Download or read book Flowering Plants Dicotyledons written by Klaus Kubitzki and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume - the first of this series dealing with angiosperms - comprises the treatments of 73 families, representing three major blocks of the dicotyledons: magnoliids, centrosperms, and hamamelids. These blocks are generally recognized as subclasses in modern textbooks and works of reference. We consider them a convenient means for structuring the hundreds of di cotyledon families, but are far from taking them at face value for biological, let alone mono phyletic entities. Angiosperm taxa above the rank of family are little consolidated, as is easily seen when comparing various modern classifications. Genera and families, in contrast, are comparatively stable units -and they are important in practical terms. The genus is the taxon most frequently recognized as a distinct entity even by the layman, and generic names provide the key to all in formation available about plants. The family is, as a rule, homogeneous enough to conve niently summarize biological information, yet comprehensive enough to avoid excessive re dundance. The emphasis in this series is, therefore, primarily on families and genera.
Download or read book Flowering Plants written by Armen Takhtajan and published by Springer Science & Business Media. This book was released on 2009-07-06 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Microspores Evolution and Ontogeny written by S. Blackmore and published by Academic Press. This book was released on 2016-04-20 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the processes of plant reproduction is increasingly important in the exploitation of plant resources. Microspore formation is a major event in the life cycles of land plants, allowing the transition from diploid sporophyte generation to the haploid gametophyte generation, and varies greatly between taxa in the diversity of processes involved. Despite the wealth of information available, there are very few sources which bring together the results of research work on the reproduction in all the major plant groups.**Microspores fills this gap by reviewing microsporogenesis from a systematic and evolutionary perspective in groups ranging from algae to angiosperms. Special chapters focus on structure, function, cell and molecular processes, and potential biotechnological applications of plant spores and pollen. The result is an up-to-date guide to the applications of modern techniques in the classic area of botany.**This work bridges several disciplines to provide a coherent and authoritative account which will be essential reading for research scientists and lecturers in botany, evolution, ultrastructure, reproductive and developmental biology, and palynology.

Download or read book Annual Plant Reviews The Evolution of Plant Form written by Barbara A. Ambrose and published by John Wiley & Sons. This book was released on 2012-11-21 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Evolution of Plant Form is an exceptional new volume in Wiley-Blackwell’s highly successful and well established Annual Plant Reviews. Written by recognised and respected researchers, this book delivers a comprehensive guide to the diverse range of scientific perspectives in land plant evolution, from morphological evolution to the studies of the mechanisms of evolutionary change and the tools with which they can be studied. This title distinguishes itself from others in plant evolution through its synthesis of these ideas, which then provides a framework for future studies and exciting new developments in this field. The first chapter explores the origins of the major morphological innovations in land plants and the following chapters provide an exciting, in depth analysis of the morphological evolution of land plant groups including bryophytes, lycophytes, ferns, gymnosperms and angiosperms. The second half of the book focuses on evolutionary studies in land plants including genomics, adaptation, development and phenotypic plasticity. The final chapter provides a summary and perspective for future studies in the evolution of plant form. The Evolution of Plant Form provides essential information for plant scientists and evolutionary biologists. All libraries and research establishments, where biological and agricultural sciences are studied and taught, will find this important work a vital addition to their shelves.
Download or read book Evolutionary Trends in Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1991 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Takhtajan, one of the foremost authorities on flowering plant evolution, has brought together from the literature and his own studies interpretations of the origin and evolution of various vegetative and reproductive parts of flowering plants. Starting with growth habit, he continues through leaf and stem structure, including the origin of vessels, sieve tubes, and rays, to flowers. After tracing the possible origin of the flower, he discusses in detail the sepals, petals, stamens, and carpels, accounting for their variations in number of parts, fusion, position, and structure. The evolution and origin of the micro- and megagametophytes and the development of triple fusion are considered. The book ends with the developmental sequence of the fruit and seed types. Each chapter has its own extensive bibliography. Takhtajan has produced a book that will be essential in the library of any college where plant evolution is considered.-C. T. Mason Jr., University of Arizona--Choice Reviews.

Download or read book Morphology Development and Systematic Relevance of Pollen and Spores written by Michael Hesse and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Palynology, the science of fossil and recent spores/pollen grains, is of high importance, both in many pure and applied fields of the natural sciences (e.g. in botany, geology, climatology, archeology and medicine). It is not only an auxiliary science, but can certainly stand for itself. The "classical" palynology subjects, pollen morphology and systematics, are at present influenced by many modern approaches, e.g. from cell biology, analytical electron microscopy, morphometry, up to com- puter-aided-design of threedimensional reconstruction. In recent years fascinating informations have come to light, and new insights have given rise to changing scientific concepts. During the XIV International Botanical Congress, held in Berlin in 1987, a symposium was devoted to important topics of (actuo)palynology. Nine of its innovative, major contributions are presented in this volume. They cover the comparative morphology and the systematic/evolutionary significance of pollen/spores in critical taxa, aspects of pollen development (cytoskeleton), the substructure of sporopollenin, homologies between wall strata of ferns, gymnosperms and angiosperms, and important (but so far underrated) physical aspects of harmomegathy and pollen transport (fluid versus solid mechanics).
Download or read book Ontogeny and Systematics written by Christopher John Humphries and published by Columbia University Press. This book was released on 1988 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of short stories focuses on the Scottish civil war of 1644-45, in which the Marquis of Montrose led his royalist forces in a series of stunning victories against the odds before his final defeat at Philiphaugh. Each of Hogg's five tales centres on one of the five major battles of Montrose's brilliant but ultimately futile campaign. Each tale is utterly different from the others in genre and tone, but taken together they build up a composite picture of what it was like to experience the 'anarchy and confusion' of the time at first hand.
