Some Recent University of California Publications=)= 



The first ten numbers of volume 4 of the "University of Cali- 

 fornia Publications in Botany" represent a considerable variety 

 as to subject matter, with, however, a decided preponderance, 

 so far as the titles are concerned, of papers relating to the marine 

 algae of the Pacific Coast. 



Dr. H. M. Hall's "Studies in ornamental trees and shrubs" 

 includes descriptions and illustrations of some of the more com- 

 mon and desirable of the cultivated ornamental trees and shrubs 

 of California. There is probably no state in the Union in which 

 cultivated, largely exotic, trees and shrubs are relatively so 

 conspicuous to the casual visitor, at least, as in California, and 

 any paper that assists in their identification will be welcomed by 

 many. The species treated are largely of Australian and New 

 Zealand origin and many are of the genera Pittosporum, Hakea, 

 Callistemon, and Melaleuca. The species of Eucalyptus, of which 

 about 100 are said to be cultivated in California, are omitted, 

 whether because they are not considered sufficiently ornamental 

 or because they are held to be adequately treated elsewhere
