“…This genus divided into three sections, viz Cephalonoplos (Neck.) DC., Cirsium, Epitrachys DC., is represented by 80 taxa in Turkey, according to recent studies (Davis and Parris 1975, Yıldız 2012, Yıldız et al 2013, Duman et al 2017.…”

Cirsium Miller, one of the largest genera of the Asteraceae (Carduoideae), contains more than 250 taxa. Turkey is one of its diversity centers and according to recent studies this genus is represented by 80 taxa. In the present study, cypsela morphologies, micromorphologies and anatomical structures of 17 C. sect. Epitrachys taxa distributed in Turkey are characterized in detail by using stereomicroscope, light microscope (LM) and scanning electron microscope (SEM). Cypselas are found to be obovate to narrowly oblong, or rarely oblanceolate. Based on SEM characters, six cypselas surface ornamentation types are identified, pericarp anatomical structures are described, as well as the structure of the testa. Crystal formations were observed in three taxa and secretory materials in the mesocarp were evaluated. Data obtained from this study are compared with previously published results and it is concluded that fruit micromorphological and anatomical characters are useful for the delimitation of taxa in Cirsium and may be useful for supraspecific classification.

This study evaluates the phylogenetic relationships of some Centaurea s.l. taxa native to Northeast Anatolia, Turkey. Stem, leaf and cypsela anatomical structures and cypsela micromorphologies were characterized and compared in detail by using variance analysis and cluster analysis (UPGMA). Macro and micromorphological characteristics of cypsela were investigated using a stereomicroscope and scanning electron microscope. Significant differences were observed in stem features, leaf midrib and lamina thickness, number of stomata, and epidermal cell wall patterns in the abaxial and adaxial surfaces among the taxa. Cypsela shapes were determined as ovoid or widely oblong. Cypselas can be distinguished into four types of surface ornamentations. The structure of the pericarp was described, as well as the testa, and the distribution of the sclerenchymatic zone of the ribs and secretory ducts (resin) in the mesocarp were evaluated.
