Terrestrial or epiphytic shrub, rarely over 5 m. Branchlets terete, greyish, subpatent-pubescent in the younger reddish parts, glabrescent and early corticate. Leaves ovate to lanceolate-ovate, apex shortly or more longish acuminate, blunt or nearly so, base mostly rounded or broadly attenuate, subcoriaceous, +-stiff, lower part of midrib above with lax rather longish white hairs as are margin, midrib and nerves beneath at least in young leaves, glabrescent, furthermore beneath with lax short glandular subsetulose caducous hairs or finally glandular-punctulate, edge minutely glandular-crenulate or-dented, very edge ± recurved (dry), 1.5-4.5 by 0.8-1.5 cm, midrib slightly impressed above, prominent beneath, nerves c. 5 pairs, lower 2 curved-ascending from or +-from base, other ones higher up and more spreading, all inarching, whether or not impressed above, raised beneath as is the lax reticulation; petiole red, +-slender, hairy, 2-3 mm. Flowers from the upper axils 1—2(-3) in fascicles. Pedicels red, stoutish, glabrous or laxly patently white-hairy, bibracteolate at or slightly above the base, 1.2-1.8 cm. Calyx narrow-obconical at anthesis, becoming inflated later, red, manifestly 5-ribbed, glabrous, (8-)9-10 by 3-4 mm including limb, the latter low, 5-lobed to base, lobes ovate-deltoid, acute, 1.5-2 mm. Corolla cylindrical, 5-angled, +-fleshy, glabrous, pale green or greenish white, (3-)3.5-4 by 0.5-0.6 cm including the deltoid, erect lobes, 2-2.5 mm. Stamens +-as long as the corolla; filaments linear, glabrous, 12-15(-16) mm; anther-cells granular, (6-)8-9 mm, +-unequal; tubules rather broad, (9-)12-14 mm, splitting in the upper 1/2 to ⅔. Style slender, glabrous, equalling the corolla. Disk glabrous. Submature still green fruit oblong-ellipsoid, 5-ribbed, 9-10 by 6-7 mm, sepals inflexed.
