Perhaps Persicaria lapathifolia, photographed along Nagin Lake in Kashmir, please validate.
As per my observations, inflorescence are densely flowered and not interrupted in P. lapathifolia.
I would rather go with P. hydropiper here.
Comments are welcome.
Good that I am uploading plants from different places separately, especially when there is some doubt.

Requesting to please validate ID of this Persicaria captured near Manali, HP in October 2014.
I hope this is Persicaria hydropiper (based on FoI pics).
In old threads I have been told that P. hydropiper has lax flowered inflorescence. FoC or FoP also supports that. Yet overall looks of this plant is like that of P. hydropier – http://herbier.sesa-aude.fr/Polygonum-hydropiper. Please ensure leaf base is cuneate which is not clear in the attached pictures.
Thanks … for the info….
I am uploading a cropped pic of the leaf base…

These plants are flanking the roadside wherever there is running rainwater. The plants I photographed are growing next to cultivated fields. These are about three-feet tall and growing in clusters. I think this is Persicaria hydropiper but I am not entirely sure. Please advise.
