Inflorescence is a botanical term referring to the arrangement of flowers on a plant. It is the complete or partial flowering stem of a plant, including the flowers themselves and their associated bracts, if any. The arrangement can vary significantly between different plant species, and understanding inflorescence types is crucial for plant identification and classification.

There are two main types of inflorescences: racemose and cymose. In a racemose inflorescence, the main axis continues to grow and produce new flowers at its apex. The flowers typically open from the base upwards or from the outside inwards. Examples include spikes, racemes, and panicles. In contrast, a cymose inflorescence has a determinate growth pattern, where the main axis terminates in a flower, and further growth occurs from lateral buds. The flowers in a cymose inflorescence typically open from the center outwards. Examples include cymes and scorpioid cymes.

Other types of inflorescences include solitary flowers, which are not part of a larger cluster, and more complex arrangements like capitula (e.g., sunflowers) and spadices (e.g., calla lilies). The structure of an inflorescence can be influenced by factors such as the plant's genetics, environmental conditions, and pollination strategy. Studying inflorescences helps botanists understand plant evolution, reproductive biology, and ecological relationships.
