Annual or biennial, (20-)30-120 cm tall, erect, branched, usually somewhat hispid below with simple, deflexed hairs, rarely glabrous. Basal and lower leaves lyrate-pinnatipartite, stalked; terminal lobe elongated, triangular to hastate; lateral lobes 2-4 paired, narrower; all lobes dentate; upper leaves ± similar but smaller, short-stalked to subsessile. Racemes 50-100-flowered, up to 30(-40) cm long in fruit. Flowers mediocre, 6-8 mm across, bright yellow; pedicels (6-) 8-12(-15) mm long in fruit, ascending,± upcurved, hardly or not thickened. Sepals 3-4 mm long. Petals 5-7 mm long, (2-)3-3.5 mm broad. Stamens 3-3.5: 4-4.5 mm long; anthers c. 1.5 mm long. Siliquae (15-)20-40(-50) mm long, 1 mm broad, linear-subcylindrical, erect, slightly upcruved; valves submembranous, slightly torulose, convex, 3-veined; style inconspicuous, c. 0.5(-1) mm long with subbilobed depressed stigma. septum hyaline; seeds (15-)25-30 in each locule, c. 1 mm long, oblong-ellipsoid, brown, somewhat papillose; radicle incumbent or oblique.

Fl. Per.: March June.

Type: Described from Europe 'Hab. in Borunia, Gedani, in montanis aequicolor' Herb. Linn. no. 836/40(LINN).

Distribution: Europe and most of Asia; introduced elsewhere.

A very polymorphic species. Some forms with smaller flowers and less dissected leaves reach very close to the previous species but siliquae not overtopping the young flowers and buds distinguishes it. Glabrous forms seem to be quite common in Baluchistan, and may become a troublesome weed.
