Spike: The main axis elongated bearing sessile flowers, as in Verbena, Bottle-brash. Corymbose Raceme: Inflorescence corymbose in the flowering Stage but later on Becomes a simple raceme due to elongation of axis e.g., in Brassica. The pedicels of older flowers are longer than those of younger ones, so that all flowers lie at the same level, as in fibers (candytuft). Corymb: The main axis comparatively short. The pedicels of flowers are of the size, e.g., in Larkspur. The main axis may be elongated, shortened, or flattened into a Therefore the classification of Racemose Inflorescence is based on the Development of the main axis and pedicels of the flowers. There is an arrangement of flowers in them is centrifugal i.e., the young flowers are towards the periphery and the older ones towards the center. In a cymose inflorescence, the flowers usually form Clusters. The flowers develop in Basipetal Succession, i.e., the terminal flower is the oldest and the lateral ones are younger. One, two, or more lateral branches develop below the terminal flowers, each ending in a flower and producing daughter axes. Cymose Inflorescence: In this type of inflorescence, the main axis soon ends Flower. In such cases, the arrangement of flowers is Centripetal, i.e., the oldest flowers towards the periphery and the youngest ones towards the Centre. The main axis of a racemose inflorescence is sometimes may be compressed and flattened into a disc, bearing a cluster of flowers on its upper surface. The flowers are developed In acropetal Succession, i.e., the oldest flowers are towards the base of the inflorescence and the youngest ones towards the apex. Racemose Inflorescence: In this type of inflorescence the axis continues its growth until the last e flower is formed at its apex.
