Note:—Five genera ( Cyclosorus, Macrothelypteris, Phegopteris, Pseudophegopteris, Thelypteris) recognised by Smith (in Kramer & Green 1990) and several formally proposed genera were treated as subgenera in Cyclosorus and Thelypteris . The current understanding of the relationships within the family is limited and thus we employ a conservative approach with large genera concepts for species belonging to Cyclosorus and Thelypteris . Narrower genera concepts are discussed to be replaced these two large genera but the current evidence is insufficient to make final conclusions.
