are Escholtzii, Sternb. Rocky Mountains (7,000 feet), Aug. 18, ’74. I first 
obtained a specimen of this plant from Major Cameron, who found it on the 
summit of a mountain near the Kootanie Pass. A few days afterward, I 
found it growing in considerable abundance on the peaks near the Boundary 
Monument. It forms a dense, matted sod, and is generally seen growing be- 
tween stones in the shady and retired parts of the mountains, near melting 
snow banks. Most of the specimens were past flowering on the date men- 
tioned. Described by Sternberg from Northern Asia, but found also on the 
north west coast of America, lat. 59°, Behring’s Strait, and on the Arctic Sea 
shore, near Mackenzie River.
