Flowers 1.6-2.0 mm long, 1.8--2.1 mm wide, 10-12 per spiral; tepals triangular; stamens long-exserted; pistils early emergent INFRUCTESCENCES long-pendent; fruiting spadix 50-65 cm long, 2.5 cm or more in diam. at base, to 3 cm diam. at middle, 1.4 cm diam. at apex; tepals blackened; berries reddish-purple, green at tip.
