Sažetak
Affinity relations within the Thalictrum genus, especially within the Thalictrum minus complex, have not been resolved, and the group's taxonomy is only provisional. With the aim of resolving this problem 4 characteristics (length-L, width-W, stigma length SL and number of ribs-R) have been analysed by biometry on 47 samples of T. minus complex population from the wider European area. The material was compared with the other species of the genus and with the non-European representatives. Tha data were examined by standard statistical tools and by the cluster and PCA analysis. The characteristisc L, W and SL showed regular distribution. The R feature is prominently asymmetric to the left. The correaltion amnog the characteristics are of the expected type. The results of the cluster and PCA analyses show moderately prominenet groups that cannot be connected with the existing sample classification or their geogrpahic position. Apart from the considerable variability, the analysed characteristics do not show diagnostic value within the complex.
