20 PHARMACAL PLANTS AND THEIR CULTURE. 



CHAPTER II. 



LITERATURE ON DRUG PLANTS AND DRUG PLANT CULTURE. 



In lieu of records and data from California experimental gardens 

 devoted to medicinal plants, we hereby submit the more important 

 citations to the literature treating of the occurrence, distribution, use 

 and cultivation of medicinal plants, especially those found in the State 

 of California. While some citations to the chemical investigations of 

 drug plants are given, no attempt has been made toward completeness 

 in that direction. Such citations would be of inestimable value to 

 investigators and it is hoped that some one may have the time and 

 the opportunity to complete such a task. 



It was thought desirable to include a few citations, which do not 

 refer to medicinal plant culture directly. There is, for example, an 

 extensive literature on fertility of soil, chemistry of soil, seed testing 

 and selecting, plant physiology, tilling of soil, etc., which is of more 

 or less importance to those who desire to enter upon the more intelli- 

 gent consideration of drug-plant culture. In some instances the publi- 

 cations are abstracted very briefly: others are not abstracted, as the 

 title is sufficient to indicate the nature of the subject-matter. After 

 consulting the literature here cited, those interested will no doubt be 

 able to obtain additional literature and to secure, through other sources, 

 additional desirable and necessary information. The Department of 

 Agriculture at Washington, the California State Horticultural Society, 

 the College of Agriculture of the University of California, the various 

 California state, county and local promotion and development com- 

 mittees, and the boards of trade of towns and cities are willing and ready 

 to give information in so far as it is possible. 



Most of the special information, such as range and distribution, 

 morphology, etc., regarding California medicinal plants, will be found 

 in the special California publications, as PACIFIC PHARMACIST, ZOE, 

 ERYTHRAEA, PITTONIA, the PROCEEDINGS OP THE ACADEMY OF SCIENCES, 

 the GEOLOGICAL AND RAILWAY EXPLORATION REPORTS, the ETHNOLOG- 

 ICAL REPORTS AND GOVERNMENT EXPEDITION REPORTS. These may be 

 consulted in the various libraries of the State, as at Sacramento, State 

 University of California, Leland Stanford University, and at the Cali- 

 fornia Academy of Sciences. There are also various California floras, 

 written by well-known botanists, as Jepson, Coulter, Behr, Watson and 

 others, w r hich may be consulted by those interested. It will also be 

 found that the literature on the introduced medicinal plants of Cali-
