Mustard flowers typically have six stamens, with four tall and two short.
The fruit of a mustard plant is a specialized capsule with two valves. The fruit is usually dry and membranous, and may or may not split open naturally to release the seeds.
Mustard plants belong to the Brassicaceae family, also known as the Cruciferae.
The female reproductive part of the flower is the gynoecium, which consists of one or more carpels. Mustard has two carpels that are fused together.
