Abstract The chromosome numbers of several Mediterranean and Central European species from the genusCentaurea L. have been studied. The material was collected in natural habitats, exceptC. thracica andC. maxima. The numbers forC. cineraria (2n = 36; tetraploid!),C. subtilis (2n = 22),C. sonchifolia (2n = 44),C. sphaerocephala (2n = 44),C. napifolia (2n = 22),C. achaia (2n = 22),C. thracica (2n = 18), andC. maxima (2n = 28) are reported for the first time. For the following species earlier counts are confirmed:C. cineraria (diploid, 2n = 18),C. maculosa (2n = 18),C. rhenana (2n = 18),C. triumfettii (2n = 22 + 0−1 B; first report of accessory chromosome for this species),C. scabiosa (2n = 20 + 0−3 B),C. crassifolia (2n = 30). B-chromosomes are reported for 3 populations ofCentaurea scabiosa from Berlin; they lack in 2 populations from Bayern and Hessen.
