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.[1] 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.

(=) tribe Loxogrammeae R.M.Tryon & A.F.Tryon 1982
(=) family Loxogrammaceae Ching ex Pic.Serm. 1975
Lacks sclerenchyma (supporting tissue) in plant body, except in the roots.[2]
(=) tribe Drynarieae Subh.Chandra 1982
(=) tribe Selligueeae (author?)[2]
(=) family Drynariaceae Ching 1978
Combines drynarioid and selligueoid ferns
