Medium-sized tree with golden brown cracked and patchily flaked bark. Outside of stipule, twig, panicle, petiole and nervation beneath persistently scabrid fulvous pubescent; more densely tomentose on leaf buds and midrib above; caducous hispid on lamina above; shortly pubescent on stipule within. Twig c. 2 mm ø apically, becoming thinly papery flaked, terete, much branched; stipule scars short, horizontal, obscured by tomentum. Bud 3-4 by 2-3 mm, broadly ovoid. Stipule to 7 by 2 mm, narrowly hastate, acute. Leaves 6.5-10 by 3-4.5 cm, chartaceous, frequently cupped, elliptic to oblong-ovate; base narrowly obtuse or broadly cuneate; apex obtuse or with to 5 mm long short acumen; margin usually revolute; nerves 10-12 pairs; tertiary nerves well spaced, scalariform, at 90° to nerves; nervation depressed above; petiole 0.8-1 cm long, short. Panicle to 11 cm long, terminal or axillary, terete, lax, regularly singly (or doubly if terminal) branched; branchlets to 3.5 cm long, bearing to 8 ± secund flowers; bracts unknown; bracteoles to 6 by 3.5 mm, broadly elliptic, obtuse, pale grey puberulent. Flower bud to 15 by 3 mm, fusiform, obtuse. Calyx small, densely pale greyish pubescent outside, glabrous within; lobes subequal, broadly ovate to suborbicular. Petals pale cream pink at base, linear, obtuse, densely pubescent on parts exposed in bud, loosely adhering on falling. Stamens 15, congested, the 5 inner longer by an anthers length, the outer 10 subequal; filaments connate at base, broad, tapering abruptly and filiform distally; anthers oblong; appendages to connective to 4 times length of anther, exceeding style apex, very slender, twisted. Ovary and stylopodium ovoid, densely shortly pubescent; style almost twice their length, the basal half thickened and setose. Fruit calyx persistently sparsely pale buff pubescent at base, glabrescent towards apex; 2 longer lobes to 9 by 1.3 cm, spatulate, obtuse, to 5 mm broad above the to 6 by 6 mm prominently saccate thickened base; 2 shorter lobes to 5 by 3 mm, linear, obtuse, similar at base.
