The species was 'collected at several stations and, with regard to its occur- 

 rence, Mr. Johansen writes : 



"Cape Bathurst. Grows among grasses, etc., on the clay-banks with which 

 the higher tundra behind falls off to the sandspit, and on the tundra itself. 

 Found both on the top and slopes of these clay-banks; in the former place the 

 vegetation is more stunted and scarcer than on the slopes and in the protected, 

 small gullies here. Growth somewhat prostrate and spreading, but twigs and 

 catkins protruding well from surrounding vegetation."
