It is a native of the Mediterranean region, but is now widely distributed over grain-growing coun- tries, and with the closely related J. harhata Brot. is especially common in Cal- ifornia and Oregon, and has spread eastward to Minnesota. It is of rare occurrence in the Eastern States. By some this is 8ui)posed to be the original of the cultivated oat (Avena satira), which is said to readily degenerate into it. Avena fatua is in most places regarded as a troublesome weed. When abundant in the grain fields, it occupies the place of better plants, and reduces the of the thrashed grain by the admixture of its inferior and lighter seeds. The stiff and twisted awns are injurious to stock, as they freijuently cause irritation of the nostrils and mouths of the cattle feeding upon them. In California the young plants, before the bearded or awned spike- lets mature, are esteemed for grazing and forage. "The use of the Wild-oat, with its brown, hairy seed and twisted awn, as an artificial fly by fishermen, is well known, the uncoiling of the awn when, wetted causing those contortions by which it imitates a fly in ; (Hooker.)
