Orange flower with large stamen The stamen (plural stamina or stamens) is the pollen-producing reproductive organ of a flower. A stamen typically consists of a stalk called the filament and an anther which contains microsporangia. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle portion. The sterile tissue between the lobes is called the connective. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium in various species of plants form a great variety of patterns, some of them highly complex. It surrounds the gynoecium and in turn the perianth, if there is one, surrounds the androecium. A few members of the family Triuridaceae, particularly Lacandonia schismatica, are exceptional in that their gynoecia surround their androecia.
