'This is truly a magnum opus by a world expert on the conifers and it has been fascinating, enjoyable and informative to read. It is based on the extensive travels of the author to everywhere that arborescent conifers grow. This has enabled the author to illustrate it with a wonderful collection of his personal and most informative photos of the conifers of the world. The text is a skilful combination of data from Palaeobotanic, molecular and field observations that show the history, evolution and contemporary status of this vitally important group of plants. It is the author's personal experience with each genus and familiarity with so much of the literature about conifers that makes this such interesting reading. There is no doubt that this book will remain a classic on the subject for many years to come.' Sir Ghillean Prance, FRS, former Director of the Royal Botanic Gardens, Kew
