The fifth edition of North American Trees continues the tradition established by the earlier editions, creating a comprehensive, readable reference designed for the general public and beginning student. The book covers nearly all North American trees (north of Mexico and tropical Florida) in technically useable detail.
This edition features:

• updated nomenclature
• Simplified terminology
• expanded information on natural history
• Additional Keys
• More background information on genera and families

Introductory material discusses the scope and arrangement of the guide, basic characters used in tree identification, highest classification categories of trees, information on identifying unknown trees, and keys to identifying trees. The rest of the manual is devoted to descriptions, natural history, and illustrations.
Within each family, species are listed alphabetically by scientific name. Listings contain the common name, scientific name, nomenclature, form, leaves, flowers, cones or fruits, twigs and buds, bark, wood, natural history, varieties, hybrids, and range, and include line drawings to assist in identification. Technical terms and jargon are used only where accuracy and conciseness would otherwise be compromised. The Introduction and Glossary provide additional information. Foresters, horticulturalists, naturalists, and everyone who loves trees will find North American Trees to be an indispensable reference.
