|discussion=<p>As treated here, <i>Zigadenus densus</i> includes Z. leimanthoides (W. W. McDearman 1984). These two entities are distinct in some parts of the range, but intergrade in size, inflorescence morphology, and flowering time in the Gulf coast region. The size of the plant (determined by age and environment) seems to affect inflorecence morphology, smaller plants bearing simple racemes and larger plants developing compound ones. Plants in more mountainous habitats develop paniculate inflorescences. Recognition of the two taxa at the varietal level may eventually be desirable.</p>
