The "Ezono-hakusan-ichige" (Anemone narcissiflora var. sachalinensis) belongs to Ranunculaceae (the Buttercup family). It is a perennial herb that is distributed from northern Honshu to Hokkaido in Japan and Sakhalin. It grows in subalpine to alpine grasslands, reaching heights of 15 to 40 cm. The stems and stipes are densely covered with coarse hairs. The basal leaves are trifoliate, nearly round, with further finely divided leaflets. From June to August, it produces 2 to 6 white flowers in a radiate pattern at the stem apex. What appear to be petals are actually sepals, numbering 5 to 6. The scape bears 4 cauline leaves in a whorl, without stipes. Differences from the Honshu-distributed species "Hakusan-ichige" include broader leaves without pointed tips and shorter peduncles.
