Újabb adat a magyarországi adventív flóra ismeretéhez: Polypogon viridis (Gouan) Breistr.

Polypogon viridis (Gouan) Bresitr., a new alien species to the Hungarian flora, was detected between the years 2016–2019. Water bent (P. viridis), originating from the Mediterranean basin, was recorded from several plant nurseries and outdoor flowerpots in Transdanubia, Hungary. The new Hungarian records fit into the observed phenomenon that ornamental plant trade is an important factor in the spread of this species. Morphological characterization and insertion of P. viridis into the Hungarian identification key are also provided in this paper. Since P. viridis was represented in large numbers at some of the Hungarian localities, future monitoring of its spread may be important to evaluate the invasiveness of the species in the country.
