|discussion=<p>G. L. Nesom (2003) recognized <i>Xanthisma spinulosum</i> var. glaberrium at species level, as it occurs sympatrically with variety spinulosum in the Texas panhandle, where the two taxa behave like biological species; on the eastern plains of Colorado, however, hybridization and autoploidy have been documented (D. P. Hauber 1986).</p>
