Stiff, scandent, sparsely branched shrub, also epiphytic, 1-2 m. Branchlets subterete, tips puberulous, older parts early glabrous and covered with cork. Leaves ovate or oblong-ovate, apex rather shortly (1-2 cm) subcaudate-acuminate, ± acute and subfalcate, base broadly rounded, slightly inequilateral, coriaceous, rigid, dark green, glabrous except some very short, appressed, redbrown, glandular hairs or their bases beneath, entire, (5-)7-12 by (3-)3.5-6.5 cm, midrib and nerves +-strongly impressed above, prominent beneath, 3 pairs of main nerves from or from above the base, the outer pair immediately along the margin and much less distinct, all curved-ascending to the apex, inarching with higher nerves and veins, reticulation rather coarse, raised on both faces, or faintly impressed above, prominent beneath; petiole short-pubescent initially, early rugose or corky, 5-6(-8) by 1.5-2 mm. Flowers (1-)2-3 from upper axils, but said to be borne on old wood also. Pedicels dark red when fresh, rather robust, glabrous or with sparse short-stalked reddish glands, more densely so immediately below the calyx, 1-1.5(-2) cm. Bracts small. Calyx tube obconical, base subtruncate, distinctly 5-ribbed, laxly white-hairy, 5-6 mm long, limb completely 5-lobed, lobes deltoid, acute, 2 mm. Corolla urceolate, +-5-angular, +-fleshy, pale red at the tube, cream or white at the lobes, laxly whitish hairy at least in the upper part and predominantly so at the angles, moreover with lax brown, subappressed, glandular hairs all over outside, glabrous inside, 8-9 by 5-6 mm including the suberect lobes, 1 mm. Stamens nearly as long as the corolla; filaments glabrous, 2-2.5 mm; anther-cells very granular, ± recurved at base, 3-3.5 mm; tubules narrow, 2-2.5 mm, dehiscing by slits nearly to the base. Disk glabrous. Style 8 mm.
