Small tree. Vegetative parts at first densely pale tawny pubescent, caducous first on lamina, nervation beneath, petiole and then twig, persistent on buds and stipules. Twig c. 2 mm ø apically, becoming smooth, glabrous. Bud to 2 by 1 mm, ovoid, acute. Stipule to 4 mm long, linear, caducous. Leaves 12-28 by 5-9 cm, oblong-lanceolate to oblanceolate; base obtuse to subcordate, unequal, the larger side adjacent to the twig; acumen to 2 cm long, subcaudate; margin somewhat revolute; nerves 12-21 pairs, slender, scalariform, diagonal to midrib and nerves; midrib prominent on both surfaces, more so beneath than above; petiole 3-8 mm long, short, stout. Panicle to 8 cm long, terete, glabrous, slender, frequently fasciculate, frequently borne up the branches behind the leafy twigs; singly branched, branchlets bearing to 8 secund flowers. Flower bud to 3 by 2 mm, ellipsoid. Calyx glabrous, 2 outer sepals lanceolate, acuminate, 3 inner suborbicular, somewhat shorter, shortly mucronate. Petals linear, pubescent on parts exposed in bud.

Ovary narrowly ovoid, glabrous, surmounted by a spindle-shaped glabrous stylopodium and style somewhat shorter than the ovary in length. Fruit glabrous. Pedicel to 1 mm long, short. 2 longer calyx lobes to 10 by 1.5 cm, spatulate, chartaceous, c. 4 mm broad above the to 2 cm long, to 7 mm wide paired basal auricles, with a to 5 by 4 mm central basal ovate saccate thickened area; 3 shorter lobes to 3 cm long, with up to 12 by 4 mm tapering subacute lobe above a similar base.
