A reply: "Ah yes, that's better - I can see immediately now the inframarginal sori - it is Angiopteris helferiana (please bear in mind that A. evecta is not even within 5000 miles of India!) - the commonest Angiopteris in India. It is not a threatened or rare fern in India, nor vulnerable, but occurs in thousands of localities wherever there is forest and streams. I have myself found it in many places in Assam state, though I agree ferns in general are being cut and burnt down enormously in Assam along with all the forested areas. But it can't qualify as under threat in Assam, as it often grows in damp, overgrown ditches in many localities - in fact I seldom don't find it whenever I look in ferny places in Assam. However there are some other regions in India where it is locally threatened as one approaches drier regions (where a lot more forest is under threat). I forget now how far west it goes - and would have to check my lists on www.groups.yahoo.com/group/Indian-Ferns (sign in as a new member and then go to files on the left - and see the paper on Nepal ferns and Indo-Himalayan lists) - but do I remember rightly, I think, seeing it as a rarity in the West Indo-Himalaya in Pithoragarh (at Debichhina)? - that's because it is right on the edge of its climatic range there. Further west, lower-altitude localities get far too dry during the non-monsoon time in Winter. A. helferiana is also common in forested areas of South India. For information on India's threatened pteridophytes, I recently published a full assessment in the Bull. Tokyo Sci. Mus. (2011), giving IUCN categories (which have to apply nationally, not regionally within a country). Many species have erroneously been described as threatened in order to get a paper to have more impact, when they are not! Best wishes, Chris F.-J."
