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 Distinguishing it from its parents requires a close

: Its fronds narrow into a long, slender point, a trait inherited from the Walking Fern.

Because it possesses a double set of chromosomes from both parents, it can reproduce on its own and is considered a true, distinct species rather than just a one-off cross. Identification Features It has also been documented in: Asplenium -

: It typically grows in small, dense clusters directly out of cracks in shaded, damp rock faces. Where to Find It
