BIBLIOGRAPHY 



280. It is frequently necessary, or at least desirable, 

 to refer to works, serials and periodicals. For convenience, 

 the titles are usually abbreviated, and the citation of 

 volume and page follows a definite form. If titles are 

 abbreviated it is the aim to make abbreviations under- 

 standable, concise and consistent. The important words 

 of the title are selected and are abbreviated as are the 

 names of authors, that is, to the vowel of the second syl- 

 lable. In referring to an article in a periodical, the volume 

 and page of the original are given rather than a reference 

 to a separate of the article. Many botanists have adopted 

 the convenient system of citing the volume of a periodical 

 or work in arable in bold-faced type. Following the vol- 

 ume number is a colon and the page and finally the year. 



The examples given below will illustrate the system : 



Vasey, Bot. Gaz. 9: 97. 1884. 



H. B. K., Nov. Gen. & Sp. 1 : 99. 1816. 



Swartz, Prod. Veg. Ind. Occ. 23. 1788. 



Scribn. & Merr. U. S. Dept. Agr. Div. Agrost. Circ. 35: 3. 1901. 



Beyr. in Trin. Mem. Acad. St. Petersb. VI. Sci. Nat. 1 : 341. 1834. 



Nees; Doell in Mart. Fl. Bras. 2^: 213. 1877. 



If a botanist describes a species in the work of another, 

 the name of the former is followed by "in," as in the last 

 two examples. A semicolon following an author's name 

 indicates that the author proposed the name but the 

 description was written by the botanist whose name fol- 

 lows the semicolon.
