Wetland Plants of Oregon and Washington

Although the author is admittedly part of the vibrant botany research community in the Corvallis-Eugene area, many of the species found in Western Oregon are found also in similar habitats in Western Washington and far NW Calif. Very few, if any, plants are described for east of the Cascades. The range for the book is clearly stated in the introduction. Note that as a wetland delineator, I find it to be excellent for a field reference for many typical wetland and fringe species. For specific identification, though, a flora such as Hitchcock's _Vascular Plants of the Pacific Northwest_ (5 vol. set) or the abbreviated _Flora of the Pacific Northwest_ is more appropriate.
