Family Polypodiaceae

Recent molecular phylogenic analysis has lead to the divison of the Polypodiaceae into five subfamiles, and to the inclusion of genera that have at various times been placed in other families, including the Drynariaceae, Grammitidaceae, Gymnogrammitidaceae, Loxogrammaceae, Platyceriaceae, and Pleurisoriopsidaceae. In the list that follows, the taxa shown with the " (=) " prefix are considered to be synononyms for the accepted subfamily name that they follow. However, this does not necessarily imply that the subfamily contains all of the synonym's previous genera.
