Persicaria mitisPersicaria mitis Assenov is a species of flowering plant in the family Polygonaceae, native to Europe.TaxonomyThe species was first described by Franz von Paula Schrank in 1789 as Polygonum mite. In 1966, Vulevi Ivan Assenov transferred it to Persicaria under the name "Persicaria mitis". However, this name had already been used in 1800 by Antoine Delarbre as a replacement name for Carl Linnaeus's Polygonum persicaria when this species was transferred to Persicaria. This would make Persicaria mitis Assenov an illegitimate name; however it has been conserved.
