The stamen is the male organ of a flower. Typical flowers have six stamens inside a perianth (the petals and sepals together). Each stamen consists of a thin stalk called a filament supporting an anther that contains the microsporangia. Haploid pollen — the male gamete cells of a flowering plant — are produced by the microsporangia.
