3-34 genera (depending on genus concept), 1100-1200 spp. The genus concepts were wildly fluctuating and disputed, from the inclusion of everything into one monster genus Thelypteris to the split of over 30 genera. We use the new genus concept by Fawcett & Smith (2021), which is based on molecular results and adopts a compromise approachl
