Abstract:

This paper is devoted to providing chorological information on genus Sonchus species in Ukraine and to mapping their distribution. We have processed the materials of the herbaria KW, KWHA, KWHU, LW, LWKS, LWS, SOF, MW and also information from on-line resources http://www.ukrbin.com and https://www.inaturalist.org. Also we carried out several expeditions. Maps were constructed using SimpleMappr. The species of the genus Sonchus occur throughout Ukraine. Sonchusasper, S. oleraceus and S. arvensis grow mostly on anthropogenically transformed areas. Sonchuspalustris occurs more often in swamps and wet meadows. Here we also found out that Sonchus species in Ukraine should be classified as aboriginal. Previously, they were considered adventitious for the territory of Ukraine.
