Bougainvillea

Close up of bougainvillea flower centered on the stamen.

All the stamens of a flower are collectively called the androecium (plural androecia) this is sometimes referred to as the male part of the flower although strictly speaking only the gametes are male or female. A stamen consists of a filament and an anther. The anthers consist of four fused chambers called microsporangia. It is in these chambers that the pollen is produced which contains the male gametes and must be transferred to the pistil for fertilisation to take place. Some flowers bear only stamens and are sometimes referred to as male flowers, the correct term however is staminate.
