LEAVES erect-spreading; petioles 24-109 cm long, 6-15 mm diam., subterete, shallowly and bluntly sulcate; geniculum 1.5-5 cm long; blades ovate to narrowly ovate, subcoriaceous, usually weakly bullate, abruptly to gradually acuminate at apex, prominently lobed at base, 46-120 cm long, 30-69 cm wide, broadest at point of petiole attachment; anterior lobe 26-90 cm long, the margins ± straight; posterior lobes 12-30 cm long, flat or directed inward, often overlapping, the sinus spathulate, obovate or hippocrepiform, broadly acute to obtuse or rounded at apex; upper surface semiglossy or almost matte; lower surface matte; midrib sharply raised in a weak valley above, diminished and sunken near apex, convexly raised below, sometimes weakly ribbed or striate; basal veins 4-9 pairs, (second) fourth to seventh coalesced (2)4.5-9 cm, raised above and below, the posterior rib stout, curved or nearly straight, naked, rolled up along the outer margin; primary lateral veins 9-18 per side, departing midrib at 55° angle, ± straight to slightly ascending to a weak collective vein, sharply raised in weak valleys above, raised below; collective vein usually arising from fourth or fifth basal vein, sunken above and raised below, 1-4(10) mm from the margin, loop-connecting the basal and primary lateral veins. INFLORESCENCE erect, much shorter than the leaves; peduncle 6-54 cm long, 8-13 mm diam., subterete or terete, as long as petioles; spathe thin, pale green (B & K Yellow-green 7/10), lanceolate-oblong, 10-28 cm long, 3.3-4.8 cm wide, broadest in lower third, sometimes erect, usually spreading to reflexed, often twisted and rolled up, inserted at 10°-30° angle on peduncle; spadix sessile, pale green (B & K Green 8/2.5), (3)7-18(28) cm long, 10-20 mm diam. at base, 6-12 mm diam. at apex; flowers 4-lobed, to 1.8 mm long, to 1.5 mm wide, the sides jaggedly sigmoid; 12-15 flowers visible in the principal spiral, 17-19 flowers visible in the alternate spiral; tepals semiglossy, the lateral tepals to 1 mm wide, the inner margin ± straight; pistils slightly emergent, very glossy, whitish green with darker green stigmatic area; the stigma elliptic, 0.2 mm long, glossy, exserted with glistening papillae; stamens emerging scattered throughout the spadix, sometimes with the alternate stamens preceding the lateral ones; filaments ca. 1 mm long, anthers pale yellow, ca. 4 mm long and 5-6 mm wide; thecae oblong; pollen yellow, fading white. INFRUCTESCENCE usually pendent, spathe often absent; spadix 15-40 cm long, to 2.5 cm diam.; berries ovate to ovate-elliptic, acute to rounded and green at apex, greenish-white to yellowish-green at base (white fide label of Alien 2419) to 9 mm long, ca. 5 mm wide; seeds 2, oblong and ± flattened, dark brown, 3.5-5 mm long, 2.2-2.4 mm wide, 1.5-1.8 mm thick.
