Fascicles of Flora of India Fascicle-18 Rosaceae genus- Prunus mentions presence of two vars. of P.cornuta. The variety P.cornuta var. villosa is mentioned as having leaves with cuneate bases.
Sir, i am thankful to both of you.
I was not questioning your ID, rather i wanted to clear my doubt. 
Now I am taking it as Prunus cornuta (Wallich ex Royle) Steudel (Rosaceae).

Yes it is Prunus cornuta to me too.
Undoubtedly, it is Prunus cornuta- Wild Bird Cherry, Called asJaman, Jamni in erstwhile Mahasu Region.
New leaves are poisonous to cattle and cause death due to the presence of HCN. fruits are edible and the bear relishes it by climbing the tree and squeezing the branches off ripe fruits and eating the fruits. In the process many small branches get broken.

The flower clusters are described as being "drooping" in Polunin-Stainton's 'Flowers of the Himalaya' but that was far from the case in the trees here.

Kindly identify this medium sized tree with spherical green fruits, photographed by the roadside in Dalhousie, Himachal Pradesh in May 2017.
Fruits about 12 mm in diameter.
I couldnt clearly identify the nature of whitish twisted pod-like things seen in the second photograph centre-top. Are they flowers or buds? Other instances were seemingly more deformed but photographs have not come clear.
The attachment here resembles to Prunus cornuta - Wild Bird Cherry, commonly known as Jamni, Jaman in Hills. Bears (Bhalu) relishges thr fruits. We, human being also enjoy it for its special taste & aroma with staining of our mouth with bluish violet stain.
Thank you ... Would the pod-like things in the second picture be infected fruits as mentioned on http://www.flowersofindia.net/catalog/slides/Himalayan%20Bird%20Cherry.html ?

Nice observation if it is correct. 
Yes. this is certainly an insect gall. The leaves of this tree are infested with galls as they go on maturing till dehiscence.

This one was again shot from Chakrata region, I am not sure if this same or different species of Casearia....
please provide id clues..
This does not appear to be Casearia as flowers are not in the axillary. 
It should be Padus cornuta (=Prunus cornuta)

Thank you very much … for this convincing identification..
