This could be Strobocalyx arborea (Buch.-Ham.) Sch.Bip. ... synonym: Vernonia arborea Buch.-Ham.)

Genus ID help by Arun Kumar N in Instagram for my earlier post.

I think it looks different as per images at 
https://efloraofindia.com/efi/vernonia-arborea/

Also does not match any closely related member at

Many thanks Garg ji. I am curious to know the correct ID.

Quoting Arun Kumar N's comment in Instagram: "One of the arboreal species of Vernonia, now Monosis".

Thus, there could be chances of Monosis wightiana DC.  / Vernonia monosis Benth. ex C.B.Clarke ... both synonyms of Strobocalyx wightiana (DC.) Sch.Bip.

Regards.

[J.M. Garg]

I do not think so.

OK, thanks Garg ji.

I hope the ID gets resolved soon.

Garg ji, requesting you to take a relook at the links that you have pointed out.

The photos and herbaria show trees in bloom. 

The posted plant is in budding condition therefore looks slightly different. Otherwise the inflorescence matches very well. The leaves match very well.

I put the photos from the post of Strobocalyx arborea (Buch.-Ham.) Sch.Bip. :: The Nilgiris :: Jan 28, 2026 · 9:41 AM IST on Instagram. Again Arun Kumar N commented that it is Monosis coming into bloom.

Regards.

Dinesh

[J.M. Garg]

Shape of the buds is also different if you see high resolution details at

https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:251886-1

It is not even a Vernonieae member as per images at

[Dinesh Valke]

Garg ji, 

I did not understand your last response:

Images can be seen at 
https://www.inaturalist.org/observations/337793443

What does it imply ? This is the URL to my observation.

The links you have provided of Herbarium JCB and POWO do not have any illustration of buds, all of the images show inflorescence either in flowering or fruiting. I am not able to judge the shape of the buds in those images.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is a link to see the images of Strobocalyx arborea so that we get a fair idea of leaves and buds of Strobocalyx spp.
https://www.inaturalist.org/observations?place_id=6681&preferred_place_id=6681&taxon_id=937241

in budding stage:

Going through the links, I agree. 

[Dinesh Valke]

Many many thanks Garg ji.

I think we can take this as Strobocalyx arborea as per observations in iNaturalist and as per 
https://indiaflora-ces.iisc.ac.in/FloraPeninsular/herbsheet.php?id=1748&cat=7
https://indiaflora-ces.iisc.ac.in/FloraPeninsular/herbsheet.php?id=1789&cat=7

Many many thanks Garg ji.

Key Visual Comparison (got from the internet)

Feature	Strobocalyx arborea	Strobocalyx wightiana
Habit/Size	Massive tree; can reach 15–26 metres (exceptionally 36m).	Medium tree; generally smaller and more typical of tropical dry evergreen hills.
Branchlets	Cylindrical and velvety/tomentose (covered in fine hairs).	Angled branchlets; typically less densely hairy than S. arborea
Leaf Underside	Densely velvety on the underside; leaves often clustered at branch ends.	Visibly distinct secondary and tertiary nerves on the underside; leaves are generally less hairy.
Leaf Base	Wedge-shaped and often asymmetrical.	.Generally elliptic to lanceolate; often more symmetrical than S. arborea

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

From the above details, to me, the posted plant best fits Strobocalyx arborea (Buch.-Ham.) Sch.Bip. because of following:

• branchlets are cylindrical and velvety/tomentose 
• the leaf underside is densely velvety 
• the leaf base is wedge-shaped and often asymmetrical.

Regards.
