 larger than specimens from Point Barrow, on the Northwest 

 Pacific coast.

 Erigeron alpinus L- 



Found only by Dr. Burk. 

 Erigeron oompositus Pursh.

 Greenland vary much according to location, these are exactly like 

 Rocky Mountain specimens, and specimens of Nuttall from Walla 

 Walla on the Columbia River.

Varying in no degree from those in American alpine heights.
