dc.description.abstractGeneric delimitations within the cosmopolitanCarduus-Cirsiumgroup (i.e., thistles) have a long history of taxonomic confusion and debate. We present the most comprehensive molecular phylogeny of the group to date to test generic limits, reconstruct the evolution of pappus type, and elucidate the role of chromosomal evolution. We offer two solutions for the recognition of monophyletic genera: (1) consolidate all taxa into one large genus (CarduusorCirsium), or (2) recognize each major clade as a genus (Carduus,Cirsium,Eriolepis,Notobasis,Picnomon,Silybum, andTyrimnus). Under the second proposal, the cryptic genusEriolepisis segregated fromCirsium, and the AfricanCarduusare included withinCirsium. The best diagnosable morphological character to delimit the genera is pollen type, which is not practical in field-based application. We caution that prior to implementing either solution, a thorough, comprehensive morphological analysis of all current members ofCirsiumsect.Epitrachys(= genusEriolepis) be completed. Future morphological studies may find additional achene or leaf surface characters that could be used for practical field identification of the segregate genera. The data show that the plumose pappus state is symplesiomorphic for the group, with one transition to barbellate pappus, likely followed by a reversal to its ancestral state as the group colonized Eurasia. The data are consistent with a North African origin in the region of the Mediterranean and a single colonization event to North America. An ancestral chromosome state ofn= 17 is hypothesized for the group, and a descending dysploidy series inCarduusis hypothesized to correspond with the aridification of the Mediterranean region. TheCarduus-Cirsiumgroup highlights the difficulty of delimiting morphologically similar, cryptic genera.en_US

dc.description.sponsorshipThis manuscript is dedicated to first author Jennifer Ackerfield's NMNH Smithsonian Institution advisor, Dr. Vicki Funk. Her mentorship, guidance, and unending support made this work possible. Her untimely passing has left a hole in our hearts as well as the botanical community. We thank Carol Kelloff and Gabriel Johnson (NMNH, Smithsonian Institution, Washington, D.C.) for their valuable laboratory and technical assistance. We thank Mark Simmons (Colorado State University, Fort Collins, Colorado) for assisting with the initial stages of phylogenetic analysis and providing insightful comments and discussion of the manuscript. First author Jennifer Ackerfield would like to thank Alfonso Susanna (Botanic Institute of Barcelona, Spain) for his advice, patience, and unending encouragement, and Kenneth Wurdack (NMNH, Smithsonian Institution, Washington, D.C.) for assistance taking achene photographs.
