Phylogenic relationships
The following phylogram, shows a likely relationship between Cheilanthoideae and the other Pteridaceae subfamilies.[2]

}}Although Cheilanthoideae subfamily itself is thought to be monophyletic, at least half of its genera (including Cheilanthes, Doryopteris, Notholaena, and Pellaea) have been shown to be polyphyletic.[3]
