Sempervivum ciliosum belongs to the group of yellow-flowered houseleek species (S. ciliosum complex) endemic for the territory of the Balkan Peninsula. Concerning the traditional taxonomy of genus Sempervivum, there are several taxa included in the above-mentioned group (S. ciliosum, S. jakucsii, S. klepa, S. octopodes and S. galicicum). However, due to highly expressed phenotypic variability, it isn't possible to certainly establish whether all taxa from that group, including S. ciliosum as a type species, are morphologically clearly defined. The aim of this study was to analyze the level of variability of morphological traits within the populations of S. ciliosum, taken in a narrow sense. Measurements of 36 quantitative traits of the vegetative and the flowering region of S. ciliosum subsp. ciliosum, including populations from Bulgaria, Greece and North Macedonia, were processed in STATISTICA 8.0. Results of Descriptive statistics, Correlation analysis and Univariate variance analysis (ANOVA) indicate that most of the analyzed traits express moderate to high variability within all examined populations.
