Abstract
Paper presents ecological and phytosociological relationships of Ctenidio molluscae-Seslerietum uliginosae (Caricion davallianae alliance) - association new-distinguished for Poland. Its phytocoenoses occur in the eutrophic habitats within Kielce county and such mezoregiones as Świętokrzyskie Mountains, Szydłowskie Highlands, Pińczowski Hump and Nida Valley. The association was compared with the analogous one from Czechoslovakia. It was also proved to be well floristicly and ecologicaly stabilized.
