Abstract: Seven quantitative and four qualitative characters were examined during three years in two native populations of Ophrys scolopax Cavan. ssp. cornuta (Steven) Camus in Hungary (Pécs and Kunpeszér). The total number of the examined individuals was 212. The observations were made on living plants in their original habitat. The locality- and generation-dependent differences were analyzed by univariate statistical tests (F, T and chi2 tests). Significant differences between the two populations were found in some characters. The most consistent ones among them are the length of the horn and the colour of the sepals and petals. Furthermore, a multivariate analysis of all the observed characters was carried out. A similarity matrix was calculated by Gower's formula (Gower 1971) and a dendrogram was constructed on the basis of the Sokal's weighted pair method (Podani 1980). The dendrogram shows well separated groups.
