Özet

The pollen morphological structures of Turkish endemic species of Centaurea armena Boiss., C. aucherana D. C., C. pyrrhoblephara Boiss., C. fenzlii Reichardt., C. hermannii F. Hermann., C. kilaea Boiss., C. kurdica Reichardt., C. tchihatcheffii Fisch and Mey. have been studied in detail by means of light (LM) and transmission (TEM) microscopes for the first time. LM examinations show that the pollen grains of eight taxa are more or less spheroidal - subprolate, tricolporate, tectate - perforate, microechinate - scabrate, amb triangular and the Jacea-type is dominant. On the basis of their exine ultrastructure C. pyrrhoblephara, C. tchihatcheffii and C. aucherana seem to resemble the Anthermoid-type, but the other five taxa resemble the Helianthoid-type.
