Description:  "Herbs annual, (20-) 40-120 (-160) cm tall. Stems erect, branched above, sparsely to densely hirsute near base, glabrous or subglabrous above. Basal leaves rosulate; petiole 1-10 (-15) cm; leaf blade broadly oblanceolate, oblong or lanceolate in outline, pinnatisect, pinnatifid, or runcinate, (2-) 5-20 (-35) x (1-) 2-8 (-10) cm; lateral lobes (3 or) 4-6 (-8) on each side of midvein, smaller than terminal one, oblong or lanceolate, entire, dentate, or lobed. Uppermost cauline leaves with narrowly linear to filiform lobes. Fruiting pedicels divaricate or rarely ascending, stout, nearly as thick as fruit, (4-) 6-10 (-13) mm. Sepals oblong, cucullate, ascending or spreading, 4-6 x 1-2 mm. Petals yellow, spatulate, (5-) 6-8 (-10) x 2.5-4 mm; claw subequaling sepals. Filaments yellowish, erect, 2-6 mm; anthers oblong, 1.5-2.2 mm. Ovules 90-120 per ovary. Fruit narrowly linear, stout, terete, (4.5-) 6-9 (-12) cm x 1-2 mm, usually straight; valves glabrous, smooth; style subclavate, 0.5-2 mm; stigma prominently 2-lobed; septum slightly thickened. Seeds oblong, 0.8-1 x 0.5-0.6 mm, inserted in depressions of septum"  (Flora of China online).

"Annual herbs; stems 3-15 dm long, loosely branched above, usually hirsute toward base, the hairs simple.  Lower leaves pinnately lobed, the lobes oblong and dentate, gradually changing upward on the plant to leaves with linear to filiform, entire segments.  Pedicels straight, widely spreading; sepals often yellow-tinged, 3.5-5 mm long; petals pale yellow, fading white, 6-9 mm long.  Siliques linear, terete, straight, 5-10 cm long, nearly equaling the pedicels in diameter, glabrous.  Seeds oblong, ca. 1 mm long, wingless"  (Wagner et al., 1999; p. 413).
