Morphological and ploidy level variation of Centaurea phrygia AGG. (Asteraceae) in the Czech Republic, Sovakia and Ukraine

Original language description

Centaurea phrygia agg. was studied in part of Central Europe (Czech Republic, Slovakia and Ukraine) to evaluate its karyological and morphological variation. Three ploidy levels were found: diploid (C. pseudophrygia, C. stenolepis and several populationsof C. phrygia s.str.), tetraploid (C. oxylepis and several populations of C. phrygia s.str.), and triploid (very rare, only single individuals). Only one taxon, C. phrygia s.str., comprises populations of two ploidy levels, but they seem to be geographically separated. Multivariate morphometric analysis confirmed the separation of the four taxa; the length and the width of appendages of middle involucral bracts, visibility of appendages of inner involucral bracts, the length and the width of an involucre, and the length/width ratio of middle cauline leaves are the most important discriminant characters. Several populations intermediate between two species (either C. pseudophrygia and C. stenolepis or C. oxylepis and C. phrygia s.str.)
