The committee thus established prepared the Hst and pre- 

 sented it at the next meeting of the Botanical Club of the Amer- 

 ican Association, held at Madison, Wisconsin, August, 1893, at 

 the same time submitting the following recommendations, which 

 were adopted :"" 



1. The amendment of Section III. of the Rochester Code of 

 Nomenclature by striking out all after the word "retained." 



2. That the general sequence of natural orders as taken up in 

 Engler and Prantl's " Natijrliche Pflanzenfamilien " be adopted. 



3. That in determining the name of a genus or species to 

 which two or more names have been given by an author in the 

 same volume or on the same page of a volume, precedence shall 

 decide. 



The committee was authorized to proceed with the publication 

 of the list, matters concerning it not determined by the Club were 

 referred to the committee with power, and it was increased to nine 

 members by the appointment of Professors Edward L. Greene 

 and William Trelease. 



The committee at once began the consideration of the topics 

 necessary to the completion of the list on which no instructions 

 had been given by the Club. After much preliminary corre- 

 spondence it was decided by vote in each instance : 



I. That the original name is to be maintained whether pub- 

 lished as species, subspecies or variety. 



II. That varieties are to be written as trinomials. 



III. That specific or varietal names derived from persons or 

 places, or used as the genitive of generic names or substantives 

 are to be printed with a capital initial letter. 



IV. That no comma is to be inserted between the specific or 

 varietal name and the name of the author cited. 



The committee called to its assistance specialists in various 

 groups of plants, and their contributions are credited in the foot- 

 notes to the list ; it has also consulted many other botanists on 

 questions in which doubt arose as to the occurrence of certain 

 species within the geographical area adopted and on other topics. 

 The citations of place of publication and date have been verified 

 as far as the resources of American botanical libraries have
