Description:

Description: Epiphytic shrub with stems to 2.5 m long; mature branches terete, smooth, glabrous, nitid, dark reddish-brown; twigs terete to subterete, slightly striate, glabrous, flesh-colored. Leaves subcoriaceous, elliptic, lance-elliptic, or ovate-elliptic, 7.5-14 x 2-5 cm, basally cuneate, subattenuate, or sometimes obtuse, apically short- to long-acuminate, rarely caudate-acuminate with acumen to 2 cm long, glabrous; 5(-7)-plinerved, somewhat bullate, midrib conspicuously thickened through proximal 1-2 cm otherwise impressed above, lateral nerves impressed above and raised beneath with the inner pair arising 1-2 cm above base, reticulate veinlets slightly raised on both surfaces; petiole terete, rugose, 5-10 mm long and 0.8-1.7 mm in diam., glabrous or puberulous and then glabrate. Inflorescence 5-13-flowered; rachis subterete or slightly angled, often flexuous, glabrous but glandular-fimbriate, 1-2.8 cm long and 0.7-1 mm in diam.; floral bracts caducous, oblong, obtuse, to 14 x 8 mm, glabrous but distal margins glandular-fimbriate, translucent pale green when fresh; pedicels subterete, striate, puberulent or glabrate, fimbriate, 3-7 mm long; bracteoles oblong or ovate, 0.5-1 mm long, glabrous, margins densely glandular-fimbriate. Flowers: calyx glabrous, 3-3.5 mm long; hypanthium cylindric, bluntly pentagonal when fresh but drying 5-angled, 1.5-2 mm long, basally truncate when fresh but drying slightly apophysate, glandular-fimbriate; limb erect or spreading, ca. 1.5 mm long; lobes triangular, acute, 0.5-0.7 mm long, somewhat connivent after anthesis, marginally glandular-fimbriate; sinuses narrowly obtuse; corolla subcylindric, widest below middle, glabrous, 7-8.5 mm long and 3-4 mm diam., when fresh white in the basal 3/4 and pink in the distal 1/4, lobes oblong-trianglular, obtuse, 1.5 mm long, relfexed and revolute at anthesis; stamens 5.3-5.6 mm long; filaments slightly connate at very base, marginally short-pilose, alternately ca. 1.3 mm and 2.3 mm long; anthers alternately ca. 4.6 mm and 3.3 long; thecae 1.2-1.5 mm long; style ca. 6.5 mm long;. Berry not seen.

Distribution: Endemic to Colombia, to the western slopes of the Cordillera Occidental (Nariño Dept.), where it occurs in moist forest and along forest edge, at elevations of 1050-2700 m. Flowering specimens have been collected in February and May. Rare and endangered.
