Mitotic chromosome numbers are reported of 16 populations representing 12 taxa of the genus Cirsium Miller from Turkey. Six counts are new to science C. pseudopersonata Boiss & Bal. subsp. pseudopersonata (2n=34), C. simplex subsp. armenum (DC.) Petrak (2n=34), C. munitum (Bieb.) Fischer (2n=32, 34), C. macrobotrys (C. Koch) Boiss. (2n=34), C. sommieri Petrak (2n=34), and C. trachylepis Boiss. (2n=34)). One count (C. ciliatum subsp. szovitsii (C. Koch) Petrak (2n=34) is not consistent with previous record. The remainder confirm the very limited previous data. All counts are reported here for the first time from Turkey.
