Cyclosorus is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] Other sources sink Cyclosorus into a very broadly defined genus Thelypteris,[2] or expand the genus to include other genera which PPG I keeps separate. Thus the online Flora of China suggests there are about 250 species compared to the two species suggested in PPG I.[3][1]
There are also fossil species known from the Eocene of South China[4] and the Quaternary of Australia.
The genus is named from the Greek, referring to the circular sori.[5]
