Inflorescences 2 together, subtended by membranous cataphylls at anthesis; peduncle stout, ca 45 cm long, much exceeding the cataphylls at anthesis, medium dull purple; spathe 10–12 cm long, constricted about 1/6 of the way from the base; lower part ovoid, grey-green slightly glaucous; spathe limb broadly oblong-lanceolate, 10–30 × 4–8 cm, hooded at anthesis, later reflexed, then deliquescent, membranous, exterior grey-green, interior greenish white; spadix shorter than the spathe, shortly stipitate; pistillate flower zone 1–2 × ca 1.5 cm; ovaries brownish green, ca 3 mm diam., ascending; stigma sessile, weakly 3-lobed, the lobes blunt, tan; sterile interstice narrowing abruptly above the pistillate zone, then equalling the staminate zone, ivory, very slightly narrowed corresponding to the spathe constriction; synandrodia composed of rhombo-hexagonal stamens, ca 2.5 mm diam., the lowermost ones enlarged and very irregular; staminate flower zone cylindrical, ca 3–5 × ca 1.5 cm diam., whitish; synandria rhombo-hexagonal, convex-topped owing to cap-forming synconnective, ca 1.5 mm diam.; appendix elongate-conical, 3–5.5 × 1–2 cm, equalling length of the spadix, only very slightly thicker than the staminate zone at the base, then gradually tapering, white.
