SMALL PYROLA 
Pyrola minor Linnaeus 
The small pyrola delights in wet places. We find it flourishing in 
bogs ot on oozing stream banks, usually in densely shaded situations. 
Flowering in midsummer, its rosy pink saucers lend a touch of color 
to its otherwise dull surroundings. The flowers vary greatly in depth 
of color, and occasionally they are white. They are smaller and fewer 
than those of the bog pytola, which is a species more generally dis- 
tributed and locally more abundant. 
The small pytola has a wide range in the colder parts of North 
America, extending from Massachusetts to Colorado and California, 
and northward to the Arctic regions. It grows also in Europe and Asia. 
The specimen sketched was obtained in the valley of the Pipestone 
River, about ten miles by trail north of Lake Louise, Alberta, Canada, 
at an altitude of 4,500 feet.
