This is another sp. from Darjeeling. Need your help for proper ID


Beautiful capture!


Spectacularly beautiful photo – makes me feel I’m up in the hills among the cool rain and ferns (disregarding the leeches!) while sitting at my desk in Kathmandu!  It is Glechenia gigantea – alternative, if one likes to split the genera – hardly necessary, but tolerable

A very old scanned picture of mine taken in Darjeeling.

These ferns leaves were very long, almost two feet in length.
Hoping to get the id

They were very common by the roadside.


Diplopterygium judging by the large size, habitat, and by the two large bippinnate pinnae and apical resting bud


its G.gigantenum


This big fern is Gleichenia gigantea – some people prefer to separate it into a genus Diplopterygium, as Diplopterygium giganteum. I’m not entirely sure which genus I prefer…

Diplopterygium longissimum (Blume) Nakai : 7 posts by 3 authors. Attachments (3)

Diplopterygium longissimum (Blume) Nakai (=Dicranopteris longissima (Blume) Nakai) frequently growing fern in dense patches, from Darjeeling area.


No, I’m sorry to mention this, but before answering, you really need to be familiar with modern literature on Indian ferns, otherwise it just confuses everybody. D. longissimum does not occur in or near India.

The common Indian species (Darjeeling etc.) is Diplopterygium giganteum.

Ferns ! ID ??

Young, uncurling fronds of the main, common Indian species of Diplopterygium, D. giganteum  (often misreported as G. longifolium etc. since Panigrahi’s time, under Gleichenia). It is a beautiful sight around Darjeeling and I’ve also photo’d stands of it beside the roads there and in East Bhutan. It doesn’t extend west of Nepal.

Diplopterygium giganteum – with a skipper butterfly.

But I think it would be a good idea to see the scales on the uncurling frond-apex, just to be quite sure it isn’t D. blotianum.  However I don’t have any reason to think it is that.

Perhaps Cyclosorus aridus


I think it is not matching.


The photos from Surjebhinayak (Bhaktapur Distr.) are mixed – the close-ups are Diplopterygium giganteum and there’s a bit of it near the top of the first photo. But in the first photo there are also other ferns – but not clear. Probably there is also a Polystichum, or an Athyrium or Microlepia strigosa – they can’t be seen properly.

Is this the fern-photo group that … thought was Thelypteris arida?  My laptop has gone a bit funny and I can’t get the whole screen until I get someone to restore it (I just got back from India), so not sure if I have seen the “T. arida” photo or not.


Yes the habitat image has two species intermingled.
As such I have shot close-ups of individual sp.
separately and posted accordingly.
All mages (close-ups) besides the habitat one (First image) are
from the same plant. I guess the Id is Diplopterygium giganteum
as suggested by you. Please validate !
