Cryptogrammoideae

Cryptogrammoideae is one of the five subfamilies of the Pteridaceae family of ferns. The subfamily contains three genera and about 23 species. The following diagram shows a likely phylogenic relationship between the three Cryptogrammoideae genera and the other Pteridaceae subfamilies.

Although the Cryptogrammoideae subfamily is similar to the family Cryptogrammaceae proposed by Pichi Sermolli in 1963, that group contained the morphologically similar genus Onychium (now in the Pteridoideae subfamily) instead of the less morphologically similar Coniogramme genus.
