    General Description
    Epiphytic or terrestrial; stem to 100 cm long, ca. 1.5-2 cm diam.; leaf scars occasionally conspicuous, 0.7-1 cm high, 1.5-1.7 cm wide; roots moderately numerous, descending, greenish, pubescent, sometimes smooth, moderately thick and elongate, blunt, 3-7 mm diam.; cataphylls subcoriaceous, 6-30 cm long, subrounded at apex with subapical apiculum, green tinged with red, drying tan (B & K yellow-red 9/2.5), persisting semi-intact, eventually deciduous. LEAVES spreading; petioles 11-150 cm long, 5-15 mm diam., erect-spreading, subterete to nearly D-shaped, shallowly and narrowly sulcate to flattened adaxially, rounded abaxially, the surface faintly pale speckled; geniculum slightly thicker and paler than petiole, 1.5-3 cm long; blades moderately coriaceous, somewhat pliable, narrowly ovate to ovate-deltoid to ovate-triangular, acuminate at apex (the acumen apiculate), shallowly or deeply lobed at base, 17-64 cm long, 9-34 cm wide, broadest between the base and middle, the margins undulate; anterior lobe 12-29 cm long, the posterior lobes 7-13 cm long; sinus arcuate to parabolic; both surfaces semiglossy to glossy, medium to dark green above, much paler below; midrib bluntly angular to convexly raised above (rarely acutely angular), much paler than surface, round-raised at base, becoming prominently and convexly raised toward the apex, paler than surface below; basal veins 3-6 pairs, 1st usually free to base, 3rd to 6th coalesced 1-2 cm, 4th to 6th coalesced 3.5-6 cm, raised above and below; posterior rib naked, turned up on outer margin; primary lateral veins 4-9 per side, departing midrib at 40-50° angle, broadly arcuate, weakly raised above and below, more so below; interprimary veins flat above, weakly raised below, less conspicuous than primary lateral veins; tertiary veins weakly visible above and below; collective vein arising from one of the primary lateral veins, sometimes from the first basal vein, raised to weakly sunken above, raised below, 2-10 mm from margin. INFLORESCENCES erect to erect-spreading, much shorter than leaves; peduncle 13-100 cm long, 5 mm diam., 0.6-0.7 x as long as petiole, green to purplish, terete; spathe spreading, hooded over the spadix, recurled at apex, subcoriaceous, green to green tinged with purple to purple or maroon, lanceolate to narrowly ovate, 4-35 cm long, 2-6.5 cm wide, broadest near the base, acute and apiculate at apex (the acumen tightly inrolled), truncate at base; stipe 1.6 cm long in front, 1.3 cm long in back; spadix pink to red to dark violet-purple to maroon, weakly tapered, 3.5-19 cm long, 9-15 mm diam. near base, 6-9 mm diam. near apex; flowers rhombic, 2-3.2 mm long, 2.6- 3(5) mm wide, the sides jaggedly sigmoid; 5-10 flowers visible in principal spiral, 7-20 in alternate spiral; tepals matte, sparsely punctate, moderately papillate; lateral tepals 1-1.8 mm wide, difficult to discern, the inner margins broadly rounded, the outer margins 3-4-sided; pistils not emergent, pale green; stigma slitlike, ca. 0.5 mm long; stamens emerging promptly throughout in a scattered pattern, becoming prominently exserted, lateral stamens emerging almost to apex before alternates emerge, surmounting tepals; filaments fleshy, somewhat flattened, translucent, ca. 0.5 mm long, ca. 1 mm wide; anthers creamy white to pale orange, ca. 0.6 mm long, 0.7 mm wide; thecae ovoid-ellipsoid, slightly divaricate; pollen yellow to yellow-orange, fading to white, yeasty-scented. INFRUCTESCENCE arching-pendent; spathe persisting; spadix to 50 cm long, to 3 cm diam.; berries orange, narrowly obovoid, acute at apex, 12-14 mm long, 6 mm diam.; mesocarp bitter; seeds 1-2 per berry.
