Discussion
Subspecies smallii is widely cultivated and was likely transported extensively by Spanish explorers very early but appears to be native to coastal areas of southern Florida and Matanzas in northern Cuba. Fieldwork suggests that several if not all Florida populations have apparently been extirpated due to development and human activity on Chokoloskee Island in the Florida Keys.
