Trees of the Northern United States / Their Study, Description and Determination

This instructional manual guides teachers and private students through practical study and identification of trees found in the region east of the Rocky Mountains and north of the southern boundaries of Virginia and Missouri. It emphasizes year-round, observable characters—leaves, bark, wood, and fruit—rather than fleeting flowers; explains roots, stems, leaves, flowers, fruit, winter study, and specimen preparation; supplies illustrative figures, pronunciation-marked scientific names, keys for beginners, and a glossary; and includes species descriptions covering native and cultivated trees and some shrubby plants that may assume tree forms.
