This is Thelypteris (Section Menisciopsis) penangiana, common mid-altitude species. See illustration in Khullar – should be in your University libaray.

Curiousy it does not occur in Penang, Malaya – it was named from Indian material sent in witha mistaken locality of Penang! Like Lathyrus japonicus from Britain which was never seen in Japan.
