This association of moderately rich fens is very poor in both vascular plant and bryophyte species. The stands are usually dominated by Eriophorum angustifolium, Trichophorum cespitosum and Warnstorfia sarmentosa. Grasses and broad-leaved dicots are absent, and peat mosses are not dominant. Concentrations of calcium are lower than in the previous association. Concentration of major nutrients in the environment and vegetation productivity are extremely low. The peat layer is shallow and grows very slowly. The association is typical of the tundra zone of northern Europe. In the Czech Republic it occurs only in the Krkonoše Mountains at altitudes above 1300 m, often close to bog complexes.
