Abstract

Daucus traditionally has been estimated to contain 21-25 species, but a recent study expanded the genus to contain about 40 species. The present study uses ten nuclear orthologs to study 40 new collections including newly examined species of Daucus s.l.: D. arcanus, D. durieua, D. gracilis, D. montanus, D. setifolius, Melanoselinum decipiens, Monizia edulis, Pseudorlaya minuscula, Pseudorlaya pumila, Tornabenea annua, and T. tenuissima. As in prior studies, Daucus resolves into two well-defined clades A and B. The newly examined taxa resolve in clade B as D. arcanus sister to D. pusillus and D. durieua sister to D. glochidiatus. In clade A, D. gracilis, Tornabenea annua, and T. tenuissima resolve in a clade of 18-chromosome species with D. carota; Melanoselinum decipiens, Monizia edulis, Pseudorlaya minuscula, and Pseudorlaya pumila (along with previously examined Rouya polygama) are sister to the 18-chromosome clade; and D. setifolius sister to D. crinitus. Daucus montanus (hexaploid) is an apparent allopolyploid between D. pusillus (diploid) and D. glochidiatus (tetraploid). We propose the new combination Daucus junceus (Durieua juncea) for a neglected species endemic to SW Iberian Peninsula often referred to as D. setifolius, and place D. arcanus in synonymy with D. pusillus. Two lectotypes are also designated.
