i think nephrolepsis sps
If it assumes tree size, it may be Alsophila sp.
Thank you hari for your suggestion of Nephrolepis. However, I cannot see any that look like it.
I should have mentioned that it was towering above me…
I was actually thinking of Dicranopteris but I think I have seen this in Sikkim. It is much bigger with longer fronds.

Dicranopteris linearis ( Burm.f.) Underw. wild fern from Western Ghats Tamilnadu.
Yes, that’s D. linearis all right, in its established, stabilised sense. The other species present in South India is D. taiwanensis, but that is quite different.
But a nasty little problem arose – the lectotype of D. linearis is unfortunately a Javan specimen, not the Sri Lankan one most people thought. In Java the genus is much more complex and the lectotpye is actually a specimen of the S.E. Asian D. curranii– not noticed by Mazumdar when he contributed the taxonomy to Callmander & Fumeaux’s detailed paper on Burman’s ferns of the Flora Indica (Candollea 2019).
It would be unthinkable to swap over such a widely known name and it needs a proposal in Taxon to conserve the name Polypodium lineare Burm.f. with a new conserved type. That will of course be recommended, but will take time for final decision to be made. In the meantime we should go on calling this plant D. linearis…
