Morphology

Massive pachycaul with the stem decumbent or erect, to 4 m tall; petioles to 1.3 m long, sheathing in lower third to half; blades ovato-sagittate, bluntly triangular in general outline, held more or less erect, with the margin entire to very slightly sinuate (distinctly sinuate in ‘var. heterophylla'; anterior lobe ca. 70 cm to over 1 m long, ca. 60–90 cm wide at base, with ca. 9 rather distant primary lateral veins on each side of the anterior costa diverging at ca. 60°; glands in axils of primary veins on abaxial side distinct; secondary venation flush with the lamina or but slightly raised abaxially, not forming interprimary collective veins or these poorly defined; posterior lobes ca. third to half the length of the anterior, somewhat rotund, often overlapping; inflorescences paired among the leaf bases, subtended by membranous cataphylls; peduncles barely exceeding the cataphylls at anthesis; spathe rather variable in length, ca. 13–35 cm long, constricted about sixth of the way from the base; lower part green, ovoid; limb broadly oblong-lanceolate, cowl-like at anthesis, later reflexed, then deliquescent, membranous, pale yellow; spadix slightly shorter than the spathe; female zone 1-2 cm long, c. 1.5 cm diam.; ovaries pale green, ca. 3 mm diam.; stigma sessile, 3–5-lobed, the lobes conic, yellow; sterile interstice slightly shorter than to equalling the female zone, whitish, slightly narrowed corresponding to the spathe constriction; male zone cylindric, c. 3–7 cm long, c. 2 cm diam., whitish; synandria rhombo-hexagonal, convex-topped due to cap-forming synconnective; appendix yellowish, slightly thicker than the male zone at the base, thence tapering, equalling to considerably exceeding half the length of the spadix, staminodial; fruiting spathe ca. 8 cm long, green.
