The books are magnificent. The brief species desciptions with a focus on diagnostic characters are very informative and the excellent photos are a treat!
"The books are stunningly beautiful. The amount of information on conifers in general in Volume 1 is amazing. The photography is the about the best I've ever seen. In a single word: Brilliant! Please convey my deepest thanks to the authors and the editor for what was obviously a work of passion."
