The Pteridophytes are the spore-bearing plants and are distinguished from the other cryptogams by the possession of the vascular tissues--xylem and phloem. They are commonly called "Vascular Cryptogams." The present publication includes various types of Pteridophytes prescribed in the syllabi of several Indian Universities. Many standard books and journals have been drawn upon for the diagrams and all the life histories are profusely illustrated and supplemented with the latest information on the subject.
