SummaryIn this study, chromosome numbers and morphologies are presented for four species growing naturally in Turkey. These species are Inula peacockiana (Aitch. & Hemsl.) Korovin, Cousinia boissieri Buhse, Scorzonera renzii Rech. f., Lactuca intricata Boiss. Chromosome number of studied species are Inula peacockiana 2n=20, Cousinia boissieri 2n=26, Scorzonera renzii 2n=14 and Lactuca intricata 2n=18. Also, karyotype analyses were made using the Bs200Pro Image Analysis Software. In addition, the karyotype asymmetry of each taxa was evaluated by different methods; TF%, AsK%, Rec and Syi, A 1 , A 2 , A, AI and Stebbins classification. The correlation between the karyotype asymmetries of the different taxa was calculated.
