Discusión taxonómica
Woodsia cochisensis is distinct by being sparsely to moderately glandular and has thickened lustrous blade margins with some short-crustose projections on the teeth. It differs from W. phillipsii and W. neomexicana by having indusial segments broad and being non-filamentous at bases. Woodsia cochisensis is less glandular than W. mexicana and crosses with W. phillipsii to give intermediate triploids in Arizona, Sonora, Coahuila, San Luis Potosí, and perhaps Chihuahua.A
