A shrubby plant seen near Pasighat, East Siang district, Arunachal Pradesh.

Flowering in mid November.
Looks like an Artemisia species to me.
Please identify

One of the stinging nettles ?  Not sure as the photo is not seen clearly in my desk top.

hairs of a stinging nettle are not seen- may be my  desktop ?

Urtica dioica female flowers??

The leaves and stem in my plant look quite hairless. So, I don’t know how well it would agree with Urtica dioica.

Looks like Urticaceae family…
Possibly Urtica spp.
Some spp/plants of Urtica don’t have stinging hairs on them.

I guess images are taken on mobile as such not so sharp for scrutiny.

Definitely Urticaceae. This can be Urtica angustifolia which differs from Urtica dioica in having sparser stinging hairs and comparitively shorter petioles.
Moreover it is much similar to U.dioica and also considered as eastern geographical variant of U. dioica which also matches the location of plant (Arunanchal Pradesh).

Thanks …! That seems to be a good line of thought. There are many subspecies of Urtica dioica and there is varying opinion on Urtica angustifolia (Urtica dioica subsp. angustifolia being a synonym). With the given quality of pictures, I think one cannot go more precise than this. In this light, … guess also makes sense – the plant being a variant of Urtica dioica. An image showing female inflorescence of (supposedly) Urtica dioica on Wikipedia looks very similar to the plant here:

Thanks, everybody, for the interesting discussions.

Just to put on record the various sources involved, Flora of China gives the following difference between the two:
7 (6) Plants often with dense stinging and setose hairs; leaf blade ovate or lanceolate, base cordate; petiole 1/6-1/2 as long as leaf blade.   9 U. dioica
+ Plants with sparse stinging and setose hairs; leaf blade lanceolate to linear, base rounded or notched; petiole 1/15-1/5 as long as leaf blade.   8 U. angustifolia
Based on this, the plants looks more closer to Urtica angustifolia Fisch. ex Hornem. However, neither Flora of China nor Catalogue of Life gives its distribution in India.
Flora of China says the species is similar to Urtica dioica in having dioecious plants, paniculate inflorescences, and similar stipule and achene features; however, it differs in having sparser stinging hairs, narrower leaves with a rounded base, and much shorter petioles. The taxa could either be sister species, or U. angustifolia could be an eastern geographical vicariant of U. dioica. It gives its distribution as China (Moist places in forests, thickets, stream banks; 800-2200 m. Hebei, Heilongjiang, Jilin, Liaoning, Nei Mongol, Shandong, Shanxi); Japan, Korea, Mongolia, Russia (Far East, Siberia).

…, I concur with your analysis.

Also consider Urtica hyperborea (also have distribution in the area) as per POWO specimens- one and two.
