Epiphytic and terrestrial shrubs, 1.5-3 m tall; stem base ca. 2.5-5 cm in diam-eter; mature branches and twigs of new growth bluntly angled to terete, often glaucous, glabrous to densely pilose, often glabrescent, the trichomes tan to yellowish and 0.5-2 mm long, bark brown to reddish brown. Leaves ovate, lan-ceolate, elliptic, oblong, rarely obovate, (5-) 7-26 (-32) cm long, (1-) 2-10 (-13) cm wide, basally obtuse, rounded or truncate, often slightly cordate apically acute to long acuminate sometimes abruptly short acuminate, tan, olive brown, or reddish brown when dry, glabrous to moderately short pubescent on the lam-ina above, glabrate to densely pubescent beneath especially along the nerves; (3-)5(-9)-plinerved with the midrib and the lateral nerves shallowly to deeply impressed above, raised and conspicuous beneath, the veinlets usually slightly elevated on both the surfaces but secondary lateral nerves and veinlets often deeply impressed above giving the lamina a strikingly bullate appearance; peti-oles subterete, rugose, (4-) 6-16 (-22) mm long, (1-) 2-3 (-5) mm in diameter, glabrous to densely pilose with trichomes to 1.5 mm long. Inflorescence viscid, 20-35(-52) flowered, encircled at the base by bracts, rachis bluntly angled, longi-tudinally ribbed, glabrous or infrequently densely sericeous, 4-12(-20) cm long, 4-6(-10) mm in diameter, rose colored but drying yellowish to orangish brown, rarely with minute, reddish, clavate glands especially at the base of the floral bracts; floral bracts pink, smooth or muricate, glabrous, oblong, obovate or oblan-ceolate, basally narrowed and truncate, apically rounded to acute, the tips rarely reflexed, (1.5-)2-5(-6) cm long, 1-2.5(-3.5) cm broad; pedicels smooth or rugose, usually longitudinally ribbed, usually swollen at both ends, glabrous or infre-quently densely sericeous, 6-15(-20) mm long, 0.5-1.5(-2) mm in diameter, rarely with sessile, reddish glands or cartilaginous teeth at the apex; bracteoles glabrous, infrequently conspicuously nerved, ovate lanceolate, basally somewhat auriculate clasping, 1-5(-7) mm long, 1-2(-3.5) mm wide, apically glandular callose thick-ened, rarely callose thickened for nearly the entire length. Flowers with the calyx glabrous or infrequently densely pilose, 5-9(-11) mm long, viscid, the tube cylindric, coarsely ribbed, rugose, often muricate, (1.5-) 2-4 (-5.5) mm long, strongly expanded basally, pinkish green, at anthesis becoming green, the limb cylindric or spreading, often striate, 3.5-6(-8) mm long including the lobes, dark rose at anthesis becoming pale rose to pink, the lobes triangular, 1-2.5 (-4) mm long, 2-3 mm broad, erect after anthesis, usually completely glandular callose thickened, green to brownish green when fresh, the sinus obtuse to broadly acute; corolla narrowed to the throat, viscid, 1.5-3.5(-4) cm long, 4-8 mm in diameter, densely sericeous or rarely glabrous externally, moderately pilose or rarely glabrous within with translucent trichomes 0.5-1 mm long, the tube white or with a pinkish hue basally, the lobes triangular, 1-3 mm long, 2-3 mm wide, reflexed at anthesis, white with purple margins; stamens (13-)20-34 mm long, the filaments alternately (1.5-)3.5-4.5(-6) mm and (4.5-)8-12 mm long, short pilose distally, white to pink, the anthers including the tubules alternately (8.5-)15-26 mm and (11-)27-32 mm long, the tubules purplish orange, the thecae 5-20 mm long, orange; style (17-)20-35(-40) mm long, green. Mature berry not seen.
