This book is designed for B.Sc. (Gen.) and B.Sc. (Hons.) students. All important genera are discussed, giving details of structure, anatomy, and the developmental stages of reproductive organs from different sections, such as Bryophytes, Pteridophytes and Gymnospersm. The paleobotany section deals with important fossil genera from Pteridophytes and Gymnospersm. Comparisons of different genera are provided. Experimental studies of Bryophytes, Pteridophytes and Gymnospersms are also discussed. The book is amply illustrated with diagrams.
