Download or read book The Gymnosperms written by Chhaya Biswas and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This book offers a global synthesis of gymnosperm families, fossil and extant, providing a new and distinctive perspective on the macroevolutionary biodiversity trends within this group through their 375 million-year history. The stratigraphic ranges of the 84 gymnosperm families are plotted according to their first and last appearances in the fossil record. Also included is a systematic coverage of floral kingdoms, biodiversity patterns, insect associations and other fields, traced period by period from the Devonian to Quaternary.

Download or read book Pteridophytes and Gymnosperms written by K.U. Kramer and published by Springer Science & Business Media. This book was released on 1990-09-28 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Dawn Angiosperms written by Xin Wang and published by Springer. This book was released on 2017-08-02 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the controversial and conflicting hypotheses on the origin of angiosperms, which was generally assumed to be restricted to the Cretaceous and later ages. Since publishing the first edition of “The Dawn of Angiosperms” in 2010, several important advances have been made in this field of science, namely 1) the discovery of new fossil angiosperms from the Jurassic; 2) European researchers discovering angiosperm-like pollen from the Triassic; and most importantly 3) the discovery of a perfect flower from the Jurassic. All of these findings are at odds with the currently widely accepted evolutionary theories, and thus call upon us to critically reassess botanical theory. Accordingly, the new edition of this book not only includes more new fossil taxa, but also documents them in greater detail and corrects many commonly held misconceptions. In so doing, it makes related studies and teaching on the early history of angiosperms more realistic, concrete, and tangible, providing concrete fossil evidence as the basis for future research, and helping to distinguish the most accurate botanical hypotheses.
