Leaves thick, roughish; basal and the lower stem-leaves petioled, obscurely 

 triple-nerved, obtuse or acutish, crenate-dentate, 7-15 cm. long, 8-25 mm. wide; 

 upper leaves gradually smaller, oblanceolate or linear-oblong, acute or acutish,

Solidago nemoralis arenfcola Burgess. Depressed, or prostrate, about 15 cm. high; 

 inflorescence dense, flattened, composing most of the plant. Sand hills, Cape Cod to L. I. 



Solidago pulcherrima A. Nelson, is the western representative of this species, ex- 

 tending east into Kans. and Neb. It differs in its pale color and narrower basal leaves, 

 but I have not been able to separate it specifically.
