Almost all technical botanical terms have been translated into ordinary English, as this book is intended primarily for the general public, but as a large number of the plants given have never before been illustrated, or even described, except in somewhat inaccessible or technical publications, it is hoped that the scientist also may find the contents both interesting and useful.
The nomenclature used, with few exceptions, is that of the American Code. Where these names differ greatly from those in common usage the latter are given as synonyms in brackets, making the book more useful to all readers. The botanical names are marked with an accent. Two accents are used, the grave (`) to indicate the long English sound of the vowel, such as the "i" in "violet," and the acute (´) to show the short sound, such as the "i" in "lily."
Professor J. J. Thornber, of the University of Arizona, is responsible for the botanical accuracy of the text and his knowledge and patient skill have made the book possible.
Thanks are due for most valuable assistance in the determination of a very large number of specimens to Miss Alice Eastwood, of the California Academy of Sciences. Also to Dr. W. L. Jepson of the University of California; Professor A. O. Garrett, of Salt Lake City; Professor A. R. Sweetser, of the University of Oregon; Mr. S. B. Parish, of San Bernardino, Cal.; Mrs. Henshaw, of Vancouver, B. C.; Dr. A. Davidson, of Los Angeles; and Mr. Marcus E. Jones, of Salt Lake City. Also for advice and assistance to Dr. N. L. Britton, and Dr. H. M. Richards of New York; to Dr. Livingston Farrand, of Colorado; Mr. C. R. Orcutt, of San Diego; Mr. Carl Purdy, of Ukiah, Cal.; Professor Flett, of Mt. Rainier National Park; Miss Winona Bailey, of Seattle; Professor J. H. Paul, of Salt Lake City; and many other kind friends.
The arrangement is that originated by Mr. Schuyler Mathews, in his Field Book of American Wild Flowers, which has been found very popular in the East, but, in this book, most of the genera, as well as the species, have been very briefly described.
