Herbs annual or biennial, rarely short-lived perennial, (5-)15-50(-70) cm tall, glabrous or sparsely pilose. Stems erect, simple at base, simple or branched above, not flexuous. Basal leaves not rosulate, often withered by anthesis; petiole to 3.5 cm; leaf blade pinnatisect, with 1-4 lateral lobes on each side of midvein; terminal lobe subreniform, suborbicular, rhomboid-ovate, or broadly obovate, much larger than lateral ones, (1-)1.5-2.5 × 0.7-2 cm, repand, crenate, or 3-5-lobed; lateral lobes petiolulate or subsessile, oblong, ovate, or suborbicular. Cauline leaves similar to basal ones; petiole to 3 cm, base not auriculate; lateral lobes 1-5 on each side of midvein, much smaller than terminal lobe; terminal lobe (0.7-)2-5(-6.5) × (0.5-)1.5-4(-5) cm, repand, crenate, or coarsely 3-5(-7)-lobed. Racemes with a straight rachis. Fruiting pedicels divaricate or ascending, (0.3-)0.6-1.4(-1.8) cm, slender. Sepals oblong, 1.5-2.5(-3) × (0.7-)0.9-1.4 mm. Petals white, spatulate, 2.5-4.5(-6) × (1-)1.5-2.5 mm. Stamens 6; filaments 2-3.5 mm; anthers ovate, 0.3-0.6 mm. Ovules 20-40 per ovary. Fruit linear, (0.9-)1.5-2.8(-3.5) cm × (0.8-)1-1.4 mm; valves glabrous or rarely sparsely puberulent or pilose, torulose; style (0.3-)0.6-1.5 mm. Seeds brown, oblong or subquadrate, 0.9-1.5 × 0.6-0.9 mm, narrowly margined or not. Fl. Apr-Jul, fr. May-Aug. 2n = 32.
