Calyx: The calyx is the outermost accessory set of floral leaves, consisting of sepals. Sepals are usually green inconspicuous bodies.

What are the parts of a flower?

In a typical flower there are four types of structures called floral leaves. These arc arranged in four whorls. Floral leaves are arranged on the swollen upper parts of flower stalk. The flower stalk is called pedicel and the swollen upper part is called Thalamus. In the thalamus are present nodes and highly reduced internodes.
