Rhachidosorus is a genus of ferns in the order Polypodiales. [2] It is the only genus in the family Rhachidosoraceae in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). [3] Alternatively, the genus may be placed in the subfamily Rhachidosoroideae of a more broadly defined family Aspleniaceae, [1] the family placement used in Plants of the World Online as of November 2019.
