Phylogeny The following diagram shows a likely phylogenic relationship between Pteridoideae and the other the Pteridaceae subfamilies. }} 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. }}
Genera The
Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized 13 genera. Shortly afterwards, the genus
Gastoniella was created for three species formerly placed in
Anogramma which a
molecular phylogenetic analysis had shown to be distinct. •
