The species are: C. spicata Boiss. (Sect: Cynaroides), C. tomentella Hand.-Mazz. (Sect: Cynaroides), C. screlolepis Boiss. (Sect: Cynaroides), C. amonicola Hub.-Mor. (Sect: Cynaroides), C. kurdica Reichardt (Sect: Cynaroides), C. haussknetchii Boiss. (Sect: Cynaroides), C. odyssei Wagenitz (Sect: Pteracantha), C. polyclada DC. (Sect: Acrolophus) and C. consanguinea DC. (Sect: Acrolophus)). The polen grains are tricolporate, prolate to prolate spheroidal, with sparsely or densely distributed spinules ranging from 0.50 to 1.73 ?m height and with irregular pores. P/E ratio in the grains ranges between 1.05 and 1.73. It was determined that the pollen features could be used in separation of some species studied. © EuroJournals Publishing, Inc. 2007.eninfo:eu-repo/semantics/closedAccessCentaurea L.Endemic speciesPollen grainsArticle1911441492-s2.0-38349086637N/A
