Özet
The pollen morphology of eight endemic species of the genusInulaL. (Asteraceae) -I. heleniumsubsp.orgyalis(Boiss.) Grierson,I. heleniumsubsp.vanensisGrierson,I. macrocephalaBoiss. & Kotschy ex Boiss.,I. discoideaBoiss.,I. saranaBoiss.,I. fragilisBoiss. & Hausskn.,I. anatolicaBoiss. andI. sechmeniiHartvig & Strid - distributed in Turkey was studied with light microscopy and scanning electron microscopy. We found that the pollen of theseInulataxa are prolate-spheroidal in shape (except inInula discoidea), with the polar axis ranging from 19.18 to 33.14 mu m and the equatorial diameter ranging from 18.54 to 32.92 mu m. The pollen grains are tricolporate and their ornamentation is echinate. The exine thickness ranges from 0.87 to 2.07 mu m. As this study demonstrates, results of Principal Component Analysis are revealed that some of the pollen characters, such as spine length and width, are significant morphological characters for taxonomic discrimination of the eight endemicInulataxa. According to cluster analysis, two main groups of examined taxa are constituted.
