Excerpt from New Manual of Botany of the Central Rocky Mountains: Vascular Plants IN 1885 the Manual of the Botany of the Rocky Mountain Region was published. It was based upon general explorations of the region concerned, and was confessedly tentative. During the last twenty-four years, general explorations of the vascular flora have merged into more or less intensive studies, and the manual long ago became inadequate. It was the original purpose to revise it as frequently as new material justified, but the author's time and attention became absorbed in other kinds of botanical work, so that no revision has appeared. As the book continued to be in demand, it seemed necessary, in justice to its users, to bring it up to date. This work has been undertaken by Professor Aven Nelson of the University of Wyoming (laramie), whose great familiarity with the flora of the Rocky Mountain region suggested his fitness for the task.
