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
Unlike many hybrids that are sterile, Asplenium pinnatifidum is a fertile . It originated from a natural cross between two other ferns: asplenium pinnatifidum
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 Because it possesses a double set of chromosomes
( Asplenium rhizophyllum ): Contributes the long, tapering frond tips. Often overlooked by casual hikers, this rare plant
: Unlike the Walking Fern, which has smooth-edged (entire) leaves, the Lobed Spleenwort has distinct lobes along the entire length of its frond.
