This book seems very promising in the beginning. In fact the first third is very good, wherein Tudge explains the evolution of trees themselves and of different groups of trees. In the second part of the book, Tudge attempts to talk about every taxonomic group of trees. The problem is that his scope is too wide. There is not enough detail as he talks about each group. For instance, when talking about a particular group fo conifers, he refers to their "unique cones"---without saying what makes them unique. This lack of detail persists throughout the latter two-thirds of the book. There is not much to learn from this latter portion, and it is very disappointing when compared the first part.
