Description:
Description: Terrestrial or epiphytic shrub with branches to 2 m tall; stem glabrous; twigs complanate, cinereous. Leaves subcoriaceous, elliptic, oblong-elliptic or ovate-elliptic, 6-16 x 2.5-6 cm, base rounded, apex abruptly caudate-acuminate with acumen to 3 cm long, glandular-fimbriate and short-pilose (especially along nerves) on both surfaces; 5-7(-9)-plinerved from base, midrib and lateral nerves slightly impressed above and conspicuously raised beneath, reticulate veinlets inconspicuous but raised on both surfaces; petiole 5-8 mm long, short-pilose or hispid. Inflorescence 15-flowered, the flowers restricted to distal 1/5 of inflorescence; rachis 5-7 cm long, densely short-pilose with white hairs 0.2-0.3 mm long; floral bracts: those of proximal 3/5 of inflorescence caducous causing it to appear pedunculate, those of next distal 1/5 usually and usually emarginate, densely short-pilose on both surfaces, grass-green becoming pink at base and red distally; pedicel ca. 0.5 mm long, densely short-pilose; bracteoles lacking. Flowers with calyx ca. 9-9.5 mm long, densely short-pilose; hypanthium cylindric to obconic, 2.5-3 mm long, basally truncate and with a fringe of glandular fimbriae; limb cylindric or slightly spreading, weakly striate, 6-6.5 mm long; lobes triangular, acute, ca. 2.5 mm long, marginally glandular-fimbriate, cream-colored; sinuses rounded; corolla cylindric, 30-35 mm long, short-pilose in distal 3/4, nearly glabrous in proximal 1/4, inconspicuously glandular-fimbriate, the lobes triangular, ca. 1 mm long; stamen alternately ca. 13.8 mm and 15.6 mm long; filaments distinct (lightly coherent prior to anthesis), alternately ca. 3 mm and 5.6 mm long, glabrous; anthers alternately ca. 11.5 mm and 10.4 mm long; thecae slightly granular, ca. 4 mm long; tubules dehiscing by clefts ca. 2.5 mm long; style 30-36 mm long. Berry not seen.
Distribution: Colombia and Ecuador; in wet forest at 250-1250 m altitude. Rare and endangered.
Type: Colombia. Nariño: Altaquer-Junín road, 13-15 km W of Altaquer, 1250 m, 26 Feb 1979 (fl), Luteyn & Lebrón-Luteyn 6867 (holotype: COL; isotypes: AAU, E, MO, NY, U, US). Image: Line-drawing.
