ABSTRACT
The paper presents the distribution and habitat conditions of Riccietum fluitantis
Slavnić 1956 (Lemnetea minoris class) in oxbow lakes of south-western Poland. During research
done in 2000–2018, 11 localities of this community were found. The main threats to Riccietum
fluitantis in oxbow lakes in south-western Poland are changes in water levels and physicochemical
properties. Problems associated with distinguishing Riccietum fluitantis are discussed
