🔑Concepts
Inflorescence is defined as the arrangement of flowers on the floral axis, also known as the .
Based on whether the apex gets converted into a flower or continues to grow, inflorescences are classified into two major types: and .
In type inflorescences, the main axis continues to grow ( growth) and flowers are borne laterally in an succession (older flowers at the base, younger flowers at the tip).
In type inflorescences, the main axis terminates in a flower, hence has limited growth ( growth). Flowers are borne in a order (older flowers at the top, younger flowers at the base).
Special types of inflorescence include (found in , looking like a single flower), (found in ), and (found in species like Fig and Banyan).

💡Examples
Problem 1:
Identify the type of inflorescence where the main axis ends in a flower and the flowers follow a basipetal arrangement. Provide an example.
Solution:
The inflorescence is .
Explanation:
In inflorescence, the growth of the main axis is terminated by the production of a flower. Subsequent flowers arise from lateral branches below. An example of this is the or Jasmine.
Problem 2:
Differentiate between the arrangement of flowers in Mustard and Radish compared to .
Solution:
Mustard and Radish exhibit inflorescence, while exhibits inflorescence.
Explanation:
In Mustard (), flowers are produced in an succession on a continuously growing axis. In , the axis growth is limited and terminates in a flower, which is characteristic of the pattern.
