Characteristics of Pteridophyta
Pteridophyta is predicted as an oldest 
Cormophyta. 
Cormophyta is plant having real roots, stems, and leaves. Its means that the roots, stems, and leaves have vascular bundle, so 
Pteridophyta also known as 
Tracheophyta. Fossil of 
Pteridophyta found in the stone since carbon era past of 345 millions ago.
 Pteridophyta
Pteridophyta lives in water (hydrophyte), in moist area (hygrophyte), sticking in other plant (ephiphyte), or living in residue/ waste of other plant (saprophyte). 
Pteridophyta is not produce seeds but it produces spores. Spores are produced by leaves, usually in under surface of leaves. The young leaves are roll up. Stems of 
Pteridophyta located under of soil called rhizome. From rhizome will grow the roots like a hair called fibrous roots and also grow leaves stalk. There are any stems of 
Pteridophyta that grow up upper of soil, for example is Plant-fern (Cyathea sp.).
