--><span class="statement" id="st-undefined" data-properties="">Perennials; (caudex often thick, not aboveground, covered with persistent petiolar remains); puberulent. <b>Stems</b> several from base (caudex), ascending, branched distally, (1–)1.5–3.5(–4) dm. <b>Basal</b> leaves rosulate; petiole (0.5–)1.5–6(–7.5) cm; blade oblanceolate to obovate, (1.5–)2.5–7(–9) cm × (10–)15–25 mm, margins usually entire, rarely denticulate subapically. <b>Cauline</b> leaves shortly petiolate or sessile; blade narrowly lanceolate to broadly oblanceolate, 1–5 cm × 2–9(–12) mm, base cuneate, not auriculate, margins usually entire, rarely denticulate subapically. <b>Racemes</b> elongated in fruit; rachis puberulent, trichomes straight, sometimes clavate. <b>Fruiting</b> pedicels divaricate-ascending to horizontal, straight, (not winged), (4–)5–10 × 0.3–0.5 mm, puberulent adaxially. <b>Flowers</b>: sepals oblong-obovate, (1.5–)1.8–2.5 × 0.8–1.3 mm; petals white, obovate, (2.3)2.5–3.6(–4) × 1.5–2.2 mm, claw 0.5–1 mm; stamens (2 or) 4 (or 6), median and lateral when 4, (erect); filaments 1.7–2.5 mm, (glabrous); anthers 0.5–0.8 mm. <b>Fruits</b> ovate, (3–)3.2–4(–4.4) × 2–3.5 mm, apically winged, apical notch 0.1–0.3 mm deep; valves thin, smooth, not veined, glabrous; style 0.5–0.8(–1) mm, exserted beyond apical notch. <b>Seeds</b> ovate, 1.8–2 × 0.9–1.1 mm.</span><!--

--><p>The circumscription of <i>Lepidium integrifolium</i> is somewhat controversial. C. L. Hitchcock (1936) treated it as two varieties or (Hitchcock 1950) two subspecies of <i>L. montanum</i>, whereas R. C. Rollins (1993) treated it as a distinct species with two varieties. Rollins indicated that the species has two stamens, but such occurrence is rather rare. Most commonly, it has four stamens and is readily distinguished from related species by having four nectar glands and sepals sparsely pubescent subapically with crisped trichomes. Nothing is known about the populational variation of stamen number in the species and whether one or more taxa are involved.</p>
