Adenostyles Cass.
Adenostyles is a small genus of three species, native in Central- and southern Europe. One species, Adenostyles alliariae, was once recorded as an alien in Belgium. A revised key to the species and subspecies and a conspectus of the genus are presented by Dillenberger & Kadereit (2012).
