) as Endangered (EN). The total number of fertile individuals in the two localities was estimated to range between 50 and 100. While the population of Mt. Sobo is located in the protected area of the Sobo Katamuki National (Kokutei) Park, the population occurring in Mt. Karasu-dake is not protected. It grows on steep rocky cliffs and the localities are not commonly known, and thus the populations appear stable. However, the formal description of this species may increase the collection pressure. Protection measures are currently being planned with administration.
