Pteridoideae is one of the five subfamilies of the fern family Pteridaceae.

[2] The following diagram shows a likely phylogenic relationship between Pteridoideae and the other the Pteridaceae subfamilies.

Ceratopteridoideae) Pteridoideae Cheilanthoideae Vittarioideae 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.

[4] Pteris Actiniopteris Onychium Gastoniella Cerosora Pityrogramma Cosentinia Anogramma Jamesonia Pterozonium Tryonia Taenitis Syngramma Austrogramme The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized 13 genera.

[5] Shortly afterwards, the genus Gastoniella was created for three species formerly placed in Anogramma which a molecular phylogenetic analysis had shown to be distinct.
