Description:
Description: Epiphytic liana, mature branches terete, minutely striate, puberulent brown when dry; bark reddish-brown; immature branches and twigs of the new growth subterete to bluntly angled, minutely striate, puberulent, brown. Leaves linear-lanceolate to linear-elliptic, 9-14 x 1-1.5 cm, basally broadly obtuse or rounded, slightly cordate, apically long-attenuate, acute, olive-green above and reddish-brown beneath when dry, glabrous, the margins strongly revolute; 3(-5)-plinerved, the midrib deeply impressed above, raised and conspicuous beneath, the lateral nerves and the veinlets raised and conspicuous above, slightly raised but obscure beneath; petioles subterete, rugose, 2-3.5 mm long and 1-2 mm in diam., densely puberulent, dark brown. Inflorescence viscid, 12-20-flowered, the lowest nodes sterile; rachis long-tapering, bluntly angled, minutely striate, glabrous, 5-15 cm long and ca. 1-1.5 mm in diam., a few globular glands scattered along the rachis; floral bracts prominently veined, often somewhat ribbed, short-ciliate apically, oblong or oval elliptic, basally narrowed and rounded, apically rounded or acute, (13-)19-27 x, (5-)7-11 mm, pink, the margins with sessile, globular glands to 0.2 mm in diam., (3-)7-12 per side; pedicels subterete, to ca. 8 mm long and 1 mm in diam., glabrous, with a few globular glands; bracteoles oblong, oblong elliptic or oblanceolate, ca. 25 x 10 mm at anthesis, basally rounded, apically broadly rounded, glabrous or marginally short-ciliate, located ca. 1 mm below the junction of the pedicel and the calyx, completely enveloping the flowers in bud, clasping the calyx and the corolla at anthesis, with up to 15 globular marginal glands. Flowers with the calyx glabrous, 6.5-7.5 mm long; hypanthium 1.5-2 mm long and 3.5 mm in diam., cylindric, slightly rugose, basally slightly expanded, globular glands located around margins of the basal expansion and on the hypanthium; limb campanulate or erect-spreading, smooth or slightly ribbed, 5-6 mm long; lobes triangular, the margins conspicuously glandular callose-thickened, the thickenings nearly contiguous at the apex of the lobe; sinuses obtuse or rounded; corolla ca. 32 mm long and 6 mm in diam., pink, densely short-pilose in the distal 1/3, the lobes triangular, ca. 2 mm long; stamens 27-28 mm long; filaments short-pilose in the distal 1/2, alternately 4-4.5 mm and 7.5-8 mm long; anthers including the tubules alternately ca. 24-24.5 mm and 20 mm long; thecae 6-7 mm long; style 31-33 mm long. Berry not seen.
Distribution: Endemic to Panama and known only from six collections in the Bocas del Toro/Chiriquí Prov. border area and N of Santa Fé (Veraguas Prov.), in cloud forest and tropical wet forest, at elevations of 300-770 m.
Conservation Status: Rare and endangered.
Illustration: Luteyn (1983), fig. 61A-C.
Type: Panama. Bocas del Toro: Chiriquí Trail, between Criollo and Quebrada Higuerón, Kirkbride & Duke 779 (holotype: NY; photo of type DUKE, NY; isotype: MO).
