Can you identify this flower?
I am not sure but I think it is water leaf plant ( called sambar cheera ).If you see other pictures, the leaf and flower color matches but I am not sure as I do not know how the flower looks when it is bloomed ( in your picture).
You can see this site http://papanasini.blogspot.in/2012/02/cylon-spinach-sambar-cheera.html

I got a picture of the above-mentioned plant from my house, unfortunately, it is not having flowers and I will get back when it will have one.


Hope this helps!
