Pteridoideae

Pteridoideae is one of the five subfamilies of the fern family Pteridaceae. This subfamily contains about 14 genera[1] and around 400 species.[2]

Taxonomy

Phylogeny

The following diagram shows a likely phylogenic relationship between Pteridoideae and the other the Pteridaceae subfamilies.[3]

Pteridaceae

Cryptogrammoideae

Parkerioideae (syn. 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. 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.[4]

Genera

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.[4]
