INFLORESCENCES with peduncle 49-63.5 cm long, 3-7 mm diam., 6.1- 7.5 x as long as petiole, probably terete; spathe apparently erect to spreading, coriaceous, green, oblong-lanceolate, 9-16 cm long, 1.5-2.5 cm wide, broadest near the base, shortly acuminate at apex (the acumen inrolled, 7-1 5 mm long), acute at base; stipe 1.5-4(7) cm long in front, 0.5- 1.5(2.5) cm long in back; spadix dark purple-red to brown-red, long-tapered, somewhat curved, held at 150-165° angle from peduncle, (9)15-18(21) cm long, 6-7(10) mm diam. near base, 4-6 mm diam. near apex; flowers rhombic, 4-4.6 mm long, 2.5-2.8 mm wide, the sides straight; 7-8 flowers visible in principal spiral, 5-6 in alternate spiral; tepals minutely papillate, semiglossy on drying; lateral tepals 2.3-2.8 mm wide, the inner margins broadly rounded, the outer margins 2-sided; pistils minutely papillate; stigma slitlike, 0.4-0.5 mm long; anthers 0.4-0.5 mm long, 0.5-0.6 mm wide, contiguous, obscuring pistil; thecae oblong, not at all or slightly divaricate; pollen fading to white.
