Anatomy of Anther | Palynology - Biology Discussion

The parietal cells undergo a series of periclinal and anticlinal divisions to form two to five concentric layers of anther wall [endothecium, middle wall layers (three layered) and outer tapetum]. The L3 layer gives rise to the connective, vascular bundle, and circular cell cluster adjacent to the stomium.
