The focus of this Bachelor thesis is expansion of the genus Antennaria (Asteraceae) in the Slovak area of the Karpaty. The purpose was to create an electronic database about the extension of two representatives of the genus Antennaria, namely A. dioica and A. carpatica on the basis of herbarium analysis. The obtained data were rewritten using the program Microsoft Office Excel 2007. Complete electronic database contains detail informations about the extension of two species in individual districts, according to the phytogeographical lokations of Slovakia: location data according to the original text, revised locations identified by the current names, names of plant collectors, collection dates, data about ther vertical range, habitats, and abbreviations of herbarium collections where the studied data are stored. Extensions of Antennaria carpatica were identified only in 2 phytogeographical units out of a total of 31, especially in the Tatry, where it was abundantly represented in all three parts and in the Nízke Tatry, where its occurrence was rare. The occurrence of Antennaria dioica species is much more frequent in Slovakia, it was identified in 26 phytogeographical locations. The largest expansions were identified in the Strážovské and Súľovské vrchy, Slovenské stredohorie, Slovenské rudohorie, Fatra, Nízke Tatry, Tatry, Podtatranské kotliny, Východné Beskydy, Slovenský kras, Malé Karpaty, Muránska planina and Západné Beskydy. A bit smaller expansion was in areas: Ipeľsko-rimavská brázda, Podunajská nížina, Južné Biele Karpaty, Považský Inovec, Slovenský raj, Slanské vrchy, Turčianska kotlina, Západobeskydské Karpaty and Spišské vrchy. In areas Záhorská nížina, Devínska Kobyla, Tríbeč, Vihorlatské vrchy, Pieniny and Bukovské vrchy, the occurrence was rare. In some locations, it was not even identified: Burda, Košická kotlina, Východoslovenská nížina, Stredné Pohornádie and some sub-areas in the Slovenské stredohorie. The most common recorded habitats were grasslands, meadows, road edges, dry spots and bright deciduous forests. The soils was granites, limestones, cremans, dolomites and andesites. Altitude heights are in a wide vertical range, from 140 m above sea level. (Devínska Kobyla) up to 2100 m above sea level. (Nízke Tatry).
