|discussion=<p>North American populations of <i>Saussurea nuda</i> occur in two distinctly different sets of habitats. Plants from coastal Alaska have been recognized as var. nuda and dwarfed alpine plants from the northern Rockies as <i></i>var.<i> densa</i>. According to E. Hultén (1941–1950, vol. 10), the only differences between <i></i>var.<i> densa</i> and var. nuda are the “more densely denticulated leaves and very congested inflorescences” of the former. Notwithstanding the very different habitats, some coastal Alaskan specimens [e.g., Ward 53 (ALA)] are indistinguishable from the alpine forms. In Siberia, <i>S. nuda</i> is a polymorphic species occurring from coastal sites to alpine areas (S. J. Lipschitz 1979).</p><!--
--><p><i>Saussurea</i> ×tschuktschorum Lipschitz is apparently a hybrid between <i>S. angustifolia</i> and <i>S. nuda</i>. It resembles <i>S. angustifolia</i>; it has naked receptacles like <i>S. nuda</i>.</p>
