Talk:Polygonum polymorphum

Polygonum or Persicaria?

I bought one of these recently, but it was sold to me as Persicaria polymorpha - one of the synonyms listed in the article. But then I read this, which states that recently it was moved into Persicaria (2nd paragraph), but it also quotes the German magazine Gartenpraxis referring to the name Persicaria polymorpha as "erroneous". Are there any more authoritative sources that can shed any light? PaleCloudedWhite (talk) 23:17, 4 October 2015 (UTC)[reply]

Neither The Plant List, Tropicos or IPNI have any listing for Persicaria polymorpha. It may be the case that this species is better treated as a Persicaria than a Polygonum, but it appears that nobody has formally published the name Persicaria polymorpha.

It's a synonym of Koenigia alpina via Polygonum alpinum and Persicaria alpina. Peter coxhead (talk) 17:18, 24 February 2019 (UTC)[reply]
