The definitive reference for botanists, horticulturists, foresters and conservationists - this second edition has been fully revised, and provides the most authoritative listing of conifer names through to the year 2000, with extensive information on distribution, conservation status and a bibliography of the most relevant scientific literature.
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.
"What are the lives of trees, of conifers, like'. . . How do seedlings establish and develop into saplings? How do some seedlings stay alive for decades, marking time in the deep shade of the forest? How do the distinctive forms of saplings of the different species arise'. . . When, how, and where do cones come from? What is the sex life of a conifer? Where does pollen come from? What does pollen do?" - From the Introduction A comparative account of the coniferous trees indigenous to Northeastern North America Extensively illustrated with full-colour photographs, diagrams, and drawings by the author, Graham R. Powell's Lives of Conifers examines the complex and fascinating life cycles of the 12 coniferous trees that grow naturally in northeastern North America on both sides of the Canada-U.S. border. Tracing their development from seeds and seedlings, to saplings, through the pole stage to maturity, old age, and death, the book is designed to pro-vide a comparison of each species at each stage of life, thus aiding in the recognition and identification of species at all stages of their existence. It includes descriptions of developmental processes and how they differ among the species. The species covered in the book are: the balsam fir, eastern hemlock, tamarack larch, eastern white pine, jack pine, pitch pine, red pine, black spruce, red spruce, white spruce, eastern juniper, and eastern thuja. The book is based almost entirely on what is visible to the careful observer in the forest, and includes only the parts of trees that can be seen above ground. Lives of Conifers will appeal to forest scientists, forestry students, foresters, forest technologists, botanists, horticulturists, arborists, naturalists, and general readers interested in knowing more about their natural surroundings.
The new edition of this work first published in 1990 includes 3,787 references to the published literature. To make it far more accessible, many more general titles have been added including coverage of Araucariaceae, Cupressaceae and Pinaceae and subjects related to their taxonomy.
Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.
