Discussion

Jatropha curcas now has a circumtropical distribution but probably originated in Central America; it is naturalized in southern Florida. The latex of J. curcas is used for soap making and for medicinal purposes; the seeds are used for biofuel production.

The geographical origin of Jatropha multifida cannot be determined with certainty; it is probably native to the West Indies. The species is widely cultivated throughout the tropics as an ornamental and has escaped and naturalized in many areas, including central and southern Florida.
