Annual or biennial herb, 30-80 cm, stems erect, simple and branched in the region of inflorescence or branched from base, glabrous or more commonly with a greyish indumentum of stellate and simple hairs below, glabrescent above. Basal leaves long-petiolate, 2- or 3-pinnatisect with linear segments; cauline leaves ± sessile, 2- or S-pinnatisect, rarely simply pinnatisect. Inflorescence long. Petals (2-)2.5-4 x 0.5-1 mm, pale yellow, slightly longer than sepals. Fruiting pedicels spreading or erect-ascending, (5-)10-15 mm. Fruit 13-35 x 0.5-1 mm, straight or slightly curved, ± torulose; style very short. Fl. 4-6. Waste places, 300-1700 m.

Widespread in Eurasia, N. Africa. Variable in most characters, especially leaf lobing. In some specimens the leaves are only simply pinnatisect. Differs from the European material in having the petals about twice as large. A complex species in which further investigation might reveal several recognisable taxa.
