| Cousinia is the one of largest genera in Asteraceae family, after Astragalus, Cousinia is the largest genus, with over than 270 species and 43 sections in Iran. Morphological studies and micro-morphological studies of the leaf characters were performed in 31 species of the genus Cousinia (sections Albidae, Cousinia and Stenocephalae) growing in Iran. In total 17 morphological characters and 11 micro-morphological characters of the leaf epidermises were scored. UPGMA clustering and PCA ordination based on morphological characters almost separated the three sections. However, the same analyses based on micro-morphological characters did not completely agree with morphological results. Combined analyses of micro and morphological characters suggest that C. chlorocephala has closer affinity with the section Stenocephalae. It seems use of both micro-morphological and morphological characters for analysis, show species relationship clear than only morphological result data analysis. According to the results of the relationship of the species using the total characteristics of the grouping of this taxon, it needs to be revised again and molecular studies in this field are needed for more certainty. | ||
