Pteridophyta constitutes the earliest known vascular plants. 2. A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores.Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. c) amphibians of the plant kingdom. Engler (1909) included the Bryophyta and Pteridophyta under Embryophyta. As the first true land plants, they offer a very favourable material for the study of various adaptations that have made the colonization of land possible for the plants. The Cryptogamia was further divided into Thallophyta. and 78° 45’- 81° and 1' E long. It covers the entire course of reading on the subject for B.Sc and M.Sc degrees.

An informative, innovative and comprehensive text on the subject, the second revised edition of the book offers a coherent account of various aspects of pteridophyta, in the light of new findings. Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes. As they produce neither flowers nor seeds, they are referred to as Cryptogams.
