Liana. Twigs glabrous; branchlets (yellowish) brown, smooth or scabrous by many small lenticels. Leaves oblong or elliptic-oblong, 7.5-9.5 by 3-4 cm, chartaceous, glabrous, base cuneate, slightly attenuate, apex gradually to caudate acute-acuminate, acumen up to 1.5 cm; 3-5-plinerved, nerves diverging at or slightly above the base, distinct, not far from the margin, venation dense, transverse; petiole 6-7 mm. Inflorescences axillary, 2-7 cm long, larger ones long-peduncled and with a pair of strong branches at the base, laxly branched, relatively few-flowered, at least the terminal parts fairly densely rusty tomentose. Calyx 1.5-1.75 mm, inside sometimes at the base with a line of erect hairs, sepals ovate, rounded to nearly truncate. Corolla c. 9 mm long, halfway connate, very thin, outside glabrous, inside densely woolly from slightly above the base to about halfway the lobes, most densely so in the mouth. Stamens inserted in the mouth, filament 1.25-2.5 mm long, glabrous, anthers elliptic to lanceolate, 1.25-1.75 mm long, minutely apiculate, glabrous or with a few hairs at the base of the cells. Pistil 8-9 mm, fairly densely shaggy short-hairy from about halfway the ovary upwards. Fruit (possibly not quite normal and galled!) on a strongly thickened branch, globular, c. 2 cm ø, slightly scabrous. Seeds unknown.
