Pteris venusta Kunze , Bot. Zeitung (Berlin) 6: 195-196 195 1848.;
PLEASE ID FERN: THIS IS AN UNDERGROWTH IN EVERGREEN FOREST.PHOTO AT SAWANTWADI IN DECEMBER.
It looks like Asplenium nidus
Looks like a juvenile plant of the Pteris cretica group.
A. nidus is not present in South India, from where it has been widely misreported in error for A. phyllitidis. But both those species have large, simple fronds. This plant in your photo has a palmately dissect frond.
It’s actually P. venusta Kunze, a semi-cryptic S. Indian cytotype of P. pellucida, entire margins.
It is Pteris sp. Not Asplenium nidus. May be a better ID will be possible with a mature plant and bothside pic.
