Date/Time- 15 Jan 2022
Location- Nipani, north Karnataka.500 ASL
Habitat- Wild in sugarcane field
Plant Habit- Herb 

It’s a juvenile baby plant, more-or-less just a sporeling, so not identifiable until full sized and fertile.  Ferns need adult fronds to be recognisable.
Probably a Thelypteris, perhaps T. (Christella) dentata or something like that. Wait until its an adult.
