Rhachidosorus Ching 1964

  • R. mesosorus (Mak.) Ching 1964

Rhachidosoraceae is a family of ferns in the order Polypodiales.[1] Its only genus is Rhachidosorus, which was described by Ren Chang Ching in 1964, with about 7 species in eastern and southeastern Asia, including Japan, the Philippines, and Sumatra.[2]


The species of Rhachidosorus, all published, with the genus name, by Ching in Acta Phytotaxonomica Sinica volume 9, number 1 include:[3]

(=) Diplazium mesosorum (Makino) Koidz. 1924
(=) Athyrium mesosorum (Makino) Makino 1899
(=) Asplenium mesosorum Makino 1898
(=) Athyrium fragile Tardieu 1932 (nom. illeg. hom.)
(=) Diplazium chrysocarpum Alderw. 1914
(=) Athyrium stramineum Copel. 1908
(=) Diplazium pulchrum Tagawa 1935

Phylogenic relationships[edit]

The following diagram for the eupolypods II, based on Lehtonen, 2011,[4] and Rothfels & al., 2012,[5] shows a likely phylogenic relationship between the Rhachidosoraceae and the other families of the eupolypods II clade.
