|discussion=<p>The Texas populations and some of the northern Mexican populations consistantly have 3 stamens. These populations have been separated as <i>Juncus nodosus</i> <i></i>var.<i> meridionalis</i>. Plants with 3 stamens are found elsewhere, however, and other significant characters do not appear to separate these populations.</p>
