"There can be no other word to describe this book than the term 'encyclopaedic.' Its 640 pages, 86 tables and 182 well-chosen illustrations provide a veritable mine of information and from an interdisciplinary point of view. It can, without any reservation, be recommended for its unexcelled presentation of material valuable for environmental conservation specialists..."
Richard Evans Schultes, Botanical Museum of Harvard University in Journal of Ethnobiology
"a carefully structured and well-presented textbook that makes a special effort to provide students with starting poits for additional studiesbecause of its very readable style, this book will interest students to really think about plant evolution in a broad sense rather than simply learn facts."
