The flowers are radially symmetrical and the Latin family name Cruciferae describes the cross-like appearance of the 4 petals. There are 4 sepals and usually 6 stamens, 2 shorter than the other 4. The flowers are in racemes or branched clusters. The leaves are usually simple but may be pinnately compound. The seedpods are often long and slender but may be broad or oval, and are perpendicular to the stem to nearly upright. The sap may have a peppery taste.

Cabbages, turnips and radishes are members of the mustard family.
