Have you check comparative images at Impatiens ?

Yes ...
I could also not find a match as per comparative images at Impatiens  

Sorry, I don't see enough details...
This is particularly difficult group with some unresolved problems and without detailed studies it is impossible to be sure.

Please, have you looked at what I know as Himalayan Balsam aka Impatiens glandulifera? Did you look at Impatiens oxyanthera?

Yes I did but no luck.
