Lepidium is a genus of plants in the mustard/cabbage family, Brassicaceae. The genus is widely distributed in the Americas, Africa, Asia, Europe, and Australia.[1] It includes familiar species such as garden cress, maca, and dittander. General common names include peppercress, peppergrass, and pepperwort. Some species form tumbleweeds.[2] The genus name Lepidium is a Greek word meaning 'small scale', which is thought to derived from a folk medicine usage of the plant to treat leprosy, which cause small scales on the skin. Another meaning is related to the small scale-like fruit.[3]
