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 edition
These 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.
