I was a bit confused so I didnt reply earlier. I was of the notion that Dryopteris should always have kidney shaped sori, on the basis of which I had considered Mr. Tanay's name as incorrect. But then Dr. Jatinder Chadha told me that its not necessary. So we both did some home work and came to the conclusion that the above plant cant be Dryopteris chrysocoma (Christ) C.Chr.. Infact D. chrysocoma does have a kindey shaped sori, but during mature condition the shape may not be clear. Secondly, according to Jenkins (followed by Dr. S.P.Kullar), Indian Dryopteris genus has been grouped into 2 sub genus, 1. DRYOPTERIS and 2. NEPHROCYSTIS. D. chrysocoma belongs to subgenus Dryopteris; Section Pandae, where the pinna margin is supposed to be deeply lobed to the costa, which is not in the present case.
Description of D. chrysocoma also says that the indusium is reniform, persistent and they hardly shrivel. In the present picture the indusium seems to be missing!! and secondly the species is supposed to be distributed from 1700m - 3300m asl so it cant be a common fern distributed in North India. But we cant conclude anything due to insufficient evidence. So we hereby request members who are posting fern pictures, that please do send the pictures of: 1. complete plant 2. one complete frond with the rhizome and stem 3. closeup of one pinna (both surface) 4. Closeup of pinnule (both surface) 5. Closeup of sori. This will greatly help in the identification of the species correctly.
