**
<p>After the original publication by <strong>Wherry</strong> (1925), this taxon has often been treated as a sterile hybrid resulting from the cross of <em><strong>Asplenium montanum</strong></em> and <em><strong>A. pinnatifidum</strong></em>. In a departure from this tradition, <strong>Weakley</strong> (2022) treated <em><strong>A. trudellii</strong></em> as a species based on the sometimes occurrence without the prescence of both parents and often being more numerous at various locations than other sterile hybrid ferns typically exist. We do not believe enough evidence yet exists to drop the hybrid status.-<em><strong>-B.R. Keener</strong></em></p>
