INFLORESCENCES erect to erect-spreading, (1)2-3 per axil; peduncle 2-9 cm long, 8÷14 cm diam., pinkish red. white striate, especially toward apex; spathe 10-17 cm long (1.9-7 times longer than peduncle), weakly constricted, oblong-ellipsoid; spathe blade light green outside, cream, pale li-neate in upper one-half inside; spathe tube green, tinged red outside, 6-9 cm long, red with conspicuous resin canals inside; spadix tapered to somewhat ovate, weakly protruding, 8.8 -14.4 cm long; pistillate portion weakly ovoid, whitish, (2)3 - 4.9 cm long, 2-2.4 cm diam. throughout, 1.4-1.5 cm diam. at apex, 1.4 - 1.9 cm diam. at middle, 1.4 - 1.8 cm wide at base; staminate portion 5.7-10.8 cm long; fertile staminate portion bluntly tapered at apex, 1.1÷1.4 cm diam. at base, 1.2 - 2.3 cm diam. at middle, 1(1.7) cm diam. ca. 1 cm from apex, broadest at upper two-thirds, broader than the pistillate portion, slightly narrower than the sterile portion; sterile staminate portion broader than the pistillate portion, 1.4 - 2.5 cm diam.; pistils (1)3÷ 3.9 mm long, 1.5 - 1.9(3.8) mm diam., margins broadly rounded and slightly raised above the apex; ovary 4-6-locular, 1.9-2.5 mm long, 1.3-1.9(3.8) mm diam., with axilc placentation; locules 1.9-2.5 mm long, 0.4 - 0.7 mm diam.; ovule sac not present or to 1.9 mm long; ovules 10-14(18) per locule, 2-seriate, rarely contained within translucent or transparent envelope, 0.1 - 0.3 mm long, longer than funicle; funicle 0.1-0.3 mm long, adnate to lower part of partition, style 0.8 - 1.2 mm long, 1.5 - 1.9(3.6) mm diam., similar to style type B; style apex barely raised, button-like, broadly concave, medial apex with a whitened margin, raised and apparently like type D on drying; stigma subdis-coid, truncate, 1.4-1.6 mm diam., 0.3 - 0.4 mm high, covering ± entire style apex, sometimes depressed shallowly and medially; the androecium truncate, oblong, prismatic, margins irregularly 4 - 5-sided, sometimes scalloped, 1 mm long, 1.8 - 2.1 mm diam. at apex; thecae ± oblong, 0.4-0.5 mm wide, ± parallel to one another; sterile, staminale flowers blunt, irregularly 4--6-sided, prismatic, 2.5 - 3.5 mm long, (1.4)1.8-2.2 mm wide. INFRUCTESCENCE with pistillate spadix 5 - 6 cm long, 3.5 cm diam.; berries white, 1.1 cm long, 4 - 4.6 mm diam.; seeds 1.4 mm long, 0.5 mm diam., cream-colored.
