This community of forest springs is characterized by a well-developed herb layer and the dominance of Chrysosplenium oppositifolium. It occurs mostly on steep slopes in beech forests with a closed canopy. Soils are stony or gravelly due to eluviation of small soil particles. Ground water has an acidic or neutral reaction and stable temperature over the year. In contrast to the two previous associations, species richness is lower and bryophytes are more suppressed by tree litter. This vegetation type has suboceanic distribution and reaches its eastern limits in the Czech Republic. It occurs in moutainous areas of Bohemia.
