Developed in consultation with botanists from The Royal Botanic Gardens, Kew, and Cornell University's renowned Bailey Hortorium, it separates species into two fundamental types: conifers and broad-leaved, then organizes them into genera based on common characteristics, presenting each in its presumed order of evolution. Major differences between species groups are explained, with advice on which parts of a tree to examine when a closer look is required.
More than 1,000 annotated illustrations depict the height, shape, foliage, buds, and seed of each species, with trees bearing a strong resemblance shown side by side to highlight their differentiating characteristics. The accompanying text and system of symbols provide the important details on features and habitat essential to quick, reliable identifications. Graphical keys indicate genus and species, listing both scientific and common names. The guide also includes a map charting tree hardiness and distribution based on widely recognized climactic zones, general information about individual species traits and history, a glossary, and more.
