Terrestrial; juvenile plants with internodes to 8 cm long with petioles 20-25 cm long, terete, narrowly and obscurely sulcate to flattened adaxially, medium green, semiglossy; blades 20-30 cm long, 8-11 cm wide; adult internodes short 1.8-4 cm diam.; cataphylls dark brown, semi-intact at apex, but with loose, semi-organized, red-brown fibers lower on stem, 6-8 cm long; petioles 75-107(-142) cm long (averaging 93.2 cm), 5-8 mm diam. at middle, medium green, weakly glossy, moderately flexible, and many-ribbed circumferentially, sharply C-shaped, sulcate with narrow, bluntly acute-raised margins, many-ribbed circumferentially or sometimes acutely ridged along one side near the base, the opposite side faintly 3-ribbed, semiglossy, medium to dark green, drying light to dark brown; blades ovate to narrowly ovate-elliptic to triangular-ovate, caudate-acuminate at apex, 36-58(-78) cm long, 18-33(-42) cm wide (averaging 50 x 27 cm), 1.6-2.6 times longer than wide, .4-.8 times as long as petiole, subcoriaceous, dark green and semiglossy to matte-sub-velvety above, slightly paler to moderately paler and almost matte to weakly glossy to semiglossy below, subcoriaceous; anterior lobe 31-48(-72) cm long, margins convex; posterior lobes 6-10 cm long, 11-14 cm wide, directed inward, often overlapping, directed toward base, 4-10 cm long, 8-13 cm wide; sinus triangular, 2-8 cm deep; basal veins 5-7 pairs, normally free to base, on occasion 4th and 5th fused at about 1 cm, all join collective vein; midrib narrowly rounded and paler above, convex at base becoming bluntly acute toward apex, round-raised and paler below with marginal acute ribs or many-ribbed below, often acutely 5-ridged below; primary lateral veins 13-15(-20) pairs usually offset, arising at 20-45(-60)°, slightly to deeply sunken and concolorous above, round-raised to raised knife-like and slightly paler below; collective vein arising from lowermost basal vein, 3-4 mm from margin; tertiary veins weak and sunken above, some are more obvious below. INFLORESCENCES erect or erect-spreading; peduncle (10-)25-57 cm long, 27 mm diam., dries typically to brown; spathe 4.5-8 cm long, 1.0-1.5 cm diam., pale green to almost white, tinged with maroon or purple on inner surface, the margins wavy, sometimes reflexed, usually prominently twisted or undulate along the margins; spadix cylindroid, 5-15 cm long, .5-1.2 cm diam., pinkish to dark violet-purple. Flowers 6-8 on primary spiral, 1.5-2.0 mm long, 1.4-1.7 mm wide; the tepals glossy to semiglossy, becoming brownish; pistils early emergent. INFRUCTESCENCES 17-24 cm long, 22-27 mm diam. with berries partly emergent; berries exserted, ovate, acute at apex, 8-10 mm long, 4-5 mm diam., pointed at apex, bright red in apical 1/2-3/5, white below; seeds greenish white, 4-5 mm long, 3 mm wide, 2 mm thick with a short sticky appendage.
