|discussion=<p>Our northern plants of Echinocereus pentalophus are var. procumbens (Engelmann) P. Fournier; they have often been misidentified as E. berlandieri. Both taxa have often been misidentified as the Mexican species E. blanckii [often misspelled as E. “blankii”], of confused authorship. Confusing variation of E. pentalophus has promulgated misidentifications, misapplications of names, and attempts to recognize multiple taxa.</p>
