|discussion=<p>Although originally described as a variety of <i>Draba</i> apiculata (= <i>D. globosa</i>), <i>D. daviesiae</i> is distinct morphologically. It is easily distinguished from the former by its densely pulvinate habit, obtuse leaf blades, and obscurely veined fruit valves. By contrast, <i>D. globosa</i> exhibits a cespitose but non-pulvinate habit, acute leaf blades, and prominently veined fruit valves. <i>Draba daviesiae</i> is known from the Bitterroot Mountains in Ravalli County.</p>
