--><p>Variety depressa grows in geyser basins in Yellowstone National Park and is locally common in rocky soils in Teton National Park; it is very rare farther south in Wyoming. It is distinguished by its small stature, small heads, and linear-oblanceolate leaves with many hairs and usually some glands. It is similar to some forms of <i></i>var.<i> minor</i>, which occur throughout the range of <i></i>var.<i> depressa</i> and with which it hybridizes. It is also similar to hairier forms of <i></i>var.<i> villosa</i>. Typical <i></i>var.<i> depressa</i> occupies the vicinity of hot springs and geyser basins and nearby river flood banks, while <i></i>var.<i> minor</i> occupies other drier or non-geyserite nearby habitats.</p>
