This plant, which 1 take pleasure in naming for its discoverer, 

 Prof. James Fowler of Kingston, Ontario, bears such a close resem- 

 blance to B. Rail (or better B. Roberti) of the Old World that it is 

 by no means remarkable that it has of late been confused with that 

 species. It differs, however, in several features. The leaves are 

 more obtuse and are not nigrescent in drying, the achenes are 

 smaller and much more sharply beaked and the less petaloid calyx 

 lobes are oblong, not oval.
