    Adatok néhány adventív növény előfordulásához a Nyugat-Dunántúlon
    (2023-12-21) Kulcsár, László
    In his publication the author provides data on the occurrence of 11 alien species in Wes­tern Transdanubia. Three of these species ( Euphorbia maculata, Euphorbia peplus, Muscari armenia­cum ) were observed to have spread rapidly in the past decade. It can be concluded that 4 species ( Ar­temisia annua, Crocus banaticus, Polycarpon tetraphyllum, Veronica filiformis ) have reached a state which is close to naturalization, while the other reported species ( Euphorbia lathyris, Senecio inaequi­dens, Silybum marianum, Veronica peregrina ) are casual in this region at present.

    A Leymus arenarius előfordulása a Kiskunságban
    (2021-04-29) Csecserits, Anikó; Bakró-Nagy, Zsolt; Kelemen, András; Rédei, Tamás; Tóth, Gábor; Tölgyesi, Csaba
    We present six new occurrences of a rare non-native species, the sea lyme grass ( Leymus arenarius (L.) Hochst.) in the Kiskunság region, Hungary. The populations grow in disturbed, secondary habitats (e.g., abandoned fields, recultivated landfills, surroundings of farms), but one of them begins to expand on the adjacent natural open sandy grassland. Most of the occurrences occupy several hundred square meters and in some cases it forms almost monodominant stands. We suppose that the species has the potential to become an invasive species in this inland sand region.

    Újabb adat a magyarországi adventív flóra ismeretéhez: Polypogon viridis (Gouan) Breistr.
    (2019-07-01) Wirth, Tamás
    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.
