Peterson Field Guide to Eastern Trees
George A. Petrides and Janet Wehr
The early one-third of this book organizes trees into small groups with a common set of features, displayed in a chart of key characters on the left opposite well-done botanical illustrations on the right. This technique that allows the user to quickly determine a specimen's possible identity, which can be confirmed or investigated further in the species descriptions, drawings, photographs, and range maps that follow.
Newly designed, this field guide features detailed descriptions of 455 species of trees native to eastern North America.
