INFLORESCENCES 2--3 per axil; peduncle 9--12.5 cm long, 5--17 mm diam., medium green, minutely white striate, clearly demarcated from the colored spathe; spathe coriaceous, 14--20 cm long, (1.6--1.85 times longer than peduncle), acute at apex; spathe blade green to purplish outside, whitish inside; spathe tube oblong-ellipsoid, purple or maroon outside, purple to reddish inside; spadix sessile, (6)9.5--19 cm long, broadest near the base or above the middle; pistillate portion cylindrical to ellipsoid, 3.2--5.8 cm long, 1.1--1.5 cm diam. at apex, 1.1--1.7 cm diam. at middle, 1.1--1.2 cm wide at base, with 15--17 flowers visible per spiral; staminate portion 6--9.8 cm long; fertile staminate portion white, tapered to clavate, 8--11 mm diam. at base, 7--10 mm diam. at middle, 5--18 mm diam. ca. 1 cm from apex, narrower than or as broad as the pistillate portion; sterile staminate portion as broad as the pistillate portion, 8--11 mm diam.; pistils 1.4--3 mm long, 8--25 mm diam.; ovary 6--8(9)-locular, 9--25 mm diam., with sub-basal, sometimes basal placentation; ovule sac 0.5 mm long; ovules 3--7 per locule, contained within transparent ovule sac, 0.1--0.9 mm long, almost equal in length to funicle, style similar to style type B; style apex flat; stigma discoid, unlobed, 0.6--1.3 mm diam., 0.1--0.4 mm high, covering center of style apex; the androecium truncate, irregularly 4--6-sided, 0.4--0.8 mm diam. at apex; thecae ovate or oblong, 0.2 mm wide; sterile staminate flowers irregularly blunt, 1--2 mm long, 1 mm wide. INFRUCTESCENCE with berries orange, narrowly ovoid-ellipsoid, tapered and obscurely beaked at apex, 1.2 mm long, 9 mm diam.; seeds 2--3 per locule, 0.8--2.8 mm long, 0.2--2.5 mm diam.
