This book proved completely useless as it was unable to help me in identifying some of the most common plant species (google did a better job), I mean really? A few of the most dominant species in the area were nowhere to be found in the book. The pictures did no justice either because they either showed just the flowers or just leaves. A whole picture of the plant would be nice for the amateur identifier. This book successfully embarrassed me in front of my friends. I was supposed to be real cool and identify the plants along our trail, instead we spent countless minutes frantically searching and coming to no real conclusions about what any plant was. I do not recommend this book to anyone.
