|discussion=<p>Flowers of <i>Platanthera purpurascens</i> are strongly semen scented, and their musty scent is markedly different than the sweet and spicy scents of other fragrant species.</p><!--
--><p>In some areas this species hybridizes with <i>Platanthera dilatata </i>var.<i> albiflora</i>, producing sweetly fragant plants with lanceolate green lips. At the southern edge of its range, however, it often occurs with similar plants in the absence of another putative parent. The identity of these plants is uncertain. Their rather generalized morphology might mask polyphyletic origins.</p>
