This association includes marsh vegetation dominated by Bolboschoenus planiculmis and B. laticarpus, accompanied by annual or perennial wetland species and weeds of arable land. It occurs in persistent puddles which are flooded in spring and gradually dry out in summer, most frequently on arable land, but also in meadows, near water bodies or in abandoned sand pits. It has been recorded in lowland areas of northern and central Bohemia and southern Moravia.
