INFLORESCENCE erect-spreading, shorter than leaves; peduncles 18-20 cm long, 4-5 mm diam., terete, green heavily tinged with red-violet, one third to one half as long as petioles; spathe coriaceous, green tinged with red-violet, broadly lanceolate, 7.5-9 cm long, 2.5-3 cm wide, broadest at base, acuminate at apex, subcordate at base, inserted at 45° on peduncle; stipe 2-2.5 cm long in front, 1.5-1.8 cm long in back, 5 mm wide, green tinged with red-violet; spadix green (B & K Yellow-green, 6/7.5), 8-8.2 cm long, 1.2-1.5 cm diam. at base, 7-9 mm diam. at apex; flowers rhombic to 4-lobed, 3-3.2 mm long, 4-4.5 mm wide, the sides sigmoid; ca. 5 flowers visible in the principal spiral, ca. 7 flowers visible in the alternate spiral; tepals matte, weakly punctate, densely and minutely papillate, lateral tepals ca. 2.3 mm wide, the inner margin straight; pistils emergent, weakly raised, green; stigma linear, nearly obscure; lateral stamens emerging from base to apex, rapidly followed by third and fourth, exserted on short, translucent filaments; anthers yellow, ca. 0.5 mm long, 0.3 mm wide, held in a contiguous circle over pistil then retracting and opening at edge of tepals; thecae ellipsoid, scarcely divaricate; pollen yellow, fading to white. INFRUCTESCENCE pendent; berries dark orange, ovoid, 1.2-1.5 cm long, 1.2-1.4 cm diam., rounded at apex with 4 faint ridges; seeds 2, green, 1-1.3 cm long, 7-8 mm thick, markedly flattened on one side.
