The flower is the most attractive and colourful part of the plant. A flower arises from the floral bud on the stem and is attached to the axis by a structure called a pedicel. The pedicel continues to form a slightly swollen tip called the thalamus.

The pistil is the female reproductive structure in a flower that has different parts such as style, stigma and ovary. The sterile, nonfunctional and abortive pistil present in staminate flower is called pistillode. It has a simple, reduced structure and function.

In an inflorescence or cluster of flowers, a pedicel is a short flower stalk. Pedicels are used to expose flowers to the sun and breeze, as well as to position them in such a way that their perfume and colour attract pollinating insects more easily.
