Discusión taxonómica
Specimens cited as this species from Chihuahua by Knobloch and Correll (1962) are A. gentryi (e.g., Correll & Gentry 23032; Gentry 8064). Also, inclusion of Chihuahua and Sonora in the range of A. resiliens by Mickel and Beitel (1988) and by Mickel (1992) was based in part on misidentified specimens, but A. resiliens does occur in both states. Asplenium resiliens appears to be most common in northeastern Mexico, in the states of Nuevo León and Coahuila.
Asplenium resiliens is closely related to A. monanthes, but is distinguished from that, as well as other dark-stiped Aspleniums (except A. heterochroum and A. palmeri), by the lack of conspicuous hydathodes adaxially. It is distinguishable from A. heterochroum by the thicker and more deflexed pinnae, forked fertile veins, and occurrence at higher elevations (usually above 1400 m in A. resiliens). Asplenium resiliens differs from A. palmeri in having nonproliferous blade apices, proximal pinnae deflexed, subentire to weakly crenulate pinna margins, and longer stipes. A few mixed collections with other species in the group have been seen, e.g., Copeland herb. 67, UC, from Morelos, which also contains a frond of A. hallbergii.
