Plants in this Division have crude stems and Seeds: structure formed by the maturation of the ovule in seed plant; in fact the seeds represent a portion of the life cycle involving 3 generations of plants (mother sporophyte, megagametophyte, and new sporophyte or embryo). Leaves closely appressed to divergent and scale like; can be dimorphic with scale and awl shaped leaves.

Heterospory has never resulted in dioeciousness in the sporophyte in pteridophytes, while it is so in many gymnosperms. Instead of roots, they have "rhizoids." Both groups use pollen to facilitate fertilization, though angiosperms have an incredible diversity of pollination strategies that are not found among the gymnosperms. Male gametes are ciliate in pteridophytes, while they are not in gymnosperms (except for few like cycas). A smaller group than the cryptogams, the gymnosperms comprise 15 families, 70-80 genera, and about 820 species. the Greek word gymnosperma, meaning The term cryptogams (kruptos= hidden, gamos= wedded) was suggested by Linnaeus in 1754 for all non-flowering plants that reproduce by means of spores and do not produce seeds.
