Available in PDF, EPUB and Kindle. Book excerpt: From the Preface. In 1901 our Morphology of Spermatophytes, Part I, was published, which comprised a presentation of the gymnosperms. It had grown out of a special course given to graduate students for several successive years, and although most of the ground had been traversed in this way several times, the larger part of the material in the book was taken from the contributions of other investigators. There was some new material included, but the chief contributions of the book were certain illustrations and the organized presentation of the group as a whole for research students. During the last decade the special course referred to has been continued for successive generations of graduate students, with a constantly widening range of material and from new points of view. In addition to this extensive and repeated critical examination of material, a number of special investigations have been carried on in the laboratory. These investigations have been planned so that there might be not only a research contact with all regions of the gymnosperm series, but also a clearing up of unknown or doubtful forms. These special contributions from the laboratory have aggregated twenty-six since 1901, and have dealt with fourteen genera, distributed as follows: in Cycadales, Dioon, Microcycas, Encephalartos, Ceratozamia, and Zamia; in Ginkgoales, Ginkgo; in Coniferales, Pinus, Thuja, Torreya, Phyllocladus, Podocarpus, and Dacrydium; in Gnetales, Ephedra and Gnetum. This has enabled us to present the living groups from an entirely different standpoint, and to use many illustrations prepared in this laboratory. The present account, therefore, is based upon our own work, supplemented by the work of other investigators, rather than a compilation from literature, supplemented by occasional personal observations. Furthermore, the last decade has been one of unprecedented activity in the investigation of gymnosperms, as a comparison of the bibliography of the volume of 1901 with that of the present one will indicate. In this period the number of titles has increased from 112 to 420, some of the additions being accounted for by the larger inclusion of paleobotanical material. Aside from a far more complete knowledge of the living groups, including as it does now at least the salient facts in reference to almost every genus, there have been two notable advances. In the first place, during this period vascular anatomy has developed as a subject of first importance, and some of its most conspicuous contributions have been in connection with the origin and relationships of gymnosperms. In the second place, paleobotany has brought to light during the last decade more facts of importance in reference to the history of gymnosperms than in reference to any other group of plants. This has enabled us to treat of the extinct groups in a way that was impossible ten years ago...

Download or read book A Natural History of Conifers written by Aljos Farjon and published by Timber Press. This book was released on 2008-01-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compelling account of the extraordinary relatives of ordinary garden conifers. Leading expert Aljos Farjon provides a compelling narrative that observes conifers from the standpoint of the curious naturalist. It starts with the basic question of what conifers are and continues to explore their evolution, taxonomy, ecology, distribution, human uses, and issues of conservation. As the story unfolds many popular misconceptions are dispelled, such as the false notion that all conifers have cones. The extraordinary diversity of conifers begins to dawn as Farjon describes the diminutive creeping shrub Microcachrys tetragona, whose strange seed cones resemble raspberries, and the prehistoric-looking Araucaria meulleri. The taxonomic diversity of conifers is huge and Farjon goes on to relate how, over the course of 300 million years, these trees and shrubs have adapted to survive geological upheavals, climatic extremes, and formidable competition from flowering plants. All who seek to learn more about the early history of life on our planet will cherish this book.
Download or read book Early Flowers and Angiosperm Evolution written by Else Marie Friis and published by Cambridge University Press. This book was released on 2011-08-18 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent discovery of diverse fossil flowers and floral organs in Cretaceous strata has revealed astonishing details about the structural and systematic diversity of early angiosperms. Exploring the rich fossil record that has accumulated over the last three decades, this is a unique study of the evolutionary history of flowering plants from their earliest phases in obscurity to their dominance in modern vegetation. The discussion provides comprehensive biological and geological background information, before moving on to summarise the fossil record in detail. Including previously unpublished results based on research into Early and Late Cretaceous fossil floras from Europe and North America, the authors draw on direct palaeontological evidence of the pattern of angiosperm evolution through time. Synthesising palaeobotanical data with information from living plants, this unique book explores the latest research in the field, highlighting connections with phylogenetic systematics, structure and the biology of extant angiosperms.
Download or read book Phylogeny and Evolution of the Angiosperms written by Douglas Soltis and published by University of Chicago Press. This book was released on 2018-01-24 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.
