Tectaria incisa is occasionally found growing in swamps and wet hammocks, as well as terrestrial or on limestone outcrops in Miami-Dade, Palm Beach, and Broward Counties. It is apparently a recent introduction from Tropical America (Wunderlin, 2003). This invasive fern can be mistaken for the rare Florida native, broad halberd fern.
