INFLORESCENCES erect, 2--6 per axil; peduncle 3--13 cm long (to 20 cm long in South America), 2--6 mm diam., pale green to whitish, with raised, prominent white striations; spathe semiglossy, 6--14.5 cm long, (0.9--3 times longer than peduncle), sometimes greenish with short white lineations throughout; spathe blade white to pale green (at anthesis), reddish (post-anthesis) (B & K red-purple 7.5/7), short-lineate outside, (opening 4.6 cm long, 3.6 cm wide), very pale green to white, matte, few, sparse, dark-lineate inside; spathe tube semiglossy and greenish to greenish brown or reddish (maroon or reddish at anthesis) outside, green to white inside; spadix weakly exserted from the spathe, 7.6--9.2 cm long, constricted near base of fertile staminate portion; pistillate portion pale green or whitish, cylindrical, 1.4--2.4 cm long, 1 cm diam. at apex, 1.1 cm diam. at middle; staminate portion 5.3--7.6 cm long; fertile staminate portion creamy white, cylindrical to weakly tapered, 0.85--1.5 cm diam. at base, 0.7--1.3 cm diam. at middle, 6--10 mm diam. ca. 1 cm from apex, broadest at the base, narrower than the pistillate portion, narrower than the sterile portion; sterile staminate portion broader than the apical area of the pistillate portion, gray-white, 1.1--1.5 cm diam.; pistils 1.8--2.5 mm long, 1--1.4 mm diam.; ovary 4--6(5-7)-locular; locules 1.3--1.7 mm long, 0.5--0.7 mm diam., with axile placentation; ovules 18--26(23-28) per locule, 2-seriate, 0.2--0.4 mm long, longer than funicle; funicle 0.1--0.2 mm long, adnate to lower part of partition, style 0.2--0.3 mm long, 1--1.4 mm diam., similar to style type B; style apex flat to slightly rounded; stigma subdiscoid, brushlike, unlobed, 1--1.3 mm diam., 0.2--0.6 mm high, covering entire style apex; the androecium truncate, margins 4--6-sided; thecae oblong to obovate, 0.3--0.5 mm wide, more or less parallel to one another, contiguous; sterile staminate flowers blunt, 1.6--1.8 mm long, 1.4--1.5 mm wide.
