  • The morphological characters and scientific names of Korean Artemisia sect. Absinthium were reviewed based on the type specimen, the original description, observation of the living materials and voucher specimens. The form of the habitat, the structure of underground, the leaf shape and capitulum features were valuable characters in identifying the taxa. The sect. Absinthium in Korea was classified as three taxa of A. sieversiana, A. lagocephala, A. fauriei. The illustration and description of each taxa were provided. Particularly, A. fauriei in this section with hair on receptacle and A. fukudo in sect. Abrotanum without hair on receptacle grow in mixed groups on the West shore of Korea. Two species with populations which grow in mixed groups, was observed as being putative hybrid individuals based on morphological characters.

  • This study was intended to investigate the capitulum morphology and to evaluate its taxonomic importance within the 23 taxa of Korean Artemisia L. The Korean Artemisia was classified into sterile subg. Dracunculus and fertile subg. Artemisia by the fertility of the disk florets, which is the traditional diagnostic character of subgenera. There are sections in subg. Artemisia: sect. Absinthium with a densely, sparsely hairy receptacle, and sect. Abrotanum and sect. Artemisia with a glabrous receptacle. However, A. fukudo and A. sacrorum belonging to sect. Abrotanum, and A. viridissima belonging to sect. Artemisia were observed to have sparsely hairy receptacles. Therefore, the presence of hair on a receptacle, which is now regarded as a key character distinguishing sections, has to be reevaluated. The whole shape and size of the capitulum, the characteristic of the stigma apex, the hair on the involucral bract, and the shape of the central or peripheral floret are thought to be the most valuable characters to consider in recognizing species.
