the inflorescence with its strongly secund branches, and the heads 
usually larger. In the East more often confounded with S. canadensis

small heads (the involucre 2-2.8 mm. long) on strongly recurving 
branches. In its more pubescent extremes simulating the more 
southern S. altissima L., which has the very cinereous leaves thick
