Biennials or perennials; (short-lived). Trichomes of leaves 2–5(–7)-rayed on adaxial leaf surface. Stems erect, unbranched or branched distally, 0.2–2.5(–3.5) dm. Basal leaves: blade (fleshy or not), spatulate, 2–10 cm × 5–15 mm, base cuneate, margins dentate, entire, or lobed, apex obtuse. Cauline leaves (distal) sessile or short-petiolate; blade margins entire or dentate. Racemes elongated slightly in fruit. Fruiting pedicels horizontal to divaricate, slender, narrower than fruit, 4–15 mm. Flowers: sepals oblong, 7–14 mm, lateral pair saccate basally; petals yellow, usually suborbicular, rarely obovate, 15–30 × 6–14 mm, claw 10–15 mm, apex rounded; median filaments 10–13 mm; anthers linear, 3–4 mm. Fruits widely spreading or divaricate, linear, straight, not torulose, 3–14 cm × 2–4 mm, terete when green, becoming latiseptate when dry, not striped; valves with obscure midvein, pubescent outside, trichomes (2 or) 3 or 4 (or 6)-rayed, glabrous inside; ovules 32–74 per ovary; style cylindrical, slender, 0.3–2 mm, sparsely pubescent; stigma 2-lobed, lobes as long as wide. Seeds oblong (compressed), 1.8–2.8(–3.5) × 1–2 mm; winged distally (wing narrow all around). 2n = 36.
