CITATION OF SPECIMENS. 



In the present paper no attempt has been made to cite all of 

 the specimens examined. If the species under consideration is 

 well known and its distribution clearly given in some standard 

 work, no specimens are cited. When it is rare, when there may 

 be some doubt as to the form described, or when for any reason 

 it may be desirable to know exact stations, all of the specimens 

 at hand are listed. Sometimes a few examples, to fix the identity 

 or to express extreme range, are given and the remainder left 

 without citation. In no case (except possibly by error) has a 

 specimen from Southern California been cited unless it has passed 

 under my personal observation, or a Southern California locality 

 cited unless verified by myself, save in those instances where some 

 other authority, preceded by the expression "ace. to" (according 

 to), is mentioned. The botanists to whom reference is most 

 frequently made in this way and their publications from which 

 the data were gathered are the following :

 mostly in the Proceedings of the American Academy of Sciences.

 American Academy of Sciences.
