It is obvious that this book is primarily for avid readers and that it probably should not people who are looking for general information as texts, while being perfectly accessible to all, are rather scientific.
Only flaw in my opinion, the paper quality is not at the rendezvous.
This is a book to have in his library and complements two other equally excellent works. This is Biology and The Origins of plants: Volume 1, Ancient plants botany of the XXI century.
