Vascular Plants of the Pacific Northwest, in five parts, offers the first complete guide, with keys, to the ferns, fern-related, and seed-bearing plants of Washington, northern Oregon, Idaho north of the Snake River plains, the mountainous western part of Montana, and southern British Columbia. Each volume gives complete regional synonymy, type collections, geographic ranges, “genuine” common names, and chromosome numbers for each species, as well as economic importance and horticultural features.Part 1 covers vascular cryptogams, often referred to as “ferns and fern allies”; gymnosperms; and monocotyledons. An unusual feature is the inclusion of a key to the species of grasses based upon vegetative features, as well as one to grass genera based primarily upon floral structures. Part 1 also includes several sections relating to the work as a whole: an Index to Plant Families, a Glossary, a key to aquatic plants based mainly on vegetative features, several pages of additions and corrections, and a general index to common, generic, and specific names.Illustrated by Jeanne R. Janish.

Each volume gives complete regional synonymy, type collections, geographic ranges, “genuine” common names, and chromosome numbers for each species, as well as economic importance and horticultural features.Part 2 covers the Salicaceae through the Crassulaceae. Each species is illustrated by one to several detailed drawings at considerable magnification of such structures as the flower, fruit, and seed, as well as a habit sketch, mostly at one-half natural size. Two keys to the families of Dicotyledonae covered by Parts 2 to 5 are included. In the first, the families are initially separated into orders, largely on the basis of floral morphology, then keyed apart. The second key, which is completely artificial, utilizes such peculiarities of the various taxa as habitat, habit, duration, and foliage, as well as floral morphology. As in Parts 3 and 4, notes on the ornamental value of the trees, shrubs, and many herbs, were written in collaboration with Brian O. Mulligan, director of the University of Washington Arboretum, and Carl S. English, well-known botanist and horticulturalist.Illustrated by Jeanne R. Janish.

Astralagus, the largest genus and one of the most difficult, is treated by one key based on characteristics of the flower and by another based on characteristics of the fruit.Illustrated by Jeanne R. Janish.

Since this volume includes many of the plants most useful as ornamentals, gardeners, both amateur and professional, will be interested in the comments concerning species suitable for cultivation in rockery, woodland, and moist or general garden areas.Illustrated by Jeanne R.

Attention is given to an ecological view of the species, emphasizing the concept of interaction of environment and plant population and the evolution within the latter of distinct ‘ecotypes.’Part 5 is illustrated by John H. Rumely. All other volumes are illustrated by Jeanne R. Janish.

Flora of the Pacific Northwest, first published in 1973, became an instant classic for its innovative style of providing species descriptions in the identification keys and for its comprehensive illustrations of nearly all treated taxa (species, subspecies, and varieties). Students rely on it as an essential primer, while veteran botanists and natural resource managers use it as the definitive reference for the region’s flora.This completely revised and updated edition captures the advances in vascular plant systematics over the decades since publication of the first edition. These advances, together with significant changes in plant nomenclature, the description of taxa new to science from the region, and the recent documentation of new native and nonnative species in the Pacific Northwest required a thorough revision of this authoritative work.Flora of the Pacific Northwest covers all of Washington, the northern half of Oregon, Idaho north of the Snake River Plain, the mountainous portion of western Montana, and the southern portion of British Columbia. It accounts for the wild-growing native and introduced vascular plants falling within those boundaries and includes:Treatment of 5,545 taxa (more than 1,000 taxa added from the first edition)Illustrations for 4,716 taxa (1,382 more than the first edition)Nomenclature changes for more than 40 percent of the taxa included in the first editionThese enhancements make this new edition the most comprehensive reference on Pacific Northwest vascular plants for professional and amateur botanists, ecologists, rare plant biologists, plant taxonomy instructors, land managers, nursery professionals, and gardeners.

This study of the vascular plant taxa in this region includes keys, descriptions, habitats, distributional data, and pertinent synonymy to every vascular species without cultivation in the southeastern United States. The Asteraceae is the largest family of flowering plants in the temperate zone and numbers over fifteen thousand species. Although one of the easiest families to recognize, many genera have been poorly defined heretofore. Geographical Range Vascular Flora of the Southeastern United States covers the forested region of the southeastern United States west to the prairie and north to the southernmost terminal moraines. This region includes Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Arkansas, Tennessee, Kentucky, and West Virginia. Notation of presence in adjacent states of Texas, Oklahoma, Missouri, Illinois, Indiana, Ohio, Pennsylvania, and New Jersey will be made. |Examining a wide range of published and unpublished documents--including sermons, official statements from various churches, denominational papers and periodicals, and letters, diaries, and newspaper articles--Rable illuminates the broad role of religion
