It is a species with a relatively northern distribution in the genus Milium, and the northernmost can be distributed to the East Gobi, Middle Gobi and Junggar Gobi in Mongolia.In China, it is only recorded in Xinjiang and Hebei.Milium lineatum is an annual short lived herb with a height of only 8 cm. As a companion species in the community, it is not easy to be found by investigators.[2]
