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.

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.
Six tepals, zygomorphic, six stamens, bilocular ovary, axile placentation.
Actinomorphic, polyphyllous, unilocular ovary, axile placentation.
Tricorpellary, actinomorphic, polyandrous, superior ovary, axile placentation.
Bisexual, zygomorphic, gamophyllous, inferior ovary, marginal placentation.
