--><span class="statement" id="st-undefined" data-properties="">Perennials; short- to long-lived; sexual; caudex usually not woody. <b>Stems</b> usually 1 per caudex branch, arising from center of rosette near ground surface, 0.6–3 dm, densely pubescent proximally, trichomes simple and stalked, 2–4-rayed, 0.1–0.4 mm, glabrous or sparsely pubescent distally. <b>Basal</b> leaves: blade narrowly oblanceolate, 1.5–4(–5) mm wide, margins entire, often ciliate along petiole, trichomes (simple), to 0.6 mm, surfaces densely pubescent, trichomes short-stalked, 4–8-rayed, 0.08–0.2 mm. <b>Cauline</b> leaves: 6–17, sometimes concealing stem proximally; blade auricles absent, surfaces of distalmost leaves glabrous or sparsely pubescent. <b>Racemes</b> 4–11-flowered, unbranched. <b>Fruiting</b> pedicels arched, gently recurved, 3–8(–12) mm, glabrous or sparsely pubescent, trichomes appressed, branched. <b>Flowers</b> ascending at anthesis; sepals pubescent; petals white or lavender, 4–6 × 1–1.5 mm, glabrous; pollen ellipsoid. <b>Fruits</b> pendent, not appressed to rachis, not secund, usually straight, edges parallel, (2–)2.5–3.8 cm × 1.5–2.2 mm; valves glabrous; ovules 66–92 per ovary; style 0.3–0.5 mm. <b>Seeds</b> sub-biseriate, 1–1.2 × 0.7–0.9 mm; wing distal, 0.05–0.1 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), <i>B. pendulocarpa</i> is easily distinguished from that species by having simple and 2–4-rayed (versus 4–8-rayed) trichomes proximally on stems, cauline leaves without auricles, fruiting pedicels gently (versus sharply) recurved, and shorter (2–)2.5–3.8 (versus 3.5–6.5) cm, non-secund fruits. The two taxa have allopatric distributions, with <i>B. pendulocarpa</i> found in the mountains of western North America and <i>B. holboellii</i> apparently confined to Greenland. Recent use of the name A. (<i>Boechera</i>) exilis for this taxon (e.g., G. A. Mulligan 1996; R. D. Dorn 2001; N. H. Holmgren 2005b) is based on misinterpretation of the type (M. D. Windham and I. A. Al-Shehbaz 2006).</p>
