--><span class="statement" id="st-undefined" data-properties="">Annuals; hispid basally, subglabrate or glabrous distally. <b>Stems</b> erect or ascending, usually branched distally, 1–8 dm, sparsely hispid basally. <b>Basal</b> leaves rosulate; petiole 0.3–3 cm; blade oblanceolate, 0.7–9 cm × 4–25 mm, margins coarsely dentate-sinuate. <b>Cauline</b> leaves (median) sessile; blade lanceolate to narrowly ovate, 0.5–11 cm × 2–45 mm, (smaller distally, base amplexicaul), margins entire or denticulate. <b>Racemes</b> (densely flowered), with a terminal cluster of sterile flowers. <b>Fruiting</b> pedicels ascending to divaricate, 3–18(–27) mm, pubescent or glabrous. <b>Flowers</b>: sepals erect to ascending, (dark purple in bud, becoming greenish or creamy white and purplish or brown distally), ovate to narrowly lanceolate, 6–17 × 2.5–3.5 mm (subequal, keeled, usually glabrous, rarely pubescent, trichomes simple); petals white (with dark purple veins), 8–20 mm, blade 4–8 × 1.5–2 mm, crisped, claw oblanceolate, 4–11 × 2–3 mm; filaments in 3 unequal pairs, (median pairs often connate), abaxial pair 3.5–11mm, lateral pair 2–7 mm, adaxial pair 5–12 mm; anthers oblong to linear-oblong, unequal, 1.5–4 mm, (adaxial pair smaller). <b>Fruits</b> erect or ascending (often straight), terete or slightly latiseptate, 5–12 cm × 2.5–3.5 mm; valves each with prominent midvein basally; ovules 52–72 per ovary; style 0–4 mm; stigma strongly 2-lobed (lobes 1–4 mm, opposite valves). <b>Seeds</b> 2–3.5 × 1.7–2.2 mm. <b>2n</b> = 28.</span><!--

--><p>Both R. C. Rollins (1993) and R. E. Buck (1995) treated <i>Caulanthus lemmonii</i> as a variety of <i>C. coulteri</i>, whereas E. B. Payson (1923) treated the two as independent species. The differences between them clearly justify their separate recognition. In fact, those differences are far greater than those that distinguish the minor color form “barbarae” that both Rollins and Buck recognized as a distinct variety of <i>C. amplexicaulis</i>. The types of both <i>C. coulteri</i> and <i>C. lemmonii</i> are quite distinct. The slight intergradation between the two taxa, especially in occurrence of branched trichomes and lobing of cotyledons, most likely resulted from hybridization, but that needs to be verified experimentally and molecularly.</p>
