Rock fan - Rock fan

An evergreen perennial plant of the family Atractylodes (APG classification: Atractylodes family). The leaves, which grow in clusters at the ends of thin creeping stems, are leathery, broadly round or round with concave tips. In spring, a flower stalk extends from the leaf axil and produces a single red-purple flower. The flower is bell-shaped with five lobes, the lobes of which are further divided into smaller pieces. It has five stamens and five pseudostamens. It grows in dark mountainous areas and is found only on Honshu. The closely related Ryukyu Iwauchiwa, also known as Shimai Iwauchiwa, is found south of Amami Oshima and in Taiwan, and has white flowers. There is also one species each in North America and China in this genus.
