    Tropical Moist Forest and Premontane Wet Forest life zones in Ecuador, Tropical Rain Forest and Premontane Rain Forest in Colombia.
    Flowering from December to March, or possibly April; fruiting collections have been made during every month of the year except October- December and February, which suggests that the ripe infructescences may persist for a considerable length of time.
    General Description
    Coarse, sparingly branched or unbranched, root-climbing epiphyte oppressed to trunks in understory, fertile ca. 3-10 m above ground. Internodes 2.5-8.1 cm long, 1.3-3.0 cm wide, dark green to gray-green, semiglossy, with thin, fissured epidermis, obtusely sulcate on one side, drying yellowish and coarsely sulcate; roots abundant at distal nodes, to ca. 2 mm thick. LEAVES: Petiole (23.1-) 27.9-54.1 cm long, P/L=(0.48-) 0.57-0.76 (-0.93), dark green-lineate, extensively sheathed, the sheath erect to erect-spreading, the free portion prolonged by 2-3 mm; unsheathed portion of petiole 0.1-0.7 cm long, delete. Lamina (32.0-) 36.4-82.8 cm long, (8.7-) 9.1-16.8 (-20.2) cm wide, L/W=(3.06-) 4.45-5.55, IQI=(0-) 1-10, thinly coriaceous to subcoriaceous or chartaceous, semiglossy to glossy above, weakly glossy to semiglossy below, virtually concolorous or weakly bicolored, narrowly to broadly lanceolate or elliptical (usually widest near the middle), acuminate apically (the acumen 0.8-2.3 cm long), narrowly or broadly cuneate to rounded or subcordate basally; midrib prominently sunken above; primary lateral veins 13-22 or more per side, 1.1-3.1 (-4.0) cm apart, sunken above, convex below; minor veins slightly etched above, obscurely visible below; abaxial laminar surface drying ± uniformly but obscurely granular, with reticulate veins indistinct and no sign of white stitching or resin canals; adaxial surface similar. INFLORESCENCES usually solitary, occasionally paired; cataphylls rare, to at least 24.3 cm long and 2.3 cm wide, narrowly lanceolate, acutely 2-keeled; peduncle at anthesis ca. (5.6-) 6.1-13.7 cm long, P/S=ca. 0.37- 0.85, somewhat compressed, densely and finely raised-short-lineate (especially distally), suffused orange-yellow over much of its length; spathe at anthesis 16.8-22.6 cm long, 2.0-4.5 cm wide, externally pale green to orangish pink distally, dark green proximally, internally faintly pinkish to salmon-pink, persistent in fruit, becoming 16.4-22.6 cm long, 4.4-5.0 cm wide, the wall to ca. 4 mm thick toward base, becoming uniformly brilliant orange on both surfaces (slightly darker internally); spathe drying uniformly granular externally and densely but faintly short-whitish lineate on blade, internally moderately and uniformly granular, with longitudinal secretory striations to ca. 2/3 to apex; acumen of spathe to 3.4+ cm long. Stipe of spadix 0.0- 0.8 cm long; spadix ca. 12.5-18.9 cm long, the fertile male portion 1.3-1.8 cm wide, cream; sterile male zone to at least 3.0 cm long, abruptly expanded downward; female portion of spadix 3.9-5.1 cm long (5.6-8,0 cm in fruit), F/S=ca. 0.23-0.31, 1.6-2.8 cm wide (to 4.4+ cm in fruit), pale green; fertile male flowers 1.7-2.1 mm long, 0.7-1.9 mm wide, irregularly polygonal; sterile male flowers 2, 1-2.3 mm long, 1.5-2.8 mm wide, anvil-shaped; female flowers 2.9-3.5 mm long, 0..8-1.3 mm wide, the stylar canals 4 (-5). INFRUCTESCENCES: Ripe fruits sordid or ochroleucous. Seeds 0.5-0.6 mm in diameter, cochleate, finely striate with the striae minutely cancellate, drying brown and semiglossy.
