The article presents three newly discovered interspecific hybrids of sedges found in the Czech Republic. The finds of two of them (Carex ×helenae and C. ×ploegii) are the result of authors' field work and subsequent revision of specimens in large institutional Czech herbaria, while the third, C. ×alluvialis, was documented by a herbarium specimen in the BRNU herbarium, collected in 1998. The finds of these wetland hybrid sedges are a supplement to the treatment of the genus Carex for the Flora of the Czech Republic, Vol. 9. For each of the hybrids, a detailed morphological description compiled on the basis of Czech plants is given and the location of the voucher specimens is mentioned.

Keywords: Carex ×alluvialis, Carex ×helenae, Carex ×ploegii, hybridisation, wetland sedges
