Discusión taxonómica
Woodsia mexicana is thought to be derived from past hybridization between W. phillipsii and W. plummerae. The plants are relatively small but have large segments/lobes, pale stipes, and are heavily glandular. Some teeth have crustose projections, and the indusial segments are united proximally, filamentous distally. The species has a distinct range and little overlap with its presumed parents.A
