Chromosome number and ploidy level in seven Centaurea species from Croatia

salonitana and C. solstitialis) belonging to five sections were studied. Chromosome numbers and metaphase plates are presented. All species studied here were found to be either diploid or tetraploid with the exception of C. salonitana which presented both ploidy levels: one diploid and one tetraploid population were detected. 1919. Centaurea alba L.-2n = 2x = 18 (Fig. 1A).
