Northwestern Wild Berries by Ted Underhill (1979, Paperback)

This book is an excellent source book for identifying berries in the western US and Canada. Includes color photo of both berries and leaves. Description of plant, most with spring & fall descriptions. Some have a history of the plant and it's name. Also rated for edible, non-edible, and poisonous. Also has ideas for using plants (jellies, pies, etc.) Very concise, helpful book. I highly recommend it.
