Racemose Inflorescence:
Racemose inflorescence refers to the type of inflorescence where the main axis continues to grow and produces flowers laterally on pedicels of equal length. It is characterized by an indeterminate growth pattern where the terminal bud does not convert into a flower. The flowers in a racemose inflorescence are arranged in an acropetal succession, meaning the oldest flowers are present at the base, and the youngest ones are found at the apex.

Features of Racemose Inflorescence:
1. Indeterminate Growth: In racemose inflorescence, the main axis continues to grow, resulting in the production of flowers along the axis.
2. Lateral Flowers: The flowers are borne laterally on pedicels of equal length, creating a zigzag pattern.
3. Acropetal Arrangement: The flowers are arranged in an acropetal manner, with the oldest flowers located at the base and the youngest ones at the apex.
4. Absence of Terminal Flower: Racemose inflorescence lacks a terminal flower, as the main axis does not terminate in a flower.
5. Continuous Growth: The inflorescence can continue to grow indefinitely, producing new flowers as the axis elongates.

Types of Racemose Inflorescence:
1. Raceme: In a raceme, the main axis produces pedicellate flowers, with the oldest flowers at the base and the youngest flowers at the apex.
2. Spike: A spike is similar to a raceme, but the flowers are sessile or nearly sessile. The main axis elongates, and the flowers are arranged in an acropetal manner.
3. Panicle: A panicle is a branched raceme where the main axis produces secondary branches, each bearing pedicellate flowers. The arrangement of flowers is similar to a raceme.
4. Corymb: In a corymb, the pedicels of the lower flowers are longer than those of the upper flowers, resulting in a flat-topped or slightly convex shape.
5. Umbel: An umbel consists of flowers that arise from a common point and have nearly equal length pedicels, creating a flat or convex arrangement.
6. Spadix: A spadix is a fleshy spike with small unisexual flowers crowded on a thick, fleshy axis. It is typically surrounded by a bract-like structure called a spathe.

Cymose Inflorescence:
Cymose inflorescence refers to the type of inflorescence where the main axis terminates in a flower, and further growth is inhibited. It is characterized by a determinate growth pattern. In cymose inflorescence, the terminal bud converts into a flower, resulting in a limited number of flowers arranged in a centrifugal manner.

Features of Cymose Inflorescence:
1. Determinate Growth: Cymose inflorescence follows a determinate growth pattern, where the main axis terminates in a flower, and further growth is inhibited.
2. Terminal Flower: Unlike racemose inflorescence, cymose inflorescence possesses a terminal flower

Racemose: In racemose types of inflorescence, the main axis grows continuously and flowers are present laterally on the floral axis. Flowers are present in an acropetal manner.

Cymose: In the cymose type of inflorescence, the main axis does not grow continuously. A flower is present terminally on the main axis. The flowers are borne in a basipetal order. The main axis has limited growth.
