Herb to c. 75 cm tall. Stem condensed, more or less creeping, c. 2–2.5 cm thick, bright red internally (?always), with internodes to c. 0.5 cm long, pleionanthic. Leaves to c. 8 together; petiole 30–55 cm long, tinged reddish towards the base (?always), drying rust-brown, sheathing only at the extreme base, the wings of the sheath extended into a bicarinate narrowly lanceolate ligular portion 15–22 cm long, this drying dark brown; blade ovate, 15–30 cm long × 7–15 cm wide, dark green adaxially, abaxially paler, the base obtuse (sometimes slightly decurrent), not at all cordate, the tip acute and acuminate for up to c. 3 cm; midrib very prominent abaxially (dry), adaxially flush with the lamina, with 18–26 primary lateral veins on each side, irregularly alternating with interprimary veins and diverging at 60–70°; secondary venation rather obscure, arising from the midrib and from the bases of the primary veins; tertiary venation obscure. Inflorescences 1–4 together subtended by lanceolate cataphylls resembling the ligular leaf sheaths; peduncle to 10 cm long, not exceeding the cataphylls. Spathe 8 cm long; lower spathe 3.5 cm long, green, differentiated from the limb by a weak constriction level with the top of the interstice; limb 5 cm long, becoming white, caducous. Spadix 6.5 cm long, subcylindric; female zone 3 cm long, adnate to the spathe in the lower ⅔, the free part slightly conoid, apically 4 mm diam.; pistils numerous and crowded, subcylindric, c. 0.4 mm diam.; stigma sessile, about the diameter of the ovary, button-like, papillate; interpistillar staminodes very few among the pistils, otherwise confined to a single row along the spathe/spadix adnation, about the height and diameter of the pistils, subcylindric, flat-topped; sterile interstice 6 mm long, white, somewhat obconoid, distally 6 mm diam.; staminodes of interstice crowded, irregularly polygonal, 0.5–1 mm diam., flat-topped; male zone 3 cm long, finger-like, basally isodiametric with top of interstice, tapering to a blunt point in the upper half; stamens somewhat lax, truncate, flat-topped, somewhat irregularly rectangular with the connective wide and the pores small on the narrower edges of the connective, 0.5–0.7 mm across; appendix absent. Fruiting spathe narrowly urceolate, 4 cm long.
