Please identify this plant from a sacred grove of Kannur, Kerala. Isn’t it an angiosperm?

There is no close-up showing the rhizome – so it can’t be seen properly.  But I assume it is Vittaria (Haplopteris) elongata (a pteridophyte) – which should have brown sori at the edge.  Soak it out in a bucket of water for 24 hours, as Vittaria’s can’t be identified when all rolled up [“Vittaria rolypolyana” ined.!], then press it with some rhizome, and photograph it again, closer-up.
