Asplenium × wherryi
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.
In theory, A. × wherryi might be found anywhere the ranges of its parental species overlap, stretching down the Appalachian Mountains from New York to Georgia and in the Shawnee Hills of Indiana and Kentucky. In practice, it is quite uncommon and scattered. It has been reported from New Jersey, Lancaster County, Pennsylvania, Virginia, Kentucky, and Whitfield County, Georgia. The Pennsylvania report consisted of a single plant which grew for a few years at Tucquan Glen. The type locality in New Jersey was reported destroyed in 1956, although A. bradleyi was rediscovered there in 1960.
