Although this species in foliage and general form of the inflorescence 
slightly suggests E. macrophyllum L., it differs in many important 
details (fewer florets, cylindrical rather than campanulate involucre, 
glabrous receptacle, etc.) and is clearly of § Subimbricata. Although 
cylindrical in form the involucre does not have the texture or close 
imbrication which characterize § Cylindrocephala.
