--><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 Boechera formosa is usually subsumed within Arabis (Boechera) pulchra, the two species are easily separated. Boechera formosa 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 B. formosa found only on the Colorado Plateau and B. pulchra, in the strict sense, restricted to southern California, western Nevada, and northwestern Mexico.</p>
