|discussion=<p>R. D. Dorn (2000) justified treating <i>Salix jepsonii</i> as <i>S. sitchensis</i> <i></i>var.<i> angustifolia</i> based on specimens of <i>S. jepsonii</i> from southern Oregon. <i>Salix jepsonii</i> does occur in southern Oregon but is distinct enough from <i>S. sitchensis</i> to be treated as a species.</p>
