Conyza sumatrensis (Erigeron sumatrensis Retz., Conyza albida Willd. ex Spreng.), a recently recognized alien in the flora of the Czech Republic, was found in the northeastern part of this country. The species had been reported from Bohemia (Prague) in 2020. In 2022, it was found in the eastern part of the Czech Republic. One plant found in the town of Třinec (Czech Silesia) might indicate the initial phase of an invasion of this species in the region. Detailed photographic documentation of the species is provided. Possible pathways of introduction are also discussed.

Keywords: Central Europe, Erigeron, invasion, neophyte, planting groundcover plants, road transport, Silesia
