SUMMARY
Terrestrial herb, in the plants observed up to 81 - 96 cm tall, growing in humid, shady forests. Stem small ["caudiculus"] probably abbreviated. LEAVES rigidly erect, coriaceous, adaxially appearing dark green when alive, abaxially paler; petiole thick, laterally compressed, sulcate, longer than the blade, 55 cm long or longer, 10 mm in diam. or greater when alive. Adult leaf blade glabrous, minutely black-punctulate on both surfaces (more densely so on lower surface), ovate, rounded at the apex, shortly attenuate at the base, somewhat thickened at the margin, more-or-less 44 cm long, 35 cm wide, six-veined with the midrib, uppermost primary lateral veins running into the apex, the two outermost in the lower half of the leaf running near to the thicker margin and disappearing into it, the secondary veins parallel, slender, 1.5 - 2 cm distant from one another, tertiary veins many, very slender. INFLORESCENCES up to 62 cm tall or taller, erect but apparently with a nutant spadix, peduncle similar to petiole, up to 12 mm ["cm"] in diameter. Spathe coriaceous, broadly lanceolate, acute at the apex, 8 - 9 cm long, 2 - 2.4 cm wide, completely glabrous, green. Spadix cylindric, rounded-obtuse at the apex, 20 - 22 cm long, when dried 3.5 cm in diameter, stipitate, green. INFRUCTESCENCE: Berries oblong, tetragonal, produced into a prismatic style.
