Scandent. Branchlets slender, sparingly hirsute with short hairs, as are the petioles. Leaves oblong to subovate-oblong, apex gradually attenuate or subacuminate, base rounded and a little oblique, very base shortly cordate, membranous, glabrous and smooth above, set with scattered hairs all over the undersurface and somewhat rough to the touch, entire, (10-)12-17 by 4-6.5 cm, midrib prominent beneath, nerves 2 basal pairs, the outer pair short, the inner one ascending to the lower third of the lamina, other higher nerves from the midrib 3-4(-5) pairs curved-anastomosing, slightly depressed above, raised beneath, reticulation coarse and faint above, a little prominent beneath; petiole (1-)1.5-2.5(-5.5) cm by 1-2 mm. ♂ Inflorescences unknown. ♀ Flowers umbellately arranged on top of a slender peduncle, the latter either solitary and axillary, or mostly 2-4 peduncles from a short thickened rachis on defoliate stem, 3-10 cm, with about 10 flowers per umbel. Calyx 4-lobed to almost the base, lobes hairy, c. 1 mm. Petals 4, greenish-yellow, fleshy, lobes elongate-oblong, subacuminate, laxly puberulous outside, glabrous inside, c. 3 by 1.5 mm, tubular basal part of the petals 5-7 mm at full anthesis. Stamens 4, flattened, very short. Ovary hairy, crowned by a thick pad-like stigma. Drupe narrowly ovoid in general, somewhat compressed, c. 2 by 1.3 by 0.8 cm, wrinkled when dry, suddenly attenuate at the very base into a kind of stipe (5-8 mm), on the base of which the lobes of the petals persist for some time; flower-axis below these lobes 6-8 mm, slightly more slender than the basal stipe of the drupe; exocarp thin, densely hairy; endocarp thin, coarsely foveolate outside, finely tubercled inside.
