--><span class="statement" id="st-undefined" data-properties=""><b>Biennials </b>or perennials; short-lived; apomictic or sexual; caudex present or absent. <b>Stems</b> usually 1 per caudex branch, arising from center of rosette near ground surface, 2–6.7 dm, densely pubescent proximally, trichomes short-stalked, 4–8-rayed, 0.1–0.3 mm, glabrous or sparsely pubescent distally. <b>Basal</b> leaves: blade oblanceolate, 2–5 mm wide, margins entire, sometimes ciliate near petiole base, trichomes (usually simple), to 0.7 mm, surfaces sparsely to moderately pubescent, trichomes short-stalked, 4–8-rayed, 0.1–0.3 mm. <b>Cauline</b> leaves: 7–40, often concealing stem proximally; blade auricles 1–4 mm, surfaces of distalmost leaves glabrous or sparsely pubescent. <b>Racemes</b> 10–60-flowered, usually unbranched. <b>Fruiting</b> pedicels descending to reflexed, most abruptly recurved near base, 5–10 mm, glabrous or sparsely pubescent, trichomes appressed, branched. <b>Flowers</b> divaricate to pendent at anthesis; sepals pubescent; petals white, 4–8 × 1–2 mm, glabrous; pollen ellipsoid or spheroid. <b>Fruits</b> descending to reflexed, not appressed to rachis, strongly secund, often curved, edges parallel, 0.35–0.65 cm × (2–)2.2–2.5 mm; valves glabrous; ovules 80–102 per ovary. <b>Seeds</b> uniseriate to sub-biseriate, 1.4–1.7 × 1–1.2 mm; wing continuous, to 0.2 mm wide. <b>2n</b> = 14, 21.</span><!--

|discussion=<p>Both sexual diploid and apomictic triploid collections of <i>Boechera holboellii</i> are known; available data suggest that the triploid is an autopolyploid derivative of the sexual diploid but further study is needed. In the narrow circumscription adopted here, it appears to be restricted to Greenland (see discussion of <i>B. quebecensis</i> in M. D. Windham and I. A. Al-Shehbaz 2007b).</p>
