Abstract

The Vegetation of the Rocky Mountain Region

The article focuses on the book "The Vegetation of the Rocky Mountain Region," by A. Gray and J.D. Hooker. This sketch of the botany of the great interior region of the United States is the result of the journey which the distinguished authors made to the Pacific Coast during the summer of 1877 as associates of the Government survey of that year. The region considered, and compared botanically, with the regions east and west of it, extends from the eastern edge of the great plains which form the elevated plateau from which the Rocky Mountains spring, to the eastern base of the Sierra Nevada, and from the British south to the Mexican boundary although that portion of the country lying between the thirty-sixth and forty-third degrees of north latitude, with which, from personal observation, the authors are most familiar, is most fully treated.
