The above separation of these much referred species is a 

 tentative one, and while based on m.y own observation of these 

 plants in the course of field study and subsequent comparison 

 in the Herbarium of the University of Minnesota, is made 

 with a view of calling attention to these perplexing plants and, 

 if possible, procuring more material for study. 



The plants referred to as Lithospermum longijiorum Goldie 

 are slender, branching, becoming procumbent, with narrowly 

 linear leaves, usually about one inch in length, and with a short, 

 whitish corolla, equalling in length the upper leaves or foli- 

 aceous bracts which surround the flowers. 



On the other hand the plants referred to as Lithospermum 

 longijiorum (Pqrsh) Spreng, are stout, erect, very rarely 

 branching above, with linear-lanceolate leaves from one and a 

 half to three inches in length, and with a long, yellow corolla, 

 normally one inch to an inch and a half in length, producing 

 cleistogenous flowers with short, inconspicuous corollas later 

 in the season.
