|discussion=<p>Along the interface of the distributions of <i>Melampodium cinereum</i> and <i>M. leucanthum</i>, some plants are intermediate for traits used to characterize the two species; perhaps the two should be treated as one.</p><!--
--><p>Plants of <i>Melampodium cinereum</i> with leaf blades linear-oblong and basally strigose with hairs 0.3–0.6 mm have been treated as var. cinereum, plants with leaf blades linear-oblong and basally strigose with hairs 0.6–1.5 mm as var. hirtellum, and plants with leaf blades linear and basally strigose with hairs 0.3–0.6 mm as <i></i>var.<i> ramosissimum</i> (T. F. Stuessy 1972).</p>
