''. In 2006, Smith ''et al.'' included Cryptogrammaceae as part of the family Pteridaceae, and in 2011, Christenhusz ''et al.'' listed its three genera in Cryptogrammoideae, one of five subfamilies of Pteridaceae, a placement used in PPG I. The following diagram shows a likely phylogenic relationship between the three Cryptogrammoideae genera and the other Pteridaceae subfamilies.
