Need id help of this flower: 2 images.
Seen this flower near Dikchu at East Sikkim, on Nov 2022. 
Looks like a member of the Acanthaceae family. Please id this flower.

Looks like Strobilanthes penstemonoides (Wall. ex Nees) T.Anderson  !

This is definitely not Strobilanthes pentstemononoides – note the pubescent corolla.
I think it is Strobilanthes pubiflora J.R.I.Wood and is one of the first photos I have seen of this species, which is found in western Bhutan, Darjeeling and Sikkim.
