 of their scales.

 long. Cones ovoid 1|- - 2 inches long ; scales numerous, loosely im- 

 bricated, thin, ovate, of a beautiful pink colour before ripening, J

Larix Lyallii was discovered by Dr. Lyall when surgeon and 

 naturalist to the International Boundary Commission in British 

 Columbia in 1858, who found it growing near the timber line at 

 an elevation of nearly 7,000 feet in the Cascade Mountains. It has 

 a somewhat restricted distribution, occurring on mountain slopes 

 from 4,500 to 8,000 feet elevation in southern Alberta, British 

 Columbia, northern Washington and Montana. 



Young plants sent by Mr. F. R. S. Balfour were added to the 

 Bayfordbury collection in 1908. The photograph is that of a native 

 specimen collected by Dr. A. Henry in Montana.
