Biennials or perennials; (short-lived); distinctly glaucous throughout, glabrous. Stems usually branched distally, 1–4.4 (–6) dm. Basal leaves (and proximal cauline): petiole 1–4 (–6) cm; blade (fleshy), usually ovate or obovate, rarely orbicular or spatulate, (2.2–) 4–10.5 (–14) cm × (10–) 15–43 (–55) mm, margins usually lyrate, sinuate and repand, or dentate, rarely entire. Cauline leaves shortly petiolate; blade lanceolate or elliptic, much smaller than basal, margins entire or repand. Racemes somewhat lax, slightly elongated in fruit. Fruiting pedicels divaricate to divaricate-ascending, straight or incurved, slender, 4–12 (–15) mm, slightly flattened at base. Flowers: sepals spreading to reflexed, oblong, (2.5–) 3–4 × (0.8–) 1–1.5 (–1.8) mm; petals purple or lavender, usually oblanceolate, rarely spatulate, (2.5–) 3–4.5 × 0.5–1 mm, margins not crisped, claw differentiated from blade; nectar glands confluent; filaments subequal, 2.5–3.8 mm; anthers oblong, 1–1.8 mm; gynophore 0.5–0.8 (–1) mm. Fruits usually erect to ascending, rarely divaricate, torulose, straight or, sometimes, incurved, flattened, (2–) 4–7.4 cm × 1–1.5 (–1.8) mm, (replum not constricted between seeds); ovules 32–44 per ovary; style subclavate, 0.5–1.2 (–1.5) mm. Seeds (0.7–) 1–1.5 × 0.5–0.8 mm.
