Characteristics

Tall buttressed tree. Twigs, petioles, buds and stipules outside (sparsely within) densely shortly evenly persistently golden-tawny pubescent, leaf nervation beneath sparsely caducously so. Twig c. 2 by 3 mm ø apically, somewhat compressed, rugose when dry, becoming smooth, terete; stipule scars short, dark, slender, horizontal. Bud to 3 by 2 mm, ellipsoid, obtuse. Stipule to 15 by 4 mm, narrowly elliptic to falcate, subacute, caducous. Leaves 8-13 by 3-6.5 cm, elliptic, coriaceous; base broadly cuneate; acumen to 1 cm long, broad; nerves 10-14 pairs, very prominent beneath, applanate or depressed above with the lamina bullate between them, at 85° at the base, 40°-55° towards the apex; tertiary nerves slender, densely scalariform; midrib prominent beneath, somewhat depressed above; petiole 11-20 mm long, drying rugose. Panicle to 5 cm long, terminal or axillary, short, rugose when dry, persistently evenly shortly golden-tawny pubescent, branchlets bearing to 3 flowers; bracteoles fugaceous. Flower bud to 10 by 3 mm, fusiform. Calyx shortly densely pubescent on parts exposed in bud, the inner 2 lobes fimbriate distally; lobes ovate, acute, the inner 2 somewhat smaller than the outer 3. Petals cream, pale carmine at base, linear, shortly densely pubescent outside, sparsely sericeous within. Stamens 32-41; filaments comparatively densely setose, compressed at base, tapering distally; anthers narrowly oblong, sparsely setose on the distal margin, the 2 outer cells somewhat the larger; appendage to connective hardly exceeding anther apex, densely setose. Ovary ovoid, densely pubescent, surmounted by a similarly tomentose narrowly conical stylopodium and glabrous filiform style; style as long as ovary and stylopodium. Fruit pedicel and base of calyx lobes outside sparsely pubescent, nut densely evenly shortly persistently buff pubescent, fruit otherwise glabrous. 3 longer calyx lobes to 10 by 2.5 cm, broadly spatulate, obtuse, to 7 mm broad above the to 15 by 12 mm ovate thickened saccate base; 2 shorter lobes to 8 by 1 cm, linear, acute, similar at base. Nut to 2.5 by 1.4 cm ovoid; stylopodium to 6 mm long, prominent.
