Ferns and Fern Allies

Ferns and their allies are very ancient plants. They were present at the time of the dinosaurs, before any of the flowering plants arose.

Ferns and their allies can be distinguished from other plants by two simple characteristics. First, unlike true mosses and in common with flowering plants, these are vascular plants. That is, they have specialized woody tissue used to transport water through out the plant. This allows them to live in areas with variable moisture and to grow taller than mosses.

Second, like mosses, these plants reproduce by means of spores and not seeds. In ferns and fern allies, spores germinate to form free living plants (the prothallus) that function as flowers. These, in turn, give rise to the mature plants we recognize.
