discussed the generic position of MalUnoa and shown that it is of the 

 genus Eiqxdorium, where it approaches very closely the species E. 

 bcllidifolium Benth. At that time it seemed unwise to rename 

 Mallinoa corymbosa under Eupatorimn, from a suspicion that the plant 

 might already have been somewhere so treated, which now proves to 

 ha^■e been the case. Klatt misleadingly j:lescribed the species as 

 shrubby. This is certainly not the case. It is an herbaceous peren- 

 nial, leafy chiefly at or near the base and with consequent subscapose 

 habit. The more leafy plant, long passing in herbaria as E. MucIIeri, 

 is described above as E. choriccphalum and may be readily separated 

 by its broadly ovate distinctly cordate leaves, distributed well into the 

 open inflorescence, as well as by many other characters.
