The paper gives information concerning floristic, phytosociological and habitat characteristics of meadow communities with Sesleria uliginosa Opiz found in the vicinity of Włodowice near Zawiercie (the Silesian-Cracow Upland). 14 phytosociological releves were made in patches of meadows representing the Molinion alliance which occur in lower parts of the karstic denudation step (cuesta). The comparison of wet meadows with Sesleria uliginosa participation from Włodowice with chosen communities from Poland and some other countries evidence their attachment to the Molinion alliance.
