Abstract


Viola uliginosa Besser is a European species mainly known from the Baltic Region. It is endangered in a significant part of its range. Research carried out in the southeastern part of Poland led to the discovery of numerous sites of Viola uliginosa. Fourteen new localities of this species were found in the area of the Kotlina Sandomierska basin. This paper presents information concerning the localization of all new sites, the abundance of Viola uliginosa at the sites and habitats this species occupies. A discussion regarding the endangered status of this species in the Polish flora is given.
