Description:
Species Description - Lianoid shrub, 2-3 m long; stem terete, striate, glabrate; bark grayish-brown, cracking longitudinally; twigs subterete, bluntly angled, striate, white puberulent, glabrate. Leaves coriaceous, ovate to elliptic, 3-10 x 1.5-3.8 cm, base obtuse or rounded and shallowly cordate, apex tapering and acute to short acuminate, marginy entire, glabrous on both surfaces although glandular-fimbriate beneath; 5(-7)-plinerved from near base, midrib, lateral nerves, and reticulate veinlets shallowly impressed above and raised beneath causing the leaves to be slightly bullate; petiole subterete, flattened and puberulent above, rugose, 3-6 mm long. Inflorescence axillary, racemose, 10-22-ered; rachis subterete, complanate to bluntly angled and ribbed, 6-21 cm long, densely and persistently puberulent; floral bract membranous, ovate-lanceolate, long-acuminate, 5-6 mm long, weakly puberulent, densely ciliolate, marginally with few caducous glandular fimbriae; pedicel subterete, striate, 14-22 mm long, puberulent, scattered glandular-fimbriate distally; bracteoles near base, similiar to floral bract but 3-4 mm long. Flowers with calyx 7-8 mm long; hypanthium obconic, strongly bluntly 5-winged with scattered glandular fimbriae, 4.5-5 mm long, weakly puberulent along edges of wings; limb erect, 3-3.5 mm long; lobes triangular, acuminate, 2-2.5 mm long, ciliolate; sinuses rounded; corolla cylindric-conical in bud, cylindric-urceolate at anthesis, ca. 15 mm long, broadly 5-winged at base, the wing 1.5 mm broad becoming narrowly winged to the tips of the lobes, greenish-white, the lobes ca. 9 mm long, completely reflexed and curled back on themselves exposing the anthers for 7-8 mm, glabrous to weakly puberulent along the wings; stamen slightly unequal, alternately 17.5-18 mm long; filaments distinct, ca. 4 mm long, densely short-pilose dorsally and marginally; anthers 10.5-11 mm long; thecae alternately ca. 3.5 mm and ca. 4 mm long; tubules ca. 7 mm long, dehiscing by lateral slits 1.5-2 mm long; nectariferous disc annular-pulvinate; style ca. 15 mm long, glabrous. Berry not seen.
Distribution and Ecology - Endemic to Ecuador; premontane to montane cloud forest at 1800-2468 m altitude.
