Brassicaceae

Brassicaceae or Cruciferae, also known as the crucifers, the mustard family or cabbage family is a family of flowering plants (Angiospermae). The name Brassicaceae is derived from the included genus Brassica. Cruciferae is an older name, it means "cross-bearing", because the four petals of their flowers are reminiscent of a cross. According to ICBN Art. 18.5 (Vienna Code) both Cruciferae and Brassicaceae are regarded as validly published, and are thus accepted as names for the family.
