--><span class="statement" id="st-undefined" data-properties=""><b>Biennials </b>or perennials; (short-lived, often woody basally); glabrous or hirsute. <b>Stems</b> (several from base), branched basally, 5–10 dm, (usually glabrous, rarely sparsely hirsute). <b>Basal</b> leaves: blade (usually bright green), obovate to elliptic (not lobed), (3–)5–20(–30) cm × (5–)10–35(–60) mm, (base cuneate), margins subentire to dentate, (surfaces glabrous or often with trichomes minute, tubercled-based, curved, coarse). <b>Cauline</b> leaves (distal) shortly petiolate; blade (oblong or lanceolate, to 10 cm) base not auriculate or amplexicaul. <b>Racemes</b> paniculately branched. <b>Fruiting</b> pedicels spreading to divaricately ascending, (6–)8–18 mm. <b>Flowers</b>: sepals 3–4(–4.5) × 1–1.5 mm; petals bright yellow to orange-yellow, obovate, (5–)7–10 × 2.5–3.5(–4) mm, claw 2.5–4 mm, apex rounded; filaments 3.5–4.5 mm; anthers 1–1.5 mm; gynophore 1.5–4(–5) mm in fruit. <b>Fruits</b> (stipitate), spreading to ascending (not appressed to rachis), torulose, terete, (1.5–)2–4(–4.8) cm × (1–)1.5–2 mm; valvular segment with (2–)5–11(–13) seeds per locule, (1.2–)1.6–4(–4.5) cm, terminal segment seedless, 0.5–2.5(–3) mm. <b>Seeds</b> grey to brown, 1–1.6 mm diam.; seed coat reticulate, mucilaginous when wetted. <b>2n</b> = 22.</span><!--

|discussion=<p>The earliest North American collections of Brassica elongata were from ballast at Linnton, near Portland, Oregon, in 1911, and from a garden in Bingen, Klickitat County, Washington, in 1915. The species does not appear to have persisted at, or spread from, either location (R. C. Rollins and I. A. Al-Shehbaz 1986). It was next collected in 1968 from east-central Nevada, where it is now well-established in Eureka and White Pine counties, and just into Lander County, and spreading rapidly along both roadsides and adjacent high desert (Rollins 1980; Rollins and Al-Shehbaz; Rollins 1993). The semiarid region of North America appears to be a well-suited habitat for B. elongata and the species appears destined to become a permanent part of the flora of the Intermountain Basin (Rollins and Al-Shehbaz).</p><!--
--><p>According to R. C. Rollins (1980), the Nevada plants belong to subsp. integrifolia (Boissier) Breistroffer, but the species is so variable that dividing it into infraspecific taxa is not practical.</p>
