Persicaria pensylvanica View in CoL ( L.) M.Gómez, Anales Inst. Segunda Enseñ., 2: 278. 1896.

( Polygonaceae )

Naturalized neophyte new for the flora of the province of Mantova (Lombardia) ( Banfi & Galasso, 2010).

ITALY. Lombardia. Prov. Mantova: Viadana, river Po W of the bridge, sandy river bank, few plants, 15.09.2014, F. Verloove 11058 ( BR) .

A native of North America, this species became natu- ralized in Europe, especially in riparian habitats. In Italy it is known from the northernmost regions ( Celesti-Grapow et al., 2009a). It is here reported for the first time from Mantova province in Lombardia .

This species is obviously naturalized along river Po but usually occurs in small populations. It does not seem to be an aggressive invader.
