discussed the generic position of Mallinoa and shown that it is of the 
genus Eupatorium, where it approaches very closely the species E. 
bellidifolium Benth. At that time it seemed unwise to rename 
Mallinoa corymbosa under Eupatorium, from a suspicion that the plant 
might already have been somewhere so treated, which now proves to 
have been the case. Klatt misleadingly described 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. Mueller, 
is described above as E. choricephalum 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.
