This poor-fen association is characterized by dominance of tall sedge Carex lasiocarpa, which has a boreal distribution and may indicate long history of fen vegetation on particular sites. The vegetation is further composed of other tall sedges, tall dicot herbs, short sedges typical of poor fens, reed species and willows. Sphagnum fallax dominates the moss layer. The peat layer is deeper than in the previous association. The association occurs in the Šumava Mountains, Třeboň Basin and the Bohemian-Moravian Uplands.
