(Small, 1928; Austin et al., 1980; Jones, 1983). Also present in the Yucatan Peninsula and Gulf Coastal Mexico, Belize, and Honduras. Indigenous populations also exist in the Cayman Islands. This species appears to be the palm found by Gillis et a1. (1975) in the Bahamas. This taxon is very commonly cultivated throughout the tropics and subtropics and apparently naturalizes with ease.
