Discussion

Lythrum flagellare is relatively rare. A collection from Hernando County is possibly a hybrid of L. alatum and L. flagellare, as suggested by a more robust habit, leaves ultimately crowded and alternate on the stems, and less slender, more cylindrical floral tube than is typical for L. flagellare.
