    General Description
    Terrestrial, rarely epiphytic; stem to 50 cm long, 1-3 cm diam.; roots dense, drying whitish to tan, moderately elongate; cataphylls thin, lanceolate, 6-13 cm long, acuminate at apex, drying reddish brown, persisting semi-intact, quickly weathering to straw-colored fibers. LEAVES erect-spreading; petioles 11-31 cm long, 4-8 mm diam., subterete to triangular, flattened to broadly convex adaxially, sometimes with the margins sharp, rounded or sharply 1-ribbed abaxially; geniculum slightly paler and scarcely thicker than petiole, (0.6)l-3 cm long; sheath 1.5-3 cm long; blades coriaceous to subcoriaceous, broadly elliptic, rarely somewhat oblanceolate, shortly acuminate at apex, acute to narrowly acute at base, 35-61 cm long, 10-19 cm wide, broadest near the middle, the margins flat to slightly revolute; upper surface weakly glossy to semiglossy to glossy, dark to medium green, lower surface semiglossy, conspicuously paler; midrib convexly raised at base, becoming sharply acute toward the apex above, slightly paler than surface, acutely raised below; primary lateral veins 24-43 per side, departing midrib at 40-60° angle, straight to the collective vein, usually prominently and sharply raised above, flat to sunken below; interprimary veins almost as conspicuous as primary lateral veins; tertiary veins obscure, prominulous above and below on drying; reticulate veins not visible; collective vein arising from the base, equally as prominent as primary lateral veins, 10-15 mm from margin. INFLORESCENCES erect; peduncle 21-52 cm long, 3-4 mm diam., 1-2.2 x as long as petiole, green to purple, terete, sometimes with many weakly to prominently raised striations; spathe reflexed or rarely spreading, subcoriaceous, green, usually tinged with purple, oblong-lanceolate, 3.5-7 cm long, 0.6-1.3 cm wide, broadest near the base, acute to abruptly acuminate at apex, acute at base; spadix green, usually tinged with purple to purplish brown, sessile or stipitate to 2 mm, scarcely tapered, erect, 2.5-5.5 cm long, 3-5 mm diam. midway, 3-4 mm diam. near apex; flowers square to rhombic, 1.4-2 mm long, 1.4-1.8 mm wide, the sides straight; 5-9 flowers visible in principal spiral, 4-6 in alternate spiral; tepals matte, minutely papillate; lateral tepals 1.1-1.2 mm wide, the inner margins rounded, the outer margins 2-sided; pistils emergent, glossy; stamens exserted; anthers pink-orange, 0.4-0.5 mm long, 0.5 mm wide; thecae oblong-ellipsoid, slightly divaricate; pollen pale orange fading to white. INFRUCTESCENCE erect; spathe persisting; spadix 8-10 cm long, 1.3-1.7 cm diam., with berries scattered throughout; berries (immature) green, emergent ca. halfway, obovoid, shortly beaked at apex on drying, ca. 6.5 mm long, ca. 4 mm diam.; pericarp with raphide cells; seeds 2 per berry, oblong-obovoid, flattened, beaked at apex, 4-4.5 mm long, 2.5-2.7 mm wide, 1.5-1.8 mm thick, with a gelatinous appendage at one end.
    Ranges from the Amazon slopes of Ecuador to northern Peru on both slopes of the Cordillera Oriental and the Cordillera Central.
    This species is ecologically variable. In Ecuador it is known from premontane moist, premontane wet, lower montane moist, and lower montane wet forest life zones, while in Peru it is known from premontane rain and montane rain forest life zones.
