 AssiNiBOiA, Assiuiboiue River (J. Macoun) : Alberta, Bow River 

 (J. Macoun) : Colorado, Rocky Mts., alt. 2460 m. {E. L. Greene in 

 Exsicc. Oluey) ; Twin Lakes {J. Wolfe, no. 1060 [type]) ; Clear Creek 

 (Parry, no. 386, Patterson, no. 144, in part) : Utah, Aquarius Plateau 

 (L. F. Ward, no. 484) : Idaho, Lake Pend d'Oreille {/Sandberg, Mac- 

 Dougal S^ Heller, no. 751). A plant confined in the East to arbor- 

 vitae swamps at low altitudes, and in its tall lax habit and very distant 

 spikelets hardly suggesting the dwarf alpine G. capillaris with approxi- 

 mate spikelets. Somewhat similar specimens in the Gray Herbarium 

 from Salzburg, Austria, suggest that the same form may be present in 

 Europe.
