PlaceOfPublication J. Wash. Acad. Sci. 18(6): 164. 1928.
Note TYPE: Costa Rica, Maxon & Harvey 8045 (US, holotype).
Description Epiphytic shrubs, the branchlets terete, finally compressed, black when dry and covered with gray spots, glabrous. Leaves persisting toward the apex of the branchlets, obovatp or obovate rotund, 1.5-4.5 cm long, 1.0-2.2 cm wide, round or truncate at the apex, cuneate basally, the costa scarcely distinguishable, the lateral veins not visible, thickly coriaceous, concolorous, glabrous, the margin slenderly callose; petioles thick, to 1 cm long, to 0.3 cm wide; stipules deciduous, persistent toward the apex, obovate rotund, to 1.5 cm long, rounded, coriaceous, glabrous, the veins conspicuous or evanescent. Flowers terminal, solitary, to 4 cm long, enclosed partially by 2 large bracteoles, these compressed rotund, to 2 cm long, scarious, glabrous, venose; hypanthium rectangular, to 1.8 mm long, glabrous, the calycine cup none, the lobes obviously absent; corolla white, the tube infundibuliform, 2-3 cm long, ca. 0.3 cm wide, rigid, glabrous, the lobes 4, compressed rotund, to 1 cm long, wider than long, glabrous; stamens subsessile, the anthers linear oblong, ca. 3 mm long, affixed near the mouth; style ca. 6 mm long, the stigmas 2, subulate, ca. 3 mm long. Fruits not seen.
Habit Epiphytic shrubs
Distribution known only from Costa Rica and Panama.
Note The leaves are strikingly ligulate. As few flowers are available for dissection I elected to dissect one whose corolla measured only 2 cm in length. No ovules were located; this coupfed with the absence of fruit in the two known collections is cause for spec- ulating that the flowers are unisexual. In this dissection the style and stigmas measured only about 1/2 the length of the corolla tube.
Specimen VERAGUAS: NW of Santa Fe, 1 km from Escuela Agricola Alto de Piedras, Mori & Kallunki 4873 (MO).
