Climbing shrub, apparently small, the slender, terete branchlets 1.5-3 mm ø, glabrous, laxly foliate. Leaves broad-elliptic to subobovate-elliptic, rounded, or rarely slightly retuse at the apex, broadly attenuate towards the base, the very base subtruncate-obtuse, bearing a pair of rather thickish, not much prominent marginal glands, coriaceous, laxly set with epidermal tubercles beneath, revolute particularly towards the base in dry specimens, (4.5-)6.5-9.5 by 3-5 cm, 5-7-plinerved from and a little from above the base, midrib broadened for the lowest c. 5 mm, abruptly narrowed upwards, prominent on both sides as are the nerves, the inner pair of nerves high ascending and anastomosing a little below the top of the lamina, veins lax, irregularly transverse, rather numerous, somewhat prominent above, less distinct beneath; petiole transversely rugose, 2-4 by 1.5-2 mm. Flowers from the upper axils, solitary or more rarely in twos, glabrous in all outer parts. Pedicels slender, 0.9-1.5 cm, with 2 or 3 bracteoles (1 mm). Calyx tube subcylindric-obconical, 1 mm; limb campanulate, 1.5 mm, 4-lobed halfway, lobes depressed-ovate, apiculate. Corolla narrow-cam-panulate, thin, pink, 5 mm long, 4-partite ± halfway in full anthesis. Stamens 8; filaments laxly ciliate, hardly 2 mm; cells narrow-oblong, 1.5 mm; tubules slender, slightly divergent, 1.5 mm. Disk glabrous. Style glabrous, 4.5 mm. Immature fruit with 4 inflexed calyx lobes; fruit-pedicel 1.5 cm.
