Herbs annual, (10-)20-60(-75) cm tall. Stems erect, branched below and above, glabrous or sparsely pubescent at least basally. Basal leaves not rosulate; petiole (0.5-)1-4.5(-6) cm; leaf blade oblanceolate or oblong in outline, runcinate-pinnatisect, (1.5-)3-12(-15) × (0.5-)1-6(-9) cm; lateral lobes (1 or)2-6(-8) on each side of midvein, smaller than terminal, oblong or lanceolate, entire, dentate, or lobed. Uppermost cauline leaves smaller than basal, entire or 1-3-lobed. Fruiting pedicels divaricate or ascending, slender, much narrower than fruit, (5-)7-12(-20) mm. Sepals oblong, erect, 2-2.5 × 1-1.5 mm. Petals yellow, oblong-oblanceolate, 2.5-3.5(-4) × 1-1.5 mm; claw subequaling sepals. Filaments yellowish, erect, 2.5-4 mm; anthers oblong, 0.5-0.9 mm. Ovules 40-90 per ovary. Fruit narrowly linear, slender, terete, (2.5-)3-4(-5) cm × 0.9-1.1 mm, straight or slightly curved inward, younger ones overtopping flowers; valves glabrous, slightly torulose; style 0.2-0.5 mm; stigma prominently 2-lobed; septum membranous. Seeds oblong, 0.8-1 × 0.5-0.6 mm, inserted in depressions of septum. Fl. May-Aug, fr. Jun-Sep. 2n = 14.

Annuals; glabrous or sparsely pubescent. Stems erect, branched proximally and distally, (1-)2-6(-7.5) dm, glabrous or sparsely pubescent at least basally. Basal leaves not rosulate; petiole (0.5-)1-4.5(-6) cm; blade oblanceolate or oblong (in outline), (1.5-)3-12 (-15) cm × (5-)10-60(-90) mm, margins runcinate to pinnatisect; lobes (1-)2-6(-8) on each side, oblong or lanceolate, smaller than terminal lobe, margins entire, dentate, or lobed. Cauline leaves similar to basal; (distalmost) blade (smaller, to 2 cm wide), margins entire or 1-3-lobed. Fruiting pedicels divaricate or ascending, slender, much narrower than fruit, (5-)7-12(-20) mm. Flowers: sepals erect, oblong, 2-2.5 × 1-1.5 mm; petals oblong-oblanceolate, 2.5-3.5(-4) × 1-1.5 mm, claw 1-1.5 mm; filaments 2.5-4 mm; anthers ovate, 0.5-0.9 mm. Fruits (divaricate to ascending, young fruits overtopping flowers), narrowly linear, straight or slightly curved inward, slightly torulose, slender, (2.5-)3-4(-5) cm × 0.9-1.1 mm; valves glabrous; ovules 40-90 per ovary; style 0.2-0.5 mm; stigma prominently 2-lobed. Seeds 0.8-1 × 0.5-0.6 mm. 2n = 14.

Erect, to 6 dm, spreading-hairy below; lower lvs deeply pinnatifid with oblong to ovate, entire to dentate or angularly lobed segments, the upper lvs with fewer and smaller lobes; infl very contracted, the young frs elongating rapidly and projecting beyond the fls; sep 2–3 mm; pet 3–4 mm; anthers ca 0.7 mm; pedicels slender, divergent, 5–10 mm; frs linear, 2.5–5 cm; 2n=14, 28, 42, 56. Native of Eurasia, occasionally found in our range, and becoming a weed in the Pacific states. May, June. (Norta i.)

Annual, (10-)20-60 cm tall, erect, branched, glabrous or sparsely hairy with simple hairs. Basal and lower leaves petiolate, pinnately lobed with a hastate terminal lobe larger than the laterals, 2-6-jugate, very variable in size; cauline leaves similar but only 1-3-jugate. Racemes 50-80(-100)-flowered, up to 30 cm long in fruit with siliquae overtopping young flowers and buds. Flowers c. 3 mm across, yellow; pedicels (5-)10-15 mm long in fruit, filiform, ascending or sub-spreading, rarely spreading. Sepals 2-2.5 mm long. Petals (2.5-) 3-4 mm long, c. 1 mm broad, usually slightly longer than the sepals. Stamens c. 2:3 mm long; anthers c. 0.5 mm long. Siliquae (25-)30-45 mm long, 1 mm broad, linear, often slightly upcurved; valvex submembranous, convex, obscurely to distinctly torulose, faintly 3-veined but the mid-vein distinct, glabrous; style inconspicuous, thickened, with a depressed, sub-bilobed stigma; septum hyaline; seeds 20-40 in each locule, c. 1 mm long, oblong-ellipsoid, yellowish-brown.

Annual herbs 10-60 cm tall; glabrous or with short, appressed hairs, especially on young growth. Lower leaves runcinate-pinnatifid with 2-6 pairs of lateral lobes; lobes mostly toothed or somewhat lobed. Stem leaves upwards with gradually fewer, smaller, lateral lobes and a more prominent terminal lobe; upper leaves petiolate, simply hastate or with a few small, narrow, lateral lobes. Inflorescence ebracteate, very dense and contracted in flower; in fruit elongate, with the young fruits overtopping the flowers and buds. Flowers inconspicuous, the petals pale yellow, 2.5-3 mm long, hardly exceeding the sepals. Anthers 0.5-0.8 mm long. Siliquae 3-5 cm long, c. 1 mm in diameter, linear, straight or curved, ascending on slender pedicels 6-10 mm long; valves 3-nerved, glabrous, bulged by the seeds; stigma subsessile, 2-lobed. Seeds numerous (60-80), in 1 row, yellowish, less than 1 mm long.
