270 • Mnhlenbergia, Volume 2 



On May loth a trip wis made to Smith creek, elevation 2100 

 feet, at the foot of Mt. Hamilton, and again on May 30th, at 

 which time Mt. Hamilton was ascended. Interesting collections 

 were made at this place, one object being to note the similarity 

 or dissimilarity between the plants of the middle and outer 

 •Coast Ranges. This point will be dwelt upon later. 



Four trips were made into San Mateo county immediately 

 north of Santa Clara county, two of them to the extreme north- 

 ern end of the county to the San Bruno hills just outside of San 

 Francisco, and to the low sandy hills near by about Lake Mer- 

 ced. Two trips were made to points near San Mateo on the 

 Half Moon Bay road. This latter territory is one of the best 

 botanical grounds in the peninsula, as it abounds in moist places 

 and numerous springs and lakes, chief among which are the 

 Crystal Springs lakes. Several local species have been collected 

 here, and when once the place is thoroughly explored others 

 will no doubt be found. A number of species apparently have 

 their southern limit here. 



Pacific Grove, Monterey county, was visited on May ist in 

 company with Professor P. B. Kennedy, of the University of 

 Nevada, the chief object being a study of the several clovers 

 peculiar to that place, but several species of other genera not 

 collected there in 1903 were obtained. 



Full citations are omitted in the case of species hitherto 

 reported upon in these pages during the past two years. 



My thanks are due to the members of the department of 

 botany of the University of California for courtesies extended 

 while determining and verifying the plants in this collection. 



The nomenclature of this paper is that of the "American 

 - code," the official pronouncement of the majority of American 

 botanists, voiced through the Botanical Club of the American 

 Association for the Advancement of Science. To any one fa- 

 miliar with the shortcomings of the so-called international con- 

 gress at Vienna, adherence to a better set of rules needs no apol- 

 ogy.
