|discussion=<p><i>Avena fatua</i> is native to Europe and central Asia. It is known as a weed in most temperate regions of the world; it is considered a noxious weed in some parts of Canada and the United States.</p><!--
--><p><i>Avena fatua</i> is sometimes confused with <i>A. occidentalis</i>, but differs in having shorter, wider spikelets, fewer florets, and a distal floret which does not have a heart-shaped disarticulation scar. Hybrids between <i>A. fatua</i> and <i>A. sativa</i> are common in plantings of cultivated oats. The hybrids resemble <i>A. sativa</i>, but differ in having the fatua-type lodicule; some also have a weak awn on the first lemma. They are easily confused with fatuoid forms of <i>A. sativa</i>.</p>
