|discussion=<p>Plants of <i></i>var.<i> purshii</i> were placed by G. B. Rossbach (1958) in three species (<i>Erysimum</i> angustatum, <i>E. argillosum</i>, <i>E. desertorum</i>) and by R. C. Rollins (1993) in two species (E. angustatum, <i>E. capitatum</i>). The considerable overlap in morphology and the frequent hybridization between vars. capitatum and purshii in areas where their geographical ranges meet argue against such delimitation. Forms with linear leaves to 3 mm wide, which are restricted to eastern Alaska and western Yukon, were recognized by Rossbach and Rollins as E. angustatum, but these hardly differ from typical <i></i>var.<i> purshii</i> in all other characters.</p>
