j v • HISTORICAL NOTE. 



nomenclature have, doubtless, made him most widely known, since 

 in America no other writer has so pronounced and extreme views 

 upon this subject. Nearly all of his many writings, whatever the 

 title or topic' are colored by the ideas of nomenclature which have 

 brought him into prominence. The particular contributions which 

 are most available to the Californian student are the Flora Francis- 

 cana still incomplete, and the Manual of Botany of the Region of 

 San Francisco Bay, in both of which his principles of nomenclature 

 are exemplified. He has what is termed a keen eye for specific differ- 

 ences, has published a very large number of new species, and is the 

 author of larger number of new names arid new combinations than 

 any other American botanist or zoologist. He has also an apprecia- 

 tion of natural relationships which has led him to propose new 

 arrangements for many genera and species. It should be added that 

 many of these changes have found wide acceptance. 



During this long period there have been many other resident 

 workers on the flora of western middle California. Of these mention 

 should be made of Dr. Albert Kellogg, one of the founders of the 

 California Academv of Sciences; Dr. Hermann H. Behr, author of a 

 Flora of the Vicinity of San Francisco; Mrs. Katherine Brandegee, 

 formerly Mrs. Curran, who has studied very thoroughly the local 

 flora for many years and published revisions of genera and of species; 

 Mr. Volney Rattan, Miss Alice Eastwood, and many others whose 

 names find mention in the following pages.
