The ( Asplenium pinnatifidum ) is a small, evergreen fern that primarily inhabits the crevices of non-calcareous rocks, such as sandstone and shale, across the Appalachian Mountains and into the Midwest. Often overlooked by casual hikers, this rare plant is a fascinating example of evolutionary biology in action, representing a stable, fertile hybrid species. A Hybrid Origin
