is it Cyclosorus cyatheoides????

That’s Thelypteris nudata (syn. Pronephrium nudatum) – Cyclosorus is confined to the small T. interrupta group, only one in India.
It is native.


Need species confirmation…

Need species confirmation is this Thelypteris serrata, I have
collected from Narcondam Island, A&N Islands. For identification
please find attached file.

Ah, no, Thelypteris (Meniscium) serrata is a Central American species from Cuba and the Caribbean – nothing to do with Asia.  Wonder how you found that name? – not in any Asian fern books!  One needs to see the well-known literature on Indian ferns, not some random website somewhere with American ferns.
This is almost certainly Thelypteris (Pronephrium) nudata, common throughout India, also Myanmar, Thailand etc. – it pops up in many places and is very common and widespread.  Personally I did not know of it from the Andamans, so I’m afraid I missed A. & N. out from the Annotated Checklist of Indian Pteridophytes vol. 1 (2016).  I haven’t got my copy of Dr. Dixit & Sinha’s Fern Flora of the Andman & Nicobar islands here with me to check if they noticed it, but that work was pretty poor, incomplete and many misidentifications – nevertheless it would be worth checking to see.
I wrote a note in my copy of IC 1, but now the three volumes of the Checklist are all published I won’t be writing on that any time..  If you have more substantial things to say about Andaman ferns, it could be added to paper on your collections and the fern-flora there.
If you could look it up in all the important literature, you could see if anyone mentioned it from there before – and check Kew’s website, and Schaffer-Fehre’s account in Handb. Flora Sri Lanka etc. etc. for range, plus Sledge’s Thelypteridaceae of Ceylon for range.  See if anyone mentioned the Andamans (also Hooker’s Species Filicum (but probably under Neprodium multilineatum there).
