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.
