Passing by numerous transitions on the one hand to the more 
condensed typical S. lepida, on the other to var. elongata with its more 
elongate and more definitely terminal thyrsus. Often confused in the 
Herbarium with S. serotina Ait., which has the stems glabrous up to ` 
the inflorescence with its strongly secund branches, and the heads 
usually larger. In the East more often confounded with S. canadensis 
L. which has similar foliage and similarly pubescent stems, but very 
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 
and usually entire and the involucral bracts firmer and less attenuate.
