List of Plants collected by Emanuel Samuels, in 

 Sonoma County, California, in 1856. By Asa Gray, 

 M. D. 



The plants named below were gathered by Mr. Samuels dur- 

 ing a year's residence in California, and form part of the collec- 

 tions made under the auspices of the Boston Society of Natural 

 History and the Smithsonian Institution at Washington. Mr. 

 Samuels made collections in all the departments of Zoology and 

 Botany, and the frequent rarities in his small but interesting 

 collection bear testimony to his close observation and assiduity.
