The Indian Lettuce or Canker Lettuce of North-west 
America, a figure of which accompanies our illustration 
of Pyrola uliginosa, is also an interesting and pleasing 
plant. The type of P. bracteata, all the flowers of which 
are in bud, was collected by Dr. Scouler on the north- 
west coast of North America; the precise locality has 
not been recorded. The area it occupies is more 
restricted than that occupied by P. uliginosa; it extends 
from British Columbia to Idaho and California, in open 
coniferous woods. The material for our illustration was
