Cyclosorus  

Cyclosorus is a genus of the marsh fern family Thelypteridaceae, and is native to Western Australia.The genus is referred to as "marsh" ferns to describe their desired wet or inundated habitats. Australia has only one native Cyclosorus specie, Cyclosorus interruptus. 

Cyclosorus is a terrestrial fern growing in swamps or on creek banks, where it may be partially inundated (Bennett, n/d). The plant is commonly found in wetlands and damp areas, however, may also extend into semi-terrestrial areas (Irudayaraj, 2013).
