Bear in mind when considering this book that it is a _survey_ compilation, not an identification guide. It sets out to catalog the astounding variety of succulents worldwide, and never touches on care or maintenance. Pictures are often of salient features, such as flowers or stem structures, rather than of the entire plant, and many are photographed in their native habitat (by which I mean, they are not always the flawless beauties that we are accustomed to seeing in plant books --although the settings are often as fascinating as the plants themselves!).
I very much enjoy thumbing through this book. Although I personally find it of very little practical value, I would recommend it to any plant enthusiast with an appreciation for diversity or photography.
