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, and 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 ^,500 feet.
