This association is dominated by Ranunculus sceleratus or Rumex maritimus, annual wetland herbs which can reach a height of up to 1 m and a cover of 100%. It occurs mainly on the exposed bottoms of summer-dried fishponds, oxbows and water reservoirs. Substrate is usually deep, wet and nutrient-rich mud. It occurs in areas with moderately warm to warm and moderately wet climate in lowland and colline areas across the Czech Republic.
