--><span class="statement" id="st-undefined" data-properties="">Perennials; (cespitose); caudex simple or branched (with some persistent leaf bases); scapose. <b>Stems</b> unbranched, 0.3–1(–1.3) dm, often glabrous throughout, sometimes sparsely pubescent proximally, trichomes simple and stalked, 2-rayed, 0.2–1 mm. <b>Basal</b> leaves rosulate; sessile; blade (fleshy), oblanceolate to linear, (0.4–)0.5–1.4(–2) cm × (1–)1.5–3(–4) mm, margins entire, (ciliate at least apically, trichomes simple and 2-rayed), surfaces usually glabrous, rarely sparsely pubescent with simple and stalked, 2- (or 3-)rayed trichomes, 0.2–1 mm, (midvein obscure). <b>Cauline</b> leaves 0. <b>Racemes</b> (6–)10–28(–40)-flowered, ebracteate, elongated in fruit; rachis not flexuous, glabrous. <b>Fruiting</b> pedicels divaricate-ascending, straight, (3–)5–10(–17) mm, glabrous. <b>Flowers</b>: sepals broadly ovate, 1.7–2.5 mm, usually glabrous, rarely pubescent, (trichomes simple and short-stalked, 2-rayed); petals white, spatulate to obovate, 3–5 × 2–3 mm; anthers oblong, 0.5–0.7 mm. <b>Fruits</b> ovoid to lanceolate, plane, inflated at least basally, 4–8(–10) × 2.5–4 mm; valves glabrous or sparsely puberulent, trichomes simple, 0.02–0.1 mm; ovules 6–12 per ovary; style 0.2–0.9 mm. <b>Seeds</b> ovoid, 1–1.5 × 0.7–1.1 mm. <b>2n</b> = 26.</span><!--

|discussion=<p>Molecular studies (M. A. Beilstein and M. D. Windham 2003) and chromosomal data (Windham 2000, 2004) suggest that <i>Draba subalpina</i> is most closely related to <i>D. cusickii</i> and <i>D. sobolifera</i>. From those, it is easily distinguished by having white (versus yellow) petals, glabrous (versus pubescent) rachises and stems distally, and glabrous or, rarely, sparsely pubescent (versus always pubescent) abaxial leaf blade surfaces. <i>Draba subalpina</i> is known from Garfield, Iron, Kane, and Wayne counties in south-central Utah.</p>
