Persicaria hydropiper (L.) Delarbre is a common herb in semi-aquatic habitats of mid hills in Uttarakhand.

Shot near Bhowali (Naini Tal), Uttarakhand.
I am little skeptical about the identity. Drooping inflorescence and pink color of perianth (above) are pointing towards P. pubescens. 
Close up of ochrea and nuts character can tell if it is really P. hydropiper.
some links for comparison:
Experts opinion solicited.
Thank you ... for pointing out. I will have to check it with specimens/ plants.
Till checked its ID may be considered doubtful.

The pics are insufficient for me, but this may not be the case for the experts..
Please suggest id.. Persicaria maculosa?? 
P. maculosa should have denser inflorescence. Other characters are not clearly visible... but tentatively it should be either P. pubescens or other closely allied species.
