Epiphytic or terrestrial creeping shrub, small, the slender not branched stems coming from a woody stock, glabrous in all outer parts, laxly foliate. Leaves elliptic to ovate-elliptic, apex obtuse or rounded, never retuse, base very broadly attenuate or mostly ± rounded in general, the very base suddenly contracted for 2 mm and bearing there or almost at the apex of the petiole a conspicuous somewhat prominent gland on each side, light green and rather thickly coriaceous when fresh, thinly so when dry, flat, 6-7.8 by 3-4 cm, 5-7-plinerved from and a little from above the base, sometimes with 1 or 2 similarly curved-ascending nerves inserted higher on the midrib, all anastomosing and slightly prominent on both faces, veins ± transverse, forming with the veinlets a rather dense, not much raised reticulation; petiole rugulose, 4-5 by 1 mm. Flowers solitary. Pedicels slender, 0.8-1 cm, the 2 bracteoles ovate-acuminate, c. 1 mm. Calyx tube narrowly cup-shaped, c. 1.5 mm, limb suberect, broadly acutely 5-dented, 0.7 mm. Corolla subcampanulate, 5-partite to almost the base, thin, c. 6 mm, lobes erecto-patent, ovate-oblong, subacute, nerved. Stamens 10; filaments ciliolate, 2.5 mm; cells elongate-oblong, minutely granular or papillose, 3 mm; tubules elongate-cylindric, minutely verruculose below, c. 2 mm. Style glabrous, 5 mm.
