|discussion=<p>Herbarium specimens of <i>Viola quercetorum</i> and <i>V. purpurea </i>var.<i> purpurea</i> can be difficult to distinguish; pressing obliterates the undulate leaf margins of <i>V. quercetorum</i>. In Oregon, most collections of <i>V. quercetorum</i> are from yellow pine forests (A. Liston, pers. comm.).</p><!--
