INFLORESCENCES semi-erect to spreading or pendent, shorter than, or almost equalling leaves; peduncle 30-60(98) cm long, 3-10 mm diam. 2-7 x as long as petioles, green weakly tinged with red, pale short-lineate, terete to subterete, occasionally ribbed abaxially; spathe spreading to reflexed, sometimes twisted, occasionally with prominently revolute margins, subcoriaceous, matte above and below, green to green heavily tinged with red or purple-violet (especially on adaxial surface), oblong-lanceolate to oblong-triangular, (6)l0- 32(55) cm long, (1)2-3.5(4.0) cm wide, broadest near the base, inserted at 20-35° angle on peduncle, long-acuminate to abruptly short-acuminate at apex (the acumen often inrolled, 15-20 mm long), acute or decurrent to 6.5 cm at base; stipe rarely to 14 mm; spadix glaucous, bluish green, sometimes weakly tinged with purple or yellow, very long-tapered, ± erect to pendent and curved upward, (7.5)14-33 cm long, 5-12 mm diam. near base, 3-4 mm diam. near apex, broadest at the base; flowers rhombic, (1.6)1.8-3 mm long, (1)1.4-2.6 mm wide, the sides straight to jaggedly sigmoid; (5)6-9 flowers visible in principal spiral, 8-13 in alternate spiral; tepals glaucous, matte, minutely papillate, with a few scattered droplets, lateral tepals 1-1.6 mm wide, the inner margins broadly convex to straight, the outer margins ± straight or bluntly angled to obtusely 3-sided; pistils emergent, papillate, matte, squarish, pale green; stigma ellipsoid becoming circular, 0.4-0.6 mm long; stamens emerging rapidly in a regular and complete sequence over a 5-6-day period, the laterals preceding the alternates by (3)l0- 14 spirals, the 3rd stamen preceding the 4th by 1-3 spirals, inclined over and obscuring pistil; anthers pale yellow, 0.2-0.8 (dried) to 1 (fresh) mm long, 0.4-0.9 mm wide when fresh; thecae oblong, not divaricate; pollen pale yellow fading to cream, sweetly scented like rotting fruit. INFRUCTESCENCE with spathe persisting; spadix 12-53 cm long, 1.5- 3.5 cm diam.; berries reddish purple, obovoid to oblong, 7-1 2 mm long, 4-5.5 mm diam.; pericarp thin, with raphide cells; mesocarp gelatinous; seeds 1-2 per berry, oblong, 4-5 mm long, 1.6-2.2 mm diam., 1-1.2 mm thick, with a mucilaginous appendage.
