Piwowarczyk, Renata | Przemyski, Alojzy
A new locality of Orobanche coerulescens Stephan ex Willd. in the Wyżyna Małopolska upland (Garb Pińczowski hummock) in central Poland is presented. Over 290 specimens were recorded in a xerothermic grassland of the class Festuco-Brometea comprising species of the class Koelerio glaucae-Corynephoretea canescentis on alkaline, sandy soil. O. coerulescens is extinct at the majority of its localities in Poland and only two localities are known at present.
