7. Depariment of Botany. — The usual activity has been 

 displayed by the curator in caring for the herbarium and se- 

 curing accessions to it. During the year there have been added 

 to the herbarium 2220 mounted sheets representing 1241 spe- 

 cies new to the collection. The herbarnim now contains a total 

 of 20,586 mounted sheets representing 7997 species, all prop- 

 erly arranged in the herbarium cases. Besides these there is a 

 large number of specimens not yet mounted. There are also 

 475 fungi types in envelopes arranged alphabetically in boxes. 

 These were saved from the fire of 1906. Besides these there 

 are 1136 specimens of phanerogams containing 711 types and 

 96 cotypes saved from the fire. Besides these, certain other 

 specimens were saved from the fire because of the fortunate 

 circumstance that they were loaned at the time. They are as 

 follows : A large bundle of Giiias returned from Germany, 

 and containing many types ; a bundle of Ptelea returned from 

 Washington ; some specimens of EscJischoltzia which had been 

 loaned to the late Dr. Edward L. Greene; and most of the 

 Academy's specimens of Lupimis and some of Delphinium 

 which had been loaned to the Gray Herbarium, all of which 

 have been returned. All these specimens saved from the fire 

 fill one herbarium case in which they are now installed. 



Owing to the inexcusable failure of the author of the re- 

 ports on the Galapagos plant collections to correlate properly 

 his published identifications with the specimens, the curator 

 has found it necessary to go over the entire collection and iden- 

 tify each specimen anew. This has entailed a vast amount of 

 work. 



Within the year the curator made a number of brief collect- 

 ing trips, as follows : One to the region of the San Antonio 

 and Nacimiento rivers near Jolon in Monterey County, and to 

 Aromas in San Benito County; one to Mt. Diablo; 

 one to Mt. St. Helena, Calistoga, and the Petrified 

 Forest; one of a week's duration in the foothills of 

 Mariposa County; one to Bodega Point, the type lo- 

 cality of many species; and finally, a brief trip to Los 

 Angeles and San Diego, All these trips were brief and were
