Epiphytic shrub;  stem terete, striate, glabrous;  twigs subterete, bluntly angled, striate, densely white puberulent, glabrate.  Leaves coriaceous, ovate to ovate-elliptic, 3.5-5.6 x 1.2-1.8 cm, base rounded to broadly obtuse, apex long-acuminate, margin entire and slightly revolute, glabrous on both surfaces, lacking glandular fimbriae;  3(-5)-plinerved, midrib weakly impressed in the proximal 1/2-3/4 becoming plane to slightly raised in the distal 1/2-1/4 above, lateral nerves and reticulate veinlets slightly raised above, all nerves slightly raised beneath;  petiole subterete, strongly canaliculate above, 4-6 mm long, densely puberulent, glabrate.  Inflorescence axillary, solitary, racemose, 6-9-flowered, surrounded at the base by a series of broadly ovate bracts to 2 mm long;  rachis subterete, sharply angled, 1.5-2.5 cm long, glabrous, eglandular;  lowest 3-4 floral bracts sterile (without flowers), the more distal fertile ones conduplicate or concave, oblong-obovate, rounded, 7-16 x 4-7 mm, glabrous, eglandular, surrounded the buds and then spreading and becoming strongly reflexed through and post-anthesis;  pedicel subterete, striate, 7-10 mm long, glabrous;  bracteoles basal, oblong, rounded, 1.5-2 mm long, glabrous, but marginally conspicuously glandular-fimbriate in the distal 1/3.  Flowers with calyx 4-5 mm long, glabrous;  hypanthium cylindric, broadly and bluntly ribbed, 1.5-2 mm long, the base shallowly but distinctly apophysate;  limb erect-spreading to cylindric-campanulate, 2.5-3 mm long;  lobes ovate, ca. 1 mm long, erect after anthesis, the margin lacerate-glandular, dark in color and apparently thinner than lamina proper;  sinuses acute;  corolla cylindrical, slightly narrowing at the throat, 14-16.5 mm long and ca. 5 mm diam, the lobes slightly spreading, ovate, apiculate, ca. 1 mm long;  stamens of overall equal length, ca. 13.5 mm long;  filaments distinct, alternately ca. 4.5 mm and 2 mm long, glabrous;  anthers alternately ca. 10.7 mm and 12.3 mm long;  thecae alternately ca. 4.7 mm and 3 mm long;  tubules alternately ca. 6 mm and 9.5 mm long, dehiscing by clefts about half the tubule length;  style equalling the corolla, glabrous.  Berry not seen.

    Distribution.  Endemic to Costa Rica (Limón Prov.) and known only from the type locality and one other collection, at 500-700 m.  Rare and probably endangered.
