Probably one of the best field guides for Texas wildflowers. I've used this book for many years and it has never failed me. Identification is made easy by categorizing plants by their bloom color. Makes it very easy for the novice to identify. Large pictures are placed on the left page with details on the facing page. Descriptions are sectioned by Bloom Period, Description, Habitat and additional Notes. The state is broken down into 9 habitat zones with each plant noting which zone it grows in. A plate at the front of the book shows a map of Texas broken down into these zones. The only small drawback is that the plant must be in bloom as some of the pictures do not show the leaf form but most people are not going to wonder if they don't see a flower. I highly recommend this book for anyone who has ever seen a wildflower in Texas and wondered what it is they are seeing.
I have had this book for about two years now. I love it! One of the most useful aspects of the book is that it is divided in to sections by the color of the bloom - ingenious! This has been so incredibly helpful in identifying wild flowers - I wouldn't have had the faintest idea of where to start looking in a book without this feature.
