Fraser-Jenkins (Taxon. Revis. Indian Subcontinental Pteridophytes, 101. 2008) regarded Pteris confertinervia as a synonym of P. cretica var. cretica. Reviewer Ralf Knapp indicates that there is a need to reinvestigate the identity of the plants commonly identified in Taiwan as P. cretica subsp. cretica.
