    General Description
    Epiphyte; stems short, densely covered by cataphyll fibers; roots few, moderately long, descending, 2-3 mm diam.; cataphylls 3-6 cm long, apiculate at apex, drying tan, weathering into dense, tangled, persisting fibers. LEAVES spreading; petioles 8.5-24 cm long, 2-5 mm diam., subterete, shallowly sulcate to weakly flattened adaxially, rounded abaxially; geniculum 0.8-2 cm long; blades moderately thick, oblong to oblong-elliptic or oblong-oblanceolate, acuminate at apex, acute to obtuse or narrowly rounded at base, 15-35 cm long, 3.3-7.5 cm wide, broadest near middle or just above; both surfaces punctate, conspicuously black punctate on lower surface; midrib convexly raised near base above, narrowed toward apex, prominulous below; primary lateral veins 14-20 per side, departing midrib at ca. 45º angle, ± obscure above, scarcely visible below; collective vein arising from the base, scarcely visible above and below, 2-7 mm from margin (often more remote from margin in lower half of blade than in upper half). INFLORESCENCE usually erect-spreading, equalling or shorter than leaves; peduncle 10-27 cm long, 2-3 mm diam., as long as or longer than petioles; spathe green to purple, narrowly lanceolate, 3.4-6 cm long, 1-1.5 cm wide, broadest at base, acuminate at apex, obtuse to rounded at base, inserted at 45º angle on peduncle; stipe 1-6 mm in front, to 3 mm in back, ca. 2 mm diam.; spadix green to brownish-red or purplish-green, 2-15 cm long, 7-9 mm diam. at base, 3-5 mm diam. at apex; flowers rhombic to 4-lobed, 2.1-2.5 mm long, 2-2.5 mm wide, the sides sigmoid; 4-5 flowers visible in the principal spiral, 5-9 flowers visible in the alternate spiral; tepals glossy, densely, weakly and minutely papillate, lateral tepals 1.2-2.5 mm wide, the inner margin convex; pistils emergent 0.3-0.5 mm, white; stigmas elliptic, ca. 0.4 mm long with small droplets before stamens emerge; stamens emerging rapidly from the base, lateral stamens preceding alternates by only 1-2 spirals, exserted on filament ca. 0.5 mm long, which quickly retract to hold anthers at edge of tepals; anthers ca. 0.4 mm long, 0.6 mm wide; thecae white, dish-like, ellipsoid; pollen while. INFRUCTESCENCE with orange, ovoid berries.
