* Aster subracemosus. 



Perennial, from a rootstock ; stem 5-6 dm. high, simple, strict, 

 sparingly strigose, terete ; leaves oblanceolate or linear, or the upper

 on the margins, entire ; inflorescence falsely racemose, often over 2 

 dm. long; heads about i cm. high, on bracted branchlets, 2-3, sel-
