|discussion=<p>Lewisia oppositifolia is known only from Del Norte County, California, and Josephine County, Oregon.</p><!--
--><p>The floral symmetry of Lewisia oppositifolia may be somewhat elliptical, the outer two petals alternating with the sepals and the remaining petals imbricate and opposite the sepals, giving the flowers a pinched appearance, a feature also reported for L. nevadensis. The more diminutive, higher-elevation plants of L. oppositifolia possibly represent a distinct taxon that has been informally recognized as “Lewisia richeyi” (B. Mathew 1989b).</p>
