Answer:
An androecium is the third whorl of most flowers. It is made up of male reproductive units called stamens. A stamen has a long stalk called a filament. At the top of the filament is a cluster of microsporangia called the anther. Microsporangia produce microspores called pollen grains, which contain sperm cells.

Didynamous (stamens), having four stamens in two pairs,
Polyadelphous
Having stamens joined by their filaments into a number of clusters.
