--><span class="statement" id="st-undefined" data-properties=""><b>Stems:</b> young long shoots glabrous or sparsely hirtellous, often stipitate-glandular. <b>Leaves</b> monomorphic, both long- and short-shoot leaves winter persistent; blade obovate to spatulate (when small), coriaceous-thickened, 3(–5)-lobed, lobes oblong-linear, narrow, central lobe deflexed, 2 lateral ascending, margins strongly revolute, often with large, resiniferous, punctate glands, abaxial surface arachnoid-villous, midvein glabrous, glabrate, or hirtellous, adaxial glabrous, sometimes weakly arachnoid-villous (this often obscured by broad, glabrous midvein in dried leaves) or hirtellous. <b>2n</b> = 18.</span><!--

|discussion=<p>Variety glandulosa is a derivative of <i></i>var.<i> tridentata</i>. Some sterile specimens of <i></i>var.<i> glandulosa</i> cannot be distinguished from <i>Purshia stansburyana</i>; both taxa sometimes have similar leaves, and hirtellous, more or less stipitate-glandular young stems.</p><!--
--><p>G. L. Stebbins (1959) and H. C. Stutz and L. K. Thomas (1963) hypothesized that <i></i>var.<i> glandulosa</i> is a product of hybridization and introgression between <i>Purshia tridentata</i> and <i>P. stansburyana</i>. Although introgression would explain certain similarities, <i>P. tridentata</i> stands as a distinct species strongly differentiated by ovary-fruit characteristics and dimorphic leaves, which allow it to adapt to a wide range of habitats. Hybrids with <i>P. stansburyana</i> are discussed under the latter species.</p>
