedlings. Seeds needs soaking.
