 This species is related to S. ellipticus DC. and S. ellipticifolius 

 Hieron. From the former it differs in having smaller leaves and 

 a tomentulose inflorescence; and from the latter it differs in the 

 absence of glandular puherulence, longer petioles, and in the ab- 

 sence of conspicuous calyculiform bracts subtending the involucre.
