A new species, Acantholimon evrenii sp. nov. is described and illustrated for the first time in sect. Glumaria from Turkey. The species is confined to B7 Elazig in East Anatolia where it grows on rocky mountain steppes. The diagnostic morphological characters from closely related species are given, along with a discussion dealing with its taxonomic relationship. Its conservation status is indicated. A revised key is also provided for the Acantholimon species with heterophyllous leaves, two or more flowered and four or more bracteated spikelets. (c) 2005 The Linnean Society of London.
