I. Cohesion of Androecium:

  • When stamens are united with each other, it is called cohesion of androecium. It is of following three types:
  1. Adelphous: The stamens are fused by their filaments only. The anthers are free. When the fusion of filament produces a single group, it is called monadelphous, e.g., Hibiscus. When two groups are formed, it is called diadelphous, e.g. pea. When many groups are produced, it is called polyadelphous, e.g., Citrus.
  2. Syngenesious/Synantherous: Stamens are fused by anthers only. Filaments are free. E.g., sunflower.
  3. Synandrous: Stamens are fused both in the region of filaments and anthers. E.g., cucumber.
