--><span class="statement" id="st-undefined" data-properties="">Perennials; short- to long-lived; sexual; caudex usually not woody (rarely with persistent, crowded leaf bases). <b>Stems</b> simple or few to several per caudex branch, arising from center of rosette near ground surface, 1.5–3.5(–5) dm, densely pubescent proximally, trichomes simple mixed with short-stalked ones, 2-rayed, 0.3–0.7 mm. <b>Basal</b> leaves: blade narrowly oblanceolate, 1.5–3(–4) mm wide, margins entire, strongly ciliate at least along petiole, trichomes (simple), to 1 mm, surfaces glabrous or sparsely pubescent, trichomes simple and short-stalked, 2-rayed, 0.3–0.7 mm. <b>Cauline</b> leaves: 5–15(–20), often concealing stem proximally; blade auricles 0.5–1.5 mm, surfaces of distalmost leaves usually glabrous. <b>Racemes</b> 10–30-flowered, usually unbranched. <b>Fruiting</b> pedicels horizontal or slightly descending, curved or angled downward, 6–10(–15) mm, usually glabrous, rarely sparsely pubescent, trichomes spreading, simple. <b>Flowers</b> divaricate-ascending at anthesis; sepals pubescent; petals usually white, rarely pale lavender, 3–3.7(–4) × 0.5–0.8 mm, glabrous; pollen ellipsoid. <b>Fruits</b> pendent, not appressed to rachis, rarely slightly secund, straight or gently curved, edges parallel, 3.3–5.7 cm × 1.2–1.8 mm; valves glabrous; ovules 90–126 per ovary; style 0.1–0.4 mm. <b>Seeds</b> biseriate, 0.7–0.9 × 0.5–0.6 mm; wing distal or, sometimes, absent, 0.05–0.1 mm wide. <b>2n</b> = 14.</span><!--

|discussion=<p><i>Boechera spatifolia</i> is a sexual diploid that usually has been treated as a variety of <i>Arabis</i> (<i>Boechera</i>) fendleri but appears to be sufficiently distinct to warrant recognition at species level (see M. D. Windham and I. A. Al-Shehbaz 2006 for detailed comparison). There is little geographic overlap between the two, with <i>B. spatifolia</i> confined to the mountains of central Colorado and north-central New Mexico and <i>B. fendleri</i> ranging from western New Mexico and the Four Corners region through northern Arizona to southern <i>Nevada</i>.</p>
