|discussion=<p>Morphological evidence suggests that <i>Boechera grahamii</i> is an apomictic species that arose through hybridization between <i>B. collinsii</i> and <i>B. stricta</i>. Previous authors have assigned these specimens to <i>Arabis</i> (<i>Boechera</i>) divaricarpa (see M. D. Windham and I. A. Al-Shehbaz 2007b for detailed comparison); if these taxa are treated as conspecific, the name <i>B. grahamii</i> has priority.</p>
