Cyclosorus is a genus of four species of ferns.[1][2][3] in the family Thelypteridaceae; Cyclosorus interruptus, Cyclosorus lenormandii, Cyclosorus sandwicensis, and Cyclosorus striatus.

There has been much taxonomic debate with this group. Zipcode Zoo quotes 448 species in this genus[4] while Tropicos gives 470 names, including Cyclosorus elegans.

There are also fossil species known from the Eocene of South China[5] and the Quaternary of Australia.

The genus is named from the Greek, referring to the circular sori.[6]
