Young twig, petiole, raceme, midrib, nerves and sometimes tertiary nerves beneath sparsely shortly rust pubescent, mostly caducous; leaf bud and stipule outside densely persistently so, the hairs longer, pinkish buff. Twig 3-5 mm ø apically, glabrous, smooth but for the paler amplexicaul stipule scars, occasionally rugulose. Bud 5-7 by 2.5-3 mm, ovoid, subacute. Stipule to 40 by 4-5 mm, linear, acute. Leaves 7-12 by 3-7 cm, broadly ovate to elliptic; base obtuse or broadly cuneate; acumen to 8 mm long; nerves 9-12 pairs, distant, at 50° at the lamina base, down to 20° at the apex, prominent; margin frequently undulate towards the apex; petiole 1.5-2.5 cm long, slender. Raceme to 6 cm long, singly or rarely doubly branched, terminal or axillary, terete or +-compressed; bracteoles unknown. Flower bud to 4 by 1 cm. Calyx and corolla typical, calyx glabrous. Stamens c. 25, shorter than the style; anthers short, narrowly sagittate; appendage stout, tapering, c. 1/2 length of anther. Ovary conical, shortly densely pubescent; stylopodium and style c. 3 times length of ovary, densely tomentose except at apex, slightly swollen medially. Fruit calyx tube to 1.5 by 1 cm, narrowly ovoid to ellipsoid, tapering gradually into the pedicel and to the c. 8 mm ø neck, with 5 narrow c. 1 mm broad, c. 6 mm, long wings in the distal half terminating at the insertion of the cayx lobes; 2 longer lobes to 7.5 by 1.5-1.8 cm, chartaceous, oblong, obtuse, ± abruptly constricted at the undulate margined base; 3 shorter calyx lobes c. 5 by 4 mm, revolute and recurved outwards.
