|discussion=<p>The range of <i></i>var.<i> planitierum</i> is centered on the Texas Panhandle; it does not overlap with those of other members of the <i>Glossopetalon spinescens</i> complex. M. R. Ensign (1942) noted an unusual collection from near the Louisiana border in Marion County, Texas (Harris 470, US). This disjunct occurrence, upon which Ensign equivocated, would extend the distribution of the taxon significantly eastward and significantly lower its elevational limit (and that of the entire genus) to about 50 m. Plants have not been rediscovered in eastern Texas since 1930.</p>
