The cauline leaves are much reduced and are short petiolate to sessile but not auriculate-clasping. The inflorescence is a raceme made up of yellow flowers having four petals. The fruit is a silique 3-5 cm long with a beak 1-2 cm long that is flattened-quadrangular. The valves of the silique are glabrous or rarely bristly, three to five nerved. The seeds are smooth 1-1.5 mm in diameter.Wild mustard is highly invasive and has been reported to be poisonous to livestock. It is eaten by the caterpillars of some Lepidoptera, such as the Small White (Pieris rapae). It contains chemicals of the class glucosinolates, including sinalbin.
