Reinstatement of the Genus Macledium Cass. (Asteraceae, Mutisieae): Morphological and Phylogenetic Arguments

Studies of the genus Dicoma Cass. (Asteraceae, tribe Mutisieae) indicate that this taxon as currently defined is paraphyletic, and in fact comprises three groups showing marked morphological and anatomical differences. One of these groups is differentiated from Dicoma s.str. by a large number of cha...racters relating to morphology and anatomy of phyllaries, corolla, anthers, style, cypsela, and testa. It is proposed that these species should be considered as a separate genus, for which the name Macledium Cass. has nomenclatural priority. A brief nomenclatural synopsis is presented, including synonyms and nomenclatural types for each taxon in this genus of 20 species. Ausführliche Beschreibung Beschreibung ausblenden
