The Euro+Med treatment ofAstereae (Compositae)— generic concepts and required new names

Greuter, W.: The Euro Med treatment of Astereae (Compositae) — generic concepts and required new names. — Willdenowia 33: 45–47. 2003. — ISSN 0511-9618; © 2003 BGBM Berlin-Dahlem.A synonymic survey of Astereae 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 Erigeron, Eurybia, Galatella, Symphyotrichum and Tripolium, but do not so far exist, are validated. In one case (Erigeron alpinus subsp. intermedius) the validity of a previous combination, even though it was rather irregularly proposed, is confirmed.
