NOMENCLATURE OF PLANTS. 



BY KATHARINE BRANDEGEE. 



The botanical Club of the American Association for the advance- 

 ment of Science, which met this year on August i8, at Rochester, 

 N. Y., appointed, on motion of N. L. Britton, a committee to con- 

 sider the question of nomenclature and submit a set of recommend- 

 ations to the club. The committee as appointed consisted of N. L. 

 Britton, John M. Coulter, H. H. Rusby, W. A. Kellerman, F. V. 

 Coville, L. M. Underwood and L. F. Ward, and on the following- 

 day submitted this report: 



Resolved, That the Paris Code of 1867 be adopted, except where 

 it conflicts with the following recommendations: 



L The Law of Priority. — Priority of publication is to be re- 

 garded as the fundamental principle of botanical nomenclature. 



IL Begi7ining of Botanical Noiueiiclaticre. — The botanical no- 

 menclature of both genera and species is to begin with the publication 

 of the first edition of Linnaeus' Species Pla7itariivi in 1753. 



in. Stability of Specific Navies. — In the transfer of a species to 

 a genus other than the one under which it was first published, the 

 original specific name is to be retained, unless it is identical with the 

 generic name or with a specific name previously used in that genus. 



IV. Ho7nonyms. — The publication of a generic name or a bi- 

 nomial invalidates the use of the same name for any subsequently 

 published genus or species respectively. 



V. Publication of Genera. — Publication of a genus consists* 

 (i) in the distribution of a printed description of the genus named; 

 (2) in the publication of the name of the genus and the citation of 

 one or more previously published species as examples or types of 

 the genus, with or without a diagnosis. 



VI. Publication of Species. — Publication of a species consists* 

 (i) in the distribution of a printed description of the species named; 

 (2) in the publishing of a binomial, with reference to a previously 

 published species as a type. 



VII. Similar Generic Nariies. — Similar generic names are not to 

 be rejected on account of slight differences, except in the spelling 

 of the same word ; for example, Apios and Apinin are to be re- 



* Amended Aug. 22, by inserting the word " only."
