Species 12 (2 in the flora): native to Asia, Pacific Islands, Australia.
Caryota, readily distinguished by its 2-pinnate leaves, is native to India, southeastern Asia, Malesia, the Philippines, the Solomon Islands, Vanuatu, and Australia. Two species of Caryota are commonly cultivated in southern Florida: C. urens and C. mitis. Both species have naturalized in Dade County, Florida.
