|discussion=<p><i>Euphorbia velleriflora</i> is native and widespread from northern Mexico to Guatemala. The species is apparently a recent introduction in southern Texas (W. R. Carr and M. H. Mayfield 1993), as the first records are from the 1990s. It is also expected in southern Arizona due to the presence of collections made a few kilometers south of the border in the Mexican state of Sonora. <i>Euphorbia velleriflora</i> is very similar to <i>E. stictospora</i>, and the two are sometimes confused. The two can be readily distinguished on the basis of their styles: unbranched in <i>E. stictospora</i> and 2-fid in <i>E. velleriflora</i>. Also, the involucral gland appendages of <i>E. velleriflora</i> are ciliate with short hairs, whereas those of <i>E. stictospora</i> are glabrous.</p>
