|discussion=<p>No known morphologic character supports the taxonomic recognition of infraspecific taxa within <i>Pediocactus nigrispinus</i>. Characteristics used to distinguish the three described subspecies almost completely overlap. <i>Pediocactus nigrispinus</i> has been referred to <i>P. simpsonii</i> <i></i>var.<i> robustior</i> (J. M. Coulter) L. D. Benson, which remains well within the range of variation for <i>P. simpsonii</i>. An unpublished study by J. M. Porter et al. of noncoding chloroplast DNA sequences shows <i>P. simpsonii</i> is less closely related to P. nigripsinus than to <i>P. knowltonii</i>, <i>P. winkleri</i>, and <i>P. despainii</i>.</p>
