Impatiens …???
Since it is from old collections the quality of image is not so good.

Pl. check comparative images at

Could not get any match !


Impatiens drepanophora Hook.f.

Unfortunately not I. drepanophora
I. drepanophora is one of Impatiens with upcurved spur (curved over lower sepal, towards upper petal).

Your plant has apparently downcurved spur.


Any idea … ?

Any closeness to Impatiens vidyae R.C.Srivast. ?

I think looks different (though close) from Impatiens vidyae


Friend suggested Impatiens leptocarpa Hook.f. !

Please advise!


Yes it is I. leptoceras DC
