Orobanche caryophyllacea Sm. (Orobanchaceae) in Poland: current distribution, taxonomy, plant communities and hosts

The paper presents the current distribution of Orobanche caryophyllacea Sm. in Poland based on a critical revision of herbarium and literature data as well as the results of my field studies. The majority of localities are in south and south-eastern Poland: Małopolska Upland, Lublin Upland, Roztocze, Przemyśl Foothills, Pieniny Mts, rarely in the valleys of the Lower Vistula and Oder rivers or Wolin island. The distribution map in Poland is included. The taxonomy, biology and ecology of the species are discussed.
