Rorippa is a flowering plant genus in the cabbage family (Brassicaceae), containing approximately 80 species native to Europe through central Asia, Africa, and North America. Rorippa species are annual to perennial herbs, usually with yellow flowers and a peppery flavour.

Rorippa formerly included several species of watercress, now placed in the genus Nasturtium. In particular, R. nasturtium-aquaticum (now N. officinale) and R. microphylla (now N. microphyllum) are often referred to as species of Rorippa.

Roripa (etymology unexplained) ; originally spelled Rorippa, but later emended by its author. Cruciferae. Here are included the plants long known as Nasturtium (but not the garden flowers of that name, which belong in Tropaeolum), and by some later botanists as Radicula. By a ruling of the International Botanical Congress at Brussels, however, the name Radicula is not permissible as it is based on a morphological character; therefore, the plants are transferred (at least temporarily) to Roripa. Under Roripa, the species become R. Nasturtium, Rusby (Sisymbrium Nasturtium-aqudticum, Linn. Radícula Nasturtium-aquaticum, Brit. & Rend.), the water-cress; R. Armoracia, Hitchc. (Radiada Armoracia, Rob.), the horse-radish; R. indica, Bailey (Sisymbriumindicum, Linn. Nasturtiumindicum, DC.), the tropical cress. The above text is from the Standard Cyclopedia of Horticulture.
