Cyclosorus Thailandicus
''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. There are also fossil species known from the Eocene of South China and the Quaternary of Australia. The genus is named from the Greek, referring to the circular sori.Les Robinson - Field Guide to the Native Plants of Sydney, page 320 Species , the ''Checklist of Ferns and Lycophytes of the World'' accepted the following extant species, although noting that only two to four probably belonged in the genus '' sensu stricto'', the rest needing in future to be distributed among other genera. *'' Cyclosorus angustipinnatus'' C.Chr. & Tardieu ex Tard ...

Cyclosorus Interruptus
''Cyclosorus interruptus'', the Hottentot fern or swamp shield-fern, is a fern in the family Thelypteridaceae. It is native to the tropics and subtropics in many parts of the world. In the New World, it is found from Mexico to Argentina, and in the Antilles. In the Old World, it is found in India, China, Malaysia, Sri Lanka and South Africa. It is also found in Australia, New Zealand, Hawaii and other islands in the Pacific Ocean. The various populations differ with respect to genetic cytotypes, glands, pubescence, and frond size. Its habitat is the vicinity of freshwater swamps and it may reach in height. History In 1770 during the first voyage of James Cook, it was collected by Joseph Banks and Daniel Solander not far from Botany Bay. Despite urbanization, it still occurs in a park in the Sydney bayside suburb of Monterey. The specific epithet ''interruptus'' is from the Latin, and refers to the sori.Les Robinson - Field Guide to the Native Plants of Sydney, page 320 The ...
