|discussion=<p>The distinctions between <i>Argyrochosma dealbata</i> and <i>A. limitanea</i> are subtle but apparently absolute. Although both occur in Texas, their ranges do not overlap. Despite the morphologic similarities, isozyme analyses indicate that <i>A. dealbata</i>, a diploid species, was not involved in the origin of polyploid <i>A. limitanea</i>.</p>
