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 18, 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: 
I. The Law of Priority.—Priority of publication is to be re- 
garded as the fundamental principle of botanical nomenclature. 
Il. Beginning of Botanical Nomenclature.—The botanical no- 
menclature of both genera and species is to begin with the publication 
of the first edition of Linnzeus’ Species Plantarum in 1753. 
I. Stability of Specific Names.—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. Homonyms.—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 * 
(1) 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 * 
(1) 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 Names.—Similar generic names are not to 
be rejected on account of slight differences, except in the spelling 
of the same word; for example, Afios and Apium are to be re- 
ef Amended Aug. 22, by inserting the word ‘ only.”
