Brassicaceae
From eagle-rock.org
Brassicaceae, a medium-sized and economically important family of flowering plants (Angiosperms), are informally known as the mustards, mustard flowers, the crucifers or the cabbage family.
The name Brassicaceae is derived from the included genus Brassica. Cruciferae, an older name, meaning "cross-bearing", describes the four petals of mustard flowers, which are reminiscent of a cross.
The family contains over 330 genera and about 3,700 species.
