|discussion=<p>In most populations of Asarum caudatum, the distal portion of the sepal is spreading or weakly reflexed and 30-75 mm. A single population south of Mt. Shasta, California, has the distal sepals strongly reflexed and unusually short, often as little as 1.1 cm. Flowers of these plants superficially resemble those of A. lemmonii; they differ in being horizontal, not descending as in A. lemmonii, and in the filiform-attenuate sepals.</p><!--
--><p>Native Americans used Asarum caudatum medicinally to treat headaches, intestinal pain, knee pain, indigestion, boils, tuberculosis, and colic, and as a general tonic (D. E. Moerman 1986).</p>
