Abstrakt: Adenostyles alliariae (Gouan) A. Kerner (Asteraceae) represents a single species of the genus Adenostyles in Slovakia. In the paper it is characterized from the point of view of chromosome number, genome size, breeding systems and distribution in Slovakia. Chromosome number 2n = 38 was confirmed in this study. Flow cytometric analyses resulted showed the genome size 18,19 pg for leaves and 19,4 pg for seeds. The flow cytometric seed screen method proved, on the basis of embryo to endosperm genome size ratio, that the species reproduces sexually. The occurrence of the species is bound to all higher mountain ranges of West Carpathians, above all to the Malá Fatra Mts., the Veľká Fatra Mts., the Nízke Tatry Mts. and Tatry Mts.

Kľúčové slová: nuclear DNA amount, chromosome number, occurence, mountain flora, Carpathians.
