|discussion=<p>Plants in south Florida and Cuba often have longer and narrower leaf blades than is typical, and G. O. K. Malme (1925) named Cuban material <i>Xyris</i> intermedia on the basis of longer, narrower leaf blades and entire sepal keels. In Florida, however, all of these characters intergrade. The red sepal tips, almost a homology with the bract dorsal area, are a constant (yet neglected) character. This species is often weedy.</p>
