proportion of the characteristic famiHes of the Rocky 

 Mountain area : and, with one or two exceptions, I have 

 been able, with the aid of my own Herbarium, which is rich 

 in representatives of the North American Flora, to name 

 with certainty the specimens collected. Very nearly all of 

 them have a wide range throughout the State of Colorado, 

 extending to the north into Montana, and southwards to 

 New Mexico and Arizona. A few are also inhabitants of 

 the Eastern States ; and no less than five also occur in 

 Great Britain. These are Calystegia sepium, Huniulus 

 Lupnlus, Galium boreale, Achillea Millefolium, and Equise- 

 tuvi arvense. 



No specimens of Graniina or Filices are represented.
