Polygonaceae Fortnight: Persicaria sp. for ID from Chopta Uttarakhandr-GSMAY47 : 4 posts by 3 authors. Attachments (2).
Persicaria sp. photographed from near Chopta in Uttarakhand.
Looks like P. capitata but leaves appear to be larger, please help in ID.

Probably B. affine.


Sir, Chopta is too low altitude (27-2800m) for B.affine which occur above 3500m in Uttarakhand. It may be Bistorta macrophylla.


Thanks … for possible ID.


It looks different from both Bistorta affinis (D. Don) Greene as well as Bistorta macrophylla (D.Don) Soják
Can it be Bistorta milletii as per Flowers of India and GBIF specimen- one, although I find distribution in Nepal and east of it only?


I shall check and let you know.
