You can never have too many wildflower identification books. I find that photos in some books don't always show the plant from an angle that shows all the details of leaves and flower. This book does feature full page color photos (about 100 of these) and supplements them with drawings that may show different stages of the plant (berries or a related plant).

The arrangement in this book is by plant families and includes descriptions that are useful aids in identification. The authors based the book on field work ranging from New Hampshire to Virginia.

There's a glossary at the end, but I think some flower diagrams naming the parts would have helped me understand what the glossary was defining.
