|discussion=<p>Species 13 (13 in the flora).</p><!--
--><p><i>Cordylanthus</i> is similar to <i>Orthocarpus</i> but differs in having spathelike calyces deeply cut along one side and narrowly lanceolate, entire bracteoles subtending each flower. Also, the abaxial lip of <i>Orthocarpus</i> is spreading; it usually is appressed to the adaxial lip in <i>Cordylanthus</i>. The mature flowers often appear to be buds.</p><!--
--><p><i>Cordylanthus</i> is sometimes defined to include <i>Dicranostegia</i> and <i>Chloropyron</i> as subgenera (T. I. Chuang and L. R. Heckard 1986). D. C. Tank et al. (2009) found that those genera are a sister group of <i>Triphysaria</i>. The monograph by Chuang and Heckard provided the basis for most of the species delineation presented here.</p>
