Chromosome numbers were determined for 97 samples of 95 sedge taxa (Carex) from the following countries: Austria (6 records), Bulgaria (1), the Canary Islands (Spain, 1), Cape Verde (1), the Czech Republic (51), Hungary (1), Italy (2), Norway (8), Russia (15), Slovakia (1), Sweden (1) and 9 North American plants cultivated in Czech botanical gardens. Chromosome numbers for Carex argunensis, C. callitrichos, C. campylorhina, C. flavocuspis subsp. krascheninnikovii, C. paniculata subsp. hansenii, C. pallida, C. quadriflora and C. xiphium are reported here for the first time. The first reports are presented for the European portion of the distribution area of Carex obtusata and for the Central European portion of the distributional areas of C. chordorrhiza, C. otrubae, C. rhizina and C. strigosa. New counts for the Czech Republic fill the gaps in the karyological data for this genus in relation to the Flora project in the Czech Republic.
