In the NCERT Class 11 Biology Chapter 5 Notes Morphology of Flowering Plants, 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 a unique succession. 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. Examples include jasmine.
