--><span class="statement" id="st-undefined" data-properties="">Perennials; long-lived; sexual; caudex woody (often with persistent, crowded leaf bases). <b>Stems</b> usually 1 per caudex branch, arising from center of rosette near ground surface, 1–4(–5) dm, densely pubescent proximally, trichomes short-stalked, 2–6-rayed, 0.1–0.2 mm, sparsely pubescent distally. <b>Basal</b> leaves: blade narrowly oblanceolate, 1–4(–5) mm wide, margins prominently dentate to subpinnatifid (leaf margins of sterile shoots often entire), ciliate near petiole base, trichomes (simple or 2-rayed), 0.4–0.6 mm, surfaces densely pubescent, trichomes short-stalked, (2–)4–9-rayed, 0.05–0.2 mm. <b>Cauline</b> leaves: (10–)20–60, often concealing stem throughout; blade auricles 0.5–3 mm, surfaces of distalmost leaves moderately to sparsely pubescent. <b>Racemes</b> 8–30-flowered, usually unbranched. <b>Fruiting</b> pedicels reflexed, strongly recurved, 5–15 mm, pubescent, trichomes appressed, branched. <b>Flowers</b> divaricate-ascending to pendent at anthesis; sepals pubescent; petals usually purple, rarely lavender, 9–14 × 1.5–3 mm, glabrous; pollen ellipsoid. <b>Fruits</b> pendent, not appressed to rachis, not secund, straight to slightly curved, edges parallel, (3.5–)5–8 cm × (1.6–)2–3 mm; valves pubescent throughout; ovules 24–42 per ovary; style 0.5–1 mm. <b>Seeds</b> uniseriate, 2.5–3.5 × 1.5–2.2 mm; wing continuous or at both ends, 0.4–0.8 mm wide. <b>2n</b> = 14.</span><!--

|discussion=<p>Originally thought to be restricted to northern California and adjacent Oregon, <i>Boechera subpinnatifida</i> is a sexual species that recently has been found in central Idaho, northern <i>Nevada</i>, and northwestern Utah. It appears to intergrade with both <i>B. puberula</i> and <i>B. retrofracta</i>, and species boundaries within this complex need further study.</p>
