|discussion=<p><i>Asplenium bradleyi</i> is a morphologically variable species, the allotetraploid derivative of <i>A. montanum</i> × platyneuron (W. H. Wagner Jr. 1954; D. M. Smith and D. A. Levin 1963; C. R. Werth et al. 1985). The sterile diploid form of <i>A. bradleyi</i> has been collected twice in nature (W. H. Wagner Jr. et al. 1973; A. M. Evans 1988), and isozyme studies indicate that the allotetraploid has had a polytopic origin (C. R. Werth et al. 1985b). Occurring rarely to locally in the Appalachian region, <i>A. bradleyi</i> overlaps with both progenitor taxa, but it is fairly frequent in the Ozark and Ouachita region where <i>A. montanum</i> is absent. Sterile hybrids with <i>A. pinnatifidum</i> (A. × gravesii), <i>A. montanum</i> (A. × wherryi D. M. Smith et al.), and <i>A. platyneuron</i> are known from nature.</p>
