  4. Trees and Shrubs Roots Trunk (Main Stem) Crown (Lateral Branches + Leaves + Reproductive Units)

  5. Leaves • All leaves originate as primordia at the apex of a stem

  6. Variation in Leaves • Number of leaflets • Venation • Pattern of attachment on stem

  7. Leaves • At maturity, most leaves have a stalk (petiole) and a flattened blade (lamina) with a network of veins (vascular bundles).

  8. Leaves • Simple (single blade) • Compound (divided into leaflets). • Palmately compound leaflets attached at the same point at end of petiole • Pinnately compound leaflets in pairs along the rachis • Bipinnately compound leaflets subdivided further
