it is decapitalized it is at once confused with the adjective mille-

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 arabic 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. Cire. 35: 3. 1901. 
Beyr. in Trin. Mem. Acad. St. Pétersb. VI. Sci. Nat.1: 341. 1834. 
Nees; Doell in Mart. Fl. Bras. 27: 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.
