Hieracium fallax – discharge of a familiar name

Abstract

During the 19th century the taxonomical circumscription and interpretation of H. fallax was very unclear and inconsistent. Especially since the monograph of Nägeli & Peter (1885) it has undergone a strong transformation which no longer concurs with the description in Willdenow (1809) and the type material in B. This paper outlines the history of this change of meaning. In consideration of the splitting of Hieracium s. l. in Hieracium s. str. and Pilosella, a change of name and a new combination into Pilosella cymosiformis is necessary. Lectotypifications of H. cymosiforme, H. fallax and P. setigera are made.
