Dear Dr. Santhan,

      You really need to get hold of a modern book on Indian ferns, not 19th Century ones!  Also check the spellings of names properly.  The genus you intended was Lastrea, not Lassea.  But Lastrea is a synonym of Thelypteris and does not apply to the Dryopteridaceous fern, Dryopsis scabrosa - different families.

     I can't see details of the sori in this photo, but I would suggest it looks more like Hypolepis resistens - in Dennstaedtiaceae - which has a long, thin creeping rhizome and fronds arising separately (unlike Dryopsis scabrosa).  But no rhizome has been collected in the specimen.  Does that fit what you remember of it in the field?

   Best wishes,

      Chris Fraser-Jenkins (chriso...@yahoo.co.uk).
