--><span class="statement" id="st-undefined" data-properties="">Perennials; usually short-lived; sexual; caudex not woody. <b>Stems</b> usually 1 per caudex branch, arising from center of rosette near ground surface, (1.5–)2.5–8 dm, densely pubescent proximally, trichomes simple and short-stalked, 2-rayed, to 1 mm, sparsely pubescent or glabrous distally. <b>Basal</b> leaves: blade oblanceolate, 1–7 mm wide, margins entire or dentate, ciliate along petiole, trichomes (simple), to 0.7 mm, surfaces moderately to densely pubescent, trichomes short-stalked, 5–8-rayed, 0.15–0.4 mm. <b>Cauline</b> leaves: (8–)15–40, concealing stem proximally; blade auricles 1–3 mm, surfaces of distalmost leaves usually sparsely pubescent. <b>Racemes</b> (15–)30–90-flowered, usually unbranched. <b>Fruiting</b> pedicels reflexed, abruptly recurved at base, otherwise straight, 4–13 mm, glabrous or sparsely pubescent, trichomes usually simple. <b>Flowers</b> descending to pendent at anthesis; sepals pubescent; petals usually white, rarely lavender, 4–6 × 0.8–1.5 mm, glabrous; pollen ellipsoid. <b>Fruits</b> strongly reflexed, usually appressed to rachis, rarely somewhat secund, straight, edges parallel, 3.5–6 cm × 0.9–1.5 mm; valves glabrous; ovules 70–126 per ovary; style 0.2–0.5 mm. <b>Seeds</b> uniseriate, 1–1.4 × 0.8–1 mm; wing continuous (rarely absent), to 0.1 mm wide. <b>2n</b> = 14.</span><!--

|discussion=<p>Though often treated as a variety of <i>Arabis</i> (<i>Boechera</i>) holboellii (e.g., R. C. Rollins 1993; G. A. Mulligan 1996), <i>B. collinsii</i> is easily distinguished from that species by having simple and 2-rayed (versus 4–8-rayed) trichomes proximally on stems, and narrower (0.9–1.5 versus 2–2.5 mm) usually non-secund fruits. The two taxa also show allopatric distributions, with <i>B. collinsii</i> found on the North American continent (usually east of the Rocky Mountains) and <i>B. holboellii</i> apparently confined to Greenland.</p>
