Carex lacustris is abundant and often a dominant of calcareous, north-temperate wetlands. Sometimes extensive stands are seen without fertile culms. Rare hybrids between Carex lacustris and C. hyalinolepis, C. pellita, C. trichocarpa (P. M. Catling et al. 1989), and C. utriculata are known; the hybrids are sterile and intermediate in morphology and can form extensive clones.
