Prunella vulgaris var. lilacina Nakai, P. vulgaris var. aleutica Fernald, and P. vulgaris var. albiflora Nakai have been reported as infrageneric taxa of Prunella L. in Korea. I found many samples of P. pinnatifida Pers. in the previously collected herbarium sheets in several major herbaria in Korea and confirmed its distribution again in Jaeun Island, Chonnam Province with the information from those herbarium sheets. P. pinnatifida Pers. has deeply lobed leaves in contrast to entire or barely dentate leaves of P. vulgaris var. lilacina Nakai, P. vulgaris var. aleutica Fernald, and P. vulgaris var. albiflora Nakai. I first report the distribution of this taxon in Korea and give it the Korean name Gal-re-kkul-pul. I provide description, illustrations, and an infrageneric key to identification of the other taxa of Prunella in Korea, and discuss some taxonomic problems of this taxon.

Five taxa of the genus Ajuga L. (Lamiaceae) were known previously in Korea which were mainly distributed in lowland and lower montane areas at 50-1000 m elevation. We report an unrecorded taxon of the genus Ajuga in Korea, namely Ajuga nipponensis Makino. This taxon was discovered at Is. Nok, Boryeong-si, in Chungcheongnam Province. A. nipponensis is found to be distributed along roadsides near villages of the island. A. nipponensis was distinguishable from other Ajuga in Korea by following combination of characters: Stems erect or procumbent, arranged in a dense cluster, corolla whitish-pale pink, 10-12 mm long. This taxon was named 'Bun-hong-kkot-jo-gae-na-mul' in Korean based on color of the corolla. The key to the genus Ajuga in Korea is also provided.
