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.
