--><span class="statement" id="st-undefined" data-properties="">Perennials; long-lived; sexual; caudex woody. <b>Stems</b> usually 1 per caudex branch, arising from center of leaf tuft, above ground surface on woody base, 2–5.5 dm, densely pubescent proximally, trichomes short-stalked, 4–7-rayed, 0.1–0.4 mm, similarly pubescent distally. <b>Basal</b> leaves: blade linear to linear-oblanceolate, 2–3(–4) mm wide, margins entire, sometimes ciliate near petiole base, trichomes (simple or 2-rayed), to 0.8 mm, surfaces densely pubescent, trichomes short-stalked, 4–8-rayed, 0.1–0.3 mm. <b>Cauline</b> leaves: 7–18, concealing stem proximally; blade auricles absent, surfaces of distalmost leaves densely pubescent. <b>Racemes</b> 6–26-flowered, usually unbranched. <b>Fruiting</b> pedicels horizontal to descending, usually recurved, 5–10(–20) mm, pubescent, trichomes appressed, branched. <b>Flowers</b> divaricate at anthesis; sepals pubescent; petals white to pale lavender, 8–18 × 2.5–4.4(–5.5) mm, glabrous; pollen ellipsoid. <b>Fruits</b> divaricate-descending to reflexed, usually not appressed to rachis, rarely somewhat secund, straight, edges parallel, 4.3–7 cm × 1.6–3 mm; valves pubescent throughout; ovules 72–98 per ovary; style ca. 0.1 mm. <b>Seeds</b> biseriate, 1.2–1.6 × 1–1.2 mm; wing continuous, 0.1–0.2 mm wide. <b>2n</b> = 14.</span><!--

|discussion=<p>Although <i>Boechera formosa</i> is usually subsumed within <i>Arabis</i> (<i>Boechera</i>) pulchra, the two species are easily separated. <i>Boechera formosa</i> has white to lavender (versus mostly purple) petals, fruiting pedicels that are not abruptly recurved at the base, narrower (1.6–3 versus 2.5–4 mm wide), mostly non-appressed fruits, and narrower (1–1.2 versus 1.5–2.2 mm wide) seeds. The two taxa are separated by more than 500 km, with <i>B. formosa</i> found only on the Colorado Plateau and <i>B. pulchra</i>, in the strict sense, restricted to southern California, western <i>Nevada</i>, and northwestern Mexico.</p>
