''Cyclosorus'' is a genus of
ferns in the family
Thelypteridaceae, subfamily Thelypteridoideae, in the
Pteridophyte Phylogeny Group classification of 2016 (PPG I).
[ Other sources sink ''Cyclosorus'' into a very broadly defined genus '' Thelypteris'',][ 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.][

The genus is named from the Greek, referring to the circular sori.][Les Robinson - Field Guide to the Native Plants of Sydney, page 320]
