The origin and phylogenetic affinities of the tetraploid Woodsia plummerae have not been established with certainty. The hypothesis that it arose as a hybrid between the Mexican species W. mollis (Kaulfuss) J. Smith and W. mexicana Fée (D. F. M. Brown 1964; D. B. Lellinger 1985) seems untenable in light of recent chromosome studies indicating that the latter species is also tetraploid (M. D. Windham 1993). On the basis of sporophyte morphology and spore ornamentation, W. plummerae appears most closely related to the W. mexicana complex and W. oregana. In fact, W. oregana can be difficult to separate from W. plummerae in western New Mexico and northern Arizona. Intermediate plants occurring in this region may represent stable allotetraploids resulting from hybridization between the diploid progenitors of W. plummerae and W. oregana subsp. cathcartiana. Considering the available evidence, populations of W. plummerae in the United States probably originated through autopolyploidy from a recently discovered, but as yet unnamed, Mexican diploid of similar morphology. Woodsia plummerae occasionally hybridizes with W. phillipsii to produce sterile, morphologically intermediate triploids.
