LEAVES spreading; petioles (3.5)6-22 cm long, 4-10 mm diam., sharply D-shaped, slightly thicker than broad, sharply flattened to broadly and shallowly sulcate adaxially, the margins sharply raised to curved inward, rounded to obtusely or acutely angular, sometimes 1-ribbed abaxially; geniculum somewhat thicker and much paler to darker than petiole, 0.7-1.7 cm long; blades subcoriaceous, narrowly oblong elliptic to oblong-linear, long-acuminate to short acuminate (rarely acute) at apex, attenuate to narrowly acute at base, (18)30-79 cm long, (3.2)4- 7(11) cm wide, broadest at or near the middle, the margins flat, weakly revolute; upper surface semiglossy, medium to dark green, lower surface glossy, much paler; midrib convexly raised at base, becoming acutely raised toward the apex above, prominently and acutely raised at base, becoming less pronounced toward the apex below; primary lateral veins 25-55 per side, departing midrib at 40-50° angle, straight to the collective vein, obscure and flat above and below; interprimary veins numerous, almost as conspicuous as primary lateral veins; tertiary veins drying visible; collective vein arising from the base, slightly more prominent than primary lateral veins, 4-6 mm from margin. INFLORESCENCES erect-spreading; peduncle 20-45 cm long, 2-4 mm diam., 1.6-4(5.5)x as long as petiole,pale green, sometimes tinged purplish, subterete to 3-4-ribbed; spathe spreading, rarely reflexed, thin, green to pale green, sometimes tinged with purple at margins, lanceolate-elliptic to linear-lanceolate, (2.5)3-7 cm long, 0.7-1.7 cm wide, broadest near the base, short-acuminate at apex (the acumen somewhat inrolled), acute at base; stipe 2-13 mm long in front and in back; spadix medium green (B & K yellow-green 7/5) to pale green, cylindroid, scarcely tapered, curved, (l.7)4-11(15) cm long, 3-6 mm diam. near base, 2-3 mm diam. near apex; flowers 4-lobed; 2-3 mm in both directions, the sides jaggedly sigmoid, 3-5 flowers visible in principal spiral, 5-7 in alternate spiral; tepals matte, weakly and minutely papillate, droplets present at anthesis; lateral tepals 1-1.8 mm wide, the inner margins straight to broadly rounded, the outer margins irregularly 3-5-sided; pistils weakly raised, green; stigma depressed, 0.2-0.4 mm long; stamens emerging in prompt sequence from the base, the laterals preceding the alternates by 3-11 spirals, held in a tight cluster above the pistil; filaments translucent, 0.4 mm long, 0.5-0.7 mm wide; anthers creamy white, 0.6-0.7 mm long, 0.7-0.9 mm wide; thecae ellipsoid to ovoid, scarcely divaricate; pollen pale yellow fading to white. INFRUCTESCENCE erect to pendent; spathe persisting, green, or absent; spadix 7-16 cm long; berries green becoming purplish to purple-black, obovoid-ellipsoid, quadrangular at apex, 6 mm long, 5 mm diam.
