Description

Rather large species; internodes keeled and compressed especially below node, sometimes to 10-12 cm long; lowest lateral internodes terete; basal cataphylls 1-4 pairs, highest 2-5 cm above axil. Petiole ca. 1 cm long; blade lanceolate to narrowly ovate, to 17 x 7 cm, commonly half this size, apex acute; venation obscure but pinnate. Monoecious. Inflorescence axillary and at older nodes, each with 0-4 pairs of sterile cataphylls and 6-10 fertile internodes; flowers 5-7 per fertile bract, 2-seriate, terminal flower perhaps always male, others female. Fruit white, ovoid, 0.3 x 0.2 cm, perianth segments closed.

Distribution

Amazon Basin, Bolivar present, C America present, Guianas, Northern America: Mexico Southeast (Chiapas present), Southern America: Bolivia (Bolivia present); Peru (Peru present); Venezuela (Venezuela present), Terr. Roraima present, tropical S America present, western Guyana
Mexico (Chiapas), C America, the Caribbean, throughout tropical S America to amazonian Peru and Bolivia; no records have been seen from the Guianas and the Amazon Basin, but it will almost certainly be found there eventually, at least in western Guyana, it is known from adjacent Venezuela (Bolívar) and Brazil (Terr. Roraima).
