Phylogenomics and morphological evolution of the mega-diverse genus Artemisia (Anthemideae, Asteraceae): Implications for its circumscription and infrageneric taxonomy.

The circumscription of Artemisia is enlarged to include the genus Kaschgaria. The morphological characters traditionally used for the infrageneric taxonomy of Artemisia do not match the new phylogenetic tree. They experienced more complex evolutionary history than previously thought. We propose a revised infrageneric taxonomy of the newly circumscribed Artemisia with eight recognized subgenera to accommodate the new results.
