Root-climbing liana or terrestrial (or epiphytic), sometimes acaulescent (?) plant. Leaf blades 60-90 cm long, tricostate with the lateral costae to the largest part of their length running far inside the leaf margin, bifid to more than half their length; the segments ca ro-12(-rs) cm broad, oblonglanceolate to subovate, distinctly acuminate, in older leaves often secondarily split up into 2-3, or more, irregular lobes. Petiole 50-60 cm long or more. Peduncle ro-r6 cm long. Spathes probably 4-6, the lower ones placed with large intervals; only the lowermost spathe known, this rs-r8 cm long, ea 3•5 cm broad, broadly oblanceolate, long-acuminate, coarse. Spa dix subcylindrical, during an thesis 6-7•5 cm long, 2-2.5 cm thick, in fruiting stage 8-ro cm long, ea 3 cm thick. Staminate flowers 4.5-6 mm long; receptacle ea 2 mm diam., elongate, cylinder-shaped; perianthlobes s-6(-8), not connate with the receptacle, 2-2.5 mm long, 0.4-0.6 mm broad, oblong, acute; stamens 25-35, anthers r-1.3 mm long, 0-4-0.5 mm broad, filaments 0 .2-0.3 mm long, basal bulbs medium-sized. Pistillate flowers during late anthesis 4_ 5 mm broad; tepals free, apically unevenly rotundate, ± undulate, somewhat narrowing towards the base, in late flowering stage 3-5-4 mm long, 2-2.5 mm broad at base, 2.5-3 mm broad in their upper part, distim:tly surpassing the stigmas, in fruiting stage as much as s mm long, as much as 4 mm broad; styles rather short, free; stigmas laterally strongly compressed, ± uncinate, seen from above long, narrowly linear, acute, projecting between the tepals, in young fruiting stage distinctly turned upwards. Seeds unknown.
