There are two primary divisions of flowering plants or Phanerogams— (i) Gymnosperms, including the pines, firs, cedars, yews, etc., characterized by having the ovules naked, that is, not contained within an ovary. In the members of this group fertilization is direct, the pollen coming di- rectly in contact with ovule. (2) Angiosperms. The majority of flowering plants are included in the present division, characterized by.
