LEAVES erect-spreading; petioles 90-140 cm long, 1-1.5 cm diam., subterete, narrowly and obtusely sulcate; geniculum 3-3.5 cm long; blades ovate, moderately thick, short-acuminate at apex (the acumen minutely apiculate), deeply lobed at base, 35-70 cm long, 26-50 cm wide, broadest near point of petiole attachment; anterior lobe 25-48 cm long, the margins broadly convex; posterior lobes 12-22 cm long, directed downward; the sinus hippocrepiform, rounded to obtuse at apex; both surfaces semiglossy; midrib convexly raised above, diminished and sunken toward apex, acutely raised below; basal veins 5-7 pairs, up to 5 of them coalesced 2.5-6 cm, raised above and below, the posterior rib broadly curved, naked; primary lateral veins 4-7 per side, departing midrib at ca. 55° angle, then spreading at 35°-45° angle, loop-connected, sunken above, raised below; lesser veins less conspicuous; collective vein arising from uppermost basal vein, 5-15 mm from the margin. INFLORESCENCE usually slightly shorter than or about as long as the leaves; peduncle 43-110 cm long, to ca. 8 mm diam. midway, half as long as or equalling the petioles; spathe moderately coriaceous, pale green (B & K Yellow-green 8/7.5), ovate-elliptic, 7-12 cm long, 3.5-5 cm wide, broadest 1-2 cm above point of attachment, cuspidate-acuminate at apex (the acumen inrolled, 6-10 mm long), acute to obtuse at base, inserted on peduncle at ca. 80° angle; stipe 1-6 cm long in front, 2-8 mm long in back, ca. 6 mm diam.; spadix clavate, green (B & K Yellow-green 8/10) to orange-tan, 4.5- 7.5 cm long, 1.2-1.5 cm diam. at base, 1.5-2.2 cm diam. at apex; flowers 4-lobed, (1.4)2.3-2.7 mm (dry) in both directions, the sides sigmoid; 20 or more flowers visible in the principal spiral, 13-16 flowers visible in the alternate spiral; tepals semiglossy, the lateral tepals 1.2-1.3 mm wide (dry), the inner margin broadly rounded; pistil emergent but not raised, green; stigma oblong-elliptic, slitlike, ca. 0.5 mm long; stamens emerging, scattered, beginning near the middle, the lateral stamens exserted throughout the spadix before the alternates emerge; anthers white, held in a moderately close circle, contiguous or nearly so at upper edge of tepals, ca. 0.4 mm long and 0.5 mm wide; thecae ovate, moderately divaricate; pollen white. Immature INFRUCTESCENCE to 10 cm long and 3.3 cm wide; berries not seen.
