|discussion=<p>New Mexico records of <i>Echinocereus fasciculatus</i> are at least in part based on vigorous old plants of <i>E. fendleri</i>, which sometimes have 1–2 short supplementary central spines (and which appear very different from younger plants in the same populations). <i>Echinocereus fasciculatus</i> may prove to intergrade clinally with <i>E. engelmannii</i> var. acicularis wherever their geographic ranges approach each other. At its upper altitudinal limit, <i>E. fasciculatus</i> tends to have shorter spines, fewer central spines, shorter stems, and more compact growth habit.</p>
