Large semi-deciduous tree. Leaf bud and parts of petals exposed in bud persistently cream pubescent, calyx and ovary thus at first, becoming sparsely pubescent; parts otherwise sparsely fugaceous puberulent, glabrescent. Twig 2-3 mm ø apically, smooth, pale brown; stipule scars short, pale, slightly down-curved. Leaves 7.5-15 by (2-)2.5-6 cm, elliptic-oblong, thinly coriaceous; base obtuse; apex shortly acuminate or retuse; nerves 13-20 pairs, very slender, elevated on both surfaces, arched, at 60°-70°; tertiary nerves scalariform, evident on both surfaces; midrib slender but prominent and terete beneath, obscure and depressed above; petiole (13-)20-30 mm long, slender. Panicles to 10 cm long, lax, slender, terminal or axillary; singly branched, branchlets to 8 cm long, bearing to 6 distant secund flowers; flower buds to 6 by 4 mm, broadly ellipsoid; 3 outer sepals ovate-elliptic, acute; 3 inner smaller, ovate, acute; stamens 25, filaments broad and compressed at base, gradually tapering; appendages filiform, villous in the distal 1/2, c. 1.5 times length of the narrowly oblong tapering anthers; ovary narrowly ovoid, tapering into the equally long columnar deeply trifid style. Fruit pedicel to 4 mm long, expanding into the base of the nut; 3 longer calyx lobes to 14 by 2 cm, spatulate, obtuse, c. 8 mm wide above the 18 by 14 mm elliptic saccate thickened base; 2 shorter lobes to 10 by 0.7 cm, slender. Nut to 3 by 1.5 cm, ovoid, glabrous, tapering to the prominent style remnant.
Can be grown by seedlings. Seeds needs soaking.
