Large buttressed tree. Twig, bud, stipule outside, petiole and leaf nervation beneath densely persistently pink-brown scabrid tomentose; stipule inside and nervation above sparsely, midrib above densely evenly so. Twig c. 2 mm ø apically, terete, smooth; stipule scars short, horizontal, obscure. Bud to 4 by 3 mm, ovate, compressed, acute. Stipule to 10 by 5 mm, lanceolate, acute, caducous. Leaves 9-16 by 3.5-7 cm, chartaceous, undulate, the lower surface markedly concave; base broadly cuneate to obtuse; acumen to 8 mm long, short, broad; nerves 17-20 pairs, slender but prominent beneath, at 40°-60° (to 100° at the base); tertiary nerves densely scalariform, at 90° to midrib, applanate above, prominent beneath; petiole 10-18 mm long, slender. Panicle 20 cm long, terminal or axillary, terete, slender, ascending, lax, densely shortly unevenly persistently pale pink-brown pubescent; singly branched, branchlets to 2.5 cm long, bearing to 10 distichous flowers; bracteoles to 5 by 3 mm, elliptic, obtuse, yellow-brown puberulent, persistent until the formation of young fruit. Flower bud to 7 by 3 mm, lanceolate, small. Sepals pubescent on parts exposed in bud; 3 outer deltoid, acute, 2 inner ovate, acuminate, smaller. Petals lanceolate, hirsute on parts exposed in bud. Stamens 15, in 3 unequal verticils; filaments compressed at base, abruptly tapering medially and filiform below the subglobose anthers; appendage to connective slender, glabrous, c. 3 x length of anther. Ovary ovoid, pubescent; style filiform, to 1.5 x length of ovary, pubescent in the basal 1/3. Fruit pedicel to 3 mm long, prominent. Calyx pale yellow-brown pubescent at base, glabrescent distally; 3 longer lobes to 14 by 2.5 cm, broadly spatulate, obtuse, c. 8 mm broad above the to 13 by 12 mm ovate thickened saccate base; 2 shorter lobes to 8 by 1 cm, lorate, obtuse, similar at base. Nut to 2 by 1.5 cm, ovoid, very shortly mucronate at the otherwise obtuse apex, shortly evenly pale buff pubescent.
