We investigated the phylogeny of the Arctioid lineage of the Arctium-Cousiniacomplex in an attempt to clarify the conflictive generic boundaries of Arctium and Cousinia. The study was based on analyses of one nuclear (ITS) and two chloroplastic (trnL-trnT-rps4, rpl32-trnL) DNA regions of 37 species and was complemented with morphological evidence where possible. Based on the results, a broadly redefined monophyletic genus Arctiumis proposed. The subgenera Hypacanthodesand Cynaroidesare not monophyletic and are suppressed. In contrast, the traditional sectional classification of the genus Cousiniais maintained. The genera Anura, Hypacanthiumand Schmalhauseniaare reduced to sectional level. |
