in botany: A genus of plants belonging to the class of didynamia, and to the order of angiospermia; and in the natural system clasped with those the order of which is doubtful. The calyx is spreading, and divided into five parts, almost to the base. The corolla is divided into five parts in the same manner, which are rounded, equal, spreading, and of the length of the calyx. The stamens grow in pairs at a distance from each other. The capsule is compressed, orbicular, bilocular, the partition being transverse.—There are two species, the europaea and evoeolacea. The europaea, or bastard moneywort, is a native of South Britain. The leaves of it are slender, and creeping. The leaves are small, round, and notched. The flowers grow under the wings of the leaves, are small, and of a pale red colour. It blossoms from July to September, and is found in Cornwall on the banks of rivulets.
