Description:
Description: Epiphytic shrub; stem glabrate; twigs densely short white pilose or glabrate; vegetative bracts persistent for at least one season, surrounding the branches. Leaves bullate, lanceolate, elliptic-lanceolate to oblong-elliptic, (10.5-)15-24.5 x (3-)4-9 cm, base obtuse or rounded, apex short-acuminate, margin slightly revolute, moderately short-pilose above, densely pilose beneath with hairs ca. 0.8 m long; 5(-7)-plinerved with inner pair of lateral nerves arising 1.5-2.5 cm above base, midrib thickened and raised through proximal 1.5-2.5 cm otherwise strongly impressed above, lateral nerves strongly impressed above, reticulate veinlets slightly impressed or raised above, all veins raised beneath; petiole 5-15 mm long, densely short-pilose. Inflorescence 12-24-flowered, surrounded at base by numerous subcoriaceous, ovate to obovate bracts, the outermost densely appressed pilose, the inner pilose only at distal tips; rachis subterete, bluntly angled, congested, glabrous, 3 cm long, sometimes with flattened glandular fimbriae at base; floral bracts subcoriaceous, erect, appressed to and concealing calyx at anthesis, muricate, oblong-obovate, rarely suborbicular, 15-21 mm x 12-15 mm, glabrous but sometimes ciliate towards apex and sometimes with inconspicuous glandular fimbriae on dorsal surface, pink to red; pedicel 1.5-3.5 mm long, glabrous or weakly short-pilose, glandular-fimbriate; bracteoles basal, clasping calyx at anthesis, oblanceolate, oblong, 10-13(-16) x 3-5(-6.5) mm, margin glandular-fimbriate, sometimes ciliate, lamina sometimes with scattered glandular fimbriae. Flowers with calyx 13-16 mm long; hypanthium cylindric or barrel-shaped, 10-ribbed, 3-4 mm long, base nonapophysate, densely pilose with white hairs 0.4-0.7 mm long, with scattered glandular fimbriae; limb erect, 10.5-12 mm long; lobes erect or slightly spreading, oblong, basally imbricate, 9-10 mm long, erect after anthesis but curling around style base, ciliate, glandular-fimbriate; corolla more or less chartaceous the proximal half and leathery the distal half, 16-17 mm long, cylindric but narrowing to throat where it is slightly and obtusely angled opposite the lobes, on these angles weakly pilose otherwise glabrous, pink, the lobes spreading at anthesis, ca. 1.5-2 mm long; stamen ca. 15 mm long; filaments alternately ca. 4 mm and 7 mm long, glabrous lower half but short-pilose upper half; anthers alternately ca. 12 mm and 10 mm long; thecae 4-5 mm long; tubules 6-8 mm long; style ca. 17 mm long. Berry 10-12 mm diam., pilose, capped by persistent calyx lobes, lavender.
Distribution: Endemic to Ecuador; wet montane forest edge at 900-1600(-3325 ?) m altitude.
Type: Ecuador. Morona-Santiago: Cordillera de Cutucú, on banks of Río Itzintza, 1067 m, 17 Nov-5 Dec 1944 (fl), Camp E-1201 (holotype: US, photo NY neg. 9156; isotype: NY).
Conservation Status: Rare and endangered.
