|discussion=<p>Of conservation concern.</p><!--
--><p>Coryphantha nickelsiae in the flora is based on old herbarium specimens labeled only as from “Laredo, Texas.” Coryphantha nickelsiae belongs to the same species group as C. ramillosa. Coryphantha sulcata, with which L. D. Benson (1969b, 1969c, 1982) inexplicably united C. nickelsiae, is not closely related.</p><!--
--><p>Coryphantha nickelsiae often has ribbonlike uppermost radial spines.</p>
