Dear Dr. Sourav Mahmud,
Yes, I do understand it can be difficult to reach tree-fern fronds. I've
often stood at tip-toe on a steep slope attempting to hook down the tip of
a frond with a stick to pull it slightly down to grab a few pinnules from
the main pinna. Or sometimes throwing a stick or stone up to try to knock
off a pinnule - which invariably falls out of reach into a deep ravine or
something! But without this tree-ferns are just tree-ferns, no
identification possible.
Well the new photo shows the stipes are not dark or blackish, so that
eliminates C. gigantea, C. khasiana, C. henryi and C. andersonii. But I
can't see if they have short spines or not - if so, at that altitude and
place it would be C. spinulosa, as expected. If not, probably C.
brunoniana (nom. cons. prop.) (syn. C. sollyana) - but the pinnae are not
in enough detail to see that.
So for now I stick with probable C. spinulosa, but C. brunoniana as a
possibility. C. brunoniana is rarer, so more interesting.
It is good to see a large full-grown plant as so much forest there has
been destroyed and used up. But because tree-ferns are OK in the sun (that
was the point of the trunk-habit!), as long as the base is among dense
undergrowth and does not dry up, I have seen quite a few decent-sized
plants of tree-ferns in a few areas, such as towards the Meghalaya border
north of Sylhet, near Jaintiapur (C. khasiyana) or down in the ravines at
Kalatoli, near Cox's Bazaar (a great place Professor Pasha showed me - with
C. henryi and a new species of Diplazium I found there, D. banglum), and of
course around Banderban and up to the Myanmar border beyond Ruma (C.
henryi) and have seen C. spinulosa about there too, though I didn't
collect it.
Can you revisit some time and throw a stick or stone up to grab a
pinnule? And take a zoomed photo of the lower stipes to show scales and
possible spines, then we can clinch its identity.
Best wishes,
Chris Fraser-Jenkins.

Another view. It was not possible to get close shot despite of its present
in top hill.

No, sorry - it is as you say entirely insufficient. All the literature
talks about the indument under the pinnules and I have said it hiundreds of
times. For tree-ferns we have to have a close up of the underside of a
pinnules and to see young sori as well. And we also need to know if the
stipe is spiny or smooth, pale or more-or-less black.
In general it looks most like the common C. spinulosa(syn.: Alsophila
spinulosa), but no one can tell from a general picture like this. I can
only say it's a tree-fern!
