1. The formation of leaves is initiated at the peripheral region of the apex
2. Leaf buttress results from activity of the peripheral zone
3. Plastochron is the period between the initiation of two successive leaf primordia
4. Maximal area is when volume and surface area of apical meristem is at maximum
5. Minimal area is when volume and surface area of apical meristem is at minimum
6. Leaf primordia results from frequent periclinal divisions by the tunica and corpus
7. Procambial strands give rise to the vascular tissues of leaves
8. Leaves are produced in regular order or arrangement based on their phyllotaxy
