Abstract
Wolffia globosa is a small free-floating aquatic plant native to the Southeast Asia and invasive in Europe. Between the years 2017 and 2022 it has been found in Czechia for the first time in this country in wetland habitats at seven sites. Occurrences of alien W. globosa were first recorded in the Central Bohemia region inside the Site of Community Importance Libické luhy, then by two sewage treatment plants and one adjacent fishpond in South Bohemia and in the Elbe River near the cities of Přelouč, Lysá and Labem, Obříství and Hřensko. At four sites, W. globosa has been recorded in flowing waters for the first time in Europe. The mode of introduction remains unknown.
