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).

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.
