Biennials or perennials; (short-lived); often glaucous, glabrous or pubescent. Stems branched, (0.9–)1.3–7(–12) dm, (somewhat glaucous, glabrous throughout or pubescent basally). Basal leaves: petiole (0.7–)2–8.5 cm, ciliate; blade usually oblanceolate to spatulate, rarely obovate or lanceolate, (1.5–)2.2–15(–25) cm × (6–)10–35(–50) mm, margins often pinnately lobed to lyrate, sometimes dentate or entire. Cauline leaves sessile; blade linear to lanceolate, smaller distally, (base sagittate or auriculate, appressed to stem), margins usually entire, rarely dentate. Racemes dense, elongated in fruit, (flower buds narrowly oblong). Fruiting pedicels erect to erect-ascending, (appressed to rachis at least basally), straight or slightly curved, slender, (1.5–)2–5(–10) mm, not flattened at base. Flowers: sepals erect to ascending, oblong to linear-oblong, (3–)3.5–6(–8) × (0.8–)1–1.8(–2) mm; petals white to lavender, linear to narrowly oblanceolate, (6–)6.5–11(–14.5) × 0.5–0.7(–1) mm, margins strongly crisped, claw differentiated from blade, (slender, 2–4 mm, narrowest at base); nectar glands surrounding bases of lateral stamens, median glands absent; filaments subequal, (2.5–)4.5–8.5(–10.5) mm; anthers exserted, linear to narrowly oblong, 2–3.5(–4.5) mm, circinately coiled, (apiculate); gynophore 0.5–1.5(–3.5) mm. Fruits divaricate to ascending, torulose, straight or slightly curved, terete, (0.6–)1–2.5(–4.2) cm × 0.7–1(–1.8) mm; ovules 22–50 per ovary; style cylindrical, 0.5–1.5(–2.5) mm. Seeds (flattened), 1–1.5(–1.7) × 0.5–0.7(–1) mm. 2n = 26.
