|discussion=<p>Of the five varieties of <i>Lepidium alyssoides</i> recognized by R. C. Rollins (1993), one (<i></i>var.<i> mexicanum</i> Rollins) is a short-tufted form of the species restricted to Mexico that does not seem to merit recognition, another (var. junceum) is a glabrescent form of the type variety, a third (<i></i>var.<i> eastwoodiae</i>) is treated below as a distinct species, and the fourth (var. angustifolium) is included here within <i>L. alyssoides</i>.</p>
