<i>Orobanche elatior</i> Sutton and <i>Orobanche centaurina</i> Bertol. (Orobanchaceae) in the locality “Kozjak” (Skopje) in North Macedonia

Abstract

The field researches, carried out in the locality “Kozjak†(v. Nova Breznica, Skopje), revealed the exist-ence of two species: Orobanche elatior and Orobanche centaurina. The presence of Orobanche elatior, in the flora of North Macedonia is already known, while Orobanche centaurina is a new species. This finding, despite the latest distribution data, definitely incorporates the territory of North Macedonia, in the distribution areas of the both species. Centaurea grbavacensis, Centaurea atropurpurea and Centaurea salonitana, for Orobanche elatior and Jurinea polycephala, for Orobanche centaurina, are, so far, un-known to be host plants neither for these or any other Orobanche species. The deviation, concerning the dorsal line of the corolla, by the both species, from the locality “Kozjak†(v. Nova Breznica, Skopje), is discussed. Photographs of the species habitats, the whole plants and their different parts, crucial for the determination, are also taken.
