A sprawling woody climber, sometimes epiphytic, rooting adventitiously, up to 6 m; stem 2-3 cm ø. Branchlets subterete, initially short-pubescent, early glabrescent. Leaves scattered, ovate to ovate-rounded, apex blunt or rarely subacute, base broad and rounded, or sometimes cordate, thick-coriaceous, glossy green above, paler and dull below, with a faint, early disappearing puberulence on both faces, shining especially above, laxly set with dark glandular and somewhat impressed points (the bases of +-early fallen subsetose brownish hairs) underneath, entire, edge much recurved when dry, (2.5-)4-7.5 by (2-)2.5-4(-5) cm, midrib strong, +-deeply immersed above, obtusely prominent below, nerves 5 pairs, the lower 2 basal or subbasal and more conspicuous than the higher ones, all curved, whether or not +-sulcate on the upper surface and prominent beneath, reticulation mostly indistinct, but sometimes +-raised beneath; petiole reddish, rugose as the lower part of the midrib above, 6-12 by c. 2 mm. Flowers red or pink, c. 2.5 cm long, (1-)few(-5) together in an axillary or subterminal fascicle or a short-axed corymb, sparsely grey-pubescent and with many setulose gland-tipped hairs, sometimes glabrescent. Pedicel reddish, thick, much broadened and nearly cup-like below the calyx, continuous with the latter, 1.5-2.5 cm, with 2 narrow ovate-acuminate bracts 3-4 by 1 mm at base. Calyx reddish, 5-angular or shortly 5-winged, tube ± conical, inflated at base, narrowed distally, 0.8-1 by 1.5-1 cm, limb tubular, ± erect, subcoriaceous, 1.2-1.5 cm high, lobed to 1/2-2/3, lobes broad, acute, 5-6 mm wide at base. Corolla elongate-urceolate, the lower third included by the calyx lobes, fleshy, glossy carmine red outside, dull (almost glaucous-)carmine inside, base whitish, densely set outside with rufous, crisp, gland-tipped hairs in the upper half, glabrous inside, c. 2.6 by 1.3 cm in fresh specimens, dropping together with the stamens very early, lobes (2 mm) reflexed. Filaments laxly rufous-pubescent, 3-4 mm; anther-cells narrow-oblong, very granular, 5-6 mm; tubules bent aside, narrow, (4-)5-6 mm, opening by slits in the upper part. Style columnar, glabrous, 2 cm. Disk glabrous. Fruit subglobose, winged, red, waxy, shiny, crowned by the large calyx limb. Seeds compressed ovate-ellipsoid, 1-1.5 mm.
