A herb found wild enroute to Mayodia Pass in Lower Dibang Valley in Arunachal, which is above 2000 m altitude.
Precise altitude of the location where the plant was found is uncertain.
Found flowering in January.
I have no clue to its identity.
Please identify
Asystasia sp. ?? 

Actually it was at lower altitudes, 150-500 m.
Navendu Pāgé identified it as Codonacanthus pauciflorus, native to East Himalaya to Japan.
Agrees well with images in the following:

My guess worked ! 
You are right ...! Asystasia pauciflora is a synonym!
