Angiopteris evecta (G. Forst.) Hoffm, wild fern from Gudalur area of Nilgiris Tamilnadu at an altitude of 1400m
The fern uploaded seems to be Angiopteris evecta
I hope this sp. may be Angiopteris helferiana C.Presl. According to Dr. Chris Fraser-Jenkins Angiopteris evecta (G. Forst.) Hoffm is not found in India. Here is my earlier upload and find World Fern Expert Dr. Chris Fraser-Jenkins’s comment and notes.
Angiopteris helferiana C.Presl is an unresolved name according to plant list. In my earlier paper also it is identified as Angiopteris evecta only
I think it would be better if we concentrate on differences between two species to resolve. A species being listed as unresolved by the Plant List has no meaning. It only shows their limitations, not reflection on status of any species.
In the Nilgiris there are two species (as in most of India), A. helferiana and A. indica – they differ subtly in various ways, but one obvious feature is the distance of the sori from the edge – helferiana has slightly to markedly submarginal sori, and in indica they are always marginal (but beware as an exposed helferiana can have just about marginal sori – but not the other way round). Your photo does not show the diagnostic features of the sori – not knowing what is needed to see. So I can’t tell which one it is from a general habit photo of the whole plant. Both have very short, almost no recurrent false veins coming in from the margin between the veins, only just reaching the inside of the soral line.
