Himalaya to S. China and W. Malesia: Assam, Bangladesh, China South-Central, China Southeast, East Himalaya, Laos, Malaya, Myanmar, Nepal, Thailand, Tibet, Vietnam as per POWO;India (Uttar Pradesh, West Bengal, Arunachal Pradesh, Assam, Nagaland, Mizoram, Manipur, Meghalaya, Darjeeling), Nepal, Bhutan, Bangladesh, Thailand, Sumatra, peninsular Malaysia (Cameron Highlands, Pahang), China (S-Yunnan, W-Guangxi, Guizhou, Sichuan), SE-Tibet, Vietnam, Laos, Myanmar [Burma] (Bago, Chin, Kachin, Magway, Sagaing, Shan, Yangon) as per CoL;
.
As per BSI Flora of India:
Very similar to Z. armatum but can be recognised from it chiefly by its short, condensed, axillary panicles and ferruginous-pubescent branchlets. As has been noted by Babu (1974) the frequent occurrence of reddish-purple anthers and prominent lateral nerves among the Indian material of Z. armatum brings the two species much closer than ever before. The indumentum pattern also varies considerably within the species in accordance with its geographical and altitudinal range.

ID validation pending !

Pl. check with images under threads at Zanthoxylum armatum

I do not think it is Zanthoxylum acanthopodium as per
http://www.efloras.org/object_page.aspx?object_id=109612&flora_id=2
Pl. also see keys of four species under Shrub for ID fro Rudranaath Track, Chamoli, Uttarakhand

I think it is Zanthoxylum acanthopodium DC., as per keys in BSI Flora of India.

MS/12/2019/4 – ID of a plant from Arunachal. : 16 posts by 6 authors. Attachments (1)
Sent by a friend on a trip to Arunachal.
Photo taken at Mishmi hills on Dec 5th. Longest leaf about 10 cm. A foot high plant. Any idea of sp family? No flowers or fruit available. 

Resembles Zanthoxylum sp,

Agree with …

The picture is not matching with any of the species in the net. Please suggest  which  species of Xanthoxylum

Please check Zanthoxylum oxyphyllum Edgeworth !

but … did you take those remarkable thorns on the leaves into account.
Z. oxyphyllum pictures on the net do not show any thorns. not only that they do not show any hairs on the leaves either. before my internet went dead a few days ago. i had puzzled over this plant and was working my way thru the taxonomic key.
I don’t remember seeing any thing that describes this very remarkable single picture.
… can you friend give us more details and pictures?

I contacted my friend for additional picture(s). But he has only this one.

so we will have to keep digging when time permits.
Checked in Flora of China, its looks like Zanthoxylum laetum, its wood climber. for more details, please refer below link.
http://flora.huh.harvard.edu/china/PDF/Zanthoxylum.pdf   

Is it listed in India? I could not find.
Parts between leaflets are winged but not sure in Z. laetum.
Leaf margin looks slight different.

I concur with the observation of …

I think … is correct. I could get the photographs matching the species suggested by him. Google search

It does not match with FOC illustration and GBIF specimens.
As per Flora of China, leaves are alternate. It further says: Trunk, branches, branchlets, and leaf rachises with prickles. Rachis of young leaves, petiolules, and midvein of leaflet blades puberulent.
In this there is no mention of prickles on mid vein of the leaflets.
Thus, identification at Crug Farm Plants appears to be wrong.

I think it may be Zanthoxylum acanthopodium DC., as per images and details herein.
BSI Flora of India says ” Leaves 3-foliolate or imparipinnate, up to 25 cm long; petiole and rachis armed with compressed prickles on both sides …”
