Taxonomic revision of the genus Hesperis L. (Brassicaceae) and significance of morphological characters in species circumscription using multivariate statistical analysis

Generally, studies are not complete in the genus Hesperis and species delimitation have not yet been considered. In the current survey, morphological variation and species delimitation of different species of the genus Hesperis was carried out using the field, library and herbarium studies in Iran and Turkey. In order to perform multivariate analysis, 300 OTUs (Operational Taxonomic Units) were studied based upon 57 characters using MVSP and PAST software programs. Then, the dendrogram based on the Unweighted Pair Group Method with Arithmetic Average (UPGMA), defriended Correspondence Analysis (DCA) and Principal Component Analysis (PCA) were constructed. As a result of the present study, the similarity percentage of different populations belonging to 32 species of this genus were defined and fruit, stem, pollen grain, seed, and leaf were considered as the most important characters in species delimitation
