 Jjfixiflorum is a characteristic species of the coast region of 

 Alaska, reaching northward into the Yukon Valley and south 

 ward along the coast to Washington and Oregon, extending in 

 land to the Selkirk Mountains of British Columbia and the 

 Cascade Mountains of Washington. Westward IcK&fflorum oc 

 curs on the Alaska peninsula, in some of the Aleutian 'Islands, 

 and in eastern Asia. Coloradense is known only from high 

 elevations in the Rocky Mountains of Colorado, and is thus 

 separated by several hundred miles from the known range of 

 either of the others. Lamfcftorurn and pro stratum apparently 

 meet in British Columbia. All three species appear to belong 

 to the Canadian zone, with a tendency to overrun into the Hud- 

 sonian.
