Editing Arctium (section)

==Taxonomy==
A large number of species have been placed in genus ''Arctium'' at one time or another, but most of them are now classified in the related genus ''[[Cousinia]]''. The precise limits between ''Arctium'' and ''Cousinia'' are hard to define; there is an exact relation between their molecular [[phylogeny]]. The burdocks are sometimes confused with the cockleburs (genus ''[[Xanthium]]'') and [[rhubarb]] (genus ''Rheum'').
