|discussion=<p><i>Boerhavia coulteri </i>var.<i> palmeri</i> is a desert taxon primarily from south of the Mogollon Rim; its occurrence in southern New Mexico and western Texas, and on the Channel Islands, is perhaps the result of introductions. It seems very closely related to <i>B. torreyana</i>, distinguished by the less rugose ribs and narrower, nonpapillate sulci. The two may intergrade in southeastern Arizona. For decades <i></i></i>var.<i><i> palmeri</i> has been included without taxonomic recognition within a broadly constructed <i>B. coulteri</i>. The latter is usually a more robust taxon with densely fruited inflorescences and more or less truncate fruits. The two are often sympatric, either in mixed populations, or with <i>B. coulteri </i>var.<i> palmeri</i> inhabiting nearby slightly drier sites. Though most specimens are easily placed into one variety or the other, the two intergrade and hybridization is likely.</p>
