Asplenium × wherryi known as Wherry’s spleenwort is a rare hybrid fern of the Appalachian Mountains. The sterile triploid offspring of mountain spleenwort (A. montanum) and Bradley’s spleenwort (A. bradleyi) it is known from a few sites where those species grow together. First collected by Edgar T. Wherry in 1935 it was largely ignored until a new colony was found in 1961 and the species was named in his honor.
