Lolium rigidum is a species of annual grass. Common names by which it is known include annual ryegrass, a name also given to Italian ryegrass (Lolium multiflorum), rigid ryegrass, stiff darnel, Swiss ryegrass and Wimmera ryegrass.[1] It is a native of southern Europe, northern Africa, the Middle East and the Indian subcontinent and is grown as a forage crop, particularly in Australia, where it is also a serious and economically damaging crop weed.
