    Centaurea yaltirikii sp nov (Asteraceae, C. sect. Pseudoseridia) from Turkey
    (Wiley, 2008) Aksoy, Necmi; Duman, Hayri; Efe, Asuman
    A new species of Centaurea L. (Asteraeeae) from Turkey is described and illustrated. Centaurea yaltirikii N. Aksoy, H. Duman & A. Efe sp. nov. (C. sect. Pseudoseridia Wagenitz) is restricted to the rocky slopes of Elmacik Dagi (A3: Duzce-Golyaka). It is morphologically most similar to C. drabifolioides Hub.-Mor. and C. cheirolepidoides Wagenitz, but differs in stem, leaves and phyllary appendange characters. The diagnostic morphological characters are discussed. The habitat and conservation status of the species are presented, and the geographical distribution of the new species and other related species is given.
