The systematic position of Caeoma origani sp. nov., as well as Uredo euphorbiae-paralias and U. varthemiae are discussed, and lectotypification is provided for the latter species. Pucciniastrum epilobii is reported as new for the Middle East and Cumminsiella mirabilissima, Ochropsora ariae, Melampsora cf. amygdalinae, and Melampsora cf. salicis-albae are new for Israel.
