Abstract
This paper concerns the cytogenetic investigation of the Croatian endemic species Fibigia triquetra (DC.) Boiss. (Brassicaceae). The number of chromosomes in all investigated cells from three populations of Fibigia triquetra was 2n=2x=!6. Chromosomes were small and ranged from submetacentrics to acrocentrics. One chromosome pair had a relatively small satellite. Although meiosis was not completely regular, irregularities were not very frequent. Low pollen germination rate was probably due to these irregularities. As the species is perennial, weakness of seed germination seems not to be important for its survival.
