Book Description
The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

Book Description
This exciting new textbook examines the concepts of evolution as the underlying cause of the rich diversity of life on earth-and our danger of losing that rich diversity. Written as a college textbook, The Diversity and Evolution of Plants introduces the great variety of life during past ages, manifested by the fossil record, using a new natural classification system. It begins in the Proterozoic Era, when bacteria and bluegreen algae first appeared, and continues through the explosions of new marine forms in the Helikian and Hadrynian Periods, land plants in the Devonian, and flowering plants in the Cretaceous. Following an introduction, the three subkingdoms of plants are discussed. Each chapter covers one of the eleven divisions of plants and begins with an interesting vignette of a plant typical of that division. A section on each of the classes within the division follows. Each section describes where the groups of plants are found and their distinguishing features. Discussions in each section include phylogeny and classification, general morphology, and physiology, ecological significance, economic uses, and potential for research. Suggested readings and student exercises are found at the end of each chapter.

Book Description
Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.

Book Description
Angiosperms, or flowering plants, are one of the most diverse plant groups on the planet, and they offer tremendous resources for a broad range of industries. Flowering Plants examines the anatomy and morphology of angiosperms with a focus on relating their metabolic activities to products for the pharmaceutical, food, cosmetic, and textile industries. This up-to-date reference provides a thorough understanding of plant structure and chemical and molecular processes found in angiosperms. It covers many important topics on applied botany, and therefore, can also be used as a textbook for students of related fields. It details the latest research in the field, along with areas in need of further study, for students, researchers, and professionals working in industry. The book takes advantage of technological innovations to showcase a range of advanced techniques for studying plant structure and metabolites, such as cryo-electron microscopy, ultramicroscopy, x-ray crystallography, spectroscopy, and chromatography. Filled with helpful illustrations, diagrams, and flowcharts to aid comprehension, Flowering Plants offers readers the morphological, anatomic, and molecular knowledge about angiosperms they need for a range of industrial applications.

Book Description
The central theme of Green Plants, first published in 2000, is the astonishing diversity of forms found in the plant kingdom, from the simplicity of prokaryotic algae to the myriad complexities of flowering plants. The book is arranged according to generally accepted classification schemes, beginning with algae (prokaryotic and eukaryotic) and moving through mosses, liverworts, fern allies, ferns and gymnosperms to flowering plants. Copiously illustrated throughout, it provides a concise account of all algae and land plants, with information on topics from cellular structure to life cycles and reproduction. The authors maintain a refreshingly cautious approach in discussions of possible phylogenetic relationships and include newly emerging information on features of plants known only as fossils. This edition has been completely updated to reflect current views on the origin of the major groups of plants, providing a resource for students of botany, and for researchers needing a comprehensive reference to the plant kingdom.
