I bought this book to use on our most recent trip to the Alpujarras in Southern Spain. I'm a total novice when it comes to wild flowers, so the colour coded arrangement of the book was a real help. I managed to identify the majority of what I saw whilst out on walks, with one or two exceptions. But that is probably the price you pay for a book that is small enough to fit in a pocket.
Verdict - A great compact field guide for a beginner, or for someone more experienced but new to the Mediterranean area.
