Terrestrial or epiphytic, glabrous shrub. Branchlets angular at the tips, terete below, slender, laxly foliate, internodes unequal and sometimes not longer than 3 mm. Leaves ovate or elliptic-ovate, gradually obtusely attenuate or subacuminate towards the apex, base broadly attenuate to rounded in general, the very base suddenly contracted (2-4 mm) and bearing a thick prominent gland on each side or at the top of the petiole, stiffly fleshy when fresh, coriaceous when dry, minutely and rather laxly verruculose on both faces, (4.5-)5-8.5(-10) by (2.5-)3-4.5(-7) cm, midrib prominent on both sides, nerves in 2 basal and high curved-ascending, and 2-3 upper shorter pairs, all anastomosing and slightly raised on both faces, reticulation lax, not much conspicuous, sometimes obscure beneath; petiole subterete, 2.5-5(-6) by c. 1 mm. Fascicles 2-4-flowered. Pedicels rather slender, (3-)5-6 mm, with several minute bracteoles. Calyx tube short-cylindric, base obtuse, 1 mm, limb 4-partite, lobes ovate-triangular, 0.6 mm. Corolla subcylindric-campanulate, thin, red (possibly also white), glabrous, 2.5 mm long, 1.5-1.8 mm ø, lobes broad-triangular, obtuse, erect, 0.5-0.6 mm. Stamens 8; filaments linear, laxly hairy in front and at the margin, glabrous dorsally, nearly 1 mm; cells ovate-oblong, granular, 0.4 mm; tubules much narrower than the cells, 0.6 mm, with a large introrse pore. Disk glabrous. Style c. 2 mm, glabrous. Submature fruit 3-4 in diam., crowned by the glabrous disk and 4 suberect calyx lobes (1 mm), pale green or white. Seeds numerous, subtrigonous, 1 mm, testa reticulate.
