|discussion=<p>Of conservation concern.</p><!--
--><p>The entire <i>Echinocereus reichenbachii</i> species group (<i>E. reichenbachii</i>, <i>E. chisosensis</i>, <i>E. rigidissimus</i>, <i>E. pseudopectinatus</i>, and an indefinite number of Mexican species) has unusually thin, bristlelike spines clothing the flowers and fruits as well as conspicuous, cobwebby tomentum of unusually long areolar hairs. The persistent, dry, white features of the flower tube are an essential distinction contrasting with the otherwise similar <i>E. pectinatus</i> species group (<i>E. pectinatus</i>, <i>E. dasyacanthus</i>, and possibly <i>E. bonkerae</i>), regardless of the spectacular, colorful floral displays.</p><!--
--><p>The taxonomic and geographic boundaries among the segregate species or numerous proposed infraspecific taxa of <i>Echinocereus reichenbachii</i> remain nebulous and controversial. In no place do pure populations exist sympatrically, and all taxa appear completely interfertile. Typical <i>E. reichenbachii</i> is endemic to Mexico, near Saltillo, Coahuila. The common plants of <i>E. reichenbachii</i> in Texas, usually lacking central spines, are weakly distinguished from typical <i>E. reichenbachii</i> and are the basis for <i>E. reichenbachii</i> subsp. caespitosus. Oklahoma populations with unusually long bristlelike spines were named <i>E. baileyi</i> Rose [<i>E. reichenbachii</i> subsp. baileyi]. They intergrade, however, with the nearby, short-spined populations of <i>E. reichenbachii</i>. <i>Echinocereus reichenbachii</i> var. albispinus pertains to intermediates between <i>E. baileyi</i> and <i>E. reichenbachii</i> subsp. caespitosus. The flowers of <i>E. reichenbachii</i> var. fitchii are among the largest in the species, and their exact color pattern may prove taxonomically significant. <i>Echinocereus reichenbachii</i> var. albertii is somewhat morphologically and geographically intermediate between <i></i>var.<i> caespitosus</i> and var. fitchii, but with flowers more closely resembling var. fitchii; it is sometimes considered a synonym of var. fitchii or a variety of E. fitchii Britton & Rose. The name “<i>Echinocereus</i> melanocentrus” appears frequently in cactus literature but has not been validly published.</p><!--
