Persicaria bistorta or Bistorta officinalis

Grows in shadow, in alpine pastures of Jura mountain range.
Many thanks to Danielle Pralong for the help in IDing this species. As Danielle pointed out, the generic placement of this species is unclear; belonging to family Polygonaceae, the literature I just consulted treat it as Persicaria genus. On the other hand, it has also been placed in Polygonum or Bistorta genus.
Hi Zlatan! Please note that the generic placement of this species seems to be in flux. Some authorities also place it in Polygonum or Bistorta. Thanks for your ongoing contributions!
