EUPATORIUM L. 



E. BACLEANUM DC. 



This name is a synonym of the following : 



E. COMMERSONII (Cass.) Hieron. Engler's Bot. Jahrb., vol. 22. 



S. Brazil ; Argentinian pampas ; doubtful if it occurs in N. Patag. 

 D. 



E. BUNIIFOLIUM Hook, et Arn. Engler's Bot. Jahrb., vol. 22, p. 773. 



Syn. E. pinnatifidmn DC, E. virgatum Don. 

 Scarcely found in N. Patagon. D. 



P. 776 : For. E. pinnatifidum substitute E. buniifolium Hook. & Arn. 



Syn. E. pinnatifidmn DC., E. mrgatmn Don. 



Macloskie's statements of this plant's occurring both in the United States 

 and in N. Patagonia are hardly correct.. E. pinnatifidum DC. is consid- 

 ered a synonym of E. buniifolium Hook. & Arn. 



It should be deleted, as we have no evidence of its occurrence in Pat- 

 agonia ; the statement that it exists in Eastern United States is also prob- 

 ably erroneous. Spegazzini represents it as occurring in the Province 

 of Buenos Aires. D.
