--><span class="statement" id="st-undefined" data-properties="">Perennials; long-lived; (cespitose); sexual; caudex woody (thickly covered by persistent, crowded leaf bases). <b>Stems</b> usually 1 per caudex branch, arising from center of rosette near ground surface, 0.6–2.3 dm, glabrous throughout. <b>Basal</b> leaves: blade oblanceolate, 3.5–14 mm wide, margins usually entire, rarely slightly dentate, not ciliate, surfaces glabrous. <b>Cauline</b> leaves: 3–10, not concealing stem; blade auricles absent, glabrous. <b>Racemes</b> 4–24-flowered, usually unbranched. <b>Fruiting</b> pedicels ascending, straight, 3–18 mm, glabrous. <b>Flowers</b> ascending at anthesis; sepals glabrous; petals white to lavender, 6–10 × 2.5–4 mm, glabrous; pollen ellipsoid. <b>Fruits</b> ascending to divaricate-ascending, not appressed to rachis, not secund, straight to slightly curved, edges parallel, 2.5–7 cm × 1.5–2.5 mm; valves glabrous; ovules 28–50 per ovary; style 0.1–0.8 mm. <b>Seeds</b> uniseriate, 1.8–2.2 × 0.8–1.7 mm; wing distal or continuous, 0.1–0.5 mm wide.</span><!--

|discussion=<p>Plants of <i>Boechera davidsonii</i> sometimes are confused with completely glabrous individuals of <i>B. lyallii</i>, and G. A. Mulligan (1996) treated it as a synonym of the latter. It is easily distinguished from <i>B. lyallii</i> by the thick covering of persistent leaf bases on caudex branches, ascending (versus erect and appressed) fruits, and uniseriate (versus biseriate to sub-biseriate) seeds. <i>Boechera davidsonii</i> is nearly unique among western North American species of the genus in showing no evidence of hybridization with other species.</p>
