from Labrador. The other distinction which Willdenow 
observes of the leaves in one being nervosa, in the other 
venosa, remarked also by Mr. Salisbury, in Smith’s Flora 
Britannica, though not unfounded, is hardly sufficiently 
pointed for use, as the nerves in suecica sometimes take their 
origin from the midrib, and the veins in Canadensis are so 
strongly marked on the under side and so little divided, that 
most describers would call them nerves.” 
After due consideration of these various points, it seems 
advisable to make the present form a variety of C. Canaden- 
sis, as it resembles that species rather more than C. Suectca. 
Corallorhiza innata, R. Br. var. virescens, var. nov.—This 
variety differs from the type in the color of the flowers, which 
are a light yellowish-green. 
Banff, Alberta, June 14, 1904; Field, B. C., June 11, 1904. 
Senecio triangularis, Hook.—The typical form of the 
above species is abundant at Glacier, Lake Louise, and over 
other areas of the region now dealt with, but along the lower 
part of the Asulkan Trail it occurs interspersed with a 
remarkably luxuriant variety that attains a height of 4 
feet, which bears ample leaves that are three to five times the 
size of the typical form, but which most strikingly varies in 
the rudimentary condition or absence of the ray flowers in 
the capitula. The entire plant also is more hairy in char- 
acter.
