14, 292).* This interesting little Crucifer has been rarely 

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

 place among the Crucifera\ It has already been referred 

 to several genera, and Dr. Robinson lias only doubtfully 

 named it Thclopodium. He says : " The problematic 

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

 leaves, purplish flowers and undivided stigma, may well 

 be referred to Thdopodium, from which it appears to 

 be distinguished only by its small size and slender 

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

 accbrding 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 Mountains 

 so far as we know.
