Description:
Description: Hemiepiphyte (fide label data); stems subterete becoming terete at maturity, smooth, glabrous, drying reddish-brown. Leaves elliptic, obovate, (3.5-)5-13 x (2-)3-8 cm, basally broadly cuneate and short attentuate, apically rounded, glabrous; pinnately veined with the 4-7 lateral nerves anastomosing near the margin, midrib impressed proximally becoming raised distally above and prominently raised beneath, lateral nerves and veinlets slightly raised on both surfaces; petiole subterete, slightly rugose, glabrous, 5-7 mm long and 3-4.5 mm diam. Inflorescence axillary, subfasciculate, 5-6 flowered, spherical in outline; inflorescence bracts oval-elliptic or ovate, short-pilose, 6-7.5 mm x 5 mm; floral bracts strongly keeled, short-pilose, marginally glandular-fimbriate and ciliate, obovate, 7-9 x 5.5 mm; pedicels coarsely angled, glabrous, 1-2 mm long and 1 mm diam.; bracteoles strongly keeled, short-pilose, marginally glandular-fimbriate and ciliate, obovate to spathulate, apically rounded and mucronate, (7-)9-10 x 5.5-7 mm, completely enveloping the perianth in bud, tightly clasping the calyx and corolla at anthesis. Flowers with calyx 5-5.5 mm long; hypanthium cylindric, smooth but slightly ribbed or angled, glabrous, 2-2.5 mm long; limb including lobes erect-spreading, smooth, 3 mm long; lobes triangular, acute, short-pilose, 1-1.5 mm long and broad; sinuses rounded at anthesis; corolla cylindric, glabrous, yellow (fide label data), 8-8.5(-10) mm long and 3 mm diam., the lobes oblong, obtuse, 1 mm long; stamens equal, 7 mm long; filaments glabrous, 3-3.5 mm long, connate into a tube 2.5 mm long; anthers including tubules 6 mm long; thecae 3 mm long, slightly granular, basally with an appendage ca. 0.5 mm long. Berry not seen.
Distribution: Endemic to Peru.
Type: Peru. Hánuco: Rocky slope above the Río Huallaga at Tingo María, 4 Oct 1972, Croat 21089 (holotype, NY; isotypes, MO + 4 others).
Conservation status: Rare and probably endangered.
