  • A new variety of Elsholtzia splendens (Lamiaceae) was found by the roadside of a mountain base at Jungmun-dong, Seogwipo-si, Jeju-do. The new taxon is termed Elsholtzia splendens var. fasciflora N.S. Lee, M.S. Chung & C.S. Lee, var. nov. The Korean name 'Da-bal-kkot-hyang-yu' was given. The morphological characters and illustrations of the species based on the holotype are provided together with a photograph of the habitat. It is distinctly distinguished from Elsholtzia splendens var. splendens by a few characteristics: leaves that area 2-4 cm long, leaves beneath the inflorescence, typically mostly 4; and inflorescence mosyly 2-4, fascicled, involucres oval.

  • Elsholtzia hallasanensis, E. springia, and E. splendens var. fasciflora (Lamiaceae) were reported recently as new species or new varieties of E. splendens according to their morphological characteristics. To reappraise the taxonomic status of these additional taxa and to determine the relationships between all Korean Elsholtzia taxa except E. saxatilis, which is distributed in North Korea, molecular studies based on the nrDNA (ITS) and cpDNA (rpl16, and trnH-psbA) sequences of seven taxa of Elsholtzia and one outgroup were carried out. The molecular data support that E. angustifolia and E. minima are distinct species from E. splendens and E. ciliata, respectively, because they have several private marker genes and show monophyly. The molecular data also support that E. splendens has a very close taxonomic relationship with both E. hallasanensis and E. springia. We found that E. splendens var. fasciflora, with multiple inflorescence, was based on several private marker genes and on the monophyly of its trees, suggesting that it can be considered as a variety. Elsholtzia springia, with the same sequences and the same morphological characteristics with E. hallasanensis after transplanting, should be treated as a synonym of E. hallasanensis. Moreover, we consider the taxonomic status of E. hallasanensis as E. splendens var. hallasanensis (Y. Lee) N.S. Lee & C.S. Lee, stat. nov.
