Discussion
Boerhavia coulteri var. palmeri 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 B. torreyana, distinguished by the less rugose ribs and narrower, nonpapillate sulci. The two may intergrade in southeastern Arizona. For decades var. palmeri has been included without taxonomic recognition within a broadly constructed B. coulteri. 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 B. coulteri var. palmeri inhabiting nearby slightly drier sites. Though most specimens are easily placed into one variety or the other, the two intergrade and hybridization is likely.
