A fascinating overview of many interesting tree species from all over the world. 
The author tried to remain very unbiased when discussing the causes of many issues the trees have with regards to their survival, namely deforestation caused by European explorers and settlers. A rather romantic view of European botanists was presented too, which is understandable when the book was wrote with the Gardens at Kew involved. I personally would have preferred a harsher criticism of this, as it is the actions of our ancestors that have dramatically reduced many tree populations to where they are, and while modern Kew is vital for the regeneration of tree species, it was originally part of the problem.
