some sort of bird’s nest fern???? have seen any really big “Mature ” plants in those locales??

---

This plant is too young to decide.

---

The plant is too young. May be Microsorum sp of Polypodiaceae.

---

Unfortunately the photo does not really show enough, as one needs to see the pattern of the sori underneath. But is appears to be a Microsorum [note the spelling – no ‘i’], and I would guess probably M. zippelii.

---

Yes, that’s definitely true – but most likely Microsorum zippelii – need to see the sori.

---

This type of a picture of a fern is useless for any type of taxonomic work. In future you should at least take a picture of the fertile portion or the backside of the fern frond. A close up of the rachis and stipe showing the scales etc. Such a picture can help in the identification. Other wise it is only useless guess work which is of no consequence.

---

Drynaria sps. , possibly D.quercifolia.

---

Well yes, I must agree with Prof. …, too – so often we all get sent photos which do not show the things one needs to see, which differ from genus to genus, so one is left struggling to catch the general “look” of the plant, drawing on one’s field-experience. Still let us check if my guess at M. zippelii is entirely useless or not – can we have a photo of the sori on the underside, please?
I’m perfectly ready to eat my hat if wrong, but to me it looks most likely to be that. In my reasoning was that the wide-fronded Lepisorus (L. scolopendrium group) are not present in South India, nor is Microsorum membranaceum. Thus I think M. zippelii is most probable. But I agree accidental and guess taxonomy are far from ideal!
