Asplenium pinnatifidum commonly known as the lobed spleenwort or pinnatifid spleenwort is a small fern found principally in the Appalachian Mountains and the Shawnee Hills growing in rock crevices in moderately acid to subacid strata. Originally identified as a variety of walking fern (Asplenium rhizophyllum) it was classified as a separate species by Thomas Nuttall in 1818.
