This herb was shot from Gori Valley area, perhaps this is again Persicaria nepalensis with white flowers..


Yes! Persicaria nepalensis! Perianth shows color variation from white to pink. Thanks for sharing.


Persicaria nepalensis (Meisn.) Miyabe is a common creeping herb on moist slopes in temperate and subalpine areas of Uttarakhand. Flowers may be pink or white.

Seems Persicaria alata Syn: Polygonum alatum – a common weed in moist places/cultivated fields ?


Thanks for your input Chauhan Sir!

As per The Plant List, Persicaria alata (Buch.-Ham. ex D. Don) Nakai is a synonym of P. nepalensis (Meisn.) Miyabe.

Here is the link for your kind perusal


Yes now known as Persicaria nepalensis

Apart from the Pink Knotweed (Persicaria capitata) we have this one too. Here are some photographs.
I am not sure of the last three photographs which may not belong here. Please advise.
Persicaria nepalensis (Nepal Knotweed)
Above Mcleodganj, Dharamshala, HP
1800m
15-16 August 2015
I found this one on the ground–not tall like the others, leaves larger, the red edges more prominent. Looks slightly different from the others but I can’t think what else it could be. Please advise if I am wrong in putting it here with P. nepalensis.

Yes! All pictures belong to Persicaria nepalensis (Meisn.) Miyabe. Family: Polygonaceae


I photographed this yesterday. Is this also P. nepalensis or a different knotweed? Unlike my other photos last year this one has very prominent black V marks but I understand that these can be variable in a species. Please advise. 2 images.


I think this is again Persicaria nepalensis. Winged petioles are characteristic.

I think matches with images by … at Polygonaceae Fortnight- Persicaria nepalensis “white” from Gori Valley :: NS May 21


Flower colors are pink, so could it be ‘white’ not the Persicaria nepalensis (Meisn.) H. Gross
