Plants belonging to the Genus Cirsium of the alpine zone in central Honshu, Japan, are taxonomically studied with special reference to the internal structure of glandular bodies of involucral scales. Cirsium fauriei NAKAI, which has been long treated as a synonym of C. nipponicum (MAXIM.) MAKINO var. incomptum (MAXIM.) KITAMURA, is restored as a distinct species. The name, C. fauriei, is the earliest legitimate name for the plants occurring in the alpine zone of central Honshu. It is also recognized that plants from Mts. Yatsugatake belong to a new species, C. yatsu-alpicola KADOTA et Y. AMANO, sp. nov. The C. fauriei group is endemic to the alpine zone of central Honshu and consists of the following four entities : C. fauriei NAKAI, C. otayae KITAMURA, C. senjoense KITAMURA and C. yatsu-alpicola KADOTA et Y. AMANO, sp. nov. These four species are keyed out.
