|discussion=<p>The taxon sometimes treated as <i>Arabis</i> laevigata var. missouriensis is here recognized as a separate species (<i>Boechera missouriensis</i>) based on its significantly longer petals (5–10 versus 3–5 mm) and distinctive, lyrate-pinnatifid basal leaves that persist well beyond anthesis.</p>
