For ID070609ET – indiantreepix | Google Groups: 2 images.
This plant interested me because of the uniqueness.
I took this plant picture while trekking from 2100 metre level to
2800 metre level at Great Himalayan National Park on May 12, 2009.
Kindly give ID


Appears to be some Fern species.


It is indeed a fern species. The 1st pict shows the circinate vernation, which is peculiar to the ferns.


Yes this is of course a fern species! Please someone mention the Species! Because, it’s occurrence was at 2100 metre level to 2800 metre level at Great Himalayan National Park.
and I was also observed in the Melghat Tiger Reserve, Satpuda range in central India. That’s why want to know the Species of given Genus Nephrolepis!


i know it under the name Wurmfarn. Wurm because of the form of the “leaf” This Wurm opens to a leaf. Very common in germany too.  See the following Info. Sorry it is in german.
Well i am not so sure about it being any particular genus as i have seen same kind of species (which is still unidentified) during the visits to Darjeeling and surrounding environs(reference here being the higher altitude). Also, to determine the fern species one needs to see the morphology of fronds (ie leaves) as well the sori (reproductive structure), which is not at all clear in the given pictures!
Of course, the resemblance is more closer to the Dryopteris, as given by …, as it is known as the ‘Wood Ferns’ which tend to grow on the ground in wooded places.
This link gives a little more insight to what we are looking for
Check this link as well

offcourse this is a fern species, but I never found this in Melghat Tiger Reserve, Central India, as stated by Mr. Thakre. Its a large one, there are other two most commonly found fern species in Melghat, which I am sending for ID separately.


It is neither Nephrolepis nor Dryopteris, but belongs to either Thelypteridaceae or Athyriaceae,  have to find out.
Have any chance to take some close fotos of this ? showing the following –
Soral arrangement, lamina, pinnae (leaflet), stipe


Attaching a close up sent by … in a separate mail.


I replyed to the author of this plant regarding some more clips to show soral arrangement and pinnae and pinnule and eventually I can identify.


It is Dryopteris wallichiana var wallichiana.
Before I replied it as not Dryopteris but that was my mistake, sorry for that.
