Many thanks Satish ji for validating this ID.
*Impatiens tomentosa* and *I. oppositifolia* are allied, and confuse me
often.


All three plants are just next to each other, perhaps just a foot's
distance from each other.
All three have solitary flowers borne in axils, with spurs shorter than
flowers; leaves with serrated margins, upper surface hairy.
The bottom left picture seems to have more than one flower per axil -
because of the photo angle. Clicking on the photo will lead to a larger
photo on flickr. Each flower is borne in axil of single leaf.

The upper leaves are not obtuse at ends. Not sure about this being a
accepted variation.

Putting a small para from Rheedea Vol. 21(1) 23-80
2011<http://www.iaat.org.in/Rheedea21_23-80.pdf>-- The genus Impatiens
(Balsaminaceae) in the northern and parts of central
Western Ghats by Jyosna R.N. Dessai and M.K. Janarthanam ...
~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*Impatiens oppositifolia* L. is allied to *I. tomentosa* B. Heyne ex Wight
& Arn. but differs in stem, lateral sepals, lip and spur being glabrous. It
is also similar to *I. raziana* Bhaskar & Razi but differs in the presence
of lilac to pink-coloured flowers.

*Impatiens oppositifolia* is a very variable species with regard to leaf
shape and hairy nature of the pedicel (glabrous or with 1 or 2 rows of
hairs). Plants exposed to sunlight and growing in humus rich soil are tall,
have semicircular stem with broad leaves whereas those growing in shade are
stunted with quadrangular stem, linear and smaller leaves. There are
variations in the spur as well. The spur in material collected in Amboli
region is straight, hooked or straight and curved inwards at apex.
Grey-Wilson (1985) who stated that the Ceylon specimens exhibit variation
in leaf shape and size, however, did not mention any variation in flower.
