In this study, some natural Vicia L. species growing in north-eastern Anatolia were investigated cytotaxonomically. Chromosome numbers and morphologies of the 15 taxa belonging to the Vicia genus were studied by using karyological and numeric taxonomical techniques. Data obtained on chromosome measurements were analysed by using cluster analysis. The chromosome numbers of these taxa have been found as 2n = 10, 12, 14 and 24. The results were considered in conjuction with the literature and karyological analysis results.
