Can be Zanthoxylum sp. ..
Please check for Zanthoxylum oxyphyllum (Rutaceae).
Zanthoxylum is represented by following 4 species in Uttarakhand:
1) Z. acanthopodium which is an erect shrub or tree; petiole and rachis are always winged
2) Z. armatum which also have distinctly winged rachis and petioles.
3) Z. oxyphyllum with wingless petiole and rachis; climbing or scandant shrub, evergreen, flowers in dense umbellate terminal and axillary clusters.
4) Z. rhetsa which is a tree and found upto 600m altitude only.
Considering this the plant in discussion should be Z.oxyphyllum. If not then it is an addition to Flora of Uttarakhand. Flora of India vol-4 page376-391 has the details of all species of Zanthoxylum found in India.
If you have specimens check for revurved prickles on lower side of rachis. Leaflets are crenate to glandular serrate along margins as mentioned in Flora of India and Osmaston (1927).

Zanthoxylum oxyphyllum Edgew. ??

Yes, appears close to Zanthoxylum oxyphyllum as per image and references herein.
But Flora of China says leaves 11-19-foliolate, but I see only 9 leaflets.

As per keys in Flora of Bhutan at Zanthoxylum, it say 6 to 10 pairs of leaflets. but in the description it say 1 to 10 pairs (may be by mistake or printing mistake).
I also check other species as per these keys, but could t find match with any other species.
I think there may be 11 leaflets in some of the leaves.
I guess you are right ...!
