| The taxonomic status of Ligusticum tenuissimum (Nakai) Kitagawa and Libanotis coreana (Wolff) Kitagawa has been controversial in Korea. We examined their phylogenetic relationships by comparing the internal transcribed spacer (=ITS) sequences of the nuclear ribosomal RNA gene (=rDNA) with another seven species in the Korean Umbelliferae. Our results support the legitimacy of the nomenclatural combination with L. tenuissimum Kitagawa rather than with Angelica tenuissima Nakai. We also suggest using L. coreana (Wolff) Kitagawa instead of Seseli coreanum Wolff because L. coreana has been completely separated from most taxa of the genus Seseli. In addition, we have confirmed at least three phylogenetic lines in the genus Ligusticum. One is the core group of Lisusticum that comprises L. tenuissimum and four other species. This clade includes the Ligusticum hultenii line and Ligusticum scothicum, known as an anomaly of Ligusticum. The second clade is composed of Ligusticum physospermifolium with Seseli monatum, which indicates the polyphyly of Ligusticum. The third line is Ligusticum acutilobum, clustered as a sister grade of Dystaenia. |
