 collected, and there is still some uncertainty as to its true 

 place among the Crucifera?. It has already been referred

 S. salsugineum, Pall, with glabrous entire cordate-clasping 

 leaves, purplish flowers and undi^dded stigma, may well 

 be referred to Thelopodium, from which it appears to 

 be distinguished only by its small size and slender 

 habit." (Syn. Flora, p. 137). Its range in America, 

 according to Dr. Robinson, is " Rocky Mountains from 

 Colorado at South Park, Porter, to British America and 

 shores of the Arctic Sea, Richardson, according to Hooker, 

 I.e.," but it has never been found in our Rocky Moim tains 

 so far as we know.
