LEAVES erect to spreading; petioles 7-19 cm long, 3-10 mm diam., erect, sharply D-shaped, broadly convex to 1 -ribbed to flattened or somewhat sulcate with the margins sharply raised or sharp but not raised adaxially, rounded to weakly 1 -ribbed abaxially; geniculum moderately thicker and paler than petiole, becoming transversely fissured with age, 0.5-3 cm long; sheath 2-5 cm long; blades subcoriaceous to moderately coriaceous, broadly elliptic to broadly oblanceolate to oblanceolate, long-acuminate at apex (the acumen apiculate), long-attenuate to attenuate, rarely acute at base, (15)30-60(90) cm long, 8-27 cm wide, broadest near or above the middle, the margins undulate; upper surface weakly glossy to semiglossy, medium green (B & K green 2/2.5), lower surface semiglossy, conspicuously paler, both drying brown to greenish brown; midrib flat and 1 –ribbed at base, becoming acutely angular toward the apex above, higher than broad at base, becoming obtusely angular and then convexly raised at apex below; primary lateral veins 5-lO(16) per side, departing midrib at 40-80º angle, straight to less often arcuate to the margin, paler than surface, convexly raised above and below, more so above; tertiary veins obscure above, prominulous and darker than surface below; collective vein arising from about the middle of the blade, near the apex or absent, prominulous on both surfaces, to 12 mm from margin. INFLORESCENCES erect to spreading; peduncle 23-50 cm long, 3-4 mm diam., 2-4.6 x as long as petioles, yellowish green tinged with reddish in the lower half or purple, terete; spathe spreading to reflexed, subcoriaceous, concolorous with the petiole, sometimes tinged with purple or purple throughout, ovate-lanceolate to oblong-lanceolate, 4.5-15 cm long, 0.9-1.9 cm wide, inserted at 60º angle on peduncle, acuminate at apex (the acumen inrolled), rounded to obtuse at base; spadix purple to maroon (B & K red-purple 2/10) to yellowish green, sessile or stipitate to 5 mm, cylindroid to slightly tapered, erect to somewhat curved, (3)4-16 cm long, 4-6 mm diam. near base, 3-4 mm diam. near apex; flowers 4-lobed, 1.5-2.5 mm in both directions, the sides straight to jaggedly sigmoid; 4-6 flowers visible in principal spiral, 4-8 in alternate spiral; tepals matte, white-punctulate; lateral tepals 0.8-1.5 mm wide, the inner margins broadly rounded, the outer margins 2-3- sided; pistil weakly raised; stigma slitlike to ellipsoid, 0.4-0.6 mm long; stamens emerging irregularly, the laterals preceding the alternates by up to 16 spirals, the 3rd stamen preceding the 4th by 3-4 spirals, borne at edge of the tepals; anthers pinkish to reddish or orangish, 0.4-0.7 mm long, 0.6-0.8 mm wide; thecae ellipsoid, divaricate; pollen yellow to pale yellow, sometimes fading to white and then turning lavender. INFRUCTESCENCE with spathe persisting, peduncle 38-44 cm long; berries deep purple, obovoid; seeds 2 per berry.
