They grow in colonies, with short horizontal stems under or at ground level, forming dense or open clumps, up to 6 m high and 2-6 cm in diameter, with internodes 5-30 cm long. Leaves 4-6, are erect-patent, pinnate 1-2 m long; with pinnae 20-26 on each side, slightly sigmoid or falcate, 25-40 cm long and 2.5-5 cm wide, long acuminate, 2 prominent nerves on each side of the main nerve, rachis 100-120 cm long; tubular sheath, 20-60 cm long, with an elongated triangular extension opposite the petiole insertion, forming auriculated lobes on each side of the petiole. The petiole is up to 35 cm long, abaxially with a pale band that extends to the sheath. Infrafoliar inflorescences, solitary, with peduncle 20-45 cm long, erect in flower, pendulum in fruit, bracts 5-8, rachis 10-20 cm long; inflorescences staminated with 15-30 splints, 20-30 cm long, flexuous and pendulous, green to yellow in flower, flowers 2.5-3.5 mm long and 2.5-3 mm wide, yellow-greenish, sepals free almost to the base, petals valved, free almost to the base; pistillate inflorescences with 10-20 slivers, 20-35 cm long, frequently only bifid, orange and bulging in fruit, flowers 3-3.5 mm long and 2-2.5 mm wide, in lax spirals, pale yellow, slightly sunken, sepals connate briefly at the base, petals imbricated almost to the apex, free. Fruits are globose to subglobose, 7-10 mm in diameter, green when unripe and turning black or black-purple when ripe.
Distribution and ecology
It is found throughout Mexico and Central America, in Guatemala, Honduras, Costa Rica, Nicaragua, Panama, and El Salvador.
It is a common species in humid or very humid forests, cloud forests, and dwarf forests, at an altitude of 600-1650 meters.[1] It tolerates full sun, but is found to prefer shade in hot, inland climates.[2]
