  1. Stipules
    An outgrowth at the base of the petiole
  2. Types of stipules
    • Glandular
    • Sheathing
    • Foliar
    • Protective
    • Spinose
  3. Lateral Buds
    Located at sides of stem

    • Collateral
    • superimposed
  6. Lenticels
    • Small openings where bark has been pushed up so gases can be exchanged into and out of the stem, for transpiration and respiration.
    • Oxygen enters stem and carbon dioxide and water vapor exit. Bark cells need oxygen to survive.
