Trees to about 10 m. tall or more, with stout seldom-branching trunks, the young branches stout, ferruginous-hirtellous to glabrate. Mature leaves divided nearly to the center, scabridulous above, paler and minutely cinereous beneath, the lobes usually 9-13, conspicuously contracted toward the base, rounded to shortly acuminate at the tip, the petioles rather slender, minutely ferruginous-hirtellous, with the basal pulvinus densely ferruginous-velutinous. Staminate spadices usually in clusters of 3, 12-16 cm. long and about 4 mm. thick, subsessile or with slender puberulent stipes to about 5 mm. long, the spathes 12-20 cm. long shortly before anthesis, narrowly oblongoid-fusiform and frequently somewhat falcate, rather sparsely arachnoid-villosulose, the common peduncle about 5-10 cm. long, relatively slender. Pistillate spadices in clusters of 3-4, 25-30 cm. long and about 5 mm. thick at anthesis, somewhat accrescent in fruit, sessile or with a very indefinite stipe, the spathes about 16-20 cm. long shortly before anthesis,

A tropical plant. It grows in forest clearings and near the edges of forests. In Mexico it grows from sea level to 1,650 m above sea level.
