It is designed with the non-specialist in mind: trees are arranged in color-coded groups based on easy-to-observe leaf and stem characters. Each species account is illustrated with at least one full-color photograph of the plant's most readily identifiable part or parts, as well as an image of the full tree, and a distribution map shows its range. The concise text also touches on the practical uses of plants; supplementary features include useful notes on tree identification and an extensive illustrated glossary. Authoritative, classic guide written by leading experts includes comprehensive photography for all species, showing both close-up details and full trees and carefully designed keys to enable accurate identification.
