Sažetak
Thalictrum L. (Ranunculaceae) genus contains several taxonomically difficult groups, including T. minus complex which has different taxonomical arrangements. Biometric methods were used with a purpose of bringing some more light on this subject. Four morphological fruit characteristics (number of fruit ribs, stigma length, fruit length and width) were measured on 69 samples of the Thalictrum genus from Europe with emphasis on the T. minus complex. Highest variability for the characteristic stigma length was established. According to Kolmogorov-Smirnov test fruit length and fruit width was normally distributed, while the nukber of fruit ribs was distinctly asymmetric to the left. Multivariate analyses did not show the diagnostical values of the examined fruit characteristics in the T. minus complex as well as in Thalictrum genus in Europe. The correlation among the characteristics and those between fruit characteristics and the geogrpahical longitude and latitude were established. Shortening of the fruit was observed to the east, as well as the narrowing of the fruit to the northbound direction, all showing clinal variability of these two fruit characteristics.
