281011-MS – 63- Fern ID requested: Please identify the fern, which is wild and seen all around the area near Abbi Falls, Coorg. Photos taken on 23.10.11.
Looks like a Diplopterygium.
No it is not Diplopterygium/Gleichenia – that is quite different and also not present in South India.
This is Pteridium revolutum (Blume) Nakai, which occurs commonly almost throughout India. You will find it referred to as P. aquilinum sometimes, especially in 19th Century literature, or in works that are not aware of modern fern taxonomy – but that species is European and African, and not present in India.
Could be Hypolepis resistens. If there had been a closeup of the lower surface of the leaf, one could say something with certainty
Please look at it more carefully – it is quite clearly and definitely the Pteridium, as I said. Hypolepis is far more finely dissect – the third photo magnifies quite well and shows without any doubt at all that it is Pteridium revolutum. This does not need to be confused any further.
WELL YOU ARE CORRECT … my only objection is THAT IF THE FERTILE PORTION HAD BEEN PHOTOGRAPHED! ONE COULD BE CERTAIN
Ah yes, that’s definitely right – I agree it wasn’t a very informative photo in many respects!
Kas Week: PKA12— Fern from Kas: Came across this plant near kas Lake, Satara.
This is Pteridium revolutum, the S. Asian Bracken, a poisonous fern (though not as poisonous as Thelypteris arida!).
