Each stamen which represents the male reproductive organ consists of a stalk or a filament and an anther.
An actinomorphic flower can be dissected into two equal halves from any plane.
Superior ovary is found in hypogynous flowers.
When stamens are attached to the petals, they are epiphyllous as in brinjal.
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).
