General Description

Much-branched vines clambering atop shrubs or understory trees or densely covering trunks of larger trees to at least 10 m (rarely sprawling over rocks) fertile ca. 1-6 m above ground the flowering branches looping-divergent or pendent, curving upward distally with the inflorescences held erect. Internodes 0.1-5.3 (-14.3) cm long, 0.4-1.1 cm wide, dark green, gray-green, grayish brown, purplish gray or purplish brown, matte (especially in age) to glossy, narrowly flattened to sulcate on one side becoming very condensed drying yellow-green to mid-brown or dark brown moderately to coarsely sulcate; roots rare and (when present) few at distal nodes, to ca. 1.0 mm in diameter. LEAVES: Petiole 5.0-17.1 cm long, P/L= (0.38-) 0.44-0.99 (-1.05), weakly glossy to glossy, often with dark green lineations, extensively sheathed the sheath horizontally spreading (may be erect distally), ± revolute proximally (at least on one side) the free portion somewhat asymmetrically prolonged by 0.0-1.8 cm; unsheathed portion of petiole obsolete or to ca. 0.7 (-0.9) cm long, D-shaped, convex below, broadly sulcate or flattened above with the margins rounded to obtuse or acutish. Lamina (7.9-) 11.0-19.8 (-23.5+) cm long, (2.4-) 3.7-12.5 (-14.8) cm wide, L/W= (1.22-) 1.45-3.21 (-3.47), IQI= (0-) 2-8 (-11) membranous to thinly coriaceous or subcoriaceous, matte or weakly velvety to glossy above, matte to semiglossy or glossy below, concolorous to moderately bicolored, narrowly to broadly elliptical to narrowly ovate-lanceolate, ovate deltate-ovate, oblanceolate oblong, suborbicular or (very rarely) obovate or rhombic (widest below to near or slightly above the middle), gradually to rather abruptly short- to moderately long-acuminate (rarely merely acute) apically [the acumen ca. 0.4-1.9 (-2.3) cm long, sometimes with an arista to ca. 0.45 cm long], narrowly or broadly cuneate to rounded subtruncate or subcordate (the sinus to ca. 0.2 cm deep) basally; midrib weakly sunken to sunken above convex and often slightly paler below; primary lateral veins 5-11 per side 0.3-3.4 cm apart, weakly sunken above, convex below, the interprimaries obscure; minor veins obscurely to moderately visible and darker below; abaxial laminar surface drying virtually smooth to uniformly and very densely granular, with the reticulate veins scarcely visible to evident (especially distally); white stitching not visible to scattered along the resin canals; resin canals obscurely to moderately visible, usually flanking the lateral veins at a distance; adaxial surface virtually smooth to moderately or densely and uniformly granular (the granules occasionally more concentrated along the midrib and major veins), the reticulate veins usually obscure except toward the margins (occasionally evident throughout); white stitching absent to scattered or abundant, often parallel to the lateral veins; resin canals not or scarcely visible. INFLORESCENCES solitary; cataphylls absent; peduncle (0.2-) 0.5-1.7 (-2.0) cm long, P/S=(0.03-) 0.05-0.14 (-0.19), subterete, "lenticellate"-roughened (at least occasionally), mostly hidden in petiole sheaths of subtending leaves; spathe at anthesis (7.1-) 8.4-17.5 cm long, 1.7-3.6 (-4.2) cm wide, externally semiglossy to glossy, light yellow-green to green at base, greenish white to cream-white distally and toward margins, internally uniformly cream-colored or yellowish white to pale green (especially toward fruit); spathe drying uniformly and moderately to densely granular externally, with resin canals obscurely to moderately visible, internally virtually smooth to uniformly and moderately to densely granular with longitudinal secretory striations in basal 1/2 - 2/3 or nearly to apex; acumen of spathe (0.3-) 0.7-3.0 cm long. Stipe of spadix 0.2-1.2 cm long; spadix (6.4-) 6.7-13.3 cm long, the fertile male portion 0.7-1.2 (-1.5) cm wide, white to cream-white; apical sterile male zone not evident, or to ca. l.1 cm long; intermediate sterile male zone 0.3-0.9 (-1.5) cm long; fertile female portion of spadix (1.8-) 2.1-4.9 cm long [to 6.7 (-7.5?)] cm in fruit), F/S=(0.25-) 0.27-0.38 (-0.42), (0.6-) 0.7-1.4 (-1.6) cm wide (to 3.9+ cm in fruit), pale green to greenish yellow; fertile male flowers 1.1-2.4 (-3.1) mm long, 0.6-1.8 (-2.9) mm wide, irregularly polygonal, columnar to ± compressed-cylindrical; apical sterile male flowers (when present) 1.8-2.0 mm long, 0.7-2.2+ mm wide, ± clavate or obturbinate; intermediate sterile male flowers 1.6-2.7 (-2.9) mm long, (0.5-) 1.1-2.6 (-3.0) mm wide, ± anvil-shaped to obconical, drying darker and appearing oil-rich or waxy distally; female flowers 1.5-3.2 mm long, 0.7-2.0 mm wide, the stylar canals (3-) 4-5 (-6). INFRUCTESCENCES: Ripe fruits greenish white to white, translucent. Seeds 0.7-1.0 mm long, 0.20-0.35 mm wide, reddish or purplish, ± straight to slightly sigmoid or curved, finely striate with striae not appearing cancellate, drying dark brown and glossy.


It ranges from extreme southeastern Chiapas to west-central Panama.
