|discussion=<p><i>Bothriochloa ischaemum</i>. grows along roadsides and in waste ground and rangeland pastures, at 50-1200 m. It is native to southern Europe and Asia. It was introduced to the United States for erosion control along right of ways and for livestock forage in the southwest. It is now established in the region and has spread along roadsides into other central and southern states. There are two variants that are sometimes recognized as varieties, plants with glabrous nodes being called <i>B. ischaemum</i> var. ischaemum and plants with pubescent nodes being called <i>B. ischaemum</i> var. songarica (Rupr. ex Fisch. & C.A. Mey.) Celarier & J.R. Harlan. The varieties are not recognized here.</p>
