摘要：In this work the non-native flora of the town of Omiš was analysed. It numbers 84 taxa, which equals 13.68% of the complete flora of the city of Omiš (614 taxa). Non-native taxa present exclusively in culture were not analysed in this work. The most common family is Asteraceae s. str. (16 taxa; 19.05%) and the most common genus is Amaranthus with six species. The predominant life forms are therophytes (42.86%) and phanerophytes (32.14%). The prevalence of non-native taxa was recorded on arable surfaces (59 of taxa) and ruderal habitats (51 of taxa). According to the naturalisation status, the most dominant are casual taxa (57.14%) and according to the mode of introduction the most numerous are deliberately introduced taxa (63.10%). Most non-native taxa originate in America (47.62 %), followed by those that originate in Asia (29.76%).
