Twig c. 3 mm ø apically, much branched, ribbed, becoming terete, smooth, dark brown; stipule scars slender, horizontal, amplexicaul. Bud to 10 by 4 mm, lanceolate, acute; stipule to 16 by 6 mm, narrowly lanceolate. Leaves 10-20 by 5-10 cm, subcoriaceous, subpersistently plicate, dull but not silvery beneath; margin frequently narrowly subrevolute; base obtuse to subcor-date, subequal (peltate in young trees and saplings); apex subacute or to 1 cm long, broadly acuminate; nerves 11-13 pairs, ascending, prominent beneath, somewhat arched; tertiaries densely scalariform, evident and slightly elevated beneath; midrib stout and prominent beneath, elevated above; petiole 15-25 mm long, c. 3 mm ø, stout, hardly geniculate. Panicle to 13 cm long, singly or doubly branched, the branchlets bearing to 3 flowers; bracts to 10 by 4 mm, lanceolate. Flower buds to 15 by 10 mm, broadly lanceolate, flowers very large; sepals narrowly deltoid; stamens somewhat shorter than style; filaments compressed, tapering; anthers oblong-linear; appendages somewhat longer than anthers, stoutly acicular; ovary small, ovoid; style columnar, c. 5 times length of ovary, stout, puberulent but for the apical 1/5. Fruit pedicel c. 3 mm long; sepals aliform, 3 longer lobes to 20 by 2.3 cm, spatulate, obtuse; 2 shorter lobes to 10 by 0.8 cm, lorate, acute; nut to 2 cm ø, subglobose, verrucose, apiculate.
