--><p>As delimited by R. C. Rollins (1943, 1976, 1993), <i>Halimolobos</i> consists of 18 species distributed in North America and South America. Detailed molecular studies (C. D. Bailey et al. 2002) and critical evaluation of morphology (Bailey et al. 2007) indicate that Rollins’s concept of the genus corresponds to at least four well-defined genera, <i>Halimolobos</i> in the narrow sense, <i>Sandbergia</i>, <i>Transberingia</i>, and Exhalimolobos, of which only the last is not represented in the flora area. Both Exhalimolobos and <i>Halimolobos</i> are members of the tribe Halimolobeae, <i>Sandbergia</i> belongs to the tribe Boechereae; <i>Transberingia</i> is sister to the Asian Crucihimalaya Al-Shehbaz, O’Kane & R. A. Price of the tribe Camelineae; see Bailey et al. (2002, 2007).</p>
