Discusión taxonómica
The most similar Mexican species are A. solmsii and A. insolitum, from which A. breedlovei differs in having creeping rhizomes. The nearest affinities of A. breedlovei are obscure; it seems to be a rather isolated species, and is unusual in the genus because of the creeping rhizomes. It does not appear closely related to sect. Hymenasplenium, species of which regularly have creeping rhizomes.A
