To approach this book, we must already know a bit about plants, at least some of them by name, and know some great families. If this is the case, this book is really quite exciting. Clear, precise, it is full of examples that one never forgets. Therefore, every weeds emerging from fallow slope become a show and you tell a story. I loved plants and nature but with this book, there is a little over 10 years, I really became a botanist. Single flat, the sketches are accurate but in black and white and we would gain with a renovated and colorful edition. A must read for every apprentice botanist.
