NOTES ON THE WILLOWS OF THE CHILLIWACK 



VALLEY, B.C. 



By J. M. Macoun. 



The number of species of Salix in the Chilliwack Valley is 

 remarkably small for that region, only four species having been 

 seen in igoi in the valley itself and five on the mountains on either 

 side of it. In the valley S. Sitchensis is common everwhere, and 

 was the only willow growing along the river between Chilliwack 

 Lake and the point at vvhich the river enters the Eraser Valley 

 with the exception of one clump of S. pseudomyrsinites Anders., 

 which grew on a gravel bar in the river, This species was also 

 found by a rivulet at an altitude of 6,000 feet. The other valley 

 species were S. caudata (Nutt.), collected at Chilliwack village, 

 and S. Lyallii, Heller, at Sumas Lake and by a stream flowing 

 into Chilliwack Lake.
