Riza Binzet, Irfan Kandemir and Nermin Orcan
Abstract
Twenty-five Onosma L. (Boraginaceae) taxa belonging to two subsections (Haplotricha (Boiss.) Gürke and Asterotricha (Boiss.) Gürke) were classified by numerical taxonomic methods from Eastern Mediterranean region in Turkey. A total of 30 metric and 60 non-metric morphological characters were utilised for the genus Onosma. The classification obtained by numeric taxonomic methods was compared to that of obtained by conventional methods. The positions of O. bracteosa Hausskn. and Bornm. and O. taurica Pall ex Willd. in Asterotricha subsection were better resolved by numerical methods. Although belonging to different subsections, O. rutila Hub.-Mor. showed close morphological relationship to O. roussaei DC. In general, both (numerical and classical) classifications agreed forming in similar groupings based on morphological similarities. Newer Onosma key was also provided
