Description:

Description: Epiphytic shrub, sometimes lianoid, with branches to 3 m long; stem terete, glabrous, bark cracking longitudinally, grayish; twigs subterete, complanate, bluntly angled, minutely white-puberulent. Leaves coriaceous to subcoriaceous, elliptic, elliptic-oblong to narrowly ovate-lanceolate, (3-)4-6(-10) x (0.7-)1-2.5 cm, base narrowing, rounded or truncate to cordate, apex long-acuminate, acute or blunt, margin flat or usually incurved, sometimes strongly revolute, short-pilose or pale puberulent then glabrate, with few tiny scattered glandular fimbriae on both surfaces; lamina at base beneath on both sides of midrib provided with an oval or circular, reddish, impressed gland to ca. 0.6 mm diam.; 3-5(-7)-plinerved from near base, midrib strongly impressed above and raised beneath, lateral nerves and reticulate veinlets conspicuously raised or slightly impressed on both surfaces; petiole terete or somewhat flattened above, rugose, 1.8-5 mm long, glabrous or weakly puberulent. Inflorescence axillary, racemose, 5-12-flowered, surrounded by few, lanceolate, sparsely puberulent bracts, 3-5 mm long; rachis complanate, thin, bluntly angled, 5-11 cm long, densely white-puberulent; floral bract membranous, lanceolate to ovate-lanceolate, acuminate, 3-5 mm long, ciliolate; pedicel subterete, ribbed, 6-12 mm long, puberulent, sometimes glandular-fimbriate apically; bracteoles located below middle of pedicel, opposite to subopposite, similar to floral bract, but 1.5-2.3 mm long. Flowers with calyx sparsely puberulent to glabrous, 4-6 mm long; hypanthium turbinate-campanulate, obconic, 5-winged opposite sinuses, 3-3.5 mm long, sometimes bearing scattered glandular fimbriae; limb erect-spreading, 1.5-2 mm long; lobes triangular to elongate-deltate, 1.5-2.5 mm long, the tip weakly ciliolate; sinuses acute; corolla ng-conical in bud, cylindric-urceolate at anthesis, conspicuously winged opposite the lobes, 7-9 mm long, greenish-yellow, the wings broadest near base (to ca. 1 mm) narrowing distally, with scattered glandular fimbriae, the lobes narrowly long-triangular, acuminate, 2-3 mm long, strongly recurved and curled at anthesis exposing stamen; stamen alternately slightly unequal, 6.6-8 mm long; filaments distinct, 1-1.5 mm long, glabrous; anthers alternately ca. 7.3 mm and 6.5-7.5 mm long, slightly prolonged at base; thecae 1.5-2.5 mm long; tubules alternately 4.5-5.2 mm and 4.2-4.8 mm long, dehiscing by short, oblique clefts, 0.5-0.7 mm long; style about as long as corolla, glabrous; nectariferous disc annular, glabrous. Berry not seen.
