Jepson went into the field for seven weeks with a collecting and 

 camping outfit, after the fashion long in vogue on the Pacific Coast. 

 The route followed is here given: From Berkeley to San Jose and 

 the upper Santa Clara Valley southward and eastward to Pacheco 

 Pass, then directly westward across the Coast Range to the ocean at 

 Soquel and Santa Cruz, then northward and eastward traversing the 

 Coast Range region once more from the Santa Cruz Mountains to 

 the Livermore Pass, by way of Mission San Jose; at the Liverraore 

 Pass passing into and across the San Joaquin Valley to Oakdale 

 and southward to La Grange on the Tuolumne River, at that point 

 entering the Sierra foothills. From Coulterville the Hazel Green 

 route into the Yosemite region of the High Sierras was followed. A 

 very large and important collection of algse and flowering plants 

 was made, the Coast Range collection of the latter proving very 

 rich in rare species and forms of morphological interest. The 

 exaujination of the alkaline flats near Hollister developed various 

 facts bearing on the relation of the vegetation of that region to the 

 dry season flora of the Sacramento Valley. A short time was 

 devoted to the Lower San Joaquin on the return trip to Stockton. 



From April 24 to May 31 Mr. J. Burtt Davy, under the direc- 

 tion of the Department of Agriculture of the University, devoted 

 himself to field studies of the alkaline vegetation of the Upper 

 San Joaquin Valley. During this time he collected 1,029 numbers 

 from the plains and bluffs skirting the foothills near Bakersfield, 

 the alkali patches bordering the Kern Delta, and Tulare Lake near 

 Delano, the Kern Delta, the sandy plains at foot of the Tejon and 

 Tehachapai Ranges, San Emigdio Canon, Tehachapai Valley, Dry 

 Lake, Antelope Valley, and the Tejon Pass. On a second trip from 

 October 12 to 27 Dry Lake, Antelope Valley, and Bakersfield 

 were revisited. In the middle of March Mr. Davy made a small but 

 interesting collection of plants at Duncan's Mills, Cazadero, and 

 Fort Ross, visiting the old historic ground whence the seeds of some 

 of Fischer & Meyer's plants came. 



Miss Alice Eastwood, curator of the Herbarium of the Cali- 

 fornia Academy of Sciences, accompanied Mrs. Ida Blochman on a 

 trip along the Cuyaman or Santa Maria River, which forms the 

 boundary between San Luis Obispo and Santa Barbara Counties, and
