ieh im Folgenden nieht nur seine neue Synonyma hinzugefügt, sondern dieselben auch in 
4 Füllen (vgl. Eranthis), wo dies nóthig war, mit der Bezeichnung s. l. n. i. (secundum 
leges nomenelaturae internationalis) ergünzt. 
August 1892. Report on the Proceedings of the Botanical Club of the 
American Association for Advancement of science at the Rochester-Meeting: 
(cfr. Botanical Gazette 1892 p. 287—288; more extensively in Bulletin Torrey 
Botanieal Club 1892 p. 290—292). 
Friday, August 19, I. P. M. 
The committee on nomenclature presented its report in printed form, which was 
adopted, article by article, with only a few verbal changes, as follows: 
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 regarded as the funda- 
mental principle of botanical nomenoelature?214). 
2. Beginning of Botanical Nomenclature. — The botanical nomenclature of both genera 
and species is to begin with the publication of the first edition of Linnaeus' Species plan- 
tarum, in 1758 215). 
3. Stability of Specifie 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 216), 
4. Homonyms. — 'The publication of a generic name or a binomial invalidates the 
use of the same name for any subsequently published genus or species respectively217). 
?141) That is in accordance with the Paris Code, but thereby is rejected the 
Berlin resolution IV, the Index inhonestans of Ascherson and consorts. 
?18) That is a concession and presumed emendation to Berlin resolution I; 
formerly American botanists began with 1737 as Britton and others or with 
an earlier date. That proposition was thought an amelioration because the 
illegal edition of Strumpf-Linné's genera plant. of 1752 had been rejected and 
the matter was simplified; but the starting-point of 1737 causes less changes 
in nomenclature than that of 1758. 
?16) That agrees fully with the Paris Code, but it is a rejection of pleonastie 
names, often renewed last time in N.-America, like Hepatica Hepatica Karsten, 
not allowed in $ 60? of Paris Code, and that is again a rejection of the so- 
ealled Kew rule. 
(4) That is the new rule called *Once a synonym always a synonym", but it 
is against $ 4 the of Paris Code, which requires that established custom becomes 
law if any rule is questionable. That new rule has never been established custom in 
botany; but there is a sound basis in that new rule. If ever accepted by a 
future international and competent congress it can never get retroactive force 
and invalidate numerous old well known and everywhere used names and 
such ones as are valid according to the present Code. "The new rule can 
only be accepted for future new or renewed names, and act from the date of 
publieation of the new rule by a competent congress. Even then would it 
be of an important and incisive effect, but also of a very calming effect for 
a greater stability in nomenclature; for then it can no longer be allowed to 
change the last accepted or renewed names by digging out or changing older 
double homonyms. Of course a name anywhere used for the first time since 
the starting-point of our nomenclature can get valid; but later homonyms are
