Florida Keys History and Distribution:
Reported in 1913
by John Kunkel Small for pinelands and coastal dunes from the upper Keys to the lower Keys. Kruer (1992) reported this for the lower sandy Keys, but we have been unable to verify this report. Although weedy, we treat as native and extant from the upper Keys to the lower Keys.
