A reply: "I wonder if Dr. Vijaydas 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. But the taxonomic and cladonomic decisions also need to consider the extensive and strong similarities between all five American-led "genera" within Thelypteris, which all show the same and easily recognisable pattern - all obvious Thelypteris. The fact that, molecularly, both free-veined and anastomosing-veined groups of species are consigned to "Cyclosorus" really makes the distinctions minute and insignificant and Cyclosorus almost indefinable except, perhaps by a microcharacter. I prefer to go along with what Holttum said - that the only practical or sensible alternative to splitting (into his far too many genera, now no longer recognised world-wide, but good as natural sections), would be to reunite them all into the single genus, Thelypteris. Cheers, Chris. "
