Book Description
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.

Book Description
Field Guide to the Grasses of Oregon and Washington is an illustrated guide to all 376 species, subspecies, and varieties of grasses--both native and introduced--that grow wild in Oregon and Washington. It also has broad applicability in neighboring states and provinces. Grasses are important functional components in a variety of ecosystems and are highly valued for habitat restoration in numerous habitats, ranging from wetlands to deserts, and from sea level to alpine. They are important weeds and are also cultivated as ornamentals. This guide covers the entire spectrum of grasses from weedy invaders to rare native species. Identifying grasses can be challenging. The grass family is one of the most diverse plant families in the region, and differences between species can be both subtle and minute. This guide provides identification keys, species descriptions, photographs of each species (both in the field and through a microscope), habitats, and range maps. Users will especially appreciate the macrophotographs that illustrate hard-to-see, diagnostic features. Biologists, land managers, botanists, and consultants, as well as plant professionals, home gardeners, and amateur plant enthusiasts, will find this guide an indispensable reference for identifying all the grasses they encounter in the diverse habitats of Oregon and Washington.
