Epiphyte or terrestrial; stems green, ca. 18 cm long, 2.5-3 cm diam.; roots few, dark greenish-brown, descending; leaf scars 2-3 cm wide; cataphylls coriaceous, 6.5-15 cm long, long-acuminate at apex, drying dark brown, splitting at base, subpersistent. LEAVES with petioles erect to spreading, 29-56 cm long, 5-7 mm diam., terete; geniculum 1-4.5 cm long; blades oblanceolate to oblong-ovate, moderately thick, long-acuminate at apex, lobed at base, 33-56 cm long, 14-28 cm wide, broadest just below middle; anterior lobe 34-40.5 cm long, the margins convex; posterior lobes 4.5-10 cm long; the sinus parabolic to triangular, sometimes the lobes overlapping, acute at apex; upper surface semiglossy to glossy, lower surface semiglossy, obscurely to conspicuously punctate; the midrib prominulous, convex above, more prominently raised below; basal veins 3-5 pairs, usually free, sunken or prominulous in valleys above, raised below; primary lateral veins 8-12 per side, departing midrib at 35°-50° angle, sunken above, raised below, arcuate-ascending to collective vein; lesser veins flat to weakly sunken above, flat below; collective vein arising from the first basal vein, sunken above, raised below, 5-10 mm from margin. INFLORESCENCE erect-spreading, longer than leaves; peduncle 30-80 cm long, 3-8 mm diam., terete; spathe subcoriaceous, green sometimes faintly tinged purplish (B & K Yellow-green 8/10), oblong-lanceolate, 9-14.5 cm long, 1.5-2.2 cm wide, narrowly acuminate at apex, obtuse at base, inserted on peduncle at 30°-50° angle; spadix olive-green (B & K Yellow-green 6/5) to dark purple (B & K Blue-purple 2/10), 9-35 cm long, 7-9 mm diam. at base, 2-4 mm diam. at apex; flowers rhombic to 4-lobed, 2.5-4 mm long, 2.3-3 mm wide, the sides ± straight parallel to spiral, gradually sigmoid perpendicular to spiral; 6-7 flowers visible in the principal spiral, 7-9 flowers visible in the alternate spiral; tepals glossy, minutely papillate, sometimes with droplets as stamens emerge, lateral tepals 0.8-1 mm wide, the inner margin broadly rounded; pistils weakly emergent, green tinged with red-violet; stigma oblong-linear, 0.5-0.6 mm long, purplish with droplets apparent a few days before stamens emerge; stamens emerging from the base, the lateral stamens preceding alternates by 1 -2 spirals, exserted briefly on pinkish flattened filaments, which retract, holding stamens at edge of tepals against pistil; anthers pale yellow, held ± contiguous, 0.3-0.4 mm long, 0.5-0.6 mm wide; thecae ellipsoid; pollen yellow to white, fading to cream. INFRUCTESCENCE pendent, spathe withered; berries subglobose to obovoid, rounded at apex, red to red-orange (B & K Red 6/7.5), 8-8.5 mm long, 5.5-6.5 mm wide; mesocarp fleshy, ± transparent with raphide cells; seeds 1-2, ovoid, cream or greenish-white. 4 mm long, 2.5 mm wide, 2 mm thick with sticky appendages at both ends.
