Twig to 2 mm ø apically, somewhat compressed, becoming smooth, glabrous; stipule scars short, inconspicuous. Bud3-5 by 2 mm, shortly falcate, compressed, subacute. Stipule c. 1 cm long, linear, fugaceous. Leaf 9-14 by 4-6 cm, oblong-ovate to elliptic, ± thinly coriaceous; base obtuse; acumen 8-15 mm long; nerves 12-15 pairs, slender, curved, at c. 60°-70°; tertiary nerves distant, scalariform to subreticulate; petiole 1-2 cm long, slender. Panicle to 10 cm long, terminal or axillary, slender, terete, straight, usually singly branched; bracteoles to 12 by 5 mm, lanceolate, sparsely pubescent. Flower bud to 10 by 5 mm, ellipsoid, obtuse. Calyx densely pubescent outside, sparsely so within; 3 outer lobes broadly ovate-hastate, obtuse; 2 inner lobes narrowly ovate, acuminate, slightly shorter, thinner. Petals pale yellow tinged pink at base within, large, oblong-lanceolate, obtuse, shortly pubescent on parts exposed in bud. Stamens 15, the inner 5 somewhat longer than the outer 10; filaments broad, compressed at base, tapering gradually and filiform distally; anthers narrowly oblong; appendage to connective 3-4 x length of anther, slender, scabrous. Ovary ovoid, sparsely pubescent towards apex; style c. 2 x length of ovary, distinctly trifid towards apex. Fruit calyx puberulent, ± glabrescent; 3 longer lobes to 10 by 1.7 cm, spatulate, obtuse, to 4-5 mm broad above the c. 10 by 7 mm thickened saccate base; 2 shorter lobes 5-8 by 0.7 cm, unequal and sometimes almost as long as the larger lobes, spatulate, obtuse, similar at base.
