Kindly id. the fern may be Pteris vitata There are two simply pinnate species in the photo - the one with the narrow pinnae is Pteris vittata subsp. emodi, which occurs from lower altitude up to mid altitude and occurs throughout the Himalayan region, and in China, but not in C. and S. India (where only subsp. vittata occurs - both are common in the Indo-Himalayan region). The one with the broad pinnae is Thelypteris (sect. Cyclosorus, subsect. Pronephrium) nudata - another lower-mid altitude species.
Pteris vittata ABJUL01/01 : 2 posts by 1 author. 5 images. I photographed this fern first on May 15 when it was still uncurling and looked very appealing with its geometrical forms. I waited for the sori to develop and photographed it again yesterday. Unfortunately, it was on a slope by the road verge and I couldn’t reach the base to show the stipe and smaller pair of pinnae ascending from below. But the accompanying pictures strongly pointed it to be Pteris vittata. Please correct me if I am wrong. With this I have recorded four species of Pteris here including P. aspericaulis, P. cretica and P. terminalis.
