BOTANICAL CLUB of the American Association for the 

 Advancement of Science. Code of botanical nomen- 

 clature. (Bulletin of the Torrey Botanical Club. XXXI. May, 

 1904. p. 249—261.) 



A code of nomenclature prepared and recommended by a 

 committee of twenty-three American botanists, who announce 

 their purpose to move, in the Vienna Congress of 1905, that, 

 in accordance with the provisions of the committee on Organi- 

 zation of the Congress, the Paris code of laws of 1867 be 

 amended by the abandonment of all its articles and the Sub- 

 stitution of the code now recommended, which is printed in 

 English(p. 251— 261), French (p. 265—276) and German (p. 279 

 —290). 



The code is divided into Part I. Principles, Part II. Canons, 

 and Part III. Orthography and Citation. Nineteen canons are 

 included in Part II, grouped under 1. categories of Classi- 

 fication, 2. formation of names, 3. publication of names, 4. ap- 

 plication of names, and 5. rejection of names. 



The füll English text of the code iollows: 



Part I. Principles. 



1. The primary object of formal nomenclature in syste- 

 matic biology is to secure stability, uniformity and 

 convenience in the designation of plants and animals. 



2. Botanical nomenclature is treated as beginning with the 

 general application of binomial names of plants (Lin- 

 naeus' Species Plantarum, 1753).
