General Comments:

This plant is believed to be extirpated in the wild in Florida.  According to most sources, it was known from a single area south of Miami near Biscayne Bay.  Old specimens at the University of Florida Herbarium for Escambia and Okaloosa counties were re-examined in 2006 and re-identified as Baccacharis dioica.  It has also been reported to have been found on a dune near Mobile, AL (Woodlanders, Inc.) and introduced into the nursery trade from there.  The map of herbarium speciment locations on the Florida Plant Atlas have not been updated. 

Plants commercially available in FL apparently come from imports from the Bahamas.
