INFLORESCENCES erect, 2--4 per axil; peduncle 2.5--14 cm long, 5--8 mm diam., terete, green to reddish, white-lineate; spathe 6.6--11.8 cm long (0.6--2.5 times longer than peduncle), constricted more or less midway; spathe blade lanceolate, pinkish red, tinged green, pale green to white or green, short white lineate outside, 4--6 cm long, (opening broadly elliptic in face view, pinkish red to white, pale greenish white or pale green inside; spathe tube oblong-ellipsoid, dark reddish maroon to reddish purple to green, weakly short dark lineate outside, 2.5--4 cm long, 1.4--3.8 cm diam., pale green to greenish white to pinkish red inside; spadix sessile or very short stipitate; tapered, 6.6--11.8 cm long, broadest near the base; pistillate portion white, yellowish white (post-anthesis), slightly tapered toward the apex and base, (1.6)2--2.7 mm long, 9--11 mm diam. at apex, 1--1.5 cm diam. at middle, (6)10--11 mm wide at base; staminate portion 3.5--7.1 cm long; fertile staminate portion white, cylindrical to tapered, 7--10 mm diam. throughout, 1--1.5 cm diam. at base, 7--10 mm diam. at middle, 4--6 mm diam. ca. 1 cm from apex, narrower than the pistillate portion, as broad as the sterile portion; sterile staminate portion about as the pistillate portion, white, 1--1.5 cm diam.; pistils 1.8--2.3 mm long, 1.1--1.5 mm diam.; ovary (4)5--6-locular, 1.3--1.5 mm diam., locules 1--1.5 mm long, 0.4--0.6 mm diam., with axile placentation; ovules (7-10)16--22 per locule, 2-seriate, 0.2--0.4 mm long, longer than funicle, style similar to style type B; style apex more or less concave, sometimes weakly lobed; stigma subdiscoid, brushlike, lobed or unlobed, 0.9--1.4 mm diam., 0.2--0.5 mm high, covering center of style apex, depressed medially; the androecium truncate, margins irregularly 3--6-sided; thecae oblong, 0.2--0.3 mm wide; sterile staminate flowers blunt, margins irregularly elongate, 13--18 mm long, 9--13 mm wide. INFRUCTESCENCE: Berries creamy white, obovoid, apex truncate; seeds 20 per locule, 1.9 mm long, 0.2 mm diam., with prominent striations running from funicle to apex and slightly spiraling, perpendicular to larger veins.
