Native to, Venezuela

Known only from the understorey of the montane cloud forest in the north-eastern Coastal Cordillera, state of Sucre, Venezuela; from 730-1250 m. Although the voucher for collection Steyermark 94803 mentions the palm growing at 1600 m on the Cerro Humo, this must be an error because the summit of this mountain has been reported to be 1250 m.

Location: Venezuela (10.686013°N, -62.404404°E)
