Excerpt from A Field Key to the Genera of the Wild and Cultivated Hardy Trees of the Northeastern United States and CanadaThe range of the trees included runs from northern Canada to a line about as far south as central Virginia, and west to the Mississippi River. Many of the trees will extend farther south and west. Some genera will grow over most of the range, while others are restricted to a much smaller territory. Only those hardy in at least the southern part of the area have been listed.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
