Discussion

This species is restricted to the oölitic limestone of the pine rocklands of Dade County (S. Zona 1985). The natural habitat of Sabal miamiensis has been urbanized, so this species is likely extinct. Despite differences in habitat, this species may not be distinct from S. etonia.

Of conservation concern.
