Florida Keys History and Distribution: Reported in 1913 by John Kunkel Small for hammocks, pinelands and disturbed areas from the upper Keys to the lower Keys.  Not observed in the lower sandy Keys until 1980 (Reimus & Robertson, 1997).  Although weedy, we consider this native and extant throughout the Florida Keys.
