Numerical Taxonomic Study on Some Centaurea L. Species

Abstract

In this study; numerical taxonomic study was carried out by using 23 morphological characters on 10 taxa (3 endemic) in Centaurea . Two methods used for numerical analysis; Clustering (UPGMA) and Principal Component Analysis (PCA). According to UPGMA Analysis, C. calcitrapa subsp. calcitrapa with C. iberica and C. antiochia var. antiochia with C. urvillei subsp. armata are the most related taxa. According to results of PCA analysis, minimum and maximum value of appendage broad and minimum value of appendage length are important characters for the classification of Centaurea .
