|discussion=<p>Contrary to L. D. Benson’s (1982) map of <i>Ferocactus hamatacanthus</i>, all populations in southern Texas are <i></i></i>var.<i><i> sinuatus</i>. The southern Texas populations form a geographically cohesive taxon superficially similar to <i>Hamatocactus bicolor</i> in their narrow ribs and overall green aspect unlike the coarse, strongly xerophytic <i>F. hamatacanthus </i>var.<i> hamatacanthus</i> farther west. Only the populations in the lower Pecos River region might be intermediates between vars. sinuatus and hamatacanthus.</p>
