This species has so closely the habit and involucre of § Conoclinium 

 that it seems best to place it there provisionally, although the recepta- 

 cle is only moderately convex, considerably less so than is usual in the 

 section. Among the Colombian Eupatoriums of § Conoclinium this 

 new species approaches most nearly £. baUotacfoliumilBK., but differs 

 from it in its strictly opposite short-petioled leaves of oblong rather 

 than deltoid-ovate contour and of considerably firmer texture.
