Question:What are androecium?
Answer:The androecium is the male part of an angiospermic flower which is composed of two or more stamens. They are called essential organs because the androecium is involved in reproduction. In Fabaceae, the stamens are 10, diadelphous and anthers are dithecous. Diadelphous stamens are those which are united by their filaments so as to form two groups.
