This association includes low-growing stands with Lythrum hyssopifolia, Myosurus minimus, Plantago uliginosa, Ranunculus sardous and annual weed and ruderal species, which occur in periodically flooded depressions on arable land or recently abandoned fields. Most of these sites are flooded in precipitation-rich years and vegetation develops after drainage. Habitats are maintained by periodical disturbances, otherwise they are overgrown by tall perennial wetland plants, which results in the disappearance of competitively weak annuals. In the Czech Republic this community occurs in the Morava and Dyje floodplains and adjacent areas in southern Moravia and very rarely in southern Bohemia.
