How to draw a typical flower

A typical angiospermic flower consists of four sets of members arranged in four whorls viz the calyx, the corolla, the androecium and the gynoecium or Pistil. Of these, calyx and corolla are known as accessory or non-essential whorls, because they have only secondary role in reproduction such as protection of flower in bud condition and attraction of insects for pollination. The androecium and gynoecium constitute  the reproductive or essential whorls as they are involved in the production of male and female gametes and seed formation.

The stalk on which flower is borne is called the Pedicel. The pedicel is swollen at its apical end. The swollen tip of the pedicel is called the thalamus or receptacle. All floral whorls arise from the thalamus.

Draw stalk of the flower with sepals as shown.

Draw Pistil as shown on receptacle.

Draw stamens on either sides of pistil.
