Pteridophytes And Gymnosperms

This encyclopedia offers access to the diversity of ferns and seed plants, the most important groups of green land plants. Available information of general and systematic relevance is synthesized at the level of families. Evidence from virtually all disciplines important to modern taxonomy makes the work a most valuable source of reference not only for taxonomists, but for all who are interested in the various aspects of plant diversity. A revised classification includes a complete inventory of genera along with their diagnostic features, keys for identification, and references to the literature. The first volume deals with pteridophytes and gymnosperms.

Most family entries include anatomy and morphology, including pollen morphology; reproductive biology; karyology; affinities, distribution and ecology; and a key to the genera.

The present book is designed for B.Sc. (Gen.) and B.Sc. (Hons.) students of all Indian university. The book is amply illustrated with diagrams. Almost all important genera are discussed giving details of structure, anatomy, developmental stages of reproductive organs from different sections like Bryophytes, Pteridophytes and Gymnospersm. Paleobotany section deals with important fossil genera from Pteridophytes and Gymnospersm. Various comparisons of different genera are given in all sections. Experimental studies of Bryophytes, Pteridophytes and Gymnospersms are discussed from recent literature.

This second volume of the magnificent compendium exhaustively describes and classifys the ferns, fern allies, and gymnosperms of North America. Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.

The Gymnosperms is a well-illustrated comprehensive account of living and fossil plants of this group. Chapters 1 and 2 give a general account, and describe similarities and dissimilarities with pteridophytes and angiosperms. Chapter 3 deals with classification. The next 18 chapters (4-21) deal sequentially with fossil and living taxa. Phylogenetic relationships are considered for each order. Chapter 22 discusses the in vitro experimental studies on the growth, development and differentiation of vegetative and reproductive organs and tissues. Chapter 23 summarizes the economic importance of gymnosperms. Chapter 24 gives the conciuding remarks. Thus, there is a complete coverage of significant findings concerning morphology, anatomy, reproduction, development of embryo and seed, cytology, and -evolutionary trends and phylogeny. Ultrastructural and histochemical details are given wherever considered necessary. There is a comprehensive list of literature citations, and a plant index. This book is essentially meant for the postgraduate students in India and abroad. Undergraduate students can also use it profitably. The entire course should be taught in 25-30 lectures/hours and about 75 hours of field and laboratory work.

"Packer and Gould have provided an invaluable service for anyone interested in western North American botany by creating a simple, user-friendly and portable key to the Alberta species found in the 30-volume set of Flora of North America. Designed to be carried into the field for handy reference and use, this work incorporates the new names and taxonomical understandings that have accumulated over the years. Part 1 of what will be a three-volume set contains the up-to-date classification of the ferns, fern allies, gymnosperms, and monocots found in Alberta according to the latest taxonomic findings."--
