"Chokai-azami" (Cirsium chokaiense) belongs to Asteraceae (the Aster family). it is a perennial herb that is endemic to Japan and is distributed on Mt. Chokai, which straddles Akita and Yamagata prefectures in Honshu. It grows on open grasslands in the alpine zone and can reach 50-150 cm in height. There are also basal leaves at the time of flowering, and the cauline leaves hold the stems. Around August, the crimson flower heads bloom downward. It is similar to "Oni-azami", but the narrow tube of the corolla is almost the same length as the wide tube. The bracts are purple-black and sticky.
