Abstract |
|
The taxonomy of umbel genus Sium L., Apiaceae in Korea was reviewed on the basis of molecular phylogenies derived from sequences of nuclear ribosomal DNA internal transcribed spacer (ITS) regions. The ITS sequence-derived phylogeny indicates that S. heterophyllum, endemic to Korea, is identical to S. tenue, which is known as endemic to Ussuri regions. Comparisons of sequence pairs across both spacer regions gave divergence values and revealed the identity between S. tenue and S. heterophyllum on Mt. Moonsoo. On the other hand, the ITS sequences support species delimitation of S. ternifolium, as reported recently as a new species that differs from other Sium species. The ITS sequence divergence values of 1.4 and 1.6% support species delimitation between S. serra and S. ternifolium. |
