Abstract

Phelipanche nowackiana, a new species in the Macedonian flora and Orobanche esulae, with one, very old data, are presented in this work. P. nowackiana is a serpentine-soil species, parasitic on species of the Brassiceae family, primarily the genera Alyssum s.l. (incl. Aurinia and Odontarrhena) and Bornmuellera. The range is Balkan countries (Albania, Greece, Serbia) and Turkey (Asiatic part), possibly further into western Asia. A population of this species grows on the host plant Aurinia saxatilis (L.) Desv. (Alyssum saxatile L.), in the gorge Matka (Skopje), alongside the bank of the river Treska. O. esulae is a Balkan endemic species confined to Serbia and Bulgaria. It parasitizes only species of the genus Euphorbia. So far, there was one, very old data, for its presence in our flora. The filed-researches, over a decade, revealed populations on several localities: Katlanovo, Veles (gorge of the river Babuna), Strumica (foothill of the Mt. Belasica), Kavadarci (village Drenovo), Debar (valley of the river Crn Drim), Mariovo (village Melnica), Gevgelija (village Moin). The host plants are Euphorbia-species: E. myrsinites, E. seguieriana subsp. niciciana, E. barrelieri and E. amygdaloides.
