erian Herbarium, but in tbe ' Flora Boreali-Americana ' they 

 are stated to be yellow ; and another variety is noticed as 

 having white flowers (viz. 8. albiflorum), to which the present 

 plant no doubt belongs. From some observations by Burke in 

 the Hookerian Herbarium, it would appear that the species 

 or forms of West American Erythremia retain their colours 

 over considerable areas, and that they are at least constant 

 races, whence for horticultural purposes the present will, no 

 doubt, bear a specific name.
