what is a stamen

A stamen is the male reproductive organ of a flower, which produces pollen. It typically consists of a long, slender stalk called the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures called microsporangia that produce pollen for pollination. The stamens in a flower are collectively called the androecium. The number and arrangement of stamens, as well as the way in which the anthers release pollen, are important taxonomic characteristics for many flowering plants. The presence of numerous stamens is common in many plant families, while most orchids possess only one stamen.
