Discussion
Tragus racemosus is native from the Mediterranean region to southwest Asia, but now grows in the United States, primarily in Cochise and Pima Counties, Arizona. It was collected in Maine, Pennsylvania, New York, and North Carolina in the late nineteenth century, but does not appear to be established in these states. Reports for New Mexico and Texas appear to reflect confusion with T. berteronianus.
