INTPODUCTORY. 



"^r'HB) first list of the P'lora of Los Angeles County was issued by the 

 I author in October, 1892, and comprised almost all the then known 

 species on the mainland of the County. Since that time the district 

 has been more thoroughly explored, and numerous additions have been 

 made to the list, not a few of which are of species entirely new to science. 

 In view of these additions the Botanical Section of the Southern California 

 Academy of Sciences has deemed it advisable to issue a second list, to 

 include the plants of both the mainland and the Islands of San Clements. 

 and Catalina, which are embraced in the County area. 



In the compilation of this list I desire to express my sincere thanks for 

 the valuable aid rendered by Miss A. J. Merritt, Normal School, Los 

 Angeles; Dr. Hasse, of Santa Monica, and Mr. S, B. Parish, of San Ber- 

 nardino, who have not only placed the accumulated experience of years of 

 investigation at my disposal, but have also revised the manuscript. To 

 the latter gentleman, whose knowledge of the Flora of Southern California 

 is not surpassed by that of any living authority. I am also indebted for the 

 final revision of the proofs. 



From the "Flora of Pasadena," isstied by Mr. A. J. McClatchie, I have 

 taken additional records of locality, and the records of species therein 

 quoted which are not familiar to my colleagues or myself are duly 

 acknowledged. Under these conditions this Catalogue may be considered 

 at least fairly accurate. 



Some of the species have one or two asterisks prefixed. One * indicates 

 those recorded of which we have seen no authentic specimens, some of 

 which we feel assured have been wrongly identified. The original authority 

 is appended. Two ** indicate those recorded in the Botany of California, 

 Brewer & Watson's second edition, which have not, so far as we are aware, 

 been collected in recent years. 



The names printed in italics indicate those species believed to be non- 

 natives of this county. 



Local lists without a collection to indicate exactly the plants referred 

 to are of doubtful scientific value. While we are without a museum or 

 other public institution in which to deposit the collections on which this 

 list is founded, the species indicatedi may be found in the herbaria of the 

 collaborators. 



In the present disturbed state of botanical nomenclature neither the 

 method of arrangement nor the specific names chosen may be considered 

 either modern enough, or ancient enough, to suit the pedagogues. For this
