\n281011-MS – 63- Fern ID requested:<\/a>
\nPlease identify the fern, which is wild and seen all around the area near Abbi Falls, Coorg.<\/span> Photos taken on 23.10.11.<\/p>\n

\n

Looks like a Diplopterygium<\/i>.<\/p>\n

\n

No it is not Diplopterygium\/Gleichenia<\/i> – that is quite different and also not present in South India.<\/p>\n

\n

This is Pteridium revolutum<\/i> (Blume) Nakai, which occurs commonly almost throughout India. You will find it referred to as P. aquilinum<\/i> 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.
\n<\/span> Both species are well known to be toxic to cattle, humans etc. and a lot has been published on the effects of the named alkaloids present – e.g. bovine Haematonurea and cancers etc.<\/span><\/p>\n

\n

Could be Hypolepis resistens<\/i>. If there had been a closeup of the lower surface of the leaf, one could say something with certainty<\/p>\n

\n

Please look at it more carefully – it is quite clearly and definitely the Pteridium<\/i>, as I said. Hypolepis<\/i> is far more finely dissect – the third photo magnifies quite well and shows without any doubt at all that it is Pteridium revolutum.<\/i> This does not need to be confused any further.<\/p>\n

\n

WELL YOU ARE CORRECT … my only objection is THAT IF THE FERTILE PORTION HAD BEEN PHOTOGRAPHED! ONE COULD BE CERTAIN<\/p>\n

\n

Ah yes, that’s definitely right – I agree it wasn’t a very informative photo in many respects!<\/p>\n

\n

This is Pteridium revolutum<\/i>, the S. Asian Bracken<\/b>, a poisonous fern (though not as poisonous as Thelypteris arida<\/i>!).<\/span><\/p>\n

\n

Can you send fotos of this showing under suface of leaf and close pictures, sothat I can Identify, because Pteridium, hypolepis ,Histiopteris\u00a0 etc have this same posture.<\/p><\/div>\n

But tendatively I think it may be Pteridium aquilinum<\/em>, not sure<\/div>\n
