Large pale barked frequently buttressed trees. Twigs, leaf buds, stipules outside, petioles and base of inflorescence densely ± persistently evenly long rufous-tomentose, becoming distinctly tufted as the twigs and stipules expand; nerves and midrib beneath and inflorescence sparsely evenly puberulent. Twigs c. 6-10 mm ø, terete. Leaf buds to 9 by 1.3 cm, lanceolate; stipules to 20 by 3 cm, lorate. Leaves 15-25 by 7.5-12 cm (to 40 by 20 cm in young trees), elliptic-oblong to ovate, coriaceous; margin undulate, prominently sinuate distally; base cuneate to obtuse (narrowly peltate in young trees); apex acute to prominently narrowly acuminate, to 1 cm long; nerves 22-28 pairs, straight, ascending at c. 50°, slender but prominent beneath, +-shallowly depressed above; tertiary nerves densely scalariform, very slender, evident but hardly elevated beneath; midrib prominent beneath, +-elevated above; petiole 3.5-5 cm long, prominently geniculate. Raceme to 14 cm long, +-unbranched, axillary, bearing to 7 flowers. Flower buds to 30 by 9 mm; stamens c. 30, slightly shorter than style at anthesis; filaments slender, c. 1/2 length of filiform auriculate tapering anthers; appendage acicular, slender, c. 3/4 length of anthers; ovary small, ovoid, hirsute as also the basal 1/2 of style; style stoutly columnar, c. 4 times length of ovary. Fruit pedicel expanding into the to 4 by 3.5 cm smooth turbinate calyx tube; 2 longer lobes to 25 by 3.5 cm, lorate-spatulate, obtuse, c. 5 mm broad at base; 3 shorter lobes to 6 by 6 mm, suborbicular, small, +-recurved.
