|discussion=<p>Of conservation concern.</p><!--
--><p>Pediocactus winkleri (and P. despainii) were recently combined with P. bradyi. Analyses of chloroplast DNA sequences (J. M. Porter et al. unpubl.), however, provide strong evidence of a close relationship among P. winkleri, P. despainii, and P. simpsonii, not P. bradyi. By contrast, P. bradyi is more closely related to P. sileri and P. peeblesianus. The morphologic distinction between P. winkleri and P. despainii is much more tenuous than the key and descriptions indicate (see comments under 9. P. despainii).</p><!--
--><p>Pediocactus winkleri is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
