--><span class="statement" id="st-undefined" data-properties="">Perennials; short-lived; sexual; caudex usually not woody. <b>Stems</b> usually 2–5 per caudex branch, arising from margin of rosette near ground surface, or arising laterally proximal to sterile shoots, (0.5–)1.5–4 dm, densely pubescent proximally, trichomes short-stalked, 2–6-rayed, 0.1–0.3 mm, glabrous or sparsely pubescent distally. <b>Basal</b> leaves: blade oblanceolate to obovate, 5–11(–13) mm wide, margins shallowly dentate or, sometimes, entire, often ciliate along petiole, trichomes (simple and 2-rayed), surfaces moderately pubescent, trichomes short-stalked, 4–8-rayed, 0.1–0.3 mm. <b>Cauline</b> leaves: 3–8(–11), not concealing stem; blade auricles (0.5–)1–2 mm, surfaces of distalmost leaves sparsely pubescent. <b>Racemes</b> 4–15(–20)-flowered, usually unbranched. <b>Fruiting</b> pedicels ascending to divaricate-ascending, straight or, sometimes, recurved, 7–15 mm, glabrous or sparsely pubescent. <b>Flowers</b> ascending at anthesis; sepals pubescent; petals usually lavender, rarely whitish, 5–9 × 1.2–2.5 mm, glabrous; pollen ellipsoid. <b>Fruits</b> usually ascending, rarely horizontal, not appressed to rachis, not secund, straight to curved, edges parallel, 2.5–5(–6.5) cm × 1–2 mm; valves glabrous; ovules 44–62 per ovary; style 0.05–0.4 mm. <b>Seeds</b> uniseriate, 1.1–1.3 × 1–1.1 mm; wing nearly continuous, 0.07–0.15 mm wide.</span><!--

|discussion=<p>Although Boechera pallidifolia was originally described as endemic to west-central Colorado, recent studies favor a broader circumscription that includes sexual populations previously assigned to Arabis (Boechera) selbyi (see M. D. Windham and I. A. Al-Shehbaz 2006 for detailed comparison). The species has hybridized with nearly every sexual diploid within its range (including B. crandallii, B. fendleri, B. formosa, and B. pendulina), producing a confusing array of apomictic triploids including the type specimen of A. selbyi.</p>
