Centaurea acicularis species was illustrated on Plate 911 of Flora Graeca, based on material collected by Sibthorp, probably on the island of Leros. It is an almost acaulescent perennial, growing in a variety of rocky habitats on the East Aegean islands (being particularly common on Ikaria) and adjacent parts of W Anatolia, but not crossing over to the Kiklades. It is thus a good demonstration of “Rechinger’s line”, the biogeographical borderline between Europe and Asia in the Aegean region.
