Hemiepiphytic; stem appressed-climbing, scandent, often pendent, green becoming brownish to gray-green; internodes glossy, to 25 cm long, (0.8)1--2 cm diam., longer than broad, gray-green, semiglossy, more or less terete, epidermis drying light yellow-brown, conspicuously fissured or ridged but smooth, frequently flaking free; roots thin, more or less twisting or sinuous, few per node; cataphylls 10--29 cm long, unribbed to obtusely 1-ribbed or bluntly to sharply 2-ribbed, cream to medium green, magenta speckled, quickly deciduous, fragile. LEAVES: petioles 9--24 cm long, 8--10 mm diam., more or less terete, somewhat spongy, somewhat flattened adaxially, surface semiglossy to glossy, frequently fissured, medium green, sometimes maroon-spotted; blades narrowly ovate-cordate, subcoriaceous, concolorous or weakly bicolorous, acuminate to long-acuminate at apex (the acumen inrolled), cordate at base, 12--23(27) cm long, 7.4--19 cm wide (1.3--1.8 times longer than wide), (0.8--2.2 times longer than petiole), broadest just below point of petiole attachment, upper surface drying yellow-green, semiglossy, lower surface glossy; anterior lobe 10--21 cm long, 7.4--19 cm wide (2.5--4.2 times longer than posterior lobes); posterior lobes (2.8)3.6--7(8.2) cm long, (3.1)4.3--7.7 cm wide; sinus hippocrepiform; midrib convex to broadly convex and slightly paler above, convex to broadly convex and paler below; basal veins ca. 3 per side, with 0--1 free to base, 2--3 coalesced to 5 mm long, flattened to raised; posterior rib 0.5--1 cm long, never naked; primary lateral veins about 3(4) per side, departing midrib at a 55--65º angle, more or less straight to the margins, convex to weakly raised above, convex below; interprimary veins drying darker than surface below; tertiary veins more or less obscure to visible and darker than surface below; minor veins fine below, arising from both the midrib and primary lateral veins; "cross-veins" conspicuous (in Central America). INFLORESCENCES erect, 1 per axil; peduncle (3.5)5--7(11.5) cm long, 5--7 mm diam., subterete, purplish tinged, whitish streaked; spathe 11--15 cm long, (1.2--3(4.3--4.7) times longer than peduncle), constricted only slightly midway above the tube; spathe blade green to greenish white, with reddish speckling outside, 7--7.5 cm long, pale greenish cream inside; spathe tube violet-purple, short lineate outside, 6.7--7 cm long, dark violet-purple inside; spadix sessile; ca. 13 cm long; pistillate portion white to pale greenish white, 4.5--5 cm long, 1.5 cm diam. throughout; staminate portion 8.5--9.2 cm long; fertile staminate portion white, drying redding brown, 1.2 cm diam. throughout; sterile staminate portion 1.5 cm diam.; pistils 7.5 mm long, 1.6 mm diam.; ovary 4--5-locular, 6.2 mm long, 1.6 mm diam., with axile placentation; locules ca. 6.2 mm long; ovules 15--25 per locule, 0.2--0.25 mm long, 2--3-seriate, style similar to style type D; style apex with low style boss. INFRUCTESCENCE with pistillate spadix 6.5--7.5 cm long, 2.5--3.5 cm wide; berries 5.9 cm long, 2.5 cm diam.; seeds 24--25 per locule, yellow-orange, 1.2 mm long, 0.5 mm diam., thin and faintly striate.
