These are two species – notice difference in colour and shape of lateral petals.
From Sikkim only, about 50 Impatiens species are known…
Image 1 looks closeness to Impatiens yui S.H.Huang and image 2 is Impatiens puberula DC..
We should ask to Dr. Gogoi regarding this. Researchgate .
the white flowered plant with pink vein is Impatiens uncipetala C.B. Clarke ex Hook. f.
The pink flowered plant is Impatiens decipiens Hook.f.
Is there any connection between Impatiens uncipetala and Impatiens yui ?

Pl. check with Impatiens decipiens ?
I guess this sp. has no record for Nepal. Could you please check?
