1. Balsamorhiza careyana A. Gray, PI. Fenal. 81. 1849. 
Tyree Locauity: Idaho. ‘Sandy plains, Clear Water, on the Kooskooskie.”” Collected 
by Spalding. 
Rance: Eastern Washington, Eastern Oregon, and perhaps adjacent Idaho. 
SPECIMENS EXAMINED: Ritzville, Sandberg & Leiberg 166; Sprague, Sandberg & Leiberg, 
June, 1893; Ephrata to Ritzville, Griffiths d& Cotton 483; Prosser to Rattlesnake Mountains, 
Griffiths & Cotton 10; Wallula, Cotton 1052; Delight, Cotton 1004; Washtucna, Cotton 976; 
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.”’
