|discussion=<p>K. M. Stocking (1955b) enlarged <i>Marah macrocarpa</i> to include <i>M. micrantha</i> Dunn [as <i>M. macrocarpa</i> <i></i>var.<i> micrantha</i> (Dunn) Stocking], which is known only from</p><!--
--><p>Cedros Island off the Pacific coast of Baja California, outside of Vizcaíno Bay. But the relatively small flowers and seeds of the latter [staminate flowers 3–6(–8) mm diam. versus 8–13 mm diam.; seeds 12–13 mm versus 15–20 mm] and its apparent geographical disjunction suggest that treatment of <i>M. micrantha</i> at specific rank is justified.</p>
