INFLORESCENCES 1--3 per axil; peduncle 4.5--8 cm long, to 4 mm diam., pinkish red, coarsely white lineate toward apex, drying blackened; spathe 8--20 cm long, 1--2 cm diam. when furled, to 5.5 cm wide when open (7--11 cm wide when fully flattened), (2.5)3--3.7 times longer than peduncles, acuminate at apex (acumen 2.5 cm long), semiglossy, in Central America, pale yellow-green, darker green toward middle, white along margins, sometimes tinged with pink, the open margin sometimes violet-purple outside; greenish white and matte throughout within, in South America, spathe tube somtimes reddish outside, dark red to red-violet, suffused onto lower one-half of blade inside; spathe blade to 15 cm long, white within; spathe tube 7.5--8.5 cm long, to 4.3 cm diam. at anthesis; spadix weakly stipitate; 14--15.5 cm long; pistillate spadix (3.4)4--4.3 cm long in front, 2.8--4 cm long in back, 11--16 mm diam. at apex, 1.2--1.8 cm diam. at middle and base; staminate portion 10--13 cm long, 1.2--1.5 cm diam. at base, 1.5--1.8 mm diam. midway, 8--12 mm diam. 1 cm from apex, constricted to 1.5 cm diam. above the sterile portion; sterile staminate portion to 3.4 cm long, 20 cm diam. at base, 10--18 mm diam. at apex; pistils 1.1--2.4(3.5) mm long, 1.2--5 mm diam.; ovary 5--6-locular, with axile placentation; locules 1.3--1.6 mm long; ovules 19--25 per locule, 2--3-seriate, ca. (0.1)0.25--0.3 mm long; funicle as long as or shorter than ovules, 1/3-2/3 as long as the ovule; stigma 1--1.5 mm diam., depressed medially; style similar to style type B, 1 mm diam.; style apex flat to weakly concave; stylar canals arising at base of apical depressions; stigma discoid, 0.8 mm thick, 1.5--18. mm diam.; the androecium truncate to more or less prismatic, margins irregularly 4--6-sided, many 6-sided, ca. 0.6 mm long; thecae oblong, more or less parallel to one another; sterile staminate flowers clavate, irregularly 4--5-sided to ovoid, 0.9--1.3 mm long.
