Fripay, AuGust 18, 
In the absence of the President, Prof. W. P. Wilson, the meet- 
‘ing was opened by the Vice-President, Prof. W. A. Kellerman. 
In. the absence of the Secretary, Prof. W. A. McBride, his 
office was filled by the election of Mr. W. T. Swingle., 
_ The report of the Committee on Nomenclature, appointed at 
the Rochester meeting of 1892 to prepare a check-list of the 
flowering and fern plants of Northeastern North America, was 
made by Prof. N. L. Britton, Chairman. The list was presented 
nearly complete for printing. Discussion of the report occupied 
the remainder of the day’s session. The report was received, 
and the following recommendations of the committee were 
adopted: ; 
1. The amendment of Section III. of the Rochester Code of 
Nomenclature by striking out all after the word “ retained.” 
This recommendation is based on the mature judgment of the 
committee, after watching for a year the progress of the demand 
for a rule which shall admit no exceptions whatever and effect 
the closest approximation to the immutability of the specific name. 
This action authorizes the use of specific names identical with 
the generic, such as Catalpa Catalpa, and preserves the immuta- 
bility of the specific name, in whatever genus it is first published, 
even if the same binomial has been published between the time of 
the first publication of the species and its transfer to the accepted 
genus, as for example : 
rahi treks PINNATUM (Walt.) Greene, Bull. Cal. Acad. ii. 39 
I ; | 
Eytan pinnatum, Walt. Fl. Car. 174 (1788). ic oe 
Sisymbrium canescens, Nutt., Gen. ii. 68 (1818); not Sayv- 
brium pinnatum, Barn. in Gay. Fl. Chil. i. 125 (1845); 
which is to receive another name. : 
2. That the general sequence of natural orders as taken up 17 
Engler and Prantl’s “ Natiirliche Pflanzenfamilien ” be adopted. 
The check-list will therefore begin with the Pteridophyta, fol- 
lowed consecutively by the Gymnosperme, Monocctylodone and 
Dicotylodonz. . |
