|discussion=<p><i>Aegilops cylindrica</i> is a widespread weed in North America, being particularly troublesome in winter wheat. It usually grows in disturbed sites, such as roadsides, fields, and along railroad tracks. It is native to the Mediterranean region and central Asia, and is adventive in other temperate countries. Its apparent absence from Canada is somewhat remarkable.</p><!--
--><p>Hybrids between <i>Aegilops cylindrica</i> and <i>Triticum aestivum</i>, called xAegilotriticum sancti-andreae (Degen) Soo [p. 266], have been found in various parts of North America. They often have a few functional seeds which, on maturing into reproductive plants, can backcross to either parent. For this reason, <i>A. cylindrica</i> is considered a serious weed in many wheat-growing areas within the Flora region.</p>
