This association includes open to fully closed stands of Lemna minor, a tiny plant floating on the water surface. Often these stands are monospecific. Lemna minor has a broad ecological range, being most common in eutrophic water bodies. It occupies most types of water bodies except very large ones, where it is disturbed by wave action. In the Czech Republic Lemnetum minoris is the most common association of aquatic macrophytes, occurring mainly in the lowlands and at mid-altitudes.
