  • Slide 6
  • Placentation Parietal Axial Free Central
  • Slide 7
  • Number of carpels 1. Lines on the outside of the pistil 2. One stigma lobe per carpel 3. Number of locules (if not free central
  • Slide 8
  • Flower Symmetry:
  • Slide 9
  • Inflorescence Types arrangement of flowers on the flowering stem Solitary - one flower per peduncle Terminal: Axillary:
  • Slide 10
  • Inflorescence Types arrangement of flowers on the flowering stem Many Flowered - More than one flower per inflorescence spike: Raceme:
  • Slide 11
  • Inflorescence Types arrangement of flowers on the flowering stem Many Flowered - More than one flower per inflorescence Panicle: Much branched Corymb: Outer flowers oldest
  • Slide 12
  • Inflorescence Types arrangement of flowers on the flowering stem Many Flowered - More than one flower per inflorescence Cyme: Middle flowers oldest Umbel: All come of Peduncle apex
  • Slide 13
  • Inflorescence Types arrangement of flowers on the flowering stem Many Flowered - More than one flower per inflorescence Head: Dense, rounded with many sessile flowers
  • Slide 14
