Craniospermum is a genus of flowering plants in the family Boraginaceae, native to Kazakhstan, the Altai, Siberia (Buryatiya, Irkutsk, Tuva), Mongolia, and Xinjiang and Inner Mongolia in China.[2] They are tuft-forming biennial or perennial herbs, and are generally highly endemic, thought to be relicts of the hypothesized ancient Mediterranean flora.[3][4]
