In Class 11 Biology, inflorescence refers to the arrangement of flowers on the floral axis. It is mainly of two types:  

1. Racemose inflorescence – The main axis continues to grow and flowers are borne laterally in an unique succession (younger flowers at the top and older ones at the base). Examples include mustard and wheat.  

2. Cymose inflorescence – The main axis terminates in a flower, and subsequent growth occurs from lateral buds, with flowers arranged in a basipetal order (older flowers at the top and younger ones at the base). Examples include jasmine and dianthus.
