Epiphytic shrub, vegetatively glabrous. Mature stem terete to subterete, striate; bark reddish-brown when dry; twigs subterete, complanate to bluntly angled, striate, reddish-brown when dry; bud scales 2, broadly ovate, mucronate, ca. 3 mm long. Leaves thick coriaceous, imbricate, subsessile, flat to apparently involute (especially when young), clasping the stem, ovate to ovate-elliptic, 3.2-6 x 2-3.5 cm; base rounded and deeply cordate; apex shortly and bluntly acuminate; margin weakly and remotely crenate, slightly revolute; 7-9-plinerved from near or just above the base, midrib and lateral veins plane to slightly raised on both surfaces, reticulate veinlets raised on both surfaces but inconspicuous beneath; petiole subterete, broadly canaliculate above, 2-5 x 2-2.2 mm. Inflorescence with flowers solitary and somewhat concealed by the involute leaves, surrounded at the base by the 2 persistent bud scales plus several tiny, ovate, obtuse bracts less than 1 mm long; floral bract ovate, acute, ca. 2 mm long, the margin glandular-fimbriate; pedicel subterete, broadening distally, 1.5-2 x 1.5 mm, bearing numerous glandular fimbriae at articulation with calyx; bracteoles located near base, striate, nearly concealing calyx, elliptic to ± oblanceolate, apically rounded, 7-8 mm long. Flowers 5-merous; hypanthium cylindric-campanulate, apparently bluntly angled opposite the sinuses, 3-3.5 x 2.5-3 mm; calyx glabrous, 6-7 mm long, the limb campanulate, ± striate, ca. 5 mm long including the lobes, ca. 7 mm in diam. at the distal tip; lobes triangular, acute, conspicuous, 2-2.5 x ca. 2.8 mm; sinuses obtuse to narrowly rounded; corolla succulent, bistratose, coriaceous when dry, ca. 7 mm long but still in bud, glabrous without but moderately short-pilose on lobes within, "buds green"; stamens 10, immature; filaments glabrous, ca. 1.2 mm broad at base but immature; anthers ca. 6 mm long; thecae ca. 5 mm long; tubules ca. 1 mm long; style glabrous.
