The Genus Cochlearia comprises a group of plants commonly known as spoonworts or scurvy grasses, which are native to coastal regions of the Northern Hemisphere. Some synonyms for Genus Cochlearia include Lepidium, Rorippa, and Nasturtium, which are alternative names that have been used in the past. Lepidium, meaning 'scale-like', refers to the shape of the seeds of some species, while Rorippa means 'pondweed', which perhaps reflects the aquatic habitats of some members of the group. The name Nasturtium derives from the Latin 'nasus tortus', meaning 'twisted nose'. These synonyms are useful for identifying different members of this diverse group of plants.
