PREFACE. 



This is the only fully illustrated book of western flowers, 

 except Miss Parsons's charming book, which is for Califor- 

 nia only. The drawings have all been made from life. 

 Allowance must be made for differences in appearance, 

 owing to locality, and the text should be consulted for the 

 size, as, on so small a page, some of the plants must be 

 drawn smaller than others. 



Almost all technical botanical terms have been trans- 

 lated 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.

 Mathews, in his Field Book of American Wild Flowers,
