Abstract

In this paper, two endemic Centaurea species were investigated in
terms of their chromosome numbers and karyomorphology. The chromosomal counts
confirmed the results of previous reports, that the genus Centaurea has different basic chromosome numbers. Centaurea urvillei subsp. hayekiana and Centaurea saligna are diploid taxa. C. urvillei subsp. hayekiana has
2n = 20 chromosomes and a different basic chromosome number of ten, and this
basic number is relatively rare for Centaurea.
C. saligna has 2n = 18 chromosomes,
and therefore has a basic chromosome number of nine, which is common in the
genus Centaurea. Satellite was
identified in the short arm of the chromosome IV. of C. saligna.
