(Science: botany) Any plant of the genus Tropaeolum, geraniaceous herbs, having mostly climbing stems, peltate leaves, and spurred flowers, and including the common indian cress (Tropaeolum majus), the canary-bird flower (T. Peregrinum), and about thirty more species, all natives of south America. The whole plant has a warm pungent flavor, and the fleshy fruits are used as a substitute for capers, while the leaves and flowers are sometimes used in salads.
