REMARKS Fifteen herbarium specimens of the type of Echinops ceratophorus were found at FI, G, H, K, L, MO, P, W, and WAG, which have to be treated as syntypes (art. 40 note 1 of Turland et al. 2018 ). According to McNeill (2014) , the existence of a holotype cannot be established in this case because there was more than one specimen for this species, housed in more than one institution. The specimen G00765429 is selected here as the lectotype, because it clearly shows the characters mentioned in the protologue. Rechinger (1950) described Echinops farsicus as a new species from Kuh Tschah Siah (Fars Province) for Iran. Twenty nine years later, Rechinger (1979) placed E. farsicus to synonymy of E. ceratophorus . As no morphological differences between both species can be seen, Rechinger’s treatment is followed here.
