|discussion=<p>Variety pansum occurs in two disjunct series of scattered populations. One is in central Idaho (Blaine, Boise, Custer, Elmore, Lemhi, and Valley counties); the second is in western Montana (Lewis and Clark, Lincoln, Missoula, Powell, Sanders, and Silver Bow counties). This variety bridges the morphologic gap between <i>E. ovalifolium</i> and <i>E. strictum </i>var.<i> proliferum</i>. The inflorescence of <i></i>var.<i> pansum</i> is umbellate with branches up to 3 cm long, but never compoundly branched as in <i>E. strictum</i>. The umbellate condition becomes obvious only in late anthesis or during early fruit-set, so immature plants of <i></i>var.<i> pansum</i> might be mistaken for <i></i>var.<i> purpureum</i>, large specimens of <i></i>var.<i> depressum</i>, or short-scaped plants of <i></i>var.<i> ochroleucum</i>. Still, careful observation of such specimens will show an early branching condition, although this can be obscured by bracts subtending the inflorescence or an abundance of early flowers in the numerous involucres. The branched cushion wild buckwheat is certainly worth consideration as an ornamental.</p>
