--><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 Arabis (Boechera) holboellii (e.g., R. C. Rollins 1993), B. pendulocarpa 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 B. pendulocarpa found in the mountains of western North America and B. holboellii apparently confined to Greenland. Recent use of the name A. (Boechera) 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>
