Calotropis is a genus of flowering plants in the dogbane family, Apocynaceae, first described as a genus in 1810. It is native to southern Asia and North Africa. They are commonly known as milkweeds because of the latex they produce. Calotropis species are considered common weeds in some parts of the world. The flowers are fragrant and are often used in making floral tassels in some mainland Southeast Asian cultures. Fibers of these plants are called as madar or mader. Calotropis species are usually found in abandoned farmland. Lotus is Nelumbo nucifera. Jasmine is Jasminum sp. Oleander is Nerium sp.

The flower is considered as the modified shoot that is meant for reproduction and contains the reproductive organs stamen (male reproductive part) and pistil (female reproductive part) and after fertilization, its parts convert into fruits and vegetables as a result of reproduction.

Carpels, pistil or gynoecium are the female reproductive part of the flower that consists of a stigma that holds the pollen grains, the style that leads the path of pollen tube and ovary produce small structures called ovules or ovum (female gamete).
