|discussion=<p>All material of <i>Petrorhagia dubia</i> from California, where it appears to be have been introduced in the Sierra <i>Nevada</i> foothills in the 1920s, and one population from northeastern Texas, have stipitate-glandular internodes. The presence of glabrous internodes in the Louisiana, Mississippi, Oklahoma, and most Texas populations (where it was first seen along roadsides in 1967) led to early confusion with <i>P. prolifera</i>. This suggests that these populations were derived from seed that came from Italy or Sicily, the only area in the native range where plants with glabrous stems are known. Roadside planting of either Italian rye grass [<i>Lolium perenne</i> Linnaeus var. italicum (A. Braun) Parnell] or crimson clover (Trifolium incarnatum Linnaeus) in Texas is the likely source of <i>P. dubia</i> in that region.</p>
