Abstract
Following a recent phylogenetic study, we here review the circumscription of the grammitid fern genus Oreogrammitis (Polypodiaceae: Grammitidoideae). We propose three new genera Calligrammitis, Devolia, and Glabrigrammitis, to accommodate the three clades resolved outside of the core Oreogrammitis. The taxonomic treatment is presented, and the morphology of each new genus is shown with a color plate.
