Stamens are the male reproductive organs of flowers. Typically, a stamen is made up of a pollen-producing anther borne on a filament. Pollen arises in four sporogenous regions within the anther. The sporogenous cells are surrounded by nutritive support cells, the tapetum. Mature pollen is released from the anther by dehiscence of the anther wall.
