The Inflorescence

The stem holding this whole reproductive portion of a plant is called a peduncle.

The major axis above the peduncle called rachis bears the flowers or secondary branches. Also, each flower stalk in the inflorescence is referred to as a pedicel.

Types of Inflorescence

Based on the mode of branching of the main axis or peduncle, the main groups of inflorescences are: 

simple (single)

2)  compound, 

3)  mixed, and 

4)  special
