Description:
Description: Epiphytic shrub; branches terete, striate, fissured, grayish, glabrous. Leaves coriaceous, broadly elliptic, 1.8-5.1 x 1.2-2.8 cm, basally rounded to obtusely cuneate, apically entire, glabrous but inconspicuously glandular strigillose on both surfaces, more so beneath; obscurely 3-plinerved; petioles glabrous, 2-3 mm long. Inflorescence of solitary or paired flowers in the leaf axils; pedicels pendent, arching in both young and older fruit, 6-8 mm long, with dense bulbous based trichomes at least distally; floral bract triangular, appressed, ca. 0.6 mm long; bracteoles triangular, alternate, 0.3-0.5 mm long, nearly basal. Flowers 5-merous; calyx glabrous; hypanthium 2-2.2 mm diam., densely tuberculate with bulbous-based, glandular protuberances, ca. 2.5 mm high; limb glabrous, erect to slightly spreading, 0.5-0.7 mm long; lobes erect, triangular, glabrous, 0.4-0.5 mm long. Fruit a globose, densely tuberculate white berry; seeds cuneiform with a striate, transparent (when dry) outer layer exhibiting the green embryo within.
Distribution: Endemic to Panama and known only from the type.
Type: Panama. Veraguas: 2 km N of Cerro Tute, Witherspoon 8830 (holotype: MO).
