[1/2] M. sinensis community is considered to be one of the last stages of grassland in Japan. This plant establishes with tree species on skislopes in Hokkaido, and may be a keystone species to restore the plant communities on the skislopes (Tsuyuzaki 2005). For Japanese culture, this species is very important to enjoy the moonlight in autumn. In early October 16 1983.
