Impatiens sp. for ID plz.
Balsaminaceae

Growing wild.

I had the opportunity to visit a part of Arunachal Pradesh in 2001-2003. It is a Botanist’s paradise. Unfortunately I could not lay hand on any book which discusses flora of Arunachal Pradesh with coloured plates. Army persons are best for recording flora of the area but you require professionals for identifications. Burkill’s book on history of botany in India is a testimony to my conviction.


How about Impatiens siangensis?
