チャセンシダ属

Also known as hart's tongue fern, hart's tongue, spleenwort, spleenworts, hart's-tongue fern

Asplenium is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider Hymenasplenium separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is Asplenium marinum.
