Abstract		Since the end of the 19th century, six species from the Bromus erectus group have been recorded for Slovenia: B. erectus HUDSON s.str, B. transylvanicus Steudel, B. condensatus HACKEL, B. stenophyllus LINK, B. pannonicus KUMMER and STENDNER and B. moellendorfianus (ASCHERSON and GRAEBNER) HAYEK. Since the delimitation of the taxa is stilt unclear, the purpose of the research was to investigate the discriminative power of distinguishing characters, used in various floristic works and also some new potentially useful distinguishing characters, subsequently to confirm whether these taxa really occur in Slovenia and finally to state their distribution. Besides the classical 'intuitive' approach to this problem, some methods of numerical taxonomy were used. The study was based on material fmm the herbarium LJU and second author's private collection. In the analysis 198 individuals were taken into account and 48 characters were investigated. The data were analyzed using hierarchical clustering and ordination methods (principal coordinate analysis, discriminant analysis) as well as some univariate statistical methods. The results of the analysis confirm the occurrence of B. erectus s.str., B. transylvanicus and B. condensatus in Slovenia. (Abstract truncated at 2000 characters)
