SAND PHACELIA 
Phacelia linearis (Pursh) Holzinger 
We found the sand phacelia growing plentifully on a mound of 
disintegrated limestone in the Columbia River valley. The plant has 
dainty flowers, which are larger than those of many other Rocky 
Mountain phacelias. It flourishes in dry soils, blooming freely with 
a minimum of moisture. The phacelias are exclusively American 
plants, belonging to the Waterleaf Family. They are most abundant 
in the Western States, but several members of the group occur along 
the Atlantic coast, and others extend southward to the mountains 
of Guatemala. 
Sand phacelia has a wide range, from Utah to California, an north 
to British Columbia and Alberta. — 
The specimen sketched was obtained in the Columbia River val- 
ley, five miles from Radium Hot Springs, British Columbia, at an 
altitude of 2,500 feet.
