DESCKIPTION OF THE PLANTS COLLECTED DURING THE EXPE- 

 DITION: BY DE. JOHN TOEEEY. 



No. 96, St. Mark's Place, New York, 



August 10, 1853. 

 Dear Sir : I have examined the collection of plants that yon brought 

 from the headwaters of the Red river, towards the Rocky mountains. 

 The flora of this region greatly resembles that of the upper portion of 

 the Canadian. It is remarkable that there occur among your plants 

 several species that were first discovered by Dr. James, in Long's Ex- 

 pedition, and have not been found since until now. Your collection is 

 an interesting addition to the geography of North American plants, and 

 serves to mark more clearly the range of many western species. For 

 particular remarks on the rarer plants, and descriptions of the new 

 species, I refer you to the accompanying list. 



At your request I have had some of the rarer plants drawn and en- 

 graved, to illustrate your report to Congress. 



I am, dear sir, 



Yours truly, 



JOHN TORREY. 

 Captain R. B. Marct.
