Description:

Description: Epiphytic shrub; branches subterete or bluntly angled, slightly striate, glabrous, with scattered pustular glands to 0.3 mm diam., reddish-brown. Leaves lanceolate or elliptic, (5-)7-14.5 x 2-5.5 cm, basally obtuse or narrowly rounded, apically acuminate (sometimes abruptly short caudate-acuminate), glabrous but with scattered black sessile and pustular glands 0.1 mm in diam. along upper leaf surface, the sessile ones often caducous leaving a reddish punctate scar; 5(-7)-plinerved, innermost lateral nerves arising to 1.5 cm above base, midrib and lateral nerves deeply impressed above and conspicuously raised beneath causing leaves to be bullate, veinlets slightly impressed above and raised beneath; petioles subterete, rugose, 3-5 mm long and 2.5-3.5 mm in diam., glabrous or hispid only on abaxial surface, provided with globular glands 0.2 mm in diam. in distal portion. Inflorescence viscid, ca. 20-flowered but lowest few nodes sterile; rachis subterete, bluntly angled, striate, glabrous, 11-14 cm long (upper portion still in bud) and 3-4 mm in diam. with scattered globular or angular glands ca. 0.2 mm long; floral bracts ovate, oblong or oval-elliptic, 21-25 x 10-12 mm, glabrous or weakly ciliate, basally narrowed, truncate and clasping, apically rounded, marginally crisped and with 12-20 dark red globular glands 0.1-0.2 mm in diam. on each side, pink; pedicels subterete, swollen distally, striate, glabrous, 5-7 mm long and 0.75 mm in diam., with globular glands concentrated at distal swollen portion; bracteoles oblong-oblanceolate, 10-14 x 6-8 mm, located midway along pedicel and clasping or nearly concealing entire calyx and lower 1/5 of corolla at anthesis, margins crisped and with dark red globular glands scattered along edge. Flowers: calyx glabrous, ca. 3.5-5 mm long; hypanthium cylindric, obscurely ribbed, 1.5-2 mm long, truncate basally, covered by globular or angular glands 0.2 mm in diam.; limb spreading-campanulate, 2-3 mm long and covered by globular glands; lobes broadly triangular, 1 mm long, erect after anthesis, completely glandular-callose distal 2/3 and covered by globular glands; sinuses flat to broadly rounded; corolla slightly narrowed distally, glabrous without but sparsely pilose within, ca. 19 mm long and 4 mm in diam., pink when fresh, lobes triangular, acute or obtuse, 1 mm long; stamens 17 mm long; filaments alternately ca. 2.5 mm and 6 mm long, the short ones sparsely pilose dorsally at distal tips, the long ones densely pilose ventrally in distal half; anthers alternately ca. 16.5 mm and 13 mm long; thecae ca. 7 mm long; style ca. 19 mm long. Berry not seen.

Distribution: Endemic to W Panama and only found in the Fortuna Dam area (Chiriquí Prov.), in cloud forest, at ca. 1100-1800 m. Locally common, but rare overall.
