Ceratopteridaceae is the family name for the clade that is now known to include the two genera Ceratopteris and Acrostichum.
Although Ceratopteris was long isolated under its own family, due to adaptations for a dedicated aquatic existence, recent genetic study has determined that these two genera are allied.
The former plant family name "Parkeriaceae" is no longer allowed in botanical nomenclature, due to the rule that higher taxa in plants must reflect their type division (in this case, genus).
Christenhusz et al., 2011, inluded these two genera alone in the subfamily Ceratopteridoideae in their larger treatment of the Pteridaceae family in the order Polypodiales.[1]
