Calyx is the outermost whorl of the flower and are called sepals.
Sepals are green, leaf like and protect the flower in the bud stage.
The calyx may be gamosepalous (sepals free) or polysepalous (sepals united).

Aestivation
Imbricate aestivation is found in papilionaceous family.
Generally sepals are green, leaf like and protect the flowers in the bud stage.
In cymose type of inflorescence, the main axis terminates in a flower, hence is limitless in growth.
In axile placentation ovary is one chambered but it becomes two cambered due to formation of the false septum.

It is the female reproductive part of the flower.
It is composed of stamens.
Stigma is usually at the tip of the style and is the receptive surface for pollen grains.
Each ovary bears one or more ovules attached to a flattened, cushion like placenta.
