General Comments:This plant is believed to be extirpated in the wild in Florida.  In Florida, it was known from a single area south of Miami near Biscayne Bay.  It has also been reported from a dune near Mobile, AL.  Recent appearance in the nursery trade apparently comes from imports from the Bahamas.
