 species of herbaceous plants extend over the same range. 



The natural order and nomenclature, as given in Gray's New Manual 

 of Botany, Illustrated, have generally been followed unless otherwise 

 stated. 



The writer is much indebted to Prof. A. S. Hitchcock and Agnes Chase 

 of the United States Department of Agriculture for an examination and 

 determination of the grasses, and to K. K. Mackenzie of New York City 

 for an examination of all species of Cyperaceae and many other plants. 

 In the genus Carec:, Mr. Mackenzie's determinations and names have 

 been strictly followed. 



Tf any of these names at present are not found in the two manuals 

 now commonly used, they will soon appear in the forthcoming North 

 American Flora. When the scientific names of Gray's "New Manual 

 of Botany " differ from those in Brit ton and Brown's " Illustrated Flora, " 

 Second Edition, the latter are given in parentheses, except in the genus 

 Car ex.
