- - - - Seed ferns(extinct),Gymnosperms- Progymnosperms (extinct), Angiosperm
  - - - Heterospory
      - Megasporangium enclosed in integuments
      - Retention of megaspores w/in megasporangium
      - Reduction # of megasporocytes/ megasporangium to 1
      - Survival of 1 megaspore
      - Endosporic megagametophyte
      - Modification of megasporangium apex for microspores or microgametophytes
      - Embryo develop within megagametophyte
