The name Cirsium originates from the Greek word "khirsos", which means "swollen vein", referring to diseases of veins. Tournefort, citing Dioscorides, reported that the roots of this plant were used against diseases of veins. In addition, the use of this plant in varicose disease for pain relief was reported (Tournefort, 1694;Charadze, 1963). The name Cirsium was used by botanists in the pre-Linnean period (Bauhin, 1596; Tournefort, 1694). In Species Plantarum, the species of the genus Cirsium were treated given under the names of the genera of Serratula L., Carduus L., and Cnicus L. by Linnaeus (1753).The history of the genus Cirsium is given below chronologically in terms of taxonomy:The first comprehensive study was carried out in "Prodramus Sytematis Naturalis" by Candolle (1838). In this study, the genus was represented by 137 species belonging to 6 sections: C. sect. Lophiolepis Cass. (4 species), C. sect. Eriolepis Cass. (38 species), C. sect. Orthocentron Cass. (6 species), C. sect. Corynotrichum DC. (3 species), C. sect. Cephalonoplos (Necker) DC. (5 species), and C. sect. Onotrophe Cass. (81 species). In Flora Orientalis, 74 species belonging to 4 sections, C. sect. Epitrachys DC. ex Duby (38 species), C. sect. Chamaelon DC. (28 species), C. sect. Lamyra Cass. (7 species), and C. sect. Breea Less. (1 species), were given by Boissier (1875).Sommier and Levier (1895) reported 53 species (including the NE of Turkey) without separating them into sections in their work Cirsium del Caucaso.In addition, 111 species belonging to 16 subsections and 7 sections were given by Charadze (1963) in Flora of the USSR, 60 species belonging to 3 sections were given by Werner (1976) in Flora Europaea, and 36 species belonging to 7 subsections and 5 sections were given by Petrak (1979) in Flora Iranica.
