Herb for id from Amarkantak, M.P.-NS August 06 : 7 posts by 3 authors. Attachments (3)
This herb was found growing near Amarkantak, M.P. (July 2016).
I need the expert opinion for its id, I think this belongs to Caryophyllaceae..
Please suggest id..!!

Alternate leaves, racemose inflorescence, 5 stamens indicate some other family. Primulaceae?

Is it Lysimachia obovata…? Thanks for the lead …!!
