Özet
Fruit morphology and anatomy have taxonomic importance in Asteraceae. The fruits structures of Crepis from Turkey, which include five species (C. alpina, C. smyrnaea, C. pulchra, C. zacintha, C. sancta) and two subspecies (C. foetida subsp. foetida and C. foetida subsp. rhoeadifolia) were studied for fruit morphological and anatomical characters with oneway analysis of variance, cluster analysis and principal component analysis. Fruit size, shape, color, and the presence of beak were observed with stereomicroscopy. Whereas the surface patterns of fruit and pappus were examined using scanning electron microscopy (SEM). Furthermore, pericarp structure, thicknesses of testa and endosperm, and number of rib, cotyledon width in cypsela were studied anatomically. Results indicated that cypsela sizes, the presence or absence of beak on the cypsela, fruit and pappus surfaces, pericarp. Thickness of testa and endosperm, and number of ribs are of major importance to illustrate interspecific relations among the examined taxa. Also, this investigation is a preliminary study, which was performed to use fruit morphological and anatomical characters for their practicality on the classification of taxa within the genus.
