Taxonomic Comments
This record is for the broad treatment of Athyrium filix-femina, including A. filix-femina ssp. angustatum and A. filix femina ssp. asplenioides (=A. filix-femina var. angustatum and A. filix-femina var. asplenioides of FNA (1993, vol. 2)), as recognized in Kartesz (1994). Weakley et al. (2025) treat the species more narrowly, excluding both subspecies as the distinct species A. angustatum and A. asplenioides.
