Herbs annual or biennial, (7-)15-40(-65) cm tall, glabrous throughout or sparsely pubescent below, often slightly glaucous. Stems erect, simple at base, branched above. Leaves strongly dimorphic. Basal and lowermost cauline leaves with petioles (0.5-)1-2(-4) cm; leaf blade 2-or 3-pinnatifid or-pinnatisect, (1-)3-8(-15) cm; ultimate lobes linear or narrowly oblong. Upper cauline leaves sessile; leaf blade broadly ovate, cordate, or suborbicular, (0.5-)1-3(-4) × (0.5-)1-2.5(-3.5) cm, base deeply cordate-amplexicaul, margin entire, apex acute. Fruiting pedicels divaricate, 3-5(-7) mm, slender, straight, glabrous, terete. Sepals yellowish green, oblong, 0.8-1(-1.3) × 0.5-0.8 mm. Petals yellow, narrowly spatulate, 1-1.5(-1.9) × 0.2-0.5 mm, base attenuate to a claw ca. 0.5 mm. Stamens 6; filaments 0.6-0.9 mm; anthers 0.1-0.2 mm. Fruit rhombic or orbicular, 3-4.5(-4.8) × 3-4 mm narrowly winged distally; wings apical, 0.2-0.4 mm; apical notch to ca. 0.3 mm; style 0.1-0.3 mm, as long as or shorter than apical notch. Seeds dark brown, ovate, 1.6-2(-2.3) × 1.2-1.4 mm, narrowly winged all around; cotyledons incumbent. Fl. Mar-Jun, fr. May-Jul. 2n = 16.
Annuals or biennials; (glaucous), glabrous or sparsely pubescent proximally. Stems simple from base, erect, branched distally, (0.7-)1.5-4.3(-5.6) dm. Basal leaves rosulate; petiole (0.5-) 1-2(-4) cm; blade 2-or 3-pinnatifid or pinnatisect (lobes linear to oblong), (1-)3-8(-15) cm, margins entire. Cauline leaves sessile; blade ovate to cordate or suborbicular, (0.5-)1-3 (-4) cm × (5-)10-25(-35) mm, base deeply cordate-amplexicaul, not auriculate, margins entire. Racemes considerably elongated in fruit; rachis glabrous. Fruiting pedicels divaricate-ascending to horizontal, straight, (terete), 3-6(-7) × 0.2-0.3 mm, glabrous. Flowers: sepals oblong, 0.8-1(-1.3) × 0.5-0.8 mm; petals pale yellow, narrowly spatulate, 1-1.5(-1.9) × 0.2-0.5 mm, claw 0.5-1 mm; stamens 6; filaments 0.6-0.9 mm, (glabrous); anthers 0.1-0.2 mm. Fruits orbicular to rhombic or broadly obovate, 3-4.5 (-5) × 3-4.1 mm, apically winged, apical notch 0.1-0.3 mm deep; valves thin, smooth, not or obscurely veined, glabrous; style 0.1-0.4 mm, subequaling or slightly exserted beyond apical notch. Seeds (dark brown), ovate, 1.6-2(-2.3) × 1.2-1.4 mm. 2n = 16.
Annual or biennial herb; stems erect, 20–40 cm high; hairs simple, setulose, sparse. Leaves dimorphic; basal shape leaves petiolate, bi-to tri-pinnate, up to 10 cm long, pubescent; cauline leaves reducing to sessile, broadly ovate to cordate, entire, auriculate with overlapping lobes, glabrous. Inflorescence an elongating raceme. Sepals c. 1 mm long, spreading, sparsely setulose, delicate pink. Petals narrowly spathulate, c. 1.5 mm long, yellow. Stamens 6. Style as long as or exserted from shallow, apical notch. Silicula broadly elliptic, 3–4 mm diam., glabrous, the slight wing very narrow above, slightly emarginate. Seeds ovoid, 1.7–2 mm long, compressed with wing-like margin; radicle incumbent.
