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.

simple (single)
2)  compound, 
3)  mixed, and
