Description:
Description: Epiphytic shrub 7-10 dm tall, arising from a lignotuber. Mature stems subterete, smooth or minutely striate, glabrous or puberulent; bark blackish-red when dry; immature stems and twigs of the new growth subterete, striate, glabrous or puberulent, brownish or grayish when dry; bud scales 4 (?), narrowly ovate to linear, long-acuminate, 2.5-5 mm long. Leaves thin-coriaceous, lance-elliptic to ovate, (4.5-)6-16 x (1.5-)2-5.4 cm; base rounded to obtuse or shortly cuneate; apex short- to long-acuminate; margin remotely crenate, glabrous, glandular-fimbriate beneath but fimbriae soon deciduous; 5(-7)-plinerved, midrib impressed above, thickened and raised for the proximal 1-1.5 cm, elevated beneath, lateral veins and reticulate veinlets slightly raised on both surfaces; petioles subterete, rugose, glabrous, slightly winged laterally, 5-10 x 1.5-2 mm. Inflorescence racemose with a solitary flower, the pedicel long-pendent, arising from a short rachis 1.5-3.5 mm long; floral bract ovate, ca. 1 mm long, the margin glandular-fimbriate; pedicels terete, minutely ribbed, 150-200 x 0.3-0.8 mm, but greatly expanded distally near articulation up to 8 mm in diam., glabrous; bracteoles nearly basal, aristate, 1.5-4 mm long, the margin glandular-fimbriate. Flowers 5-6-merous; hypanthium obconic, muricate, 3.5-5 mm long; calyx 9-12 mm long, glabrous, the limb campanulate, conspicuously veined, 5-7 mm long including the lobes, ca. 13 mm in diam. at the distal tip; lobes broadly ovate, apiculate, 2.5 x 5 mm; sinuses acute to obtuse; corolla thin, chartaceous when dry, campanulate-cylindric, pink to greenish-white, ca. 22 x ca. 25 mm, glabrous, the lobes broadly ovate, 2.5 x 6 mm, glabrous within; stamens 10 or 12, equal, ca. 12 mm long; filaments distinct, ca. 4.5 mm long, 2 mm wide at base, ciliate; anthers including the tubules ca. 10 mm long; thecae 6.8-7.5 mm long; tubules 3.0-3.2 mm long, pilose adaxially, dehiscing by oval clefts 1.5-2 mm long; style glabrous, 16-18 mm long. Berry not seen, but reportedly pure white when mature.
Distribution: Known from Limón Prov., Costa Rica and thence disjunct to west-central Panama in the provinces of Veraguas and Coclé at elevations from 600 to 1100 m.
Type: Panama. Veraguas: Vic. of third branch of Río Santa María, 10-14 km NW of Santa Fé, 650-750 m, 10-11 Oct 1975 (fl), Dressler 5170 (holotype: DUKE, photo NY s.n.).
Conservation Status: Rare and probably endangered.
