|discussion=<p><i>Hirschfeldia incana</i> was first collected in North America in 1895 in the San Bernardino region, and by 1936 it was described as “already a serious agricultural pest, spreading freely over dry, unbroken ground and flourishing chiefly during the arid summer season” (W. L. Jepson 1909–1943, vol. 2).</p><!--
--><p><i>Hirschfeldia incana</i> can be confused with <i>Brassica nigra</i> because both have fruits appressed to the rachis. The former is distinguished from the latter by its distinctly shorter fruit, seeded and often swollen beak, and smaller petals.</p>
