This is Thelypteris (Sect. Cyclosorus) interrupta, a low-altitude marsh fern, occurring from Nepal and Bihar eastwards, and in peninsular India, including the South – it is a S.E. Asian (Malesian) element in India.
This is Cyclosorus interruptus
I wonder if … or anyone could outline the morphological distinction between Cyclosorus and Thelypteris as genera? It seems to me the differences are minute and not practicably separable at the level of genus. Cutting up the molecular “tree” is actually an arbitrary process, and should depend also on morphological characters.
