Persicaria filiformis

(Thunb.) Nakai

Polygonaceae


This species has gone through several name changes, as can be seen fron the list of synonyms. It has at times been listed as a variety of Persicaria virginiana, or even as Persicaria virginiana in the literature. The two species, whilst closely related, are considered as distinct in all modern reference works, and to have distinct distributions. Persicaria filiformis is native to much of Asia whilst Persicaria virginiana is native to N. America.
Some of the entries in this record were originally listed under Persicaria virginiana, but since they relate to the Asian species, they have been transferred here[
