Hi, Muthu ji,

May I request you to pl. post high res. images to see the details.

The id as Persicaria maculosa may need to be considered again as I do not find its distribution in the area as per POWO, CoL, FoPI.

There may be some possibility of Persicaria stagnina (Buch.-Ham. ex Meisn.) Qaiser, but difficult to say with these images.

Pl. post high res. images.
