This suboceanic mire vegetation type occupies inundated hollows and their margins and is dominated by Rhynchospora alba in the herb layer, and Sphagnum papillosum and S. tenellum in the moss layer. In western Europe, it occurs on blanket bogs, whereas in the Czech Republic, it is found in mires near fishponds, in which the vegetation surface is isolated from the ground water by a deep peat layer. The water is thus poor in minerals and nutrients and has a low pH. This vegetation type is fragmentarily developed in central Europe and it lacks a number of subocenic species typical of western European stands. In the Czech Republic this association occurs in the Třeboň and Doksy Basins.
