|discussion=<p>The name <i>Amaranthus torreyi</i> has been widely misapplied to at least two other species, 7. <i>A. arenicola</i> and 6. <i>A. watsonii</i>. Because of that, the name <i>A. bigelovii</i> was used for <i>A. torreyi</i> by J. D. Sauer (1955) and in some recent floras. Sometimes <i>A. torreyi</i> (California and Arizona) and <i>A. bigelovii</i> (New Mexico and Texas) are recognized as separate species. The nomenclature and taxonomic relationships in this group should be critically reviewed based on type specimens and additional experimental and field studies.</p>
