Greuter, W.: The Euro Med treatment of Cardueae (Compositae) — generic concepts and required new names. — Willdenowia 33: 49–61. 2003. — ISSN 0511-9618.A synonymic survey of Cardueae genera accepted for the purpose of the Euro Med Project is presented. As a consequence of shifts in generic circumscription, or reassessment of accepted specific and subspecific taxa, combinations that are required in the genera Amphoricarpos, Carduus, Carlina, Carthamus, Centaurea, Cyanus, Echinops, Jurinea, Klasea, Psephellus, Rhaponticoides, Rhaponticum and Volutaria, but do not so far exist, are validated. Three names in Centaurea, two of them Linnaean, are typified.
