--><p>E. Ulbrich (1934) circumscribed section Deserticola to include all of the shrubby species of <i>Atriplex</i> except for <i>Atriplex canescens</i>, which he included within Obione subgenus Pterochiton. The name Deserticola was taken by J. McNeill et al. (1983) to include not only <i>A. canescens</i> per se, but representatives of other groups containing woody taxa, as treated by P. C. Standley. <i>Atriplex canescens</i> is known to form hybrids with numerous other taxa of woody <i>Atriplex</i>. Thus, most of the woody species are in some large part closely allied and capable of hybridization to a greater or lesser extent. Members of the subgenus, despite their near relationships, also show affinities that lead back through time to some ancestor or ancestors common to both them and with those of subgenus Obione. They do not, however, appear to have arisen as end points of evolution from various places within that subgenus, i.e., the subgenus Pterochiton appears to be monophyletic.</p>
