1. Balsamorhiza careyana A. Gray, PI. Fendl. 81. 1849. 



Type locality: Idaho. "Sandy plains, Clear Water, on the Koo.skooskie." Collected 

 by Spalding. 



Rance: Eastern Washington, Eastern Oregon, and perhaps adjacent Idaho. 



Specimens examined: Ritzville, Sandberg d- Leiberg 166; Sprague, Sandbeiy cfc Leiherg,

 Prosser, Cotton 1084, 1105; Walla Walla region, Brandegee 891. 



Zonal distribution: Upper Sonoran. 



This species has not since been found near Lapwai, Spalding's "Clearwater" locality. 

 It is, however, abundant on the lower parts of Snake River and the type may have there 

 been gathered, as some of Spalding's specimens were collected "60 miles west of Clear- 

 water."
