Summary: best field guide for identification
Review: this book along with "edible wild plants:a north american field guide" by thomas elias and "a field guide to medicinal plants and herbs: of eastern and central north america" by james a. duke will provide all the information necessary for positive identification. cross referencing the various photos and other information leaves no doubt.
