No - not P. chrysophylla ( see page 272-273 of the Annotated Checklist of Indian Pteridophytes vol. 1. 2016).  I can't see the colour terribly well, but I think it is yellowish, isn't it?  Trouble is that in the effort to preserve specimens from being eaten in Indian herbaria, they are all dipped in alcohol with mercuric chloride - the alcohol washes most of the farina and its flavinoides off.  Or heat-dried - which makes it melt and stick to the paper - so removed.

But this is P. austroamericana - an adventive species from S. America, very common in South India, but does not seem to reach the north as far as I know.
