Biennials. Trichomes of leaves mostly 3- or 4-rayed, 2-rayed ones usually on stem and pedicel. Stems erect, often branched distally, (slightly ribbed), (1–)3–9(–11) dm. Basal leaves (withered by fruiting; petiole 1–4 cm); blade elliptic-oblong or oblanceolate, (1–)2–6(–8) cm × (0.3–)5–10 mm, base cuneate, margins entire or obscurely denticulate, apex acute. Cauline leaves sessile or subsessile; blade (linear or elliptic-linear), margins entire or obscurely denticulate. Racemes considerably elongated in fruit. Fruiting pedicels suberect or ascending, slender, narrower than fruit, (3–)4–8(–10) mm. Flowers: sepals oblong, 4–7 mm, lateral pair not saccate basally; petals yellow, obovate, (6–)7–9(–10) × 2–3 mm, claw 5–8 mm, apex rounded; median filaments 4–6 mm; anthers oblong, 1.5–2 mm. Fruits erect, (often appressed to rachis), linear, straight, somewhat torulose, (1–)1.5–2.5(–4) cm × 1–1.3 mm, 4-angled, not striped; valves with prominent midvein, pubescent outside, trichomes 3- or 4-rayed, fewer 2-rayed ones, usually glabrous inside, rarely sparsely pubescent; ovules 40–60 per ovary; style cylindrical, slender, 0.5–2 mm; stigma capitate, entire. Seeds oblong, 1–1.5 × 0.4–0.6 mm; not winged.
