ing-plants-as-one-pleases ”—and their publications are in consequence 
marred by the illegal nomenclature. Manuals and handy reference 
floras, most local lists and many monographs have perpetuated the 
faulty and insular methods and it is but very recently that a concerted 
attempt is being made to establish this department of botanical work 
upon the only sure foundation possible without a complete withdrawal 
from the existant system.—Conway MACMILLAN. 
Rules of Botanical Nomenclature.—It is with great pleasure 
that we print the following rules of botanical nomenclature, as adopte 
by the Botanical Club of the American Association for the Advance- 
of Science, at a meeting held in Rochester, August 19th, 1892. We 
trust that they will be generally accepted by American botanists. 
Resolved: That the Paris code of 1867 be adopted, except where it 
conflicts with the following: 
I. Tar Law or PRIORITY. 
Priority of publication is to be regarded as the fundamental princi- 
ple of botanical nomenclature. 
II. BEGINNING or BOTANICAL NOMENCLATURE. 
The botanical nomenclature of both genera and species is to begin 
with the publication of the first edition of Linnzus “Species Plant- 
arum,” in 1753. 
III. STABILITY or 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. HOoMONYMS. 
The publication of a generic name or a binomial, invalidates the 
use of the same name for any subsequently published genus or species 
respectively. 
V. PUBLICATION OF GENERA. 
Publication of a genus consists only (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 pub- 
lished species as examples or types of the genus, with or without a 
diagnosis.
