Good introductory book on palms (has only about 100 palms in it, and there are 10x that number in cultivation in the US), but definitely tilted towards the east coast point of view. So if you live in Florida, or Texas or any other southeast coast state, the comments on cultivation and diseases are very useful. However, if you live in California, you need to take the cultivational information lightly as much of it does not apply. Photos are excellent and large. The authors are experts in the field of palm biology. ANd the disease section is excellent showing what the diseases look like.
I found this book on a trip to San Diego. I was fascinated by the different palm species and I needed a book to identify them. I brought it with me to Florida two years later where it was exceptionally helpful. Each palm listed has an immense amount of information about size, cultivation requirements, hardiness, and many other characteristics. It also has great pictures of each species. An excellent reference.
