|discussion=<p>In the flora, <i>Asplenium dalhousiae</i> is found only in the Mule, Huachuca, and Baboquivari mountains of southern Arizona. The pattern of disjunction in the worldwide range of this species is highly unusual.</p><!--
--><p><i>Asplenium dalhousiae</i> is sometimes placed in the genus Ceterach on the basis of its thick, pinnatifid leaves. Most pteridologists, however, restrict Ceterach to species with densely scaly, pinnatifid leaves. <i>Asplenium dalhousiae</i> is placed in Ceterachopsis by pteridologists who believe it merits its own genus.</p>
