Hemiepiphytic; stem scandent, creeping, assurgent, sap soapy-scented; internodes elongate, semiglossy to matte, 4--12 cm long, 1.5--4.5 cm diam., usually slightly longer than broad, medium to dark green, conspicuously pale striate at upper edge of each node, drying brownish, often narrowly ribbed (ribs irregularly ridged, sometimes warty), epidermis weakly fissured transversely; roots moderately few, to ca. 30 cm long, drying to 2 mm diam., reddish brown; cataphylls 20--30(40) cm long, usually unribbed, sometimes 1-ribbed, sharply 1-ribbed, or weakly to sharply 2-ribbed, greenish, tinged reddish, deciduous, intact LEAVES: petioles 22--44 cm long, 4--12 mm diam., terete to broadly D-shaped, firm, dark green, sometimes purplish below, broadly sulcate, flattened or broadly convex adaxially, convex abaxially, with adaxial margins obtuse to rounded, surface semiglossy, densely and minutely white or dark striate-lineate; blades ovate to narrowly ovate or ovate-elliptic, coriaceous to subcoriaceous, conspicuously bicolorous, acuminate to narrowly acuminate at apex, rounded to truncate or subcordate at base, 21.6--51 cm long, 9--25 cm wide (1.4--2.7(3.3) times longer than wide), (0.7--1.4(2.25) times longer than petiole), usually about equal in length to petiole, upper surface dark green, semiglossy, drying dark grayish brown to yellowish brown, lower surface semiglossy to matte, paler; anterior lobe 28--45.5 cm long, 9--25 cm wide (4.9--10.2 times longer than than posterior lobes); posterior lobes 3--7 cm long, broader than long, broadly rounded to obtuse; sinus more or less V-shaped to arcuate, to 4 cm deep; midrib flat to broadly convex, paler than surface above, convex, tinged reddish or darker than surface, drying minutely granular below; basal veins 1--3(4) per side, with all free to base; primary lateral veins 8--14 per side, departing midrib at a 60--70º angle, weakly arcuate, ascending to the margins, weakly to narrowly sunken or weakly quilted, drying paler than surface, raised along the margins with the center collapsed (forming a channel) above, convex to weakly raised or weakly pleated, darker than surface, drying minutely granular, paler than surface below; interprimary veins weakly sunken or obscure above, visible below; minor veins visible, few, darker than surface, arising from both the midrib and primary lateral veins, minutely etched in upper surface of fresh leaves, drying raised. INFLORESCENCES 1--2 per axil; peduncle 3--10 cm long, 3--7(14) mm diam., pale green; spathe 12--21 cm long, (1.5--3.98(4.5--5.1) times longer than peduncle), margins reddish; spathe blade greenish white to white outside, 4 cm diam., dark maroon to cream inside; spathe tube white to greenish white, sometimes tinged pinkish or red, densely white-lineate outside, 6--9 cm long, dark maroon to violet-purple, densely white-lineate inside; spadix sessile; pale greenish to white throughout, cylindrical, tapered, 11-14(18) cm long, broadest near the base or slightly above the middle, constricted below the middle; pistillate portion green, cylindrical to ovoid-tapered, 6.6 cm long in front, 4.5 cm long in back, 1.1 cm diam. at apex, 1.3--1.4 cm diam. at middle, 8--11 mm wide at base; fertile staminate portion greenish white, tapered to clavate or cylindrical, 6.8--9.4 cm long, 9--16 mm diam. at base, 9--15 mm diam. at middle, 8--10 mm diam. ca. 1 cm from apex, broadest at or near the base, broader than the pistillate portion, sterile staminate portion not detectable; pistils 1.6--2.4 mm long, 1--1.8 mm diam.; ovary (5)6--8-locular; locules 1.2--2 mm long, 0.3--0.6 mm diam., ovule sac 0.8--1.5 mm long, with basal or sub-basal placentation; ovules (1--2)4--6 per locule, 1- or 2-seriate, 0.3--0.5 mm long, longer than or equal in length to funicle; funicle 0.1--0.4 mm long (can be pulled free to base); style 0.1--0.5 mm long, 1--1.6 mm diam., similar to style type B; style apex flat or weakly rounded; stigma discoid, brushlike, unlobed, 1--1.3 mm diam., 0.1--0.2(0.6) mm high, covering almost entire style apex or just the center of style apex; the androecium truncate, margins 4--6-sided (4--5-sided); thecae oblong, 0.3--0.5 mm wide, contiguous or more or less parallel to one another; sterile staminate flowers 4--6-sided, 1.1--1.5 mm long, 0.8--1.3 mm wide. INFRUCTESCENCE with berries orange; seeds 3--4 per locule, 1--1.1 mm long, 0.5--0.6 mm diam.
