The chromosome numbers and karyotypes of five species of the genus Bellevalia distributed in Turkey were analyzed. These taxa are B. anatolica B. Mathew & Özhatay, B. fominii Woronow, B. kurdistanica Feinbrun, B. rixii Wendelbo, B. turcica Pınar & Eroğlu. Three of them (B. anatolica, B. rixii and B. turcica) are endemic in Turkey. The chromosome numbers of all studied taxa were determeined as 2n=2x=8. Haploid chromosome lengths varied from 57.78 µm (B. fominii) to 68.17 µm (B. anatolica) among species. Karyotype analysis showed that Bellevalia taxa generally have median (m), submedian (sm), and subterminal (st) chromosomes, but not subterminal chromosomes in B. fominii species.

The somatic chromosome numbers and karyotypes were examined in five Bellevalia taxa including two endemic species of B. chrisii and B. gracilis distributed in Turkey. The chromosome numbers were determined as 2n=2x=8 in all studied taxa [B. chrisii Yıldırım & B. Şahin sp. nov., B. glauca (Lindl.) Kunth., B. gracilis Feinbrun, B. longipes Post, B. sarmatica (Pallas ex Georgi) Woronow]. The karyotype formula was determined as 2m+sm+st in B. chrisii and B. longipes, 3m+st in B. glauca, B. gracilis and B. sarmatica. The findings for each of the analyzed taxa are compared with the results of previous studies.

The somatic chromosome numbers and karyotypes were examined in seven species of genus Centaurea L. distributed in Turkey. The chromosome numbers were determined as 2n=2x=16 in C. behen L. and C. solstitialis L.; 2n=2x=18 in C. cynarocephala Wagenitz and C. agregata Fisch. & Mey. ex DC. ssp. agregata; 2n=2x=20 in C. iberica Trev. ex Sprengel; 2n=2x=26 in C. balsamita Lam.; 2n=4x=36 in C. virgata Lam. All of the chromosomes had centromeres at median point (M), median region (m), and submedian region (sm). Satellite chromosomes (sat-chromosomes) were observed only in C. virgata. The findings for each of the analyzed taxa are compared each other and with the results of previous studies.
