Please help me identify this plant
Viola sp.
Yes It's Viola
Thank you but I could not find the name of the species. It grows in a sacred forest
Thanks! So it must be Violet odorata? It grows in a sacred forest
Yes it's Resembles 
Pl. post image showing the front of the flower.
Was it fragrant?
Any feedback in the matter pl.
I doubt it to be Viola odorata as it is introduced in India.
Is it reported as wild in your Floras?
It was taken in a sacred forest in Meghalaya. I did not get a clear photo of the front angle of the flower. It did not have any fragrance. Thank you
Thank you Sir. I’m not too sure If it had a fragrance. I’ll find out when I visit again 
What are the species of Viola listed in your area ?
Viola arcuata
Viola diffusa 
Viola patrinii
Thanks, ...
It may be Viola hamiltoniana as POWO & Checklist of Nepal consider Viola arcuata Blume to be a syn. of it.
I looked for specimens in GBIF from India, which I think confirms it as per specimens below:

Okay thank you very much
