This is the wild rose with the smallest leaves and flowers in Japan: the size of flowers is ca. 1.5 cm, and its peduncle and calyx are normally villous. Usually 2 to 5 flowers make small panicles. The hips are small and almost globular, 5 to 6 mm across. A local variation of this rose in Shikoku bears particularly small flowers. Its long terminal leaflet is another feature of this rose.
