--><p>For a detailed account on the generic limits and affinities of <i>Hesperidanthus</i>, see I. A. Al-Shehbaz (2005). As delimited here, the genus includes what R. C. Rollins (1993) assigned to Schoenocrambe Greene (minus the type), Caulostramina, and Glaucocarpum. One species is endemic to Inyo County, California, three are highly localized endemics in Utah, and the fifth is widespread in the southwestern United States and northern Mexico.</p>
