PREFACE Vll 



sidered. The Herbarium, Library, and Botanic Gardens of the 

 University of California have been freely consulted in the prep- 

 aration of the Flora and all collections made by the authors are 

 now preserved at this Institution. 



The text figures in this Flora are original and were prepared 

 by Miss Anna Hamilton, Miss Helen M. Gilkey, and Mrs. Car- 

 lotta C. Hall. The frontispiece and the illustrations facing pages 

 56 and 58 are from photographs by Mr. O. V. Lange, the plates 

 facing pages 96, 178, and 250 are from photographs by Professor 

 J. N. Le Conte, those facing pages 4 and 124 are from photo- 

 graphs by the Pillsbury Picture Company, that facing page 190 

 is from a photograph by Mr. Frank Adams, while those facing 

 pages 46 and 162 are from the collection of the Southern Pacific 

 Company and are used through the courtesy of Mr. James 

 Horsburgh, Jr. 



Note Concerning Names and Accents. — No new botanical 

 names or combinations are published for the first time in this 

 Flora. Such as are ascribed to the authors have been previously 

 published, either in the "Botanical Gazette," vol. 31, or in the 

 "University of California Publications in Botany," vols. 1, 3, and 

 4. A name appearing in italics at the end of a botanical descrip- 

 tion is to be considered a synonym. Botanical names are usually 

 pronounced according to the pronunciation of Latin after the 

 English method, although exceptions are necessarily frequent. As 

 a general guide, the names in this Flora are marked with accents. 

 Two accents are used, the grave C) to indicate the long English 

 sound of the vowel, the acute (') to show the shortened or other- 

 zvise modified sound.
