These meadows occur on wet and base-poor soils. In some places a luxuriant moss layer can develop and a shallow peat layer may form on the soil surface. In contrast to the Angelico sylvestris-Cirsietum palustris, these meadows contain several species of suboceanic distribution, including the dominating Juncus acutiflorus. They are rather common in a restricted submontane region of northern Bohemia, but small isolated stands also occur at higher altitudes of the southern part of the Bohemian Massif.
