138 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 



Johnston also collected 130 specimens and many duplicates on St. George 

 Island at Dr. Hanna's suggestion. Mr. Eric Walther, who has been inde- 

 fatigable in seeking for the different species cultivated in Golden Gate 

 Park so as to label them under my supervision, has added about 450 speci- 

 mens, chiefly exotics, many of them new to the collection. 



The curator spent a short time in April along the southern boundary 

 of the state and collected 285 species and duplicates. During the visit in 

 June to attend the meeting of the Pacific Division of the American Asso- 

 ciation for the Advancement of Science at Seattle, a small collection of 

 about ninety species was made around Seattle, and on a short trip to 

 Victoria and Nanaimo, British Columbia, 247 species and duplicates were 

 collected. Exceptional opportunities for collecting were given by the mem- 

 bers of the British Columbia Biological Station, who offered both hospi- 

 tality and guidance. Several small collections were made in Solano, 

 Marin and San Francisco counties, chiefly in type localities. 



Much time has been spent in naming the trees and shrubs in Golden Gate 

 Park so as to correctly label them. In order to facilitate this work, books 

 not in the Academy library are greatly needed as the plants in the park 

 come from all parts of the world. About 600 species have been named 

 and labels attached to 2000 plants. Some of the genera, such as Acacia, 

 Eucalyptus, Veronica, Escallonia, and the bamboos have been very diffi- 

 cult. Duplicate specimens are being collected and prepared to send to the 

 best authorities for verification of the identifications. 



The care of the growing herbarium takes much time, and a great deal 

 of the detail work falls on the curator. This prevents the accomplishment 

 of original work which should be done. 



The flower show in the vestibule fills a great want in the community. 

 During the year hundreds of species of exotic and native plants are ex- 

 hibited labelled with scientific and common name and native home. With- 

 out the care and attention of Mrs. Johanna E. Wilkens it would be im- 

 possible to keep this clean and attractive. 



The California Botanical Club has about 60 members and holds meetings 

 once a week either at the Academy or on an excursion to some place near 

 the city. Its members help the herbarium in many ways, particularly 

 Mrs. Marian L. Campbell and Mrs. E. C. Sutlift'e, who bring in specimens 

 continually for the herbarium and the flower show. Mrs. Enid Reeves 

 Michaels, one of the members now residing in the Yosemite Valley, has 

 been keeping up a flower show in the valley throughout the season, at 

 her own expense and by her own efforts. Recently, the Club has pur- 

 chased for the Museum 360 pictures of California wild flowers photo- 

 graphed and colored with great skill and accuracy by Antone J. Soares. 

 These will be installed soon so as to be on exhibition in the Museum. 



Duplicates distributed. — 230 to the Agricultural College, Buenos Aires, 

 in exchange ; 360 to the Royal Herbarium, Kew, for exchange ; 205 to the 

 Herbarium of the British Museum, for exchange ; 300 to the Arnold 

 Arboretum, for exchange. 



All our Senecios have been sent to Dr. J. M. Greenman at the Missouri 

 Botanical Garden, who is monographing the genus, and our undetermined
