* Salix niphoclada Rydb. Last woods, east shore, Artillery 



Lake, August 6. 



This is a medium-sized shrubby willow of quite extensive dis- 

 tribution 



* Salix reticulata L. Last woods, east shore, Artillery Lake, 



August 6; Caribou Island, Great Slave Lake, July 21. 

 First seen on the subarctic islands in the eastern part of Great 

 Slave Lake, and common from there to and beyond the tree limit. 



* Salix rostrata Richards. Fort Smith, Mackenzie, June 22 and 



July 3; near Caribou Island, Great Slave Lake, July 21. 

 This is perhaps the commonest willow along the streams 

 throughout the region. It is one of the several shrubs called by 

 the natives "red willow." Its tough inner bark furnishes cord- 

 age, of which the Indians make nets and fish-lines. 



Abies balsamea (Linn.). Mill. 



The balsam poplar reaches a good size on the lower Athabaska, 

 but was not observed north of the delta. 



Juniperus sabina Linn. 



The creeping juniper is common in suitable places, dry and 

 usually rocky locations, throughout the wooded region. Noted 

 at tree limit on Artillery Lake. 



Juniperus nana Willd. 



Similar in distribution and habit to the creeping juniper, and, 

 like it, observed commonly at the tree limit. 



Myrica gale Linn. 



The sweet gale was common on the north shore of Great Slave 

 Lake, near the Mountain Portage. 



Calypso borealis Salisb. Noted on Little Buffalo River and 

 abundant on Et-then Island in Great Slave Lake.
