ABSTRACT
Phylogenetic study of Dystaenia which consisted of two species, D. takesimana from Korea and D. ibukiensis from Japan, was hampered because of its isolated distribution and relatively recent description. In this study, the phylogenetic position of two species of Dystaenia in the tribe Apieae of subfamily Apioideae (family Apiaceae) was examined using ITS sequence of nuclear rDNA. The ITS sequences data indicate that Dystaenia is a monophyletic group which is most closely related to Endressia and Seseli. However phylogenetic affinity of Dystaenia with two taxonomically related genera, Angelica and Ligusticum, was not observed. Relatively high sequence divergence value between D. ibukiensis and D. takesimana implies that they are all distinct species.
