--><span class="statement" id="st-undefined" data-properties="">Perennials; (cespitose); caudex branched (with persistent leaf remains, branches sometimes terminating in sterile rosettes); scapose. <b>Stems</b> unbranched, 0.2–1.1(–1.5) dm, pubescent proximally, trichomes 2–9-rayed, 0.05–0.2 mm, glabrous or sparsely pubescent distally. <b>Basal</b> leaves rosulate; petiolate; petiole (thickened), ciliate proximally, (margin not ciliate, trichomes simple and 2-rayed, 0.2–0.5 mm); blade oblanceolate to obovate, 0.3–0.9(–1.5) cm × 1–4 mm, margins usually entire, rarely denticulate, surfaces pubescent with minutely stalked, 8–16-rayed, stellate trichomes, 0.08–0.3 mm, (midvein obscure abaxially). <b>Cauline</b> leaves 0. <b>Racemes</b> 5–17-flowered, ebracteate, elongated in fruit; rachis not flexuous, usually glabrous, rarely sparsely pubescent as stem. <b>Fruiting</b> pedicels divaricate-ascending, straight, (slender), 4–10 mm, usually glabrous, rarely sparsely pubescent as stem. <b>Flowers</b>: sepals ovate, 2–2.5 mm, pubescent, (trichomes simple and short-stalked, 2–6-rayed); petals white or creamy white, obovate, 4.5–5.5 × 2–3 mm; anthers ovate, 0.4–0.6 mm. <b>Fruits</b> (often aborting, becoming lopsided), oblong to elliptic or ovate, plane, flattened, 4–8 × 2–3 mm; valves glabrous; ovules 18–32 per ovary; style 0.3 0.8 mm. <b>Seeds</b> ovoid, 0.9–1.1 × 0.5–0.7 mm. <b>2n</b> = 16, 32, 64.</span><!--

|discussion=<p>North American plants of <i>Draba palanderiana</i> are diploid and appear to be self-incompatible, an unusual situation among arctic members of the genus. By contrast, some plants from the Russian Far East are tetraploid (2n = 32) or octoploid (2n = 64) and appear to be self-compatible. Detailed studies are needed to establish whether one or two taxa are involved.</p><!--
--><p>Many North American collections of <i>Draba palanderiana</i> have been misidentified as <i>D. nivalis</i>. The species is easily separated from <i>D. nivalis</i> by having ciliate (versus non-ciliate) bases of basal leaves, larger petals (4.5–5.5 × 2–3 versus 2–3.5 × 0.8–1.4 mm) that are pale yellow or cream (versus white), and longer fruiting pedicels 4–10 [versus 1–4.5(–8)] mm.</p>
