DEAR SIR: 



I propose to issue, for circulation among the work - 

 ing Botanists of this State, a little monthly sheet {about 

 the size of the Torrey Botanical Bulletin) devoted to the 

 publication of a Catalogue of the 



I shall aim to include all species and marked vari - 

 eties known to occur within our limits— to give localities 

 and collectors' names for those which are not common— 

 and indicate the area of distribution of such species as 

 do not occur throughout the State. Three pages will be 

 devoted to the List and one to miscellaneous notes. 



I beg your co-operation in this matter. 



Inclosed, you will receive the first sheets of a list print- 

 ed for the purpose of collecting information on the sub- 

 ject. It is made up from Mr. I. A. Lapham's List—pu' 

 lished in 2d Vol. Trans. III. Ag'l Soc'y, 1856-7— the a 

 ditional list in 4th Vol. by Dr. Vasey and others, and, sei 

 eral local catalogues. 



Please mark (by a — .at the left of the name) every 

 species and variety which you know grows in the State 

 —especially those which I have omitted — give all stations 

 of rare plants known to you— note any peculiarity of the 

 species not mentioned in our popular Manuals, and as 

 far as possible indicate the Northern limit of species 

 having a Southern range and vice versa. 



s^I hope also that you will contribute to our page 

 of miscellaneous notes. 



Tours very respectfully, 



HARRY N. PATTERSON.
