'''''Pteridoideae''''' is one of the five subfamilies of the fern family Pteridaceae. This subfamily contains about 14 genera<ref name=Christenhusz-2011/> and around 400 species.<ref name=Schuettpelz-2007/>
==Taxonomy== ===Phylogeny=== The following diagram shows a likely phylogenic relationship between Pteridoideae and the other the Pteridaceae subfamilies.<ref name=Schuettpelz-2008/> {{clade|style=font-size:90%;line-height:100% |label1 = '''Pteridaceae''' |1={{clade |1=Cryptogrammoideae |2={{clade |1={{clade |1=Parkerioideae (syn.

The cladogram below shows one hypothesis for the evolutionary relationships among the genera of the Pteridoideae, based on a maximum likelihood analysis using six plastid markers. The authors of the study identified four major clades. The ''Pteris'' and JAPSTT clades are found worldwide; the GAPCC clade is pantropical; and the ''Actiniopteris''+''Onychium'' clade is restricted to the Old World.<ref name=ZhanZhouLuZhan17/> {{clade|style=font-size:90%;line-height:100% |label1=Pteridoideae |1={{clade |label1=''Pteris'' clade |1=''Pteris'' |2={{clade |label1=''Actiniopteris''+''Onychium'' clade |1={{clade |1=''Actiniopteris'' |2=''Onychium'' }} |2={{clade |label1=GAPCC clade |1={{clade |1={{clade |1=''Gastoniella'' |2={{clade |1=''Cerosora'' |2=''Pityrogramma'' }} }} |2={{clade |1=''Cosentinia'' |2=''Anogramma'' }} }} |label2=JAPSTT clade |2={{clade |1=''Jamesonia'' |2={{clade |1=''Pterozonium'' |2={{clade |1=''Tryonia'' |2={{clade |1=''Taenitis'' |2={{clade |1=''Syngramma'' |2=''Austrogramme'' }} }} }} }} }} }} }} }} }}
===Genera=== The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized 13 genera.<ref name=PPGI/> Shortly afterwards, the genus ''Gastoniella'' was created for three species formerly placed in ''Anogramma'' which a molecular phylogenetic analysis had shown to be distinct.<ref name=ZhanZhouLuZhan17/> {{Div col|colwidth=20em}} * ''Actiniopteris'' <small>Link</small> * ''Anogramma'' <small>Link</small> * ''Austrogramme'' <small>E.Fourn.</small> * ''Cerosora'' <small>Domin</small> * ''Cosentinia'' <small>Tod.</small> * ''Gastoniella'' <small>Li Bing Zhang & Liang Zhang</small> * ''Jamesonia'' <small>Hook. & Grev.</small> * ''Onychium'' <small>Kaulf.</small> * ''Pityrogramma'' <small>Link</small> * ''Pteris'' <small>L.</small> * ''Pterozonium'' <small>Fée</small> * ''Syngramma'' <small>J.Sm.</small> * ''Taenitis'' <small>Willd. ex Schkuhr</small> * ''Tryonia'' <small>Schuettp.</small> {{Div col end}}
