− | 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 Radic- ula under which name they are described atpage 2895. 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. | + | Roripa (etymology unexplained) ; originally spelled Rorippa, but later emended by its author. Cruciferae.
