Pachycaul herbs, massive, to 2.5m, evergreen, with slightly milky latex. Stem erect to decumbent, with short stolons terminating in tubercles arising from base. Leaves several to rather many together, clustered at tips of stems of larger plants; petiole up to 1.5m, sheath membranous; leaf blade peltate, cordate-sagittate or cordate-ovate, up to 130 × 100cm, basal margins undulate, apex shortly acuminate; primary lateral veins 9–12 on each side, interprimary veins forming well defined interprimary collective veins. Inflorescences 2 or 3 together among leaf bases, subtended by membranous cataphylls; peduncle stout, ca. 35 cm, exceeding cataphylls at anthesis. Spathe 13–25cm, constricted ca. 1/6 of way from base; proximal part green, ovoid; limb cowl-like at anthesis, later reflexed, then deliquescent, greenish white, broadly oblonglanceolate, 10–30 × 4–8cm, membranous. Spadix shorter than spathe, shortly stipitate; female zone 1–2 × ca. 1.5cm; pistil pale green, ca. 3 mm in diam.; stigma sessile, weakly 3-lobed, lobes blunt, pale green; sterile zone equaling male zone, ivory, very slightly narrowed corresponding to spathe constriction; synandrodes rhombic-hexagonal, ca. 2.5mm in diam.; male zone whitish, cylindric, 3–5 × ca. 2cm; synandria rhombichexagonal, convex-topped due to cap-forming synconnective, ca. 1.5 mm in diam.; appendix white, narrowly conic, 3–5.5 × 1–2cm, equaling ca. 1/3 length of spadix, markedly thicker than male zone at base, slowly tapering toward apex. Fruiting spathe ca. 6cm. Fruit ripening scarlet, globose, ca. 1cm in diam.
