 A species related to 5. Burkei Greenm., but distinguished readily 

 from it by the more or less flexuous stem, relatively narrow 

 oblong-oblanceolate basal leaves, remotely lobed lower stem- 

 leaves with broad rounded sinuses, and usually long pedunculate 

 heads. From 5. Balsamitae Muhl. to which certain of the above 

 specimens have been referred by some authors, S. multnomensis 

 is separated easily by the larger heads and longer involucral 

 bracts.
