Vemonia incequiserrata Sch.-Bip. var. obtuaifolia Ghisebach, 1866, 

 p. 144.

 spec, orig., KU, S). 



The species differs from V. incequiserrata in its obtuse, 

 crenulate leaves with rounded base and in the many-flowered 

 heads. As to its floral characters, it comes rather near to 

 V. inazquiserrata. From V. aceratoides Gleason it is dis- 

 tinguished by its broader, always obtuse leaves and by its 

 many-flowered heads. A comparison of the structure of the 

 flowers will also afford good distinctions.
