abstract = {In a previous study using 94 nuclear orthologs, we reported the species status of D. broteri and D. guttatus (here referred to as the D. guttatus complex) to be unresolved, partitioned into three clades. In the present study, a subset of ten of these 94 nuclear orthologs with 10,982 bp of aligned length was used to infer the phylogeny of 83 accessions of 15 species and three subspecies of Daucus, with a focus on the D. guttatus complex. A near parallel set of accessions were used for morphological analyses of germplasm accessions planted in a common garden in Madison, Wisconsin. The molecular trees are highly resolved for most of the external and many of the internal clades, grouping accessions of the D. guttatus complex into four clades. Bayesian concordance analysis and coalescent (species tree) approach gave a slightly different topology. Morphological data likewise support four taxa of accessions previously identified as D. broteri and D. guttatus. With historical and herbarium research from a companion study, we identify these four clades as D. guttatus, D. setulosus, D. conchitae, and D. bicolor; internested in these segregates are the phenetically distinctive species D. glochidiatus, D. involucratus, D. littoralis, and D. pusillus. Our research redefines species variation in the D. guttatus complex, clarifies species names, interspecific relationships, and discovered misidentifications in germplasm collections. It confirms a new useful subset of nuclear orthologs for studies of dominant topologies of Daucus and morphological characters useful to identify these four species.}
