Description Hybrids in the genus Carex occur quite frequently. However, only one hybrid with C. fritschii as a parental species has been reported to date. In 2010, plants with an appearance transitional between C. caryophyllea and C. fritschii were found at two sites in southern Moravia, Czech Republic. The results of morphological and anatomical analysis show that the plants are in many respects similar to C.caryophyllea in morphology, but some plants possess a combination of characters indicating an intermediate position between C. caryophyllea and C. fritschii. The fertility of the hybrid plants varies widely, between fully sterile and completely fertile. The anatomical characters of the leaf cross-section correspond largely to C. caryophyllea, but the teeth on the adaxial side of the leaf demonstrate the hybrid's position closer to C. fritschii. Based on the results of analysis, the plants discovered are considered the new nothospecies Carex xmoravica between members of two different sections of the subgenus Carex (Mitratae and Acrocystis).
