DEPARTMENTAL REPORTS 



Department of Botany 

 By Alice Eastwood, Curator 



The herbarium of the California Academy of Sciences now numbers 

 59,589 specimens, mounted, classified and systematically arranged. Approx- 

 imately 17,000 species are represented. 



Accessions have been received from various sources : Forty-eight dif- 

 ferent individuals have sent specimens, most of them for identification. 

 The largest accession was the herbarium of the late Dr. E. K. Abbott, of 

 Salinas, which was presented to the Academy in 1918, but not incorporated 

 in its herbarium until 1919. In addition to a fairly complete collection 

 from the vicinity of Monterey and Salinas, it included collections from 

 Michigan and Illinois, and a most interesting lot of European specimens 

 collected many years ago in the region of northern France devastated by 

 the late war. 



Exchanges have been received from the U. S. National Museum, from 

 Ira W. Clokey, of Denver, Colorado, and the Rev. John Davis, of Hannibal, 

 Missouri. 



Duplicates have been sent to the following from which we shall obtain 

 specimens in return when they distribute duplicates : 



The Arnold Arboretum 786 



Gray Herbarium 1454 



Missouri Botanical Garden 489 



New York Botanical Garden 940

The middle of March the curator started on a collecting trip in Arizona 

 and New Mexico. This was financed by the Arnold Arboretum of Har- 

 vard University, and at the request of Professor C. S. Sargent, Director 

 of the Arnold Arboretum and Professor of Forestry, who wished to have 

 a systematic collection made of the cottonwoods of the places visited, 

 particularly, the country around Silver City, New Mexico. Collections 

 were accordingly made at the following places : Indio and Needles, Cali- 

 fornia; Yuma, Casa Grande, Sacaton, Tucson, Bowie, Globe, Roosevelt 

 Dam and Fish Creek (on the Apache Trail), Ash Fork, Prescott, and 

 Topock, Arizona; and Silver City, Fort Bayard, Santa Rita, Whitewater 

 Junction, Tyrone, and Lordsburg, New Mexico. Ten days were spent at 

 Tucson, and five weeks at Silver City. 



At most other places only a day, or perhaps a few hours between 

 trains, was spent. Several days were devoted to Los Angeles, chiefly at a 

 camp in San Gabriel Canyon. About the middle of June a trip was made 

 to the Cleveland Forest Reserve, San Diego County, in search of a rare 

 Celtis for Professor Sargent, at which place a large collection was made. 

 Altogether there were added to the herbarium, 1,723 specimens, but several
