 Eschscholtzia Californica, H. H. Rusby. (Reprint from Drug. 

 Bull. June, 1889, PP- 8, with colored plate). 

 This species is of special importance to the druggistfrom the fact 

 that morphine is said to have been recently detected in it. The 

 author calls attention to the necessity of determining whether 

 this is a characteristic of the typical species only, or of the 

 many other closely allied species and varieties, which have 

 been the source of so much discussion, and which have caused 

 so many rearrangements of the genus.
