|discussion=<p>Coryphantha chaffeyi is nearly identical to C. dasyacantha and might yet prove to be conspecific. Coryphantha chaffeyi is distinguished only by the following characteristics: (1) flowers averaging smaller in all parts, as seen from living material; (2) spines whiter; (3) spines usually more numerous; and (4) populations confined to higher altitudes. Some populations (e.g., on limestone in the Del Norte Mountains and the Dead Horse Mountains, Texas) may be intermediate. However, in Chisos Mountains the two species seem to be sharply defined morphologically and widely separated ecologically.</p>
