North-American grass Glyceria striata (Lam.) Hitchc., a newcomer in Croatian flora

Here we report the first records of the North American grass Glyceria striata (fowl mannagrass or ridged glyceria) in Croatia. Four localities were found in the Gorski Kotar region (Alpine Biogeographical Region) along the watercourses and two additional localities were observed at forest margins and clearings on the outskirts of the city of Zagreb (Continental Biogeographical Region). The species has been classified as a naturalized neophyte and warrants monitoring in the forthcoming period.
