Abstract
In this study, the cypsela morphology of 21 (14 species) of the 28 (17 species) Turkish Cirsium Mill. sect. Cirsium (Asteraceae) taxa was examined by stereomicroscope and scanning electron microscope (SEM). The shapes of cypselas are oblong, obovate, narrowly obovate and oblanceolate. The taxa were divided into 7 main types according to the results of SEM investigation on cypsela surface characteristics as: scalariform, ribbed, scrobiculate-ribbed, scrobiculate, scrobiculate-reticulate, reticulate and bireticulate. Taxonomic significance of cypsela morphology is discussed. It is shown that cypsela features can be used as distinguishing characteristics in some Cirsium sect. Cirsium species.
